Gastritis is a sore and upset stomach. It happens when something irritates the stomach lining. Many things can cause it. These include an infection such as the flu or something you ate or drank. Medicines or a sore on the lining of the stomach (ulcer) also can cause it. Your belly may bloat and ache. You may belch, vomit, and feel sick to your stomach.
