It’s easy to confuse acid reflux and GERD (gastroesophageal reflux disease). They are both common conditions that often cause heartburn, a burning feeling in the chest, and a sour taste in the back of the throat or mouth. But although they are similar, there’s one big difference. While acid reflux doesn’t typically require treatment, you will want to see your doctor if you think you have GERD. The ABCs of Acid Reflux Acid reflux is also called gastroesophageal reflux, or GER. It happens when the contents of the stomach move back into the esophagus, the tube that leads from the mouth to the stomach. The most common symptom is heartburn. Most people have acid reflux at one time or another. You can help control acid reflux with the following tips: Don’t eat for about 2 to 3 hours before bedtime. Don’t eat too much in one sitting. Lose weight if you are overweight. Skip foods and drinks that can cause acid reflux. These include alcohol, coffee, chocolate, greasy or spicy foods, peppermint, and tomato products like spaghetti sauce. Don’t smoke. Try using antacids like Alka-Seltzer, Mylanta and Rolaids. If you have acid reflux more than twice a week for a couple of weeks, you could have GERD. When It’s GERD GERD is a more serious type of acid reflux. It occurs when the valve between the esophagus and the stomach is weak or does not work correctly. In some cases, other problems with the digestive system, such as hiatal hernias, can also cause GERD. There are some factors that increase your risk for developing GERD. These include: Being overweight Pregnancy Smoking or inhaling secondhand smoke Taking certain medicines, such as antidepressants, antihistamines, asthma medication, pain relievers, and sedatives Symptoms of GERD The most common symptom of GERD is heartburn. But some people with GERD never have heartburn. GERD can also cause the following symptoms: Asthma Bad breath or tooth decay Chronic dry cough Hoarseness or a sore throat Nausea Pain in the chest or upper abdomen Pain with swallowing or trouble swallowing Recurring pneumonia Vomiting If you think you may have GERD, see your doctor. He or she may suggest tests to see whether GERD is causing your symptoms. Left untreated, GERD can lead to serious complications, such as inflammation in the esophagus, narrowing of the esophagus, and respiratory problems.
