Just getting over the stomach virus and now i'm constipated with lots of gas pain. what should i do?

Gastroenteritis: If you had a lot of diarrhea it is not unusual to go without bowel movements for a few days after. If you are uncomfortable with intestinal gas collection,in addition to avoiding gassy foods, drinking hot water and applying a hot water bottle to the abdomen helps break down the gas and moves it down for passing. Taking simethicone after meals prevents gas build-up. Senokot (senna) helps constipation.
