What Does It Mean When Your Stomach Hurts and You Have a Fever?
Medically reviewed by Linda Girgis | MD, Girgis Family Medicine on August 21st, 2026.
Stomach pain with fever typically indicates an infection or inflammation in your digestive system. Common causes include gastroenteritis (stomach flu), food poisoning, appendicitis, or other bacterial infections. Gastroenteritis affects 179 million Americans annually and usually resolves within 1-3 days with rest and hydration. However, severe abdominal pain with high fever (over 101°F), persistent vomiting, or pain in the lower right abdomen requires immediate medical attention as it may signal appendicitis or other serious conditions. Seek emergency care if symptoms worsen rapidly or you experience dehydration signs like dizziness or reduced urination.
