What Is Acid Reflux Disease?

Font Size

At the entrance to your stomach is a valve, which is a ring of muscle called the lower esophageal sphincter (LES). Normally, the LES closes as soon as food passes through it. If the LES doesn't close all the way or if it opens too often, acid produced by your stomach can move up into your esophagus. This can cause symptoms such as a burning chest pain called heartburn. If acid reflux symptoms happen more than twice a week, you have acid reflux disease, also known as gastroesophageal reflux disease (GERD).

What Causes Acid Reflux Disease?

One common cause of acid reflux disease is a stomach abnormality called a hiatal hernia. This occurs when the upper part of the stomach and LES move above the diaphragm, a muscle that separates your stomach from your chest. Normally, the diaphragm helps keep acid in our stomach. But if you have a hiatal hernia, acid can move up into your esophagus and cause symptoms of acid reflux disease.

These are other common risk factors for acid reflux disease:

  • Eating large meals or lying down right after a meal
  • Being overweight or obese
  • Eating a heavy meal and lying on your back or bending over at the waist
  • Snacking close to bedtime
  • Eating certain foods, such as citrus, tomato, chocolate, mint, garlic, onions, or spicy or fatty foods
  • Drinking certain beverages, such as alcohol, carbonated drinks, coffee, or tea
  • Smoking
  • Being pregnant
  • Taking aspirin, ibuprofen, certain muscle relaxers, or blood pressure medications

 

What Are the Symptoms of Acid Reflux Disease?

Common symptoms of acid reflux are:

  • Heartburn: a burning pain or discomfort that may move from your stomach to your abdomen or chest, or even up into your throat
  • Regurgitation: a sour or bitter-tasting acid backing up into your throat or mouth

Other symptoms of acid reflux disease include:

  • Bloating
  • Bloody or black stools or bloody vomiting
  • Burping
  • Dysphagia -- a narrowing of your esophagus, which creates the sensation of food being stuck in your throat
  • Hiccups that don't let up
  • Nausea
  • Weight loss for no known reason
  • Wheezing, dry cough, hoarseness, or chronic sore throat
