PRACTICAL HEALTH · SYMPTOMS
🔥 Heartburn
Heartburn is a burning sensation often related to acid reflux. Chest discomfort, however, should not automatically be assumed to come from the digestive system.
What should you notice?
- Whether symptoms occur after eating or when lying down.
- Sour or acidic taste.
- Upper abdominal or behind-the-breastbone burning.
- Nausea, vomiting or trouble swallowing.
- Unintentional weight loss or black stool.
Possible causes
These are examples, not a diagnosis. The same symptom can have many different causes.
- Acid reflux or gastroesophageal reflux disease.
- Indigestion.
- Foods or drinks that trigger symptoms.
- Some medicines.
- Other digestive conditions.
What can you do initially?
- Avoid lying down immediately after eating.
- Observe foods or situations that trigger symptoms.
- Seek evaluation for persistent, frequent or severe symptoms.
- Do not assume new or unexplained chest pain is heartburn.
🚨 Warning signs
- New or severe chest pressure or pain.
- Chest symptoms with shortness of breath, sweating or pain spreading to the arm, back, neck or jaw.
- Vomiting blood or material resembling coffee grounds.
- Black stool, severe abdominal pain or difficulty swallowing.
If you believe the situation is life-threatening, call 911 in the United States.
