How is diarrhea treated?

For low-stage diarrhea, the treatment usually requires supplying lots of fluids to make up for the amount that is lost. This means that you need to drink more water or electrolyte replacement beverages, such as sports drinks.

In more serious cases, you may get fluids into your body through intravenous therapy. If your diarrhea is caused by bacterial infection, you doctor may prescribe antibiotics.

You doctor or pharmacist may suggest using an oral rehydration solution (or oral rehydration therapy – a type of fluid replacement used to prevent or treat dehydration especially that due to diarrhea) to prevent dehydration.

Rehydration solutions can provide your body with glucose, salt and other important minerals that are lost during dehydration. Oral rehydration solution is suitable for both children and adults, which is also available at local pharmacies without prescription.
