what is heartburn

Heartburn is a common symptom of acid reflux, also known as gastroesophageal reflux disease (GERD). It’s a burning sensation in the chest, usually behind the breastbone, that can radiate up to the neck and throat.

Heartburn occurs when stomach acid flows back up into the esophagus, causing irritation and discomfort. This can happen when:

1. The lower esophageal sphincter (LES) doesn’t close properly, allowing stomach acid to flow back up.
2. The stomach produces too much acid.
3. The esophagus is irritated or inflamed.

Common triggers for heartburn include:

– Eating large or heavy meals
– Lying down after eating
– Consuming citrus fruits, tomatoes, chocolate, spicy foods, or fatty foods
– Drinking caffeine, alcohol, or carbonated beverages
– Smoking
– Wearing tight clothing

Symptoms of heartburn can vary from person to person but may include:

– Burning sensation in the chest
– Regurgitation of food or sour liquid
– Difficulty swallowing
– Coughing or wheezing
– Bitter or sour taste in the mouth

If you experience frequent or severe heartburn, it’s essential to consult with a healthcare professional to rule out any underlying conditions that may require medical attention.
