In the treatment of diarrhea, what is considered the mainstay of treatment?

• A. Bland diet
• B. Hydration
• C. Antibiotics
• D. Bowel Rest

Answer: (B)

Hydration is the mainstay of diarrhea treatment because the most immediate danger from diarrheal illness is loss of fluids and electrolytes, which can lead to dehydration and shock. The priority is to restore circulating volume and electrolyte balance. For most patients, oral rehydration therapy with a glucose-electrolyte solution effectively replaces water, sodium, potassium, and bicarbonate losses. The glucose component helps sodium and water absorption in the gut, making oral rehydration both safe and efficient. If someone cannot take fluids by mouth or if dehydration is severe, intravenous fluids are used to rapidly restore hydration. After rehydration begins, normal feeding can usually resume; strict bowel rest or depriving the gut of food isn’t necessary. Antibiotics are reserved for specific infectious causes, not for routine management.
