Why Do I Have A Sour Taste In My Mouth?

A sour taste in the mouth can be a sign of several problems. GERD, or gastroesophageal reflux disease, is caused by changes in the digestive system or organs. Although a doctor can help you diagnose the underlying cause, a simple diet change can improve your symptoms. A visit to the dentist can also help you determine the cause.

If you have a sour taste in your mouth, it’s likely a GERD symptom, an acid reflux disease. During normal digestion, gastric acid flows up the esophagus, causing a burning sensation in the chest that can be mistaken for a heart attack. Therefore, if you notice a sour taste in your mouth after eating, you should seek a doctor’s diagnosis. A doctor can examine your esophagus and your stomach and prescribe anti-acids to neutralize the acid in your mouth if necessary.

In these cases, the sour or bitter taste may also be present in the mouth. Symptoms of GERD may also co-occur with heartburn. Having a sour or a bad taste in the mouth could signify a medical condition known as dysgeusia.

This is usually a GERD indicator when a person has a sour or bitter-tasting mouth.
