Alternative Names: Spastic Colon
Irritable bowel syndrome (IBS) is a common disorder of the intestines affecting perhaps 20% of the adult population that leads to pain, gassiness, bloating, and changes in bowel habits. Symptoms include constipation, diarrhea, or a painful but unsuccessful urge to move the bowels. Through the years, IBS has been called by many names – colitis, mucous colitis, spastic colon, spastic bowel, and functional bowel disease. Most of these terms are inaccurate. Colitis, for instance, means inflammation of the large intestine (colon). IBS, however, does not cause inflammation and should not be confused with another disorder, ulcerative colitis.
Often IBS is just a mild annoyance, but for some people it can be disabling. They may be unable to go to social events, to go to work, or to travel even short distances.
The colon, which is about 6 feet long, connects the small intestine with the rectum and anus. The major function of the colon is to absorb water and salts from digestive products that enter from the small intestine. Two quarts of liquid matter enter the colon from the small intestine each day. This material may remain there for several days until most of the fluid and salts are absorbed into the body. The stool then passes through the colon by a pattern of movements to the left side of the colon, where it is stored until a bowel movement occurs. Movements of the colon propel the contents slowly back and forth but mainly toward the rectum. A few times each day strong muscle contractions move down the colon pushing fecal material ahead of them. Some of these strong contractions result in a bowel movement.
Ordinary events such as eating and distention from gas or other material in the colon can cause the colon to overreact in a person with IBS, or certain medicines and foods may trigger spasms. Sometimes the spasm delays the passage of stool, leading to constipation. Chocolate, milk products and large amounts of alcohol are frequent offenders. Caffeine causes loose stools in many people, but it is more likely to affect those with IBS. Researchers also have found that women with IBS may have more symptoms during their menstrual periods, suggesting that reproductive hormones may exacerbate the problem. People with IBS sometimes pass mucus with their bowel movements.
The researchers treated the patients who tested positive for SIBO with a 10-day course of antibiotics. Tests at the end of that time found that 25 of 47 patients had no bacterial overgrowth present, and that 12 of them had no IBS symptoms, while the symptoms were "significantly reduced" in the other 13. The symptoms were also reduced in the patients in which some SIBO was still detected, suggesting that if treatment had been continued until it was completely eliminated, perhaps with an alternative antibiotic, better results would have been obtained.
Eating causes contractions of the colon and normally this response may cause an urge to have a bowel movement within 30 to 60 minutes after a meal. In people with IBS, the urge may come sooner and be accompanied by cramps and diarrhea. The strength of the response is often related to the number of calories consumed, particularly the amount of fat in a meal. Fat in any form (animal or vegetable) is a strong stimulus of colonic contractions.
For many people, eating a proper diet lessens IBS symptoms. Before changing your diet, it is a good idea to keep a journal noting which foods seem to cause distress.
The pain is generally located in the lower abdomen, although the location and type of pain can vary. Emotional stress and eating can exacerbate the pain, whereas a bowel movement often provides some relief.
October, 2013: Researchers from the Alimentary Pharmabiotic Centre at University College Cork reported that psychological factors such as anxiety and depression may be the central drivers of IBS, rather than the inflammation originating in the gut itself. The most commonly-diagnosed psychiatric disorder in IBS patients is depression: one study reported that 38% of IBS patients had clinically-confirmed depression. It is believed that IBS results from a complex interplay between psychological and biological factors.
Hypercoagulation may be a major causative factor for Irritable Bowel Disease because it deprives the bowel of blood.
Some bacterial infections of the small bowel increase passive intestinal permeability. IBS has been studied in patients with diarrhea, cramps and specific food intolerances. Abnormal fecal flora has been a consistent finding, with a decrease in the ratio of anaerobes to aerobes, apparently due to a deficiency of anaerobic flora. Previous exposure to antibiotics – metronidazole in particular – was associated with the development of this disorder.
The enterocytes of the small intestines are the body's largest consumers of glutamine, accounting for about 40-50% of glutamine consumption.
Enteric-coated Peppermint oil has been used in treating the irritable bowel syndrome in Europe for many years. In one double-blind cross-over study, it was shown to significantly reduce the abdominal symptoms.
There are quite a few people who use marijuana to control the symptoms of abdominal pain and nausea associated with irritable bowel syndrome. Some make the claim that this helps more than any other thing they have tried.
Dietary fiber may lessen IBS symptoms in many cases. High-fiber diets may cause gas and bloating, but within a few weeks these symptoms often go away as the body adjusts to the diet: IBS can be treated in most cases simply by increasing the intake of dietary fiber and eliminating food allergies.
The synthetic polymers methylcellulose and polycarbophil have been found to be the most effective fibers or bulk-forming laxatives for use in the treatment of Irritable Bowel Syndrome (IBS). Neither are found naturally in food sources. Methylcellulose is used as a food additive/thickener. Both are available over the counter in commercial products such as Citrucel (methylcellulose) and Fibercon (polycarbophil), among others.
Large meals can cause cramping and diarrhea for those with IBS. Symptoms may be eased if you eat smaller meals more often or just eat smaller portions. This should help, especially if your meals are low in fat and high in carbohydrates such as pasta, rice, whole-grain breads and cereals, fruits, and vegetables.
People with spastic colon are often fiber-intolerant and have a tendency to like fats because they produce a feeling of wellbeing. They often respond well – sometimes even dramatically so – to a multiple digestive enzyme formula.
A study involving zinc supplementation in inflammatory bowel disease illustrated the importance of taking adequate supplementation, but not too much. In this study, excess amounts of zinc caused tissue injury and impaired wound healing [Cario et al. 2000]. However, relative zinc deficiencies, especially in the elderly, are common in the United States [Andrews et al. 1999].
This bacteria becomes cultured in milk, and is not destroyed by pasteurization. Para-T crosses the species barrier to infect and cause disease in humans. Occasionally, the milk-borne bacteria will begin to grow in the human host, and irritable bowel syndrome and Crohn's disease results. The USDA estimates that 30% of America's dairy herds contain cows infected with Para-T.
