The stomach circular muscularis layer is a part of the stomach’s muscular wall, responsible for squeezing and mixing food to help digestion. A spasm in this layer occurs when the muscles contract involuntarily and abnormally. This spasm can lead to discomfort, pain, and other digestive issues, affecting the normal process of moving food through the stomach.
Types of Stomach Muscle Spasms
There are different types of muscle spasms in the stomach, based on the location and nature of the spasm:
- Acute spasms: Sudden and short-lived, but intense.
- Chronic spasms: Recur over a long period.
- Local spasms: Affect a specific part of the stomach.
- Diffuse spasms: Affect a larger area or the entire stomach.
- Primary spasms: Occur without any underlying disease.
- Secondary spasms: Caused by underlying medical conditions.
- Isolated muscle spasms: Affect only the circular muscle layer.
- Peristaltic spasms: Disrupt normal digestive movements, leading to pain and discomfort.
- Hypertrophic spasms: Due to thickened muscle, often seen in chronic conditions.
- Functional spasms: Occur without any structural abnormalities.
- Hypertonic spasms: Excessive muscle tension and prolonged contractions.
- Esophagogastric junction spasms: Affect the region where the esophagus meets the stomach.
- Diaphragmatic spasms: Affect muscles near the diaphragm, creating pressure on the stomach.
- Pyloric spasms: Affect the valve controlling the passage from the stomach to the small intestine.
- Reflex spasms: Triggered by nerve reflexes due to irritation or stress.
- Stress-induced spasms: Linked to emotional stress or anxiety.
- Post-operative spasms: May occur after abdominal surgery.
