Butterflies in the stomach is a medical condition characterized by the physical sensation of a “fluttery” or “tickling” (hence butterflies) feeling in the stomach. This sensation can be a physical sensation related to the body’s fight or flight response or it can be an ineffable experience related to the psychology of love.
Some believe that this is caused by the release of epinephrine, or adrenaline when one is nervous, pulling blood away from the stomach and sending it to the muscles. This reduced blood flow, in turn, causes the stomach to temporarily shut down, and possibly the reason for reduced appetite during love sickness.
