Lower Esophageal Sphincter Injuries

The Lower Esophageal Sphincter (LES) is a muscle at the junction of the esophagus and stomach that acts as a valve, preventing stomach contents from flowing back into the esophagus. LES injuries refer to damage or dysfunction in this muscle, leading to conditions such as acid reflux, heartburn, or even more severe gastroesophageal reflux disease (GERD). This comprehensive article will explore the types, causes, symptoms, diagnostic tests, treatments, medications, surgeries, prevention, and when to see a doctor regarding LES injury.

Types of Lower Esophageal Sphincter Injuries

1. LES Dysfunction – The muscle becomes weak or relaxes too much, allowing stomach acid to flow into the esophagus.
2. LES Hypertension – The sphincter becomes abnormally tight, causing difficulty in food passage from the esophagus to the stomach.
3. LES Hypotension – The sphincter is overly relaxed or underactive, causing reflux symptoms.
4. LES Tear – Physical injury or trauma to the sphincter muscle can result in a tear.
5. LES Relaxation Abnormality – Involuntary relaxation of the LES, leading to acid reflux.
6. LES Strain – Overstretching of the muscle fibers can lead to strain.
7. LES Sprain – Overextension or overuse leads to sprain-like symptoms in the sphincter.
8. LES Scar Tissue – Scar formation can make the LES less flexible or functional.
9. LES Inflammation – Inflammation in the esophageal area can affect LES functioning.
10. LES Atrophy – Weakening or degeneration of the muscle tissue over time.
11. LES Fibrosis – Fibrous tissue formation can make the sphincter less elastic.
12. LES Erosion – Acidic exposure can wear down the LES tissue.
13. LES Infection – Infections, such as bacterial or viral, can damage the LES.
14. LES Spasms – The sphincter undergoes involuntary contractions, disrupting its normal function.
15. Post-surgical LES Injury – After surgeries such as fundoplication, the LES may be compromised.
16. LES Neuropathy – Damage to the nerves controlling the LES can impair its function.
17. LES Diverticulum – Abnormal outpouchings near the sphincter can weaken the muscle.
18. LES Degeneration – Gradual deterioration of LES function due to aging or disease.
19. Congenital LES Dysfunction – Present at birth, where the sphincter does not work properly.
20. Chemical Burn LES Injury – Damage from ingestion of corrosive substances.

Causes of Lower Esophageal Sphincter Injuries

1. Chronic Acid Reflux (GERD) – Continuous exposure to stomach acid weakens the LES.
2. Hiatal Hernia – The stomach pushes through the diaphragm, impairing LES function.
