Stomach Muscularis Externa Dysfunction

The muscularis externa is a layer of muscle in the stomach that plays an essential role in digestion by contracting to help mix and move food through the digestive system. When there is a problem with this layer, it can lead to various digestive issues, commonly referred to as stomach muscularis externa dysfunction.

This guide will walk you through everything you need to know about stomach muscularis externa dysfunction, including its types, causes, symptoms, diagnostic tests, non-pharmacological treatments, medications, surgeries, prevention, and when to see a doctor. Our goal is to explain this complex topic in plain and simple language, making it easy for you to understand.

Types of Stomach Muscularis Externa Dysfunction

There are several types of problems that can affect the muscularis externa:

1. Gastroparesis – A condition where the stomach muscles don’t work properly, leading to slow movement of food.
2. Hypertrophic Pyloric Stenosis – Thickening of the muscles between the stomach and small intestine, blocking food passage.
3. Diffuse Esophageal Spasm – When the muscles in the esophagus (connected to the stomach) spasm and cause swallowing difficulties.
4. Functional Dyspepsia – When the stomach muscles do not contract efficiently, causing pain and indigestion.
5. Pyloric Dysfunction – Issues with the muscles that control the opening between the stomach and the small intestine.
6. Esophageal Achalasia – A rare disorder where the lower esophageal muscles fail to relax, causing swallowing difficulties.
7. Post-surgical Dysmotility – Dysfunction caused by surgery in the stomach area, leading to abnormal muscle function.
8. Chronic Intestinal Pseudo-Obstruction – A rare disorder where the intestinal muscles act as though there is a blockage, but there isn’t.
9. Myenteric Plexus Damage – The nerve cells controlling the muscularis externa are damaged, leading to dysfunctional muscle movement.
10. Hypercontractile Esophagus – An excessive contraction of the muscles of the esophagus, making swallowing painful.

Causes of Stomach Muscularis Externa Dysfunction
