Loose motions with stomach pain after eating outside food, like fried chicken, is often due to mild food poisoning or stomach infection. This happens when the stomach gets irritated by bacteria, oily food, or contamination, and usually improves in a day or two with proper care. Right now, the most important thing is to keep yourself hydrated because the body loses water quickly during diarrhoea. Drink water, oral rehydration solution, or light fluids in small sips throughout the day. Stick to simple foods like rice, bananas, curd, toast, or boiled potatoes and avoid oily, spicy, or heavy meals until your stomach settles. Rest is also important because the gut needs time to recover. A light antidiarrheal or stomach-soothing medicine may sometimes be used for short-term relief, but it is better to take it only after proper advice based on your symptoms. If diarrhoea becomes very frequent, or if you notice high fever, blood in stools, severe weakness, or ongoing vomiting, it is important to seek medical care without delay, as you may need specific treatment.
