Gastroesophageal reflux disease, hiatal hernia, acid reflux and GERD are different names which relate to a common condition, usually in conjunction with a weakness of the ring of muscle (hiatal hernia) that prevents stomach acid from backwashing up into the esophagus.

GERD often causes cough, severe heartburn, gas and other annoying symptoms.
The condition can be treated with drugs, such as Pepcid AC.

If symptoms persist despite therapy, you should seek out a gastroenterologist, as chronic reflux may lead to a premalignant condition known as Barrett’s esophagus which we discussed yesterday.

The diagnosis of GERD is made during X-rays of the upper gastrointestinal tract or by endoscopy (viewing the esophageal and gastric linings through a fiber-optic tube).
