Why does my stomach hurt after I eat?
Stomach pain after eating is most often caused by indigestion, acid reflux, gastritis, a peptic ulcer, gallbladder problems, food intolerances such as lactose intolerance, irritable bowel syndrome or simply eating too much, too fast or too much fat. Less common causes include pancreatitis, slow stomach emptying, celiac disease and, in older adults with vascular disease, reduced blood flow to the intestines.
| Pain pattern | Possible cause |
|---|---|
| Burning in the upper middle belly soon after eating | Gastritis, ulcer, indigestion |
| Burning rising into the chest | Acid reflux (GERD) |
| Pain under the right ribs after fatty meals | Gallstones or gallbladder inflammation |
| Severe upper pain spreading to the back | Pancreatitis (emergency) |
| Cramping and bloating hours later | Food intolerance, IBS |
| Fullness and nausea after small meals | Functional dyspepsia, gastroparesis |
| Pain 15 to 60 minutes after meals with weight loss in older adults | Reduced intestinal blood flow (needs prompt evaluation) |
Is stomach pain after eating a sign of an ulcer?
It can be. Stomach (gastric) ulcers often cause burning or gnawing upper abdominal pain that may worsen soon after eating, while duodenal ulcers more often hurt on an empty stomach and may briefly improve with food. Ulcers are commonly caused by H. pylori infection or anti-inflammatory pain relievers and are confirmed with testing or upper endoscopy.

Can the gallbladder cause pain after eating?
Yes. Gallstones can cause attacks of steady pain under the right ribs or in the upper middle abdomen, often 30 minutes to a few hours after a fatty or large meal. The pain may spread to the right shoulder or back and can last several hours, sometimes with nausea. Fever, yellowing of the skin or eyes, or pain that does not go away needs urgent care.

When is stomach pain after eating an emergency?
Get emergency care for severe stomach pain after eating that does not ease, pain spreading to the back with vomiting, a hard or swollen belly, fever, yellowing of the skin or eyes, vomiting blood or black stools, or chest pain, shortness of breath or sweating. These can signal pancreatitis, a gallbladder infection, a bleeding ulcer, a blockage or a heart problem.
Emergency warning signs
- Severe or constant pain, or pain spreading to the back
- Fever, persistent vomiting or a hard belly
- Yellow skin or eyes
- Vomiting blood or black stools
- Chest pain, shortness of breath or sweating
How can I reduce stomach pain after meals?
To reduce stomach pain after meals, eat smaller portions slowly, limit fatty, fried and spicy foods, avoid alcohol, stay upright for two to three hours after eating, notice and reduce trigger foods, and avoid frequent anti-inflammatory pain relievers. These steps help with indigestion, reflux and gallbladder symptoms but do not replace treatment of an ulcer or gallstones.
- Choose smaller, lower-fat meals
- Eat slowly and stop before you are overly full
- Limit alcohol, spicy foods and late-night eating
- Ask your doctor before taking ibuprofen or naproxen regularly
Tip: Note timing and location
Write down how soon pain starts after eating, where you feel it and which foods were involved. These three details narrow the cause more than anything else.
How is the cause of pain after eating found?
A gastroenterologist starts with your history and an exam, then chooses tests based on the pattern: H. pylori testing and upper endoscopy for stomach causes, an abdominal ultrasound for gallstones, blood tests including liver tests and lipase for gallbladder or pancreas problems, breath tests for intolerances, and sometimes CT imaging or a gastric emptying study.
