Digestion/Excretion Disease Acid Reflux

Acid Reflux

What is Acid reflux?

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).

Symptoms of Acid Reflux 

• 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

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.

How's it diagnosed?

• Barium swallow (esophagram) can check for ulcers or a narrowing of the esophagus. You first swallow a solution to help structures show up on an X-ray.
• Esophageal manometry can check the function of the esophagus and lower esophageal sphincter.
• pH monitoring can check for acid in your esophagus. The doctor inserts a device into your esophagus and leaves it in place for 1 to 2 days to measure the amount of acid in your esophagus.
• Endoscopy can check for problems in your esophagus or stomach. This test involves inserting a long, flexible, lighted tube down your throat. First, the doctor will spray the back of your throat with anesthetic and give you a sedative to make you more comfortable.
• A biopsy may be taken during endoscopy to check samples of tissue under a microscope for infection or abnormalities.
