What Are Some of the Causes of Flutters in the Stomach?

A fluttering sensation in the stomach or lower abdomen may be an early sign of pregnancy, according to SteadyHealth. Fluttering in the stomach could also be the result of an imbalance of electrolytes, muscle fatigue or hyperactivity of the central nervous system.

Increased levels of gas or acid within the digestive system can trigger fluttering in the stomach due to stimulation of the abdomen muscles, explains SteadyHealth. Certain foods that are fried, spicy or sugary as well as dehydration from lack of water or activity can cause fluttering sensations.

Fluttering sensations commonly occur when people are stressed, fearful or anxious, adds SteadyHealth. The brain releases stress hormones that can cause the central nervous system to trigger fluttering within the abdominal muscles.

Stomach fluttering that stems from anxiety and stress can be severe, moderate or slight and typically occurs in waves, according to the Anxiety Centre. Patients experience fluttering due to stress and anxiety at unexpected moments, and the fluttering can correspond with meals, occurring a few hours after eating, right before a meal or immediately after consuming food.

Pregnant women commonly experience stomach fluttering approximately six to 12 days following ovulation, notes SteadyHealth. The twinges or fluttering often occur before women realize they are pregnant and prompt the need for a pregnancy test or medical evaluation.
