What causes pain in the left lower abdomen when running

Running is a sport that many people like, because it is relatively simple, does not require exercise equipment, and can be done anytime and anywhere. If you experience pain in the lower left abdomen while running, it may be a gastrointestinal problem, so you should pay attention to this.

main reason:

In the early morning, people of all ages and genders run, and can be seen by the river, in parks, and on the streets. There are often cases of people seeking medical treatment due to abdominal pain during or after running, especially primary and secondary school students who have to stop exercising due to abdominal pain during physical education classes. Doctors have summarized the causes of abdominal pain caused by running.

Right upper abdominal pain: This is mostly due to lack of exercise. People who lack exercise require more oxygen during exercise than well-trained athletes, so they breathe more rapidly. Under normal circumstances, the negative pressure in the chest cavity increases when inhaling, which is beneficial to the blood return in the hepatic vein and other places. When breathing is rapid, the negative pressure in the chest cavity decreases, and the blood return to the liver is blocked, resulting in liver congestion and causing liver pain.

Gastrointestinal spasm: running on an empty stomach or after a meal, eating too much or drinking too much before exercise (especially too much cold drinks) can all cause gastrointestinal dysfunction, resulting in spasm and abdominal pain; eating too fast before exercise; eating too much or eating food that is difficult to digest, such as beans, potatoes, milk, pasta, etc., can cause abdominal distension due to excessive gas production. In addition, due to strenuous exercise, the abdominal pressure increases, and the peritoneum is stretched, causing abdominal pain. At this time, cold abdomen or stool accumulation, ascaris stimulation, etc. can all cause intestinal spasm and abdominal pain.

Rectus abdominis spasm: When doing strenuous exercise in the summer, the body loses salt and water due to excessive sweating, and failure to replenish water and electrolyte metabolism causes disorders. In addition, fatigue can easily lead to rectus abdominis spasm. This type of abdominal pain often occurs in the later stages of exercise.

Chronic abdominal diseases: Patients with chronic hepatitis, cholecystitis, gastric ulcer or chronic appendicitis may experience pain when participating in strenuous exercise due to the stimulation of pulling, vibration and other factors on the affected area. The pain is usually at the site of the lesion.
