Delhi-belly is a type of gastroenteritis, characterized by inflammation of the stomach and intestines, leading to symptoms such as diarrhea, abdominal cramps, vomiting, and fever. The condition is usually caused by consuming contaminated food or water that contains bacteria, viruses, or parasites. Travelers to areas with poor sanitation, such as India, Southeast Asia, and Latin America, are at a higher risk of contracting Delhi-belly.
