This is a question that had been rolling over in my mind since I was first diagnosed with GERD a couple weeks ago. I went searching for the answer and found the following information:

What's the Difference Between Acid Reflux and GERD?

Q: Is there a difference between acid reflux and gastroesophageal reflux disease (GERD)? I have been reading about GERD, and the term "acid reflux" comes up a lot. Are they the same thing?

A: Acid reflux simply means that acid made by your stomach's cells backs up through the lower esophageal junction (where your esophagus and stomach meet). At low levels, acid reflux is a normal part of digestion and movement along the gastrointestinal tract. In normal patients, acid reflux can cause symptoms such as heartburn, but it is not considered to be a disease. Avoiding foods that trigger acid reflux, such as fatty foods, coffee, chocolate, etc, will help relieve any symptoms it causes.

GERD, on the other hand, is characterized by an abnormal frequency or amount of reflux. It can result in heartburn, hoarseness, chest pain, and, rarely, asthma, and may be associated with Barrett's esophagus and esophageal cancer.

The bottom line: Acid reflux is the backing up of stomach acid, while GERD is a disease state of which acid reflux is part.
