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 groupExamplesPossible clues
Functional dyspepsiaIndigestion without an obvious structural causeRecurring upper-abdominal discomfort, early fullness, bloating, or nausea
Reflux or other digestive conditionsGastroesophageal reflux disease or irritation of the upper digestive tractBurning behind the breastbone, sour fluid in the mouth, or symptoms worse when lying down
Stomach infection or ulcer-related problemsStomach infection, gastritis, or a stomach or duodenal ulcerPersistent pain, nausea, vomiting, or pain related to meals
Medicines and supplementsSome pain relievers, antibiotics, iron, and other medicines or supplementsSymptoms begin or worsen after starting or changing a product
Food or lifestyle triggersLarge or fatty meals, spicy foods, alcohol, caffeine, smoking, stress, or eating quicklySymptoms 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 patternWhat it may suggestWhat to do
AcuteA short-lived reaction to a meal, drink, medicine, stress, or another temporary triggerTry simple self-care if symptoms are mild and improving; seek urgent help for severe symptoms or red flags
SubacuteSymptoms lasting days to a few weeks may reflect an ongoing trigger, reflux, medication effect, infection, or another digestive problemReview triggers and medicines, and arrange medical advice if symptoms persist, worsen, or interfere with eating
Chronic or recurrentRepeated or long-lasting symptoms may be functional dyspepsia, reflux, ulcer-related disease, or another conditionBook 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.
