Hello,
This may be due to peristaltic movements of the food in the intestines or due to muscle
cramps of
abdomen.
Frequent abdominal muscle cramps are seen in prolonged exercise, stress and anxiety, anemia, dehydration and deficiency of sodium, potassium, magnesium, and calcium and in serious disorders like myotonia, vascular disorders and neurodegenerative diseases.
Are you having normal menstrual periods or do you have any signs of pregnancy?
