So how to prevent varicose veins of lower limbs? Here are ten prevention techniques for you.
First, avoid standing for a long time.
Venous blood, especially venous blood of lower limbs, needs to overcome gravity when it returns to the heart. At this time, the pressure on the venous wall and venous valve of the lower extremity will increase and remain upright for a long time, and the venous wall and venous valve are always in a high pressure state, which is easy to induce varicose veins of the lower extremity.
Second, the combination of static and dynamic
Sitting for a long time will lead to poor venous blood return of lower limbs. When sitting, calf muscles are in a relaxed state, which is not conducive to venous blood return, and even leads to reflux disorder and blood return.
Third, avoid crossing your legs.
When Erlang's legs cross, the padded legs are compressed, which easily affects the blood circulation of lower limbs. It's easy to get numb when the leg stays in a posture for a long time. If the blood circulation is blocked again, it is likely to lead to varicose veins in your legs and even blood embolism.
Fourth, muscle exercise.
Venous reflux is affected by muscle contraction and negative pressure in chest cavity. The stretching and contraction of calf muscles acts as a water pump, which sends the blood flowing from the artery to the leg back to the heart through the vein. The muscles contract rhythmically and squeeze the venous tubes distributed between them, so that the blood flows back to the heart along the opening direction of the venous valve.
Verb (abbreviation for verb) pays attention to prevention.
Some people will have congenital deep venous valve insufficiency, and this kind of people are more likely to cause varicose veins of lower limbs than those with complete valve function, so we should pay attention to prevention for this kind of people.
Six, control weight
Obesity easily destroys venous valves, leading to increased venous pressure and varicose veins. Excess fat will be wrapped in blood vessels. Over time, the extrusion and injury of fat to blood vessels and organs will lead to slow blood flow and poor blood circulation, and then induce varicose veins.
Seven, quit smoking and limit alcohol
Alcohol can promote blood circulation, accelerate blood circulation, stimulate blood vessel dilation, and easily lead to varicose veins; Smoking will increase the content of carbon monoxide in blood, make platelets coagulate, increase blood viscosity, gradually form thrombosis and vascular occlusion, and cause varicose veins of lower limbs due to blood circulation disorder of limbs.
Eight. Pregnancy prevention
The increase of lutein during pregnancy causes vasodilation, and the increase of systemic blood flow during pregnancy separates the originally closed venous valve, resulting in venous blood reflux. In addition, the enlargement of the fetus and uterus will compress the pelvic vein and inferior vena cava, hinder the blood return of lower limbs, cause the venous pressure to rise, and more easily cause varicose veins of lower limbs.
During pregnancy, mothers should avoid sitting for a long time, get up every half hour, do walking exercise for more than half an hour every day, and try to use the left lateral position in the middle and late pregnancy, which will help alleviate the oppression of the uterus on the deep abdominal vein.
Nine, control diet
Eat more low-fat and low-calorie foods, especially vegetables, kelp, jellyfish, laver, fungus, bean products and foods containing vitamins B and C. Too salty foods will raise venous blood pressure, high fat and cholesterol will raise blood lipids, and irritating foods will raise plasma cholesterol and triglyceride concentrations, leading to venous sclerosis. At the same time, it will also cause the deposition of venous blood lipids and make venous blood vessels contract.
Auxiliary reflux
At rest, consciously assist venous blood return of lower limbs. By raising the end of the bed and raising the lower limbs, venous blood can better return to the heart by gravity, thus reducing the pressure on the venous wall and venous valve.
