Stomach throbbing without pain may be caused by physiological phenomena, mental factors, stomach cramps, chronic gastritis and other reasons. 1. Physiological phenomenon: the abdominal aorta is at the back of the stomach, and people who are thin are more likely to feel the abdominal aorta throbbing, mistaking it for stomach throbbing, and the rhythm of the throbbing is the same as the heart rate. 2. Mental factors: mental tension, anxiety and depression can lead to sensory dysfunction, so feel the stomach beating. 3. Stomach cramp: diet is not regular, often eat food that stimulates the gastric mucosa, or autonomic dysfunction, resulting in spasm and contraction of the stomach tissue and muscles, causing the stomach to jump. 4. Chronic gastritis: Inflammation of the gastric mucosa exists, the ability to digest food decreases, and eating too much can easily cause gastric dilatation and lead to stomach throbbing, accompanied by acid reflux, nausea and other symptoms. If self-regulation can not be relieved, it is recommended to consult a doctor in a timely manner, and follow the doctor’s instructions for treatment, so as to avoid delaying the condition.
