1. Obese people should lose weight. Obesity is not the direct cause, but excessive leg pressure may cause poor venous return and aggravate venous dilatation.

2. People who are engaged in heavy physical labor and stand for a long time should wear elastic socks to keep the superficial vein in a state of oppression.

3. Women should pay special attention to their legs during menstruation and pregnancy, take more rest and massage their legs frequently to help blood circulation and avoid varicose veins.

Etiology of varicose veins

Clinical pathogenic factors of varicose veins can be divided into congenital factors and acquired factors. Congenital factors mainly include congenital anomalies of blood vessels and congenital anomalies of blood vessel walls. There are many acquired factors, mainly occupation, age and diet. Here is a detailed introduction to the causes of varicose veins:

First, congenital factors

1. Congenital weak vein wall: When blood circulates in the vein, it will exert certain pressure on the vein. If the vein wall is weak and can't bear these pressures, it will cause the blood return to be blocked and stagnate in the meridians of the lower limbs, resulting in varicose veins.

2. Congenital venous valve insufficiency: venous valve is an important "helper" for venous blood of lower limbs to return to the heart. If the valve function is damaged or lost, blood will flow backwards, which will lead to varicose veins of lower limbs for a long time.

Second, acquired factors.

1. Occupational factors: People who need to stand, sit and squat for a long time, and people who have been engaged in heavy physical labor for a long time, are prone to damage the veins of lower limbs and varicose veins.

2. Age factor: With the increase of age, the elasticity of human vascular wall gradually decreases and becomes slack, which is prone to varicose veins. So under the same conditions, the elderly are more prone to varicose veins.

3. Dietary factors: People with unhealthy diets such as high fat and high salt have higher blood viscosity, so the probability of varicose veins is higher.

Therefore, in daily life, obese people, middle-aged and elderly people, pregnant women, workers who often stand, patients with pelvic tumors, patients with deep vein thrombosis, and those with congenital weak vein walls are prone to varicose veins.
