Step-by-step explanation:
Mr. Jankowski describes that uncomfortable feeling as heartburn. The medical term for this condition is gastroesophageal reflux disease (GERD). Heartburn is a symptom of GERD and occurs when stomach acid backs up into the esophagus, causing a painful burning sensation in the chest. Although commonly associated with indigestion or dyspepsia, heartburn can be a sign of a more serious condition such as GERD or even a peptic ulcer. Lifestyle changes and medications can often help manage the symptoms of heartburn and reduce the risk of damage to the esophagus.
