If you can prevent varicose veins in your daily life, you can still reduce the possibility of varicose veins.
So how to prevent varicose veins of the lower limbs? Here are ten prevention tips.
1. Avoid standing for long periods of time
Venous blood, especially the venous blood of the lower limbs, needs to overcome gravity when it returns to the heart. At this time, the pressure on the vein walls and venous valves of the lower limbs is borne. Will increase. If you stay upright for a long time, the vein walls and vein valves are always under high pressure, which can easily induce varicose veins in the lower limbs.
2. Combination of movement and stillness
Long-term sitting posture will lead to poor venous blood return in the lower limbs, and the calf muscles are in a relaxed state when sitting, which is not conducive to venous blood return, and may even lead to reflux obstruction, The phenomenon of backflow of blood.
3. Avoid crossing one's legs
When crossing one's legs, the leg being padded will be compressed, which can easily affect the blood circulation of the lower limbs. If your legs remain in the same position for a long time, they will easily become numb. If the blood circulation is further blocked, it is likely to cause varicose veins in the legs or even thromboembolism.
4. Muscle exercise
During venous return, it will be squeezed by muscle contraction and affected by negative pressure in the chest. The stretching and contraction of the calf muscles act as a water pump, pumping water through the arteries. The blood that flows to the legs is returned to the heart through the veins. The rhythmic contraction of the muscles squeezes the venous tubes distributed therebetween, causing blood to flow back to the heart in the direction of the opening of the venous valves.
5. Focus on prevention
Some people have congenital deep vein valve insufficiency. This group is more likely to cause varicose veins in the lower limbs than people with fully functional valves. , so precautions should be taken for this group of people.
6. Control weight
Obesity can easily damage venous valves and cause excessive venous pressure, leading to varicose veins. Excess fat will wrap around blood vessels. Over time, the compression and damage of fat to blood vessels and organs will lead to slow blood flow and poor blood circulation, which will aggravate the induction of varicose veins.
7. Quit smoking and limit alcohol consumption
Alcohol has a blood-activating effect. It accelerates blood circulation, stimulates blood vessel dilation, and easily causes varicose veins. Smoking increases the carbon monoxide content in the blood and causes platelet loss. Aggregation, increased blood viscosity, gradual thrombosis and vascular occlusion, resulting in limb blood circulation disorders, thereby causing varicose veins in the lower limbs.
8. Prevention during pregnancy
The increase in progesterone during pregnancy causes the expansion of blood vessel walls. In addition, the increase in systemic blood flow during pregnancy causes the originally closed venous valves to separate, causing venous blood to flow backwards. In addition, the growth of the fetus and uterus will compress the pelvic vena cava and inferior vena cava, blocking the return of blood in the lower limbs and causing increased venous pressure, which is more likely to cause varicose veins in the lower limbs.
Pregnant mothers should avoid sitting for long periods of time, get up and move every half an hour, and walk for more than half an hour every day. Try to sleep on the left side during the middle and late stages of pregnancy, which can help reduce the impact of the uterus on the deep veins in the abdominal cavity. oppression.
9. Control your diet
Eat more low-fat, low-calorie foods, especially green vegetables, kelp, jellyfish, seaweed, fungus, soy products and foods containing vitamins B and C. wait. Food that is too salty will increase venous blood pressure, high fat and high cholesterol will increase blood lipids, and spicy food will increase the concentration of plasma cholesterol and triglycerides, causing venous sclerosis. At the same time, it will also cause the deposition of blood lipids in the veins, narrowing the veins and blood vessels.
10. Assisted reflux
Consciously assist the venous blood reflux of the lower limbs during rest. You can use the effect of gravity to assist venous blood by raising the end of the bed, raising the lower limbs, etc. Better return flow to the heart to reduce pressure on vein walls and vein valves.
