Go slow with diet. Most of the times after having stomach problems the stomach remains very sensitive. You must slowly advance your diet to a healthy diet. Start with fluids such as apple juice, gator-aid, clear sodas (sprite, 7-up). If you feel well then eat some bland solids such as bananas, saltine crackers, toast, rice, mashed potatoes, grilled chicken. Go slow and with small portions at first.
