The upper esophageal sphincter (UES) is a ring-like muscle at the top of the esophagus that controls the entry of food and liquid into the esophagus from the throat and prevents backflow. When the UES doesn’t function properly, it can cause a range of issues. This guide will cover the types, causes, symptoms, diagnostic tests, treatments, and more related to upper esophageal sphincter dysfunction.
Types of Upper Esophageal Sphincter Dysfunction
- Achalasia: A condition where the UES fails to relax properly, causing difficulty swallowing.
- Cricopharyngeal Achalasia: Similar to achalasia but specifically affects the cricopharyngeal muscle, part of the UES.
- Hypertonic UES: When the UES remains too tight, making it hard to swallow.
- Hypotonic UES: When the UES is too relaxed, leading to problems with holding back food or liquids.
- UES Obstruction: Any blockage that prevents the normal functioning of the UES.
- UES Spasm: Irregular contractions of the UES that cause pain or difficulty swallowing.
- UES Reflux: Backflow of stomach contents into the throat due to improper UES function.
