Diarrhea can be acute (short term) such as in viral or bacterial infections or it can be medication induced like overuse of antibiotics or laxatives.
Usually replenishment of fluids and electrolytes and avoidance of certain meds can stop the diarrhea. Diarrhea can be chronic (long term)if associated with lactose intolerance, inflammatory bowel disease, or irritable bowel. Tests are usually needed.
