Magnesium is a mineral needed by every cell of your body. About half of your body's magnesium stores are found inside cells of body tissues and organs, and half are combined with calcium and phosphorus in bone. Only 1% is found in the blood. Your body works very hard to keep blood levels of magnesium constant.
Magnesium is needed for more than 300 biochemical reactions in the body. It helps maintain normal muscle and nerve function, keeps heart rhythm steady, and bones strong. It is also involved in energy metabolism and protein synthesis.
Causes & Development
Treatment with diuretics (water pills), some antibiotics, and some cancer medicines such as Cisplatin, can increase the loss of magnesium in urine. Poorly-controlled diabetes increases loss of magnesium in urine, causing a depletion of magnesium stores.
Gastrointestinal problems, such as malabsorption disorders, can cause magnesium depletion by preventing the body from using the magnesium in food. Chronic or excessive vomiting and diarrhea may also result in magnesium depletion. The loss of magnesium through diarrhea and fat malabsorption usually occurs after intestinal surgery or infection, but it can occur with chronic malabsorptive problems such as Crohn's disease, gluten sensitive enteropathy, and regional enteritis. Individuals with these conditions may need extra magnesium. The most common symptom of fat malabsorption, or steatorrhea, is passing greasy, offensive-smelling stools.
Many people do not get enough magnesium from their diet for reasons including the following:- The amount of magnesium in the soil in which the food is grown may be reduced.
- Magnesium can be lost in the processing and refining of foods and in making oils from the magnesium-rich nuts and seeds. Nearly 85% of the magnesium in grains is lost during the milling of flours.
- Soaking and boiling foods can leach magnesium into the water, so the "pot liquor" from cooking vegetables may be high in magnesium and other minerals.
- Oxalic acid in vegetables such as rhubarb, spinach and chard, and phytic acid in some grains may form insoluble salts with magnesium, causing it to be eliminated rather than absorbed.
- Supplemental vitamin D or calcium reduces magnesium uptake.
- Diets high in phosphorus (meat, milk products, lentils, seeds, beans, nuts, chocolate, peanut butter, bran) reduce magnesium uptake.
- Magnesium elimination is increased in people who use alcohol, caffeine or excess sugar, or who take diuretics or birth control pills.
- Magnesium is absorbed toward the end of the small intestine. If any portion of this area (called the ileum) has been removed, magnesium absorption will be reduced.
Signs & Symptoms
Signs of magnesium deficiency include confusion, disorientation, loss of appetite, depression, muscle contractions and cramps, tingling, numbness, abnormal heart rhythms, coronary spasm, and seizures.
Diagnosis & Tests
Doctors will measure blood levels of magnesium whenever a magnesium deficiency is suspected.
While magnesium deficiency is fairly common, it is frequently overlooked as a source of problems. The reason is that serum magnesium levels (the test most doctors use) do not reflect actual body stores of magnesium. Blood levels are kept within the normal range at the expense of other tissues. When deficiency does occur, it is usually due to excessive loss of magnesium in urine, gastrointestinal system disorders that cause a loss of magnesium or limit magnesium absorption, or a chronically low intake of magnesium.
Treatment & Prevention
When levels are mildly depleted, increasing dietary intake of magnesium can help restore blood levels to normal. Eating at least five servings of fruits and vegetables daily, and choosing dark-green leafy vegetables often, as recommended by the Dietary Guidelines for Americans, the Food Guide Pyramid, and the Five-a-Day program, will help adults at-risk of having a magnesium deficiency consume recommended amounts of magnesium. When blood levels of magnesium are very low, an intravenous drip (IV drip) may be needed to return levels to normal. Magnesium tablets also may be prescribed, but some forms, in particular magnesium salts, can cause diarrhea.
What is the health risk of too much magnesium?
Dietary magnesium does not pose a health risk, however very high doses of magnesium supplements, which may be added to laxatives, can promote adverse effects such as diarrhea. Magnesium toxicity is more often associated with kidney failure, when the kidney loses the ability to remove excess magnesium. Very large doses of laxatives also have been associated with magnesium toxicity, even with normal kidney function. The elderly are at risk of magnesium toxicity because kidney function declines with age and they are more likely to take magnesium-containing laxatives and antacids.
Signs of excess magnesium can be similar to magnesium deficiency and include mental status changes, nausea, diarrhea, appetite loss, muscle weakness, difficulty breathing, extremely low blood pressure, and irregular heartbeat.
Complications
Magnesium and blood pressure. Evidence suggests that magnesium may play an important role in regulating blood pressure. Diets that provide plenty of fruits and vegetables, which are good sources of potassium and magnesium, are consistently associated with lower blood pressure. The DASH study (Dietary Approaches to Stop Hypertension) suggested that high blood pressure could be significantly lowered by a diet high in magnesium, potassium, and calcium, and low in sodium and fat. In another study, the effect of various nutritional factors on incidence of high blood pressure was examined in over 30,000 U.S. male health professionals. After four years of follow-up, it was found that a greater magnesium intake was significantly associated with a lower risk of hypertension. The evidence is strong enough that the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure recommends maintaining an adequate magnesium intake as a positive lifestyle modification for preventing and managing high blood pressure.
Magnesium and heart disease. Magnesium deficiency can cause metabolic changes that may contribute to heart attacks and strokes. There is also evidence that low body stores of magnesium increase the risk of abnormal heart rhythms, which may increase the risk of complications associated with a heart attack. Population surveys have associated higher blood levels of magnesium with lower risk of coronary heart disease. In addition, dietary surveys have suggested that a higher magnesium intake is associated with a lower risk of stroke. Further studies are needed to understand the complex relationships between dietary magnesium intake, indicators of magnesium status, and heart disease.
Magnesium and osteoporosis. Magnesium deficiency may be a risk factor for postmenopausal osteoporosis. This may be due to the fact that magnesium deficiency alters calcium metabolism and the hormone that regulates calcium. Several studies have suggested that magnesium supplementation may improve bone mineral density, but researchers believe that further investigation on the role of magnesium in bone metabolism and osteoporosis is needed.
Magnesium and diabetes. Magnesium is important to carbohydrate metabolism. It may influence the release and activity of insulin, the hormone that helps control blood glucose levels. Elevated blood glucose levels increase the loss of magnesium in the urine, which in turn lowers blood levels of magnesium. This explains why low blood levels of magnesium (hypomagnesemia) are seen in poorly controlled type 1 and type 2 diabetes.
In 1992, the American Diabetes Association issued a consensus statement that concluded: "Adequate dietary magnesium intake can generally be achieved by a nutritionally balanced meal plan as recommended by the American Diabetes Association." It recommended that "... only diabetic patients at high risk of hypomagnesemia should have total serum (blood) magnesium assessed, and such levels should be repleted (replaced) only if hypomagnesemia can be demonstrated".

Conditions that suggest Magnesium Requirement: | | | | | Circulation | Cardiomyopathy| | Myocardial magnesium was measured in 8 young patients (mean age 32) with ventricular tachycardia of less than 30 seconds in duration who underwent endomyocardial biopsy. Histologically, 4 had myocarditis and 1 had right-ventricular dysplasia. The other 3 patients had a cardiomyopathy with electron microscopic findings consistent with intracellular calcium overload, possibly due to reduced intracellular magnesium. Myocardial magnesium content was lower in the 4 with cardiomyopathic and dysplastic lesions than in the 4 with inflammatory lesions (myocarditis) and 8 controls. 10gm magnesium over 24 hours caused a resolution of ventricular tachycardias and a greater than 80% reduction in ventricular extrasystoles. No response was seen in the 4 patients with inflammatory lesions. [Lancet: 1019, 1987] |
Atherosclerosis| | Experimental studies have demonstrated a correlation between magnesium deficiency and atherosclerosis, but without any clear evidence to determine the mechanisms involved. Magnesium deficiency may affect the atherosclerosis process through several different mechanisms. |
Arrhythmias/Dysrhythmias| | Myocardial magnesium was measured in 8 young patients (mean age 32) with ventricular tachycardia of less than 30 seconds in duration who underwent endomyocardial biopsy. Myocardial magnesium content was lower in the 4 with cardiomyopathic and dysplastic lesions than in the 4 with inflammatory lesions (myocarditis) and 8 controls. 10gm magnesium over 24 hours caused a resolution of ventricular tachycardias and a greater than 80% reduction in ventricular extrasystoles.

 Bruxism (Clenching/Grinding Teeth)| | According to Ploceniak, prolonged magnesium administration nearly always provides a cure for bruxism. This confirms an earlier report which claimed remarkable reductions and sometimes disappearance in the frequency and duration of grinding episodes in six patients who took assorted vitamins and minerals (which included 100mg of magnesium) for at least five weeks. When the supplement intake stopped, the symptoms returned. [Bruxism and Magnesium, My Clinical Experiences Since 1980, by C. Ploceniak (Translated from the French by James Michels)] |
Susceptibility to Hangovers| | It is possible that some of the hangover symptoms related to alcohol are in part due to magnesium depletion. |

Red Blood Cell magnesium levels in PMS patients have been shown to be significantly lower than in normal subjects. The deficiency is characterized by a generalized hyperesthesia syndrome (with generalized aches and pains), and a lower premenstrual pain threshold. One clinical trial of magnesium in PMS showed a reduction of nervousness in 89%, mastalgia in 96%, and weight gain in 95%. |

Risk factors for Magnesium Requirement:
Magnesium Requirement suggests the following may be present: | | | | | Addictions | Alcohol-related Problems| | People who abuse alcohol are at high risk for magnesium deficiency because alcohol increases urinary excretion of magnesium. Low blood levels of magnesium occur in 30-60% of alcoholics, and in nearly 90% of patients experiencing alcohol withdrawal. In addition, alcoholics who substitute alcohol for food will usually have lower magnesium intakes. Medical doctors routinely evaluate the need for extra magnesium in this population. |

GLOSSARY
Adrenaline (Epinephrin, Epinephrine)
A hormone secreted by the adrenal medulla that is released into the bloodstream in response to physical or mental stress, as from fear or injury. It initiates many bodily responses, including the stimulation of heart action and an increase in blood pressure, metabolic rate, and blood glucose concentration.
Anorexia Nervosa (Anorexia)
An eating disorder characterized by excess control - a morbid fear of obesity leads the sufferer to try and limit or reduce their weight by excessive dieting, exercising, vomiting, purging and use of diuretics. Sufferers are typically more than 15% below the average weight for their height/sex/age and typically have amenorrhea (if female) or low libido (if male). 1-2% of female teenagers are anorexic.
Antacid (Antacids)
Neutralizes acid in the stomach, esophagus, or first part of the duodenum.
Anxiety
Apprehension of danger, or dread, accompanied by nervous restlessness, tension, increased heart rate, and shortness of breath unrelated to a clearly identifiable stimulus.
Atherosclerosis
Common form of arteriosclerosis associated with the formation of atheromas which are deposits of yellow plaques containing cholesterol, lipids, and lipophages within the intima and inner media of arteries. This results in a narrowing of the arteries, which reduces the blood and oxygen flow to the heart and brain as well as to other parts of the body and can lead to a heart attack, stroke, or loss of function or gangrene of other tissues.
Biopsy
Removal of a sample of tissue from a living being for diagnosis. A pathologist later uses a microscope to look for certain features, such as cancer cells, in the sample. A fine-needle aspiration biopsy involves inserting a thin needle to remove a small amount of tissue, sometimes using CT or ultrasound to guide the needle. A core biopsy involves obtaining a sample of tissue with a thick needle or by inserting a thin, lighted tube (laparoscope) into a small incision in the abdomen. Another biopsy method is to remove tissue during an operation.
Bruxism
Prolonged, unintentional grinding and clenching of the teeth, usually occurring during sleep. 'Bruxers' are often unaware that they have developed this habit. Symptoms include abraded/chipped teeth (in extreme cases, waking up with tooth chips in the mouth); facial pain; oversensitive teeth; tense facial and jaw muscles; headaches; dislocation of the jaw; damage to the tooth enamel, exposing the inside of the tooth; a popping or clicking in the temporomandibular joint (TMJ); tongue indentations; damage to the inside of the cheek.
Calcium
The body's most abundant mineral. Its primary function is to help build and maintain bones and teeth. The body also needs calcium to carry nerve signals, keep the heart functioning, contract muscles, clot blood and maintain healthy skin. Calcium helps control blood acid-alkaline balance, plays a role in cell division, muscle growth and iron utilization, activates certain enzymes, and helps transport nutrients through cell membranes. Calcium also forms a cellular cement called ground substance that helps hold cells and tissues together.
Cancer
Refers to the various types of malignant neoplasms that contain cells growing out of control and invading adjacent tissues, which may metastasize to distant tissues.
Carbohydrates (Carbohydrate)
The sugars and starches in food. Sugars are called simple carbohydrates and found in such foods as fruit and table sugar. Complex carbohydrates are composed of large numbers of sugar molecules joined together, and are found in grains, legumes, and vegetables like potatoes, squash, and corn.
Centimeter (Centimeters, cm)
A metric unit of length equaling one hundredth of a meter, or ten millimeters. There are 2.54 millimeters in one inch.
Chronic (Chronicity)
Usually referring to chronic illness: Illness extending over a long period of time.
Chronic Renal Failure (Chronic Renal Insufficiency, Kidney Failure, Renal Insufficiency)
(CRF) Irreversible, progressive impaired kidney function. The early stage, when the kidneys no longer function properly but do not yet require dialysis, is known as Chronic Renal Insufficiency (CRI). CRI can be difficult to diagnose, as symptoms are not usually apparent until kidney disease has progressed significantly. Common symptoms include a frequent need to urinate and swelling, as well as possible anemia, fatigue, weakness, headaches and loss of appetite. As the disease progresses, other symptoms such as nausea, vomiting, bad breath and itchy skin may develop as toxic metabolites, normally filtered out of the blood by the kidneys, build up to harmful levels. Over time (up to 10 or 20 years), CRF generally progresses from CRI to End-Stage Renal Disease (ESRD, also known as Kidney Failure). Patients with ESRD no longer have kidney function adequate to sustain life and require dialysis or kidney transplantation. Without proper treatment, ESRD is fatal.
Cramp (Cramping, Cramps)
A sudden, involuntary, painful muscular contraction.
Crohn's Disease (Crohn's)
Chronic inflammatory disease of the gastrointestinal tract. The most common symptoms are abdominal pain, often in the lower right area, and diarrhea. Rectal bleeding, weight loss, and fever may also occur. Bleeding may be serious and persistent, leading to anemia.
Diabetes Mellitus (Diabetes, Diabetic, Diabetics)
A disease with increased blood glucose levels due to lack or ineffectiveness of insulin. Diabetes is found in two forms; insulin-dependent diabetes (juvenile-onset) and non-insulin-dependent (adult-onset). Symptoms include increased thirst; increased urination; weight loss in spite of increased appetite; fatigue; nausea; vomiting; frequent infections including bladder, vaginal, and skin; blurred vision; impotence in men; bad breath; cessation of menses; diminished skin fullness. Other symptoms include bleeding gums; ear noise/buzzing; diarrhea; depression; confusion.
Diarrhea
Excessive discharge of contents of bowel.
Diuretic (Diuretics)
An agent increasing urine flow, causing the kidneys to excrete more than the usual amount of sodium, potassium and water.
Dysplasia
Abnormal development of tissue.
Enteritis
Sometimes Enteritis regionalis: Localized inflammation of the intestine.
Gastrointestinal (GI, GI Tract)
Pertaining to the stomach, small and large intestines, colon, rectum, liver, pancreas, and gallbladder.
Gestational Diabetes
Gestational diabetes is defined as any degree of glucose intolerance with the onset or first recognition occurring during pregnancy. Many pregnant women do not notice any symptoms of diabetes, but urine and blood tests may show that they have it. Symptoms of diabetes may include thirst, weight loss, eating too much, urinating in large quantities and unexplained fatigue.
Glucose
A sugar that is the simplest form of carbohydrate. It is commonly referred to as blood sugar. The body breaks down carbohydrates in foods into glucose, which serves as the primary fuel for the muscles and the brain.
Glycosuria
Sugar in the urine, from hyperglycemia, diabetes, or most simply, sugar binges.
Gram (gm, gms, Gramme, Grammes, Grams)
A metric unit of weight, there being approximately 28 grams in one ounce.
Hallucination (Hallucinations)
A false or distorted perception of objects or events, including sensations of sight, sound, taste, smell or touch, typically accompanied by a powerful belief in their reality.
Hangover (Hangovers)
A commonly used nonmedical term for the disagreeable physical effects following excessive consumption of alcohol (or the use of other drugs).
Hormones (Hormone)
Chemical substances secreted by a variety of body organs that are carried by the bloodstream and usually influence cells some distance from the source of production. Hormones signal certain enzymes to perform their functions and, in this way, regulate such body functions as blood sugar levels, insulin levels, the menstrual cycle, and growth. These can be prescription, over-the-counter, synthetic or natural agents. Examples include adrenal hormones such as corticosteroids and aldosterone; glucagon, growth hormone, insulin, testosterone, estrogens, progestins, progesterone, DHEA, melatonin, and thyroid hormones such as thyroxine and calcitonin.
Hyperesthesia
An abnormal or pathological increase in sensitivity to sensory stimuli, as of the skin to touch or the ear to sound.
Hyperglycemia (Hyperglycemic)
Elevations of blood glucose, either from the various types of diabetes, excessive sugar intake (short term) or from adrenalin or stimulant causes.
Hypertension
High blood pressure. Hypertension increases the risk of heart attack, stroke, and kidney failure because it adds to the workload of the heart, causing it to enlarge and, over time, to weaken; in addition, it may damage the walls of the arteries.
Ileum
The lower two-thirds of the small intestine, ending in the ileocecal valve and emptying into the cecum of the colon. The last foot of the ileum is the only absorption site available for important dietary substances such as vitamin B12, folic acid, some essential fatty acids, fat soluble vitamins, and recycled bile acids.
Insulin
A hormone secreted by the pancreas in response to elevated blood glucose levels. Insulin stimulates the liver, muscles, and fat cells to remove glucose from the blood for use or storage.
Intravenous Infusion (IV)
A small needle placed in the vein to assist in fluid replacement or the giving of medication.
Kidneys (Kidney, Renal)
Bean-shaped organs, each about the size of a fist. They are located near the middle of the back, just below the rib cage. The kidneys are sophisticated reprocessing machines, each day handling about 50 gallons of blood to sift out about half a gallon of waste products and extra water. The waste and extra water become urine, which flows to the bladder through tubes called ureters. The actual filtering occurs in tiny units inside the kidneys called nephrons. Every kidney has about a million nephrons. In a nephron, a glomerulus -- which is a tiny blood vessel, or capillary -- intertwines with a tiny urine-collecting tube called a tubule. A complicated chemical exchange takes place, as waste materials and water leave your blood and enter your urinary system. The kidneys recycle chemicals such as sodium, phosphorus, and potassium and thus regulate their levels. Renal: Pertaining to the kidneys.
Lactation (Lactate, Lactates, Lactating)
Production of milk; period after giving birth during which milk is secreted in the breasts.
Laxative (Laxatives)
A substance (food, herb, chemical) that stimulates evacuation of the bowels. Examples include cascara sagrada, senna, castor oil, aloe vera, bisacodyl, phenolphthalein and many others.
Lesion (Lesions)
Any damage to tissue structure or function; an abnormal change in body tissue caused by disease or injury. A scar is a lesion, as is cancer, a stomach ulcer or a pimple.
Liver (Hepatic)
The largest and one of the most complex organs of the body, the liver is responsible for much of the metabolism of fats, proteins and carbohydrates. It is the site of much of the body's detoxification. It is connected very closely with digestion and the regulation of blood sugar, among many other functions. Found behind the ribs on the right side of the abdomen, it has many important functions such as removing harmful material from the blood, making enzymes and bile that help digest food, and converting food into substances needed for life and growth. Hepatic: Pertaining to the liver.
Magnesium
An essential mineral. The chief function of magnesium is to activate certain enzymes, especially those related to carbohydrate metabolism. Another role is to maintain the electrical potential across nerve and muscle membranes. It is essential for proper heartbeat and nerve transmission. Magnesium controls many cellular functions. It is involved in protein formation, DNA production and function and in the storage and release of energy in ATP. Magnesium is closely related to calcium and phosphorus in body function. The average adult body contains approximately one ounce of magnesium. It is the fifth mineral in abundance within the body--behind calcium, phosphorus, potassium and sodium. Although about 70 percent of the body's magnesium is contained in the teeth and bones, its most important functions are carried out by the remainder which is present in the cells of the soft tissues and in the fluid surrounding those cells.
Malabsorption
Improper utilization of needed and available nutrients, either from impaired digestive function (such as B12 being unabsorbed because of gastritis), impaired absorption (poor Vitamin E absorption because of an inflamed ileum) or impaired transport (the diminished blood proteins of the advanced alcoholic). There are other causes as well.
Metabolism (Metabolic, Metabolize, Metabolizes, Metabolizing)
The chemical processes of living cells in which energy is produced in order to replace and repair tissues and maintain a healthy body. Responsible for the production of energy, biosynthesis of important substances, and degradation of various compounds. Also defined as the sum total of changes in an organism in order to achieve a balance (homeostasis): Catabolic burns up, anabolic stores and builds up; the sum of their work is metabolism.
Milligram (mg, Milligrams)
0.001 or a thousandth of a gram.
Mineral (Minerals)
Plays a vital role in regulating many body functions. They act as catalysts in nerve response, muscle contraction and the metabolism of nutrients in foods. They regulate electrolyte balance and hormonal production, and they strengthen skeletal structures.
Myocarditis
Inflammation of heart muscle. It can be mild, with virtually no noticeable symptoms, or more serious, leading to weakening of the heart muscle. It can then cause heart failure (with symptoms of shortness of breath, fatigue, fluid accumulation in the lungs, etc.) as well as heart rhythm irregularities from inflammation and/or scarring of the electrical system of the heart.
Nausea
Symptoms resulting from an inclination to vomit.
Osteoporosis
A disease in which bone tissue becomes porous and brittle. The disease primarily affects postmenopausal women.
Oxalic Acid
A substance that when joined with calcium in the body forms insoluble salts and hinders iron absorption from food. It is found in such vegetables as spinach, chard and rhubarb.
Pancreas (Pancreatic)
Opposite the liver and behind the stomach, the pancreas has two main functions - to manufacture various enzymes for digestion, and to release hormones to help control the body's use of carbohydrates. It releases insulin to help each cell absorb glucose to burn as energy. In this way, insulin controls the amount of sugar (glucose) in the blood. Proper pancreatic function is very important: too much, too little, or no insulin production can be life-threatening. Some of the chemicals released by the pancreas are not hormones, but stimulate other glands to make hormones. Once again, balance is necessary. Nutritional requirements for the pancreas are many. Research indicates that chromium vitamins C, E, B-complex, calcium, magnesium and potassium are especially important.
Phosphorus
The second most abundant mineral in the body, found in every living cell. It is involved in the proper functioning of both muscles and nerves. It is needed for metabolic processes of all cells, to activate many other nutrients, and to form energy-storage and energy-releasing compounds. The phosphorus content of the body is approximately 1% of total body weight. Phosphorus combines with fats to form phospholipids. Combined with calcium, it gives strength and rigidity to the bones and teeth.
Postmenopause (Postmenopausal)
The postmenopausal phase of a woman's life begins when 12 full months have passed since the last menstrual period and any menopausal symptoms have become milder and/or less frequent.
Potassium
A mineral that serves as an electrolyte and is involved in the balance of fluid within the body. Our bodies contain more than twice as much potassium as sodium (typically 9oz versus 4oz). About 98% of total body potassium is inside our cells. Potassium is the principal cation (positive ion) of the fluid within cells and is important in controlling the activity of the heart, muscles, nervous system and just about every cell in the body. Potassium regulates the water balance and acid-base balance in the blood and tissues. Evidence is showing that potassium is also involved in bone calcification. Potassium is a cofactor in many reactions, especially those involving energy production and muscle building.
Premenstrual Syndrome (PMS)
PMS consists of various physical and/or emotional symptoms that occur in the second half of the menstrual cycle, after ovulation. The symptoms begin about midcycle, are generally the most intense during the last seven days before menstruation and include: acne; backache; bloating; fatigue; headache; sore breasts; changes in sexual desire; depression; difficulty concentrating; difficulty handling stress; irritability; tearfulness.
Protein (Proteins)
Compounds composed of hydrogen, oxygen, and nitrogen present in the body and in foods that form complex combinations of amino acids. Protein is essential for life and is used for growth and repair. Foods that supply the body with protein include animal products, grains, legumes, and vegetables. Proteins from animal sources contain the essential amino acids. Proteins are changed to amino acids in the body.
Red Blood Cell (Erythrocyte, Erythrocytes, RBC, Red Blood Cells)
Any of the hemoglobin-containing cells that carry oxygen to the tissues and are responsible for the red color of blood.
Seizure (Seizures)
While there are over 40 types of seizure, most are classed as either partial seizures which occur when the excessive electrical activity in the brain is limited to one area or generalized seizures which occur when the excessive electrical activity in the brain encompasses the entire organ. Although there is a wide range of signs, they mainly include such things as falling to the ground; muscle stiffening; jerking and twitching; loss of consciousness; an empty stare; rapid chewing/blinking/breathing. Usually lasting from between a couple of seconds and several minutes, recovery may be immediate or take up to several days.
Serum
The cell-free fluid of the bloodstream. It appears in a test tube after the blood clots and is often used in expressions relating to the levels of certain compounds in the blood stream.
Small Intestine (Small Bowel)
The small intestine lies between the stomach and the large intestine. It is about 6 meters (20 feet) long and its primary function is to digest (break down) food and absorb nutrients (vitamins, minerals, proteins, carbohydrates, and fats). The small intestine makes up more than 70% of the length and 90% of the surface area of the gastrointestinal (GI) tract.
Sodium
An essential mineral that our bodies regulate and conserve. Excess sodium retention increases the fluid volume (edema) and low sodium leads to less fluid and relative dehydration. The adult body averages a total content of over 100 grams of sodium, of which a surprising one-third is in bone. A small amount of sodium does get into cell interiors, but this represents only about ten percent of the body content. The remaining 57 percent or so of the body sodium content is in the fluid immediately surrounding the cells, where it is the major cation (positive ion). The role of sodium in the extracellular fluid is maintaining osmotic equilibrium (the proper difference in ions dissolved in the fluids inside and outside the cell) and extracellular fluid volume. Sodium is also involved in nerve impulse transmission, muscle tone and nutrient transport. All of these functions are interrelated with potassium.
Spasm
Involuntary contraction of one or more muscle groups.
Steatorrhea
The presence of undigested fat in the feces. This may be the result of failing to inoculate fatty foods with enough surfactant (biliary soap) to digest them, the failure of the lower small intestine to absorb them, or simply too much fat for even normal digestion to handle. Sometimes this can indicate liver, gall bladder or lipid metabolism diseases. Usually the causes are subclinical and treatable with less invasive approaches such as herbs.
Stroke (Stroke-Type Event)
A sudden loss of brain function caused by a blockage or rupture of a blood vessel that supplies the brain, characterized by loss of muscular control, complete or partial loss of sensation or consciousness, dizziness, slurred speech, or other symptoms that vary with the extent and severity of the damage to the brain. The most common manifestation is some degree of paralysis, but small strokes may occur without symptoms. Usually caused by arteriosclerosis, it often results in brain damage.
Syndrome
A medical condition characterized by a collection of related symptoms (what the patient feels) and signs (what a doctor can observe or measure).
Ventricular Tachycardia
Excessively rapid heart beat due to uncontrolled ectopic focus in the ventricle.
Vitamin D
A fat-soluble vitamin essential to one's health. Regulates the amount of calcium and phosphorus in the blood by improving their absorption and utilization. Necessary for normal growth and formation of bones and teeth. For Vitamin D only, 1mcg translates to 40 IU.
