Having loose motions for three days after eating out suggests a possible mild infection or food-related irritation. It’s important to stay well-hydrated by drinking plenty of fluids like oral rehydration solutions, but avoid sugary or caffeinated drinks.

You can consider taking medication like loperamide (available as Lopamide tablets) to help reduce diarrhea, but only after consulting a doctor, especially since it requires a prescription. If you experience symptoms like high fever, severe abdominal pain, blood in stools, or signs of dehydration (dizziness, very little urine), seek immediate medical attention.

For now, follow these steps:

• Drink plenty of fluids, including traditional Indian options like buttermilk or coconut water.
• Eat light, bland foods such as khichdi, boiled potatoes, or plain rice.
• Avoid spicy, oily, or heavy meals until symptoms improve.
• Consult a gastroenterologist or a general physician for proper evaluation and treatment.
