What is Heartburn Or Acidity

 Acid reflux happens when contents from your stomach move back up into your esophagus. This action is also called acid regurgitation or gastroesophageal reflux. If you have symptoms of acid reflux more than twice a week, you might have a condition known as gastroesophageal reflux disease (GERD).

The most common cause is food that's acidic or high in fat—like citrus fruits, tomatoes, onions, chocolate, coffee, cheese, and peppermint. Spicy foods or large meals can also be the root of distress. Other sources of heartburn include aspirin or ibuprofen, as well as some sedatives and blood pressure medications.

Fatty foods, large portions, and late-night meals are the top three triggers that affect many people with heartburn

Heartburn happens because stomach acid becomes backed up in the esophagus, which moves food from your mouth to your stomach. The burning sensation is usually the result of stomach acid leaking up into the esophagus through a flaw in a valve known as the lower esophageal sphincter (LES), which connects the esophagus and the stomach. When the LES doesn't tighten properly or becomes weakened, stomach acid can flow back into the esophagus, causing a burning feeling.
