Gastroesophageal Reflux Disease (GERD)

A chronic condition where stomach acid flows back into the esophagus, causing symptoms like heartburn, regurgitation, and discomfort. It can lead to complications if left untreated.

 

Esophagus

The muscular tube connecting the throat (pharynx) with the stomach. It transports food and liquids from the mouth to the stomach.

 

Heartburn

A burning sensation in the chest, often accompanied by a sour taste in the mouth, caused by stomach acid backing up into the esophagus.

 

Acid Reflux

The backward flow of stomach acid into the esophagus, resulting in irritation and inflammation of the esophageal lining.

 

GERD Symptoms

Common symptoms include heartburn, regurgitation of sour liquid or food, difficulty swallowing, chest pain, and persistent cough.

 

Hiatal Hernia

A condition where a portion of the stomach protrudes into the chest cavity through the diaphragm, which can contribute to GERD by weakening the lower esophageal sphincter.

 

Lower Esophageal Sphincter (LES)

A muscular valve at the lower end of the esophagus that opens to allow food and liquid into the stomach and closes to prevent stomach contents from flowing back into the esophagus.

 

Proton Pump Inhibitors (PPIs)

Medications that reduce the production of stomach acid by blocking the enzyme in the stomach wall that produces acid. They are commonly prescribed to manage GERD symptoms.

 

Lifestyle Modifications

Dietary and behavioral changes such as avoiding trigger foods, maintaining a healthy weight, elevating the head of the bed, and quitting smoking can help alleviate GERD symptoms.

 

Barrett’s Esophagus

A complication of GERD where the normal tissue lining the esophagus is replaced by abnormal cells, increasing the risk of esophageal cancer. Regular monitoring is essential for early detection and management.
