What is the treatment for diarrhea?

BRAT diet: If your baby has a stomach virus, you could try pedialyte for a few feedings to see if she tolerates it better than formula. In a child taking solid foods, the "brat" diet (bananas-rice-apple sauce-toast) is recommended. Other starchy foods such as mashed potatoes, rice, and bland pasta will help to solidify the stools. Avoid juices such as apple, pear or prune as they may loosen the stools.

Fluids fluids fluids: Drinks plenty of fluids to keep up with the fluid losses. There are medications that can slow down the diarrhea such as lomotil, (diphenoxylat and atropine) but they may prolong the episode of the loose stools. Its better to let the body flush it out naturally, while you keep up with the fluid losses.

Yes: But which treatment depends on the cause of your diarrhea. There are non-specific treatments like over the counter Imodium (loperamide) which slow the gut down thus limiting symptoms. Other treatments include antibiotics, for bacterial causes of diarrhea, as well as anti-pararsitic, and toxin binding therapies (see c.Difficile diarrhea). That all said, the most important "treatment" is good hydration!
