Running stomach pain may be related to the following factors: First, the fork, if you do not do a good warm-up exercise before running, the body's motor system will be stimulated during running, resulting in faster breathing and heartbeat frequency, resulting in the phenomenon of fork. Second, improper exercise, if running too fast, the body's oxygen demand significantly increased, may lead to abdominal muscle hypoxia, muscle spasms and other conditions, resulting in pain. III. The patient did not exercise for a long time. After re-exercise, the abdominal organs could not adapt to the vibration and traction in time during running, and pain and other discomfort symptoms appeared.
