Diarrhea

Diarrhea is the frequent passage of loose stools and an increase in fluidity and frequency of stool. Diarrhea classifies as osmotic, secretory, infective and deranged motility depending on etiology or mechanism.

Osmotic diarrhea: it may occur because of the present excess solutes in the intestine that leads to non-absorption of water. Osmotic diarrhea can also happen when there is a shortage in an enzyme which is necessary for the digestion of certain carbohydrates or when you ingest a poorly absorbed substance.

Secretory diarrhea: this type of diarrhea result when the rate of discharge of fluid by the intestinal wall into the lumen overpass the rate of absorption. Some other factors such as certain hormones, poisons, drug, laxatives may cause secretory diarrhea.

Infectious diarrhea: disruption of intestinal epithelium by viral or bacterial pathogens leads to infectious diarrhea.

Causes of diarrhea after bariatric surgery

Diarrhea after bariatric surgery can be related to fatty acids passing directly into the colon which causes irritation, while in the normal condition they should absorb in the small intestine. Another reason is passing rapidly of undigested food through the gastrointestinal tract. More addition, sorbitol which found in berries, fruits or used as an artificial sweetener is another factor that may cause diarrhea. Sorbitol cannot absorb well in the GL tract and will be fermented in the colon and causes gas and diarrhea.

Dumping syndrome is another reason for diarrhea for patients who have undertaken gastric sleeve surgery. Dumping syndrome occurs due to the rapid emptying of the stomach content into the small intestine.
