SATURDAY, Jan. 11, 2003 (HealthDayNews) -- It's called heartburn, but your heart has nothing to do with it.
The condition is actually caused by gastroesophageal reflux disease (GERD). The term gastroesophageal refers to the stomach and esophagus.
Reflux means to flow back or return. So, gastroesophageal reflux is simply the return of the stomach's contents back up into the esophagus. GERD typically affects the lower esophageal sphincter, the muscle connecting the esophagus with the stomach. Many people, including pregnant women, suffer from heartburn caused by GERD.
Physicians also think some people suffer from GERD and associated heartburn due to a condition called hiatal hernia. That happens when the upper part of the stomach moves up into the chest through a small opening in the diaphragm, the muscle separating the stomach from the chest.
Recent studies show the opening in the diaphragm acts as an additional sphincter around the lower end of the esophagus. The research also shows a hiatal hernia can trap acid and other digestive contents above this opening. These substances then flow easily back into the esophagus, causing that painful, burning sensation in the middle of the chest known as heartburn.
Dietary and lifestyle choices may contribute to GERD. Certain foods and beverages, including chocolate, peppermint, fried or fatty foods, coffee or alcoholic beverages may cause reflux and heartburn.
Obesity is also associated with these symptoms. In most cases, heartburn can be relieved through diet and lifestyle changes. However, some people may require medication or surgery.
