What It Means
What Is Indigestion?
Indigestion, also called dyspepsia, is discomfort or an unpleasant feeling in the upper abdomen after or around eating. It is a pattern of symptoms rather than always a single disease, and the underlying cause can vary.
Indigestion symptoms may include feeling full sooner than expected, uncomfortable fullness after a meal, upper-abdominal pain or burning, bloating, belching, and nausea. Symptoms vary from person to person, so what indigestion feels like is not exactly the same for everyone.
Emergency Warning Signs
When Indigestion May Be an Emergency
Seek urgent help
Do not assume severe symptoms are indigestion
Seek emergency care for severe or sudden chest or upper-abdominal pain, pressure or squeezing, or symptoms that could indicate a heart or other urgent medical problem. A heart attack can sometimes feel like indigestion, so do not self-diagnose.
- Pain spreading to the arm, jaw, back, or neck
- Shortness of breath, sweating, fainting, or severe weakness
- Vomiting blood or passing black stools
Possible Causes
Possible Causes of Indigestion
Indigestion may follow a large, fatty, spicy, or fast meal. Alcohol, caffeine, smoking, stress, and lying down soon after eating can also contribute.
| Cause group | Examples | Possible clues |
|---|---|---|
| Functional dyspepsia | Indigestion without an obvious structural cause | Recurring upper-abdominal discomfort, early fullness, bloating, or nausea |
| Reflux or other digestive conditions | Gastroesophageal reflux disease or irritation of the upper digestive tract | Burning behind the breastbone, sour fluid in the mouth, or symptoms worse when lying down |
| Stomach infection or ulcer-related problems | Stomach infection, gastritis, or a stomach or duodenal ulcer | Persistent pain, nausea, vomiting, or pain related to meals |
| Medicines and supplements | Some pain relievers, antibiotics, iron, and other medicines or supplements | Symptoms begin or worsen after starting or changing a product |
| Food or lifestyle triggers | Large or fatty meals, spicy foods, alcohol, caffeine, smoking, stress, or eating quickly | Symptoms follow a particular food, habit, or stressful period |
Persistent or recurrent indigestion can sometimes be related to an ulcer, gastroesophageal reflux disease, gallbladder or pancreatic disease, or another condition. The pattern of symptoms and any associated features help guide the right indigestion treatment and whether medical assessment is needed.
Duration Triage Table
What Indigestion May Mean by Duration
| Duration pattern | What it may suggest | What to do |
|---|---|---|
| Acute | A short-lived reaction to a meal, drink, medicine, stress, or another temporary trigger | Try simple self-care if symptoms are mild and improving; seek urgent help for severe symptoms or red flags |
| Subacute | Symptoms lasting days to a few weeks may reflect an ongoing trigger, reflux, medication effect, infection, or another digestive problem | Review triggers and medicines, and arrange medical advice if symptoms persist, worsen, or interfere with eating |
| Chronic or recurrent | Repeated or long-lasting symptoms may be functional dyspepsia, reflux, ulcer-related disease, or another condition | Book a medical review, especially for new or changing symptoms, weight loss, vomiting, swallowing problems, or severe pain |
Duration alone does not diagnose the cause of indigestion. Severity, age, medical history, medicines, and associated symptoms also affect how urgently you should seek care.
Relief Tips
Indigestion Relief Tips
- Eat smaller meals and slow down while eating.
- Avoid personal trigger foods and limit excess alcohol or caffeine.
- Remain upright after meals and avoid lying down soon after eating.
- Avoid smoking, which can aggravate digestive symptoms.
- Keep a symptom and food diary if you are unsure what triggers symptoms.
- For mild symptoms, consider whether changing meal size, timing, or food choices improves indigestion relief.
Antacids, alginates, H2 blockers, or proton pump inhibitors may help depending on the symptom pattern. Follow the product label, check for medicine interactions, and ask a pharmacist or clinician if you are unsure which over the counter treatment for indigestion is appropriate.
When to See a Doctor
When to See a Doctor for Indigestion

- Seek prompt medical advice for trouble or pain when swallowing.
- Seek prompt medical advice for repeated vomiting or loss of appetite.
- Ask for assessment if you have anemia or unusual tiredness.
