What is a varicose vein?
varicose veins refer to the tortuous and dilated veins caused by blood stasis, weak venous wall and other factors. Varicose veins can occur in many parts of the body. For example, hemorrhoids is actually a kind of varicose veins, the most common of which is the lower limb. Varicose veins may also be secondary manifestations of other lesions, such as vena cava occlusion, and the primary disease should be actively treated.
what are the causes of varicose veins
there are many causes of varicose veins, mainly including long standing and sedentary, constipation, obesity, smoking and drinking, etc. Specifically:
1, long standing and sedentary
people who need to stand or sit for a long time are prone to varicose veins of lower limbs, such as salesmen, teachers, white-collar workers, etc. Because they need to maintain the same posture for a long time, so that the blood circulation does not accumulate in the veins of the lower limbs. In the long run, the venous valves are damaged and the venous pressure is too high, resulting in varicose veins of the lower limbs.
2,
obese people have bad posture and abnormal gait, which can further cause joint infection and osteoarthritis. It is difficult to transport the fat from the lower limbs to the large veins of the body.
3 and constipation
constipation is also easy to induce varicose veins. Long term constipation often squats for a long time during defecation, which inhibits the blood circulation of lower limbs and legs, resulting in internal pressurization of blood vessels, blood gambling and damage of vascular valves. Therefore, it is also easy to cause varicose veins.
4. Smoking and drinking
people who often smoke and drink are easy to cause vascular sclerosis, affect blood circulation and are not conducive to health.
