DIET FOR DISEASES OF THE SMALL INTESTINE

function

Main function of the Small intestine is the absorption of water, minerals and vitamins as well as decomposition products from complex Carbohydrates (Starch), fats and protein This happens. under the influence of bile and the digestive enzymes from the pancreas.
The anatomy of the small intestine creates the ideal conditions for this, as the presence of mucosal folds and intestinal villi (Protuberances) the surface is increased by a factor of 600.

Diseases of the small intestine

At Diseases of the small intestine As a result, nutrient utilization will be impaired. Other reasons for this are insufficient production of bile salts and digestive enzymes from the pancreas. All of these nutrient use disorders graze under the umbrella term Malassimilation summarized. If the cause of this disorder is insufficient digestion of the nutrients, one speaks of maldigestion or indigestion.
Is the root cause Insufficient absorption of nutrients through the intestinal mucosa is referred to as malabsorption or resorption insufficiency. Normally, the absorption of nutrients is already complete in the upper sections of the small intestine.
However, if a part of the lower small intestine is surgically removed, the so-called short bowel syndrome occurs with, depending on the length of the missing intestinal sections, an insufficient supply of nutrients to the patient.

In the last section of the small intestine (terminal ileum) become Vitamin B12 and absorbed the bile salts. If this section of the intestine is missing, the result is a vitamin B12 deficiency, which is achieved by injecting the vitamin into the muscle can be easily fixed. The increased transfer of bile salts into the Large intestine can diarrhea and there is also a loss of bile salts with the stool. This causes the bile acid concentration in the bile to drop and the digestion of fat and consequently the absorption of fat-soluble vitamins are disturbed.
The small intestine also plays an important role as a Immune organ and has a barrier function for germs in the intestine.
