What is the treatment for chronic diarrhea?

The treatment is specific according to its etiology, although symptomatic support is fundamental to avoid complications such as dehydration and malnutrition.
Antibiotic therapy would be used if there is suspicion of an infectious agent, especially if it is frequent in a geographic area.
Difenoxylate and loperamide are high potency antidiarrheals.
Octreotide subcutaneously is useful in diarrhea secondary to carcinoid syndrome and other neuroendocrine tumors, in diarrhea favored by chemotherapy, dumping syndrome and associated with short bowel syndrome.
