Why does my stomach hurt when I run?

Stomachache generally refers to stomachache. Stomachache after running may be related to eating too much, excessive exercise, improper breathing, etc.

1. Eating

too much or too fast may fill the stomach with food. When running, it may cause food to repeatedly hit the gastric mucosa in the stomach, causing stomachache.

2. Excessive exercise

may cause blood flow to the muscles, reducing blood flow to the gastrointestinal tract, causing gastrointestinal ischemia, resulting in stomach cramps.

3.

Improper breathing should be used when running. If breathing is improper, it may cause diaphragm cramps, causing stomach compression, causing stomachache.
