Most people experience acid reflux now and then. Gastroesophageal reflux disease is a condition in which stomach acid repeatedly flows back in the opposite direction from the stomach into the food pipe. It’s often called GERD for short. This backflow can irritate the lining of the food pipe and the throat.
Symptoms
A burning sensation in the chest, often called heartburn is the most common symptom. Heartburn usually happens after eating and might be worse at night or while lying down. Regurgitation of food can happen after meals and while lying down. Back flow of acid can sometimes reach the throat and cause throat pain or discomfort. If you have nighttime acid reflux, you also might experience cough.
Investigation
The severity of reflux can be assessed by Endoscopy examination. This examination takes about 2-3 minutes and performed after spraying the throat with Local anaesthetic solution. It can be done under sedation for anxious patients. This examination is always performed in empty stomach. Endoscopy can detect the severity of damage to the inner lining of food pipe. It can also check for laxity of the valve between food pipe and stomach. Hiatus hernia which can be the cause of reflux in some patients can also be detected on endoscopy
Diagnostic Tests
Reflux disease diagnosis typically involves:
- History and Symptoms Discussion: Identifying triggers and patterns.
- Endoscopy: Visualizing the esophagus for inflammation or damage.
- pH Monitoring: Measuring acid levels in the esophagus.
- Barium Swallow X-rays: Detecting structural abnormalities.
- Manometry: Assessing esophageal muscle function.
These tests help confirm reflux disease, identify complications, and guide treatment.
