Diarrhea is not a typical or primary symptom of a heart attack, but in some cases, especially among women, older adults, and people with diabetes, gastrointestinal symptoms may appear during a heart attack. These can include nausea, vomiting, indigestion, abdominal discomfort, and in rare cases, diarrhea.
The most recognized symptoms of a heart attack include:
- Chest pain or pressure (often described as squeezing or tightness)
- Pain radiating to the arm, jaw, back, or neck
- Shortness of breath
- Cold sweats
- Lightheadedness or dizziness
- Unusual fatigue
In women, heart attack symptoms can be more subtle, sometimes presenting as:
- Nausea or vomiting
- Indigestion-like discomfort
- Anxiety
- Shortness of breath without chest pain
- Sudden, unexplained tiredness
When should you worry about diarrhea?
If diarrhea happens alongside any of the classic heart attack symptoms — especially chest pressure, sweating, or shortness of breath — it should be taken seriously. These combined signs could point to a cardiac event that requires emergency care.
Bottom Line:
While diarrhea by itself is usually a gastrointestinal issue, if it occurs with other symptoms of a heart attack, it’s important to seek immediate medical attention. It’s always better to be cautious, as heart attack symptoms can vary widely.
