Patients with varicose veins can exercise, but exercise is selective. Because the venous reflux of lower limbs mainly depends on the one-way opening effect of venous valve on the heart, the dynamic effect of calf muscle pump, the beating of heart and the centripetal attraction of negative pressure in chest cavity to surrounding veins. The main purpose of fitness is to strengthen calf muscle strength, enhance vascular tension of lower limbs, and avoid increasing abdominal and thoracic pressure. Swimming is very suitable for patients with varicose veins of lower limbs and can give full play to the role of calf muscle pressure pump. At the same time, when the human body lies flat, it is beneficial for venous blood to return to the heart, but pay attention to the water temperature when swimming. Squatting is also a reasonable exercise for patients with varicose veins. Simple squats can not only exercise muscles, but also benefit joints. It can not only effectively prevent varicose veins and leg cramps, but also promote blood circulation and enhance physical fitness. In addition, cycling, walking and jogging are also good choices, but patients are advised to wear elastic socks. At the same time, avoid activities such as weightlifting, long jump and shot put that cause abdominal pressure to increase.
