Diagnosis

Tests that may be done
- Blood tests to check for infection or signs of inflammation
- Breath test or stool test for Helicobacter pylori (H. pylori) bacteria
- Endoscopy: a thin tube with a camera is passed through your mouth into your stomach to look for ulcers or other problems
- Ultrasound or CT scan of the belly area
What to expect at your appointment
The doctor will work with you to understand what might be causing your symptoms. Most tests are simple and do not hurt. If an endoscopy is needed, you will be given medicine to help you relax. The results can help guide the right treatment.
Treatment
Treatment depends on the cause. Many cases get better with self-care and lifestyle changes. If there is an underlying condition like an ulcer or acid reflux, your doctor can recommend treatments to help.
Self-care at home
- Eat smaller, more frequent meals instead of large ones
- Chew food slowly and thoroughly
- Avoid foods that trigger your symptoms, such as fatty or spicy dishes
- Stay upright for at least 2 to 3 hours after eating
- Reduce stress with relaxation techniques like deep breathing or gentle exercise
Medical treatments
Your doctor may suggest medicines that reduce stomach acid or help protect the stomach lining. These include antacids, H2 blockers, or proton pump inhibitors, which are available over the counter or on prescription. If an H. pylori infection is found, antibiotics are used. Always follow your doctor's advice and never take more than the recommended dose.
When is surgery considered?
Surgery is rarely needed for stomach discomfort after eating. It may be considered if there is a severe problem like a blockage or a large ulcer that does not heal with medicine.
