Stomach Muscularis Disorders

The muscularis is the muscle layer of your stomach responsible for moving and mixing food. When there’s a problem with this layer, it can lead to serious issues affecting digestion and comfort. Stomach muscularis disorders occur when the muscles in this layer don’t function properly. This article will help you understand the types, causes, symptoms, diagnostic tests, treatments, and more.

Stomach muscularis disorders involve problems with the muscles in the stomach that control movement and mixing of food. These issues can cause difficulty with digestion, pain, bloating, or even more severe symptoms.

Types of Stomach Muscularis Disorders

1. Gastroparesis: A condition where the stomach muscles don’t work correctly, causing delayed emptying of the stomach.
2. Achalasia: Difficulty in the muscles of the esophagus (tube connecting the throat to the stomach) and stomach, leading to difficulty swallowing.
3. Functional Dyspepsia: A disorder where the stomach muscles don’t contract properly, leading to discomfort, bloating, and indigestion.
4. Pyloric Stenosis: Narrowing of the pylorus (the part connecting the stomach to the small intestine), which can lead to vomiting and inability to digest food properly.
5. Diffuse Esophageal Spasm: Irregular muscle contractions in the esophagus, often causing pain and difficulty swallowing.
6. Zenkers Diverticulum: A condition where a pouch forms at the junction of the esophagus and throat, causing difficulty with food passage.
7. Scleroderma (stomach involvement): A condition where stomach muscles stiffen and fail to contract.
8. Diabetic Gastropathy: Stomach muscle dysfunction caused by diabetes.
9. Post-surgical Delayed Gastric Emptying: Muscular issues following stomach surgery.
10. Myenteric Plexus Disorders: Disorders involving the nerve network that controls stomach muscle contractions.
11. Hypercontractile Peristalsis: Overactive stomach muscle contractions.
12. Hypertrophic Pyloric Stenosis: A condition mostly seen in infants where the muscles around the stomach valve thicken and block food passage.
13. Intestinal Pseudo-obstruction: A disorder that mimics a blockage in the intestines due to muscle or nerve problems in the stomach.
14. Chronic Intestinal Pseudo-obstruction (CIPO): Long-term pseudo-obstruction caused by muscularis issues.
15. Bezoars: Hard lumps that form when stomach muscles can’t grind food properly.
16. Autoimmune Myositis: Inflammation of the stomach muscles due to autoimmune disease.
17. Mesenteric Ischemia: Reduced blood flow to the stomach muscles, leading to dysfunction.
