Stomach Muscularis Injury

Stomach muscularis injury refers to damage to the muscular layer (muscularis) of the stomach. This layer plays a crucial role in churning and mixing food, helping in digestion. When injured, the stomach’s ability to function properly is compromised, which can lead to a range of digestive problems.

Types of Stomach Muscularis Injury

1. Strain or Tear: Overstretching of the stomach muscles, often due to forceful vomiting or intense physical activity.
2. Ischemic Injury: Damage caused by a lack of blood flow to the stomach muscles, which can result from conditions like atherosclerosis or low blood pressure.
3. Infectious Injury: Infection in the stomach muscles due to bacteria or viruses.
4. Traumatic Injury: Physical trauma to the stomach, such as blunt force from an accident or surgery.
5. Inflammatory Injury: Inflammation due to conditions like gastritis, which can affect the stomach muscles.
6. Degenerative Changes: Age-related wear and tear on the stomach muscles.
7. Autoimmune Injury: Conditions like Crohn’s disease can cause the immune system to attack the stomach’s muscular layer.
8. Drug-Induced Injury: Medications, particularly NSAIDs, can cause damage to the stomach lining and muscles.
9. Ulcer-related Damage: When stomach ulcers penetrate deeper into the stomach’s layers, they can injure the muscularis.
10. Neoplastic Injury: Tumors affecting the stomach muscle layers.
