Acid reflux occurs when stomach acid rises into the esophagus. It is commonly called heartburn, which is the burning sensation that it can cause in the chest or stomach. In its more serious form, it is called GERD, or gastroesophageal reflux disease.
Significance
Acid reflux takes place when the lower esophageal sphincter, which is a valve between the esophagus and the stomach, opens at incorrect times and allows acid to enter the esophagus.
Symptoms
The most common symptoms of acid reflux are heartburn and chest discomfort. Other symptoms may include a sore throat, hoarseness, difficulty swallowing and asthma.
Causes
Acid reflux can be caused or exacerbated by pregnancy, eating large meals, laying down after eating, obesity and smoking. Certain foods, such as citrus foods or coffee, aggravate symptoms in some people.
Lifestyle Changes
Lifestyle changes that may reduce or eliminate acid reflux include eating smaller meals, losing weight if obese, avoiding trigger foods and quitting smoking. Wearing loose clothing and remaining upright after eating can also help you avoid heartburn.
Medical Treatment
Several medications are available to treat acid reflux. These include over-the-counter and prescription antacids, acid suppressants and proton pump inhibitors.
