What is the GERD?
GERD is a condition of gastric contents reflux which can irritate the lining of esophagus, causing frequent discomfort, acid indigestion and heartburn and may lead to tissue damage. Reflux does not always cause symptoms and may occur occasionally even in healthy people. GERD is a problem only if it creates severe symptoms or complications and requires lifestyle changes or medical treatment.
Causes of GERD
The role of the lower esophageal sphincter is to function as a barrier to gastric contents reflux. Conditions or substances that interfere with the sphincter's ability to function properly can predispose a person to GERD. Pregnancy is the most common predisposing condition. The two-thirds of pregnant women are suffering of heartburn, which usually begins during the first trimester.
