Why does my lower right abdomen hurt when I run?

Pain in the right lower abdomen is a relatively common physical condition, and pain in the right lower abdomen when running is also a very common situation. There are many reasons for pain in the right lower abdomen when running. It is usually due to improper warm-up or insufficient warm-up, which causes the internal organs to react, which can easily lead to pain in the right lower abdomen. It may also be due to intestinal spasms caused by improper running.

Why does my lower right abdomen hurt when I run?

1. Insufficient warm-up exercises

Inadequate warm-up can cause right lower abdominal pain when running. If you start running immediately without sufficient warm-up exercises, you will increase the exercise intensity before the functions of your internal organs have reached the proper level. This will cause, especially when the myocardial strength is poor, weak pulsation, affected venous blood return, increased pressure in the inferior vena cava, and obstruction of hepatic venous return, thus causing congestion and swelling of the liver and spleen, increasing the tension of the liver and spleen capsules, and resulting in referred pain.

Recommendation: The key to preventing this type of exercise-induced abdominal pain is to do adequate warm-up exercises before exercise to allow the internal organs to adapt.

2. Rectus abdominis spasm

Lower right abdominal pain during running may be caused by rectus abdominis spasm. Rectus abdominis spasm often occurs in the summer when doing strenuous exercises such as running. The loss of a large amount of water and salt, metabolic disorders in the body, and fatigue can cause rectus abdominis spasm pain.

Recommendation: The key to preventing rectus abdominis spasms is to replenish salt water appropriately when sweating during exercise in summer, and local massage of the rectus abdominis and back extension exercises to lengthen the rectus abdominis can relieve abdominal pain.

3. Intestinal spasms

Lower right abdominal pain during running is also considered to be caused by intestinal spasm. When you inhale a lot of cold air while running, coupled with the intense stimulation of running, it will cause sudden intestinal spasm and abdominal pain. It is best to stop running when intestinal spasm occurs.

Recommendation: When running in cold weather, you should be careful not to breathe through your mouth, but through your nose. Also, your daily running exercises should not be too intense, and jogging is recommended.

4. Ovarian cysts

Women who experience right lower abdominal pain while running should also consider whether it is caused by ovarian cysts. Ovarian cyst refers to the symptom of benign tumors growing on one or both sides of a woman's ovaries. It may be painless at ordinary times, but when the cyst gradually grows larger, tenderness, inflammation or strenuous exercise stimulation occurs, it will cause pain in the cyst area.

Recommendation: If you suspect you have ovarian cysts, it is best to go to a regular hospital for an ultrasound examination to confirm the diagnosis, follow the doctor's advice for treatment, and pay attention to a light diet and regular exercise.

5. Kidney stones

Young and middle-aged men who experience right lower abdominal pain while running should also consider whether it is caused by kidney stones. Most patients with kidney stones have no obvious symptoms, but when doing strenuous exercise such as running, kidney stones may fall into the ureter and cause urine blockage and infection in the ureter, which can cause symptoms such as lower back and abdominal cramps, nausea, and bloating.

Recommendation: When the above symptoms occur, you should consider whether you have kidney stones. You can go to the hospital for examination and diagnosis. In your daily diet, you should pay attention to eating less foods that are likely to cause kidney stones, such as tofu, spinach, persimmons, etc.

6. Appendicitis

The right lower abdominal pain during running is probably caused by appendicitis. Appendicitis is more common among young people. It develops rapidly and the clinical symptoms generally include pain in the upper abdomen or Qizhou first, followed by fixed pain in the right lower abdomen. The pain is persistent bloating or dull pain, and may be accompanied by nausea, vomiting, fever and other symptoms.

Recommendation: If the right lower abdominal pain during running is caused by appendicitis, the abdominal pain will be difficult to relieve and the patient will continue to feel pain. In order to prevent the patient from becoming dehydrated, it is recommended to seek medical treatment.

7. When is the best time to run?

(1) Morning run

Advantages: Keep you energetic all day long; Disadvantages: Increase the burden on cardiovascular and cerebrovascular systems, and the air quality is worrying;

Recommendation: Do not exercise outdoors too early and do not eat breakfast before morning jogging.

Many people believe that exercising in the morning can help increase metabolism, making people energetic and full of spirit throughout the day. However, "the body is like a machine. It needs to be warmed up before it can operate. Insufficient warm-up will cause wear of parts." Li Rui, attending physician of the Department of Cardiology at the Guangzhou Military Region General Hospital, said that exercising in the morning will increase the burden on the cardiovascular system, and insufficient warm-up may even lead to the risk of joint injuries.

In addition, during this period of time, there are many pollutants such as smoke, benzene, etc. deposited in the atmosphere on land, and the concentration of carbon dioxide is high. If runners inhale a large amount of it, it will cause harm to their health. Therefore, Li Rui suggested that outdoor fitness should not be done too early, and one should not get up early to exercise on foggy days or in places with poor air quality. Don't eat breakfast before a morning run to prevent gastrointestinal discomfort.

(2) Afternoon run

Advantages: The body is fully warmed up; Disadvantages: It is easy to affect dinner, causing indigestion or gastroenteritis; Recommendation: Do not exercise one and a half hours before meals.

After a day of "warming up", the condition of people's nerves, muscles and joints reaches its peak in the afternoon near dusk, that is, from 4 to 6 o'clock. At this time, exercise can minimize the probability of injury. In addition, the outdoor temperature is moderate, which is very suitable for running.

However, this time period happens to be the busiest time for many office workers. Some people take time out after get off work to go jogging and miss their meals, or eat immediately after exercise. These are very unhealthy and can cause indigestion or gastroenteritis. The correct approach is to not exercise within an hour and a half before a meal, to do light exercises such as walking and Tai Chi half an hour after a meal, and to do moderate-intensity exercises such as jogging after an hour and a half.

(3) Night running

Advantages: good weight loss effect; Disadvantages: vulnerable to cold invasion;

Recommendation: Choose a place with lots of people and plenty of light.

Night running seems to be the best choice for students, white-collar workers and other people who find it difficult to find time to exercise during the day. You sweat less, feel cooler, and won't get tanned. In addition, your hormones respond most strongly to exercise during this time period, which has a better weight-loss effect.
