Go to the ER or call your local emergency number if indigestion comes with chest pressure, shortness of breath, cold sweating, faintness, pain spreading to the arm, jaw, or back, or vomiting blood or passing black, tarry stools. Sudden, severe, or constant abdominal pain also needs urgent assessment. Mild symptoms that settle may not require the ER, but symptoms that persist or worsen should be reviewed by a healthcare professional.
Indigestion often causes uncomfortable fullness after eating, upper abdominal burning, bloating, or nausea. These symptoms are frequently related to digestive problems, but some urgent conditions can feel similar. The most important consideration is whether your symptoms suggest an emergency, particularly a heart attack or gastrointestinal bleeding. Knowing which warning signs require immediate attention can help you decide whether to seek emergency care or contact a healthcare professional for further evaluation.
What does indigestion usually feel like?
Indigestion, also called dyspepsia, describes discomfort in the upper abdomen. It can involve a burning sensation, feeling full shortly after starting a meal, uncomfortable fullness after eating, bloating, nausea, or belching. According to the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), indigestion may happen occasionally or become a longer-lasting problem.
These symptoms may occur after eating a large meal or consuming foods that upset your stomach. However, indigestion is not always related to food, and the way it feels cannot reliably identify its cause. Some potentially serious conditions produce discomfort that resembles ordinary indigestion, so new, unusual, or concerning symptoms deserve attention.
When should you go to the ER for indigestion?
Seek emergency medical care if your indigestion-like symptoms could indicate a heart attack, serious internal bleeding, or another acute abdominal problem. Do not wait for symptoms to become unbearable or assume that discomfort is harmless because it resembles a familiar digestive problem.
1. You have possible heart attack symptoms
A heart attack does not always feel like the sudden, crushing chest pain people often expect. The American Heart Association (AHA) explains that heart attack symptoms can include chest discomfort, upper-body pain, shortness of breath, nausea, sweating, and lightheadedness. Some people experience symptoms that resemble indigestion rather than recognizing them as a possible heart problem.
Warning signs that can accompany indigestion-like discomfort include:
- Pressure, tightness, fullness, or pain in the chest.
- Pain or discomfort that spreads to the arm, shoulder, back, neck, or jaw.
- Shortness of breath, with or without chest discomfort.
- Cold sweating, nausea, or unusual lightheadedness.
- Sudden unusual weakness or discomfort in the upper abdomen, particularly when other concerning symptoms occur.
These are examples of possible warning signs, not a checklist for determining whether you are having a heart attack. If symptoms suggest a possible heart attack, call your local emergency number immediately. Emergency medical services can begin assessment and treatment during transport. Do not drive yourself to the hospital when a heart attack is suspected.
2. You vomit blood or notice black, tarry stools
Vomiting blood, material that resembles coffee grounds, or passing black, tarry stools can indicate bleeding in the digestive tract. The Mayo Clinic's guidance on gastrointestinal bleeding recommends immediate medical care for these signs. Bleeding may occur alongside abdominal discomfort and can sometimes lead to weakness, dizziness, or fainting.
Do not treat suspected digestive tract bleeding as routine indigestion or wait for it to resolve at home. Seek emergency care, especially if you also feel faint, have difficulty breathing, experience chest discomfort, or develop sudden weakness. If someone collapses or shows signs of serious blood loss, call emergency services immediately.
3. You have sudden or severe abdominal pain
Sudden, severe, or persistent abdominal pain should not automatically be attributed to indigestion. It may require urgent assessment, particularly when it is new, worsening, or accompanied by repeated vomiting or other concerning changes. The Mayo Clinic's guidance on indigestion also identifies persistent or severe abdominal discomfort, repeated vomiting, difficulty swallowing, and yellowing of the skin or eyes as reasons to seek prompt medical care.
Go to the ER when abdominal pain is sudden or severe, is worsening rapidly, or occurs with signs of a possible medical emergency. Other symptoms, such as trouble swallowing, unexplained weight loss, or recurring vomiting, also warrant prompt clinical evaluation. A healthcare professional can determine whether emergency testing is necessary.
When can indigestion be managed without an ER visit?
A single episode of mild indigestion that settles on its own, without emergency warning signs, may not require an emergency department visit. If you otherwise feel well and the discomfort is improving, contacting a primary care professional may be more appropriate if you need medical guidance.
However, contact a healthcare professional if your symptoms last longer than a few days, change noticeably, keep returning, or interfere with eating or daily activities. MedlinePlus, a health information service of the U.S. National Library of Medicine, advises medical evaluation for persistent or changing indigestion, unexplained weight loss, difficulty swallowing, and other concerning symptoms. Seek urgent care rather than waiting for a routine appointment if your condition worsens.
Recurring indigestion may be associated with conditions such as acid reflux, inflammation of the stomach lining, ulcers, or medication effects. A clinician can review your symptoms, medical history, and medicines to decide what evaluation or treatment may be appropriate.
Should you wait to see whether an antacid helps?
No. Do not delay emergency care to test whether an antacid or other indigestion medicine relieves symptoms that could indicate a heart attack. Heart-related discomfort and digestive symptoms can feel similar, and the response to a medicine cannot reliably distinguish between them.
The American Heart Association's guidance on heartburn versus a heart attack advises seeking immediate medical attention when you are unsure whether chest discomfort is caused by heartburn or a heart problem. If emergency warning signs are present, call for help even if symptoms are mild, come and go, or seem to improve temporarily.
What should you tell a healthcare professional?
If you seek medical attention, describe when the discomfort began, where you feel it, whether it spreads to another area, and whether it started during activity or after a meal. Mention other symptoms, including vomiting, changes in bowel movements, sweating, dizziness, or shortness of breath. Tell the clinician about your medical history and all medicines you take, including nonprescription pain relievers and supplements.
When emergency warning signs are present, do not delay calling for help to collect this information. If possible, have someone assist you while you wait for emergency services.
