Remedies for loose stool include hydration and a bland diet, according to Everyday Health. Over-the-counter medications such as bismuth subsalicylate, or Pepto Bismol, and loperamide, sold as Imodium, also help remedy loose stool.
Hydration replaces the fluid that the body loses during diarrhea and can involve ingesting sports drinks and clear liquids, including water and clear broth, notes Everyday Health. However, a patient with loose stool should avoid drinks that contain alcohol, caffeine and sugar, as they exacerbate the symptoms of diarrhea. A bland diet eaten to remedy diarrhea could include rice, banana, toast and applesauce. The patient can also improve his condition by avoiding a particular food that causes his loose stool.
