The stomach beating like a heart can be considered a stomach cramp or a physical phenomenon when you are thin. The stomach does not beat. When the stomach cramps the stomach muscles twitch and show a strong contraction, this state is perceived by the patient as beating. Patients with stomach cramps often present with epigastric pain and vomiting. Stomach disorders such as gastritis, gastric ulcer, and cold in the stomach are triggering factors for stomach muscle twitching. When the body is thin, the stomach is closer to the heart and the abdominal aorta, and it is possible that the heart beat or the abdominal aorta beat is sensed through the stomach, and the patient realizes that the stomach is beating, but it is actually the heart beat or the abdominal aorta beat, which is a physiological phenomenon. When the patient’s symptoms of stomach cramps are more obvious, they should go to the hospital in time to seek treatment for the original disease, and use medication under the guidance of the doctor.
