what causes fluttering
Pregnancy is one common cause of abdominal fluttering. It is not a cause for alarm, but it is important to verify the pregnancy with a physician. If the patient is not pregnant, she should explore other possible culprits with a doctor. Fatigue and stress can also cause abdominal fluttering. The muscles in the abdomen spasm because of tension in the body, which produces a fluttering sensation. Excess gas or acid in the gastrointestinal tract are potential causes as well. Bowel disorders are a common cause of abdominal fluttering.
