Abdominal fluttering or spasms can be caused by pregnancy, muscle fatigue, stress, excess gas or acid in the gastrointestinal tract, or bowel disorders. Abdominal fluttering is described as a vibration or fluttering sensation in the abdomen, according to Steady Health.
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. The term "spastic colon" is used to described a frequent symptom of irritable bowel syndrome (IBS), which results from bowel contractions, according to the Mayo Clinic. Patients with spastic colon should discuss treatment options with a doctor.
Most causes of abdominal fluttering are not serious health risks, according to Health Grades, but they require professional diagnosis. This is especially true if the fluttering is accompanied by pain, nausea, fever or respiratory problems. In some cases, serious conditions like diverticulitis or bowel obstructions can cause abdominal fluttering.
