What is gastroesophageal reflux disease (GERD)?

Reflux means that stomach acid and juices flow from the stomach back up into the tube that leads from the throat to the stomach (esophagus). This causes heartburn. When you have heartburn that bothers you often, it is called gastroesophageal reflux disease, or GERD.

Eating too much or bending forward after eating sometimes causes heartburn and a sour taste in the mouth. But having heartburn from time to time doesn't mean that you have GERD. With GERD, the reflux and heartburn last longer and come more often. If this happens to you, be sure to get it treated, because GERD can cause ulcers and damage to your esophagus.

What causes GERD?

Normally when you swallow your food, it travels down the food pipe (esophagus) to a valve that opens to let the food pass into the stomach and then closes. With GERD, the valve doesn't close tightly enough. Stomach acid and juices flow from the stomach and back up (reflux) into the esophagus.

What are the symptoms?

The main symptom of GERD is heartburn. It may feel like a burning, warmth, or pain just behind the breastbone. It is common to have symptoms at night when you're trying to sleep.

If you have pain behind your breastbone, it is important to make sure that it isn't caused by a problem with your heart. The burning sensation caused by GERD usually occurs after you eat. Pain from the heart usually feels like pressure, heaviness, weight, tightness, squeezing, discomfort, or a dull ache. It occurs most often after you are active.

How is GERD diagnosed?

First, your doctor will do a physical exam and ask you questions about your health. You may or may not need further tests. Your doctor may just treat your symptoms by prescribing medicines that reduce or block stomach acid. These include H2 blockers (for example, Pepcid) and proton pump inhibitors (for example, Prilosec). If your heartburn goes away after you take the medicine, your doctor will likely diagnose GERD.
