GERD signs and symptoms include:
- A burning sensation in your chest (heartburn), sometimes spreading to your throat, along with a sour taste in your mouth
- Chest pain
- Difficulty swallowing (dysphagia)
- Dry cough
- Hoarseness or sore throat
- Regurgitation of food or sour liquid (acid reflux)
- Sensation of a lump in your throat
When to see a doctor
Seek immediate medical attention if you experience chest pain, especially if you have other signs and symptoms, such as shortness of breath or jaw or arm pain. These may be signs and symptoms of a heart attack.
Make an appointment with your doctor if you experience severe or frequent GERD symptoms. If you take over-the-counter medications for heartburn more than twice a week, see your doctor.
GERD is caused by frequent acid reflux — the backup of stomach acid or bile into the esophagus.
When you swallow, the lower esophageal sphincter — a circular band of muscle around the bottom part of your esophagus — relaxes to allow food and liquid to flow down into your stomach. Then it closes again.
However, if this valve relaxes abnormally or weakens, stomach acid can flow back up into your esophagus, causing frequent heartburn. Sometimes this can disrupt your daily life.
This constant backwash of acid can irritate the lining of your esophagus, causing it to become inflamed (esophagitis). Over time, the inflammation can wear away the esophageal lining, causing complications such as bleeding, esophageal narrowing or Barrett's esophagus (a precancerous condition).
Conditions that can increase your risk of GERD include:
- Bulging of top of stomach up into the diaphragm (hiatal hernia)
- Dry mouth
- Delayed stomach emptying
- Connective tissue disorders, such as scleroderma
Over time, chronic inflammation in your esophagus can lead to complications, including:
- Narrowing of the esophagus (esophageal stricture). Damage to cells in the lower esophagus from acid exposure leads to formation of scar tissue. The scar tissue narrows the food pathway, causing difficulty swallowing.
- An open sore in the esophagus (esophageal ulcer). Stomach acid can severely erode tissues in the esophagus, causing an open sore to form. The esophageal ulcer may bleed, cause pain and make swallowing difficult.
- Precancerous changes to the esophagus (Barrett's esophagus). In Barrett's esophagus, the tissue lining the lower esophagus changes. These changes are associated with an increased risk of esophageal cancer. The risk of cancer is low, but your doctor will likely recommend regular endoscopy exams to look for early warning signs of esophageal cancer.
