Diarrhea Clinically Symptoms
Certain foods, such as certain fruits, beans and morning used as sugar substitutes in some diets, sweets and chewing gum can cause diarrhea osmótica.
Several facts characterized clinically osmotic diarrhea:
- disappears with the patient fasting or interrupting the intake of absor able solute bit
- osmotic gradient is observed in the faeces: fecal osmolarity is very high compared to plasma (normal is isotonic, ie equal to that of plasma);
- Primarily fecal sodium is usually <60 mOsm, lower than the plasma
- the stool volume excreted is usually less than 1 liter per 24 h
- the generally lower fecal pH 5 (acid) by bacterial fermentation of unabsorbed carbohydrates
- tendency to dehydration with high sodium content in plasma
- is self-limiting and of short duration, stopping as soon as you stop eating osmotic products.
Osmotic Diarrhea
It is characterized by increased non-absorbable components in the digestive tract due to inadequate absorption of nutrients present in the light intestinal. As a result, no liquids are absorbed and remain in the lumen. It is seen mainly in malabsorption syndromes, such as celiac disease or pancreatic disorders, in which the secretion of digestive enzymes is altered. Another possible cause is the use of osmotic laxatives (which act to relieve constipation by retaining water in the intestine).
In healthy individuals, too much magnesium or vitamin C or undigested lactose can produce osmotic diarrhea. A person with lactose intolerance can have digestive problems if you eat a high amount of dairy products, because unabsorbed lactose remains in the intestine. This results in increased fluid retention and gas production, causing diarrhea osmótica.7 Similar effects can be observed in people with fructose malabsorption. Sugar alcohols such as sorbitol (often present in sugar-free foods) are absorbed with difficulty and can cause diarrhea diarrhea osmótica.8 acid is also produced as a result a marked erythema perinatal.
