How to get rid of diarrea?

If over a few days,: See a doc. It may not be anything serious, but if it is it can be very bad to let it go on for long. Becoming dehydrated is not at all a good idea and that can happen quickly. For the first day or two, you can try over-the-counter remedies (ask the druggist) and eat or avoid certain foods - eat bananas, blueberries, rice, toast, yogurt, tea - avoid dairy, fatty & sweet foods. But see a doc soon!
