small bowel malabsorption syndrome
Introduction
Introduction to intestinal malabsorption syndrome Intestinal malabsorption syndrome is a syndrome of small intestine caused by various reasons, such as digestion of the small intestine, so that nutrients can not be absorbed normally, and excreted from the feces, causing nutritional deficiency, also known as digestive malabsorption syndrome. Because patients have diarrhea, the stool is thin and large, and contains more oil, also known as steatorrhea. Patients may have weight loss, mild tenderness in the abdomen, abnormal sensation in the extremities of the extremities, glossitis or ulceration of the tongue, psoriasis-like coloration, edema, concave nails, muscle tenderness, clubbing (toe) and other signs. basic knowledge The proportion of illness: 0.001% Susceptible people: no specific population Mode of infection: non-infectious Complications: anemia, malnutrition
Cause
Causes of intestinal malabsorption syndrome
Exogenous invasion (30%):
Exogenous evils invade the human body, can invade the spleen and stomach through the meridians, and can also directly commit the middle of the coke. The external evils are cold, heat, heat and humidity are common. Among them, there are many people who are exposed to moisture. Covering the diarrhea, all due to the spleen and stomach, the cause of diarrhea, the most injured in wet evil. Wet evil can trap the spleen, causing the spleen to lose health, spleen deficiency can be wet, wet and trapped spleen yang, so the spleen does not transport wet, wet intestines, sputum into diarrhea.
Injury to the diet (35%):
If the diet is not knotted or not, it can damage the spleen and stomach, causing the dysfunction of transport, and the water valley stops and stagnate, and the fine emblem is vented. According to modern research, the disease is mainly in the north of China, where the incidence is higher than that of the south. Barley, wheat, rye, oatmeal (commonly known as gluten) has a protein soluble in ethanol, which may be the cause of the disease. The main play is caused by toxic chlorotin damage to the small intestine mucosa.
Insufficient endowment (20%):
Congenital genetic defects may be one of the pathogenesis of this disease, which is insufficient endowment and weak body. Or due to illness and deficiency, can lead to spleen and stomach transport no power, gas sag, water valley dross mixed.
Prevention
Prevention of intestinal malabsorption syndrome
1, it is best to use high calorie, high protein, high vitamin, easy to digest, non-irritating low fat diet.
2, the elderly are well-infected with malabsorption syndrome, mainly related to the degenerative changes of the digestive system in the elderly. After the elderly, the small intestine villi becomes shorter, the absorption area decreases, and the pancreas gradually shrinks, which can promote or aggravate the absorption of malabsorption. Sign.
3, should limit physical labor, should not live in a hot environment.
Complication
Complications of intestinal malabsorption syndrome Complications, anemia, malnutrition
As nutrient malabsorption can cause weight loss, anemia, etc., it can also lead to water and electrolyte metabolism disorders.
Symptom
Symptoms of intestinal malabsorption syndrome Common symptoms Weak abdominal pain, abdominal distension, diarrhea, weight loss, diarrhea, diarrhea, night blind edema, edema
History and symptoms:
The number of diarrhea, duration, fecal appearance and volume, 80%-97% of patients have diarrhea, typically steatorrhea, light stool, a lot of color, oily or foamy, more stench, stool times from several times to ten Repeated times, sometimes intermittent diarrhea, abdominal pain, abdominal distension is rare, and should pay attention to ask whether there is weight loss, fatigue, hand and foot spasm, paresthesia, stomatitis, corneal dryness, night blindness, edema and other malnutrition symptoms, past examination and treatment It also helps with diagnosis.
Physical examination found:
Patients may have weight loss, mild tenderness in the abdomen, abnormal sensation in the extremities of the extremities, glossitis or ulceration of the tongue, psoriasis-like coloration, edema, concave nails, muscle tenderness, clubbing (toe) and other signs.
Examine
Examination of intestinal malabsorption syndrome
Most of the large cell anemia, serum electrolytes, plasma albumin, cholesterol, and even folic acid, vitamin B12 water levels decreased, fecal lipids> 6g / d, dextrose absorption test <3g, vitamin B12 absorption test <8% - 10%, when the intestinal flora is dysfunctional, 14C-glycocholate breath test is positive, gastrointestinal barium meal pays attention to whether the intestine is dilated, effusion and expectorant deposit "wax tube" sign, endoscopic examination of small intestine villi, crease Variety.
Diagnosis
Diagnosis and differential diagnosis of intestinal malabsorption syndrome
Can be diagnosed based on clinical symptoms and laboratory tests.
The disease should be identified mainly with tuberculous peritonitis, megacolon and food intolerance diarrhea.
Food intolerance refers to a complex allergic disease in which the human immune system treats one or more foods entering the human body as harmful substances, thereby producing an excessive protective immune response against these substances and producing food. Specific IgG antibodies, IgG antibodies form immune complexes (type III allergic reactions) with food particles, which can cause inflammatory reactions in all tissues (including blood vessels), and manifest as symptoms and diseases of various systemic systems.
