Occasional stomach discomfort is usually nothing to worry about, likely just indigestion. But persistent, severe stomach pain is a different story. It might not be indigestion at all, but a sign of another illness.

Gallstones
Stomach pain could be a sign of gallstones. These hard deposits in the gallbladder block bile flow, leading to severe upper abdominal pain, especially after eating fatty foods.

Gastritis
Caused by infection, stress, or overusing painkillers, this is an inflammation of the stomach lining. It brings a burning pain, nausea, and bloating, often right after eating.
With gastroesophageal reflux disease (GERD), stomach acid often flows back into the esophagus. This can cause heartburn, stomach discomfort, and a sour taste in your mouth.

Appendicitis
Appendicitis causes severe pain in your lower right abdomen, often with a fever. If you also feel nauseous, see a doctor right away. Surgery is usually needed immediately.

Ulcer
Pain can come from sores in your stomach or small intestine, often due to H. pylori infection. This causes a burning pain that's worse on an empty stomach. If you have these symptoms, see a doctor.
