Esophagitis is inflammation in the esophagus. Adults who have chronic esophagitis over many years are more likely to develop precancerous changes in the esophagus.
An esophageal stricture happens when your esophagus becomes too narrow. Esophageal strictures can lead to problems with swallowing.
With GERD you might breathe stomach acid into your lungs. The stomach acid can then irritate your throat and lungs, causing respiratory problems, such as
- asthma—a long-lasting disease in your lungs that makes you extra sensitive to things that you’re allergic to
- chest congestion, or extra fluid in your lungs
- a dry, long-lasting cough or a sore throat
- hoarseness—the partial loss of your voice
- laryngitis—the swelling of your voice box that can lead to a short-term loss of your voice
- pneumonia—an infection in one or both of your lungs—that keeps coming back
- wheezing—a high-pitched whistling sound when you breathe
GERD can sometimes cause Barrett’s esophagus. A small number of people with Barrett’s esophagus develop a rare yet often deadly type of cancer of the esophagus.
If you have GERD, talk with your doctor about how to prevent or treat long-term problems.
