Your description of your symptoms may be all a doctor requires to diagnose heartburn, but sometimes additional testing may be necessary. The esophagus can be viewed through an endoscope, a long, thin, flexible tube inserted through the mouth, or by X-ray.
Sometimes, your doctor may recommend a 24-hour esophageal pH probe study, especially if you have unusual symptoms, such as throat or chest or abdominal pain, coughing, or asthma-like symptoms. In this test, a long, narrow, flexible tube is inserted through the nose down into the esophagus and a probe is left there for 24 hours. This probe detects acid levels to determine if it correlates with your symptoms. A newer technique (called Bravo) measures 24-hour acid; it is done using wireless pH sensors, which eliminates the need for a tube insertion. To detect if your heart is the cause of your symptoms, an electrocardiogram (ECG), a recording of the heart's electrical activity, may be taken.
If you take any prescription or over-the-counter medications, you may have side effects. And one of them can be heartburn -- that burning in your chest or throat that happens when acid flows up from your stomach.
Don’t assume you’ll just have to live with it.
Make a list of all the medications you take, and ask your doctor if one of them may be causing your heartburn. Your doctor can change your medication, says Walter Coyle, MD, at Scripps Clinic Torrey Pines in California.
