Lower Esophageal Sphincter Atrophy

The lower esophageal sphincter (LES) is a muscle located at the end of the esophagus where it meets the stomach. Its primary function is to prevent stomach acids from flowing back into the esophagus. Atrophy of the LES refers to the weakening or thinning of this muscle, which can lead to various health issues. This guide covers the types, causes, symptoms, diagnostic tests, treatments, and more related to LES atrophy.

Lower esophageal sphincter atrophy is a condition where the LES becomes weakened or thinned out, impairing its ability to function properly. This can lead to gastroesophageal reflux disease (GERD) and other related issues.

Types of Lower Esophageal Sphincter Atrophy

1. Functional Atrophy: Where the LES muscle is weakened but not structurally damaged.
2. Structural Atrophy: Involves physical thinning or degeneration of the LES muscle tissue.
3. Secondary Atrophy: Resulting from other conditions or diseases affecting the LES.

Causes of Lower Esophageal Sphincter Atrophy

1. Aging: Natural weakening of muscles with age.
2. Chronic Acid Reflux: Prolonged exposure to stomach acids can damage the LES.
3. Obesity: Excess weight increases abdominal pressure, affecting the LES.
4. Hiatal Hernia: A condition where part of the stomach pushes up through the diaphragm, affecting the LES.
5. Smoking: Harms the LES and increases acid reflux.
6. Alcohol Consumption: Can relax the LES and increase reflux.
7. Caffeine Intake: Can weaken the LES.
8. Certain Medications: Such as antihistamines and blood pressure drugs.
