Evaluating your likely current (and near future) state of health means taking into account the risk factors — such as removal of section of small bowel — that affect you. Our medical diagnosis tool, The Analyst™, identifies major risk factors by asking the right questions.
Have you had a Small Bowel Resection, a procedure in which a section of the small intestine is removed?
Possible responses:→ No
→ Don't know
→ Less than 50cm (20 inches)
→ More than 50cm (20 inches)
In evaluating magnesium levels in patients with small bowel resection, it was found that while serum magnesium was not abnormally low, but both urinary and muscle magnesium concentration decreased with increasing resection length. Muscular fatigue was also positively correlated to a pathologically low muscle magnesium concentration. Results suggest that clinically important magnesium deficiency occurs in patients with resections exceeding 75cm.
If food passes through the intestine too rapidly (for example due to reduced length), there is not enough time for proper digestion and absorption to be completed.
Extensive small intestinal resection patients are at risk for developing selenium deficiency due to impaired absorptive capacity.
If surgery leaves less than 200cm (about 7 feet) of viable small bowel, the risk for developing short-bowel syndrome is high.
Resection of the bowel increases the risk of vitamin B12 malabsorption. Even 7% to 10% of individuals with serum vitamin B12 levels in the 200-400pg/mL range have developed neuropsychiatric complications of vitamin B12 deficiency. Previously there was only concern when levels were below 200pg/mL.
Ileal resection can lead to malabsorption of both divalent cations (such as calcium and magnesium) and fat-soluble vitamins A, D, E and vitamin K.
