Gastroesophageal reflux disease (GERD) is a condition in
which the esophagus becomes irritated or inflamed because of acid backing up
from the stomach. The esophagus or food pipe is the tube stretching from the
throat to the stomach. When food is swallowed, it travels down the esophagus.
The stomach produces hydrochloric acid after a meal to
aid in the digestion of food.
The inner lining of the stomach resists corrosion by
this acid. The cells that line the stomach secrete large amounts of protective
The lining of the esophagus does not share these
resistant features and stomach acid can damage it.
The esophagus lies just behind the heart, so the term heartburn was coined
to describe the sensation of acid burning the esophagus.
Normally, a ring of muscle at the bottom of the
esophagus, called the lower esophageal sphincter, prevents reflux (or backing up) of acid.
This sphincter relaxes during swallowing to allow
food to pass. It then tightens to prevent flow in the opposite direction.
With GERD, however, the sphincter relaxes between swallows, allowing stomach contents and corrosive acid to well up and damage the lining of the esophagus.
25% to 40% of the adult population of the United States to some degree at some
point. About 10% of adults experience GERD weekly or daily. Not just adults are affected; even infants and children can have GERD.
Acid Reflux (GERD) Causes
No one knows the exact cause of gastroesophageal reflux. The following are contributing factors that weaken or relax the lower esophageal sphincter, making reflux worse:
Lifestyle: Use of alcohol or
cigarettes, obesity, poor
The eMedicineHealth doctors ask about Acid Reflux (GERD):
GERD - Proton Pump Inhibitors
Heartburn symptoms caused by GERD are usually relieved by drugs called proton pump inhibitors (PPIs), such as Prilosec, Prevacid, Aciphex, Protonix, Nexium, Zegerid; however, sometimes they do not work well. Can you please describe your GERD symptoms that did not improve on PPIs? Did you find other treatments effective?
The medical treatment options are used to prevent complications and reduce morbidity associated with GERD, and they include antacids, H2 receptor antagonists, proton pump inhibitors, coating, and promotility agents. In addition to medications, the following lifestyle modifications below are recommended:
Instead of eating large meals, eat small meals more frequently.
Avoid caffeine-containing foods and beverages (for example, coffee, tea, soft drinks, chocolate)...
