Loose watery bowel movements, commonly called diarrhea, are caused by infections (viral, bacterial, or parasitic), contaminated food or water, food intolerance, stress, or side effects of medications. The intestine moves contents too quickly, preventing normal water absorption. Treatment focuses on preventing dehydration with oral rehydration salts, clear fluids, and light foods. Probiotics may help restore gut flora. In infectious cases, doctors may prescribe targeted medicines; antiparasitic options like nitazoxanide are sometimes used under supervision. Maintaining hygiene, safe drinking water, and proper food handling reduces risk. Healthcare providers sourcing nitazoxanide wholesale should ensure quality, compliance, and appropriate medical guidance globally responsibly.
