A stomach infection with pain and discomfort is often caused by food poisoning, viral gastroenteritis, or sometimes a mild bacterial infection. It can lead to symptoms like stomach cramps, loose motions, nausea, bloating, or general weakness. In most cases, it settles within a few days with rest and proper care, as the body clears the infection on its own. The most important step is to stay well hydrated by drinking water, ORS, coconut water, or light soups to prevent dehydration. Eat simple, easy-to-digest foods like rice, curd, banana, or toast, and avoid oily, spicy, and outside food until you recover. Resting well also helps the stomach heal faster. Depending on the cause and symptoms, a doctor may prescribe medicines for pain, vomiting, acidity, or infection, but the right treatment should be decided after evaluation. It is not safe to take antibiotics on your own, since not all stomach infections require them. You should seek medical care if there is a high fever, blood in the stools, repeated vomiting, signs of dehydration, or if the pain is getting worse instead of improving.
