GERD

Gastroesophageal reflux disease (GERD) is a chronic digestive disease that occurs when stomach acid or, occasionally, bile flows back (refluxes) into your food pipe (esophagus). The backwash of acid irritates the lining of your esophagus and causes GERD signs and symptoms.

Signs and symptoms of GERD include acid reflux and heartburn. Both are common digestive conditions that most people experience from time to time. When these signs and symptoms occur more than twice each week or interfere with your daily life, doctors term this GERD.

Most people can manage the discomfort of heartburn with lifestyle changes and over-the-counter medications. But for people with GERD, these remedies may offer only temporary relief. People with GERD may need stronger medications, even surgery, to reduce symptoms.

GERD signs and symptoms include:

• A burning sensation in your chest (heartburn), sometimes spreading to the 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 the throat

When to see a doctor
Seek immediate medical attention if you experience chest pain, especially when accompanied by 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 turn to over-the-counter medications for heartburn more than twice per 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 and disrupting 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 erode the esophagus, causing complications such as bleeding or breathing problems.
