Causes of varicose veins

Varicose veins are a common disease that causes great harm to patients, so patients must pay great attention to this disease. So what information should we know about varicose veins? We need to know what varicose veins are and what causes them. This will help us fully understand this disease.

In addition, after understanding the causes of varicose veins, we should know how to prevent and treat varicose veins. Let’s take a look at our introduction to the causes of varicose veins below.

Varicose veins refer to the tortuosity and dilation of veins due to factors such as blood stasis and weak venous walls. Varicose veins can occur in many parts of the body. For example, hemorrhoids are actually a type of varicose veins. Other clinically visible varicose veins include esophageal varicose veins, varicocele, abdominal wall varicose veins, etc. The most common site of varicose veins is the lower extremities. It is worth emphasizing that varicose veins themselves may be a secondary manifestation of other lesions, such as vena cava occlusion, and the primary disease should be actively treated.

1. Obese people should lose weight. Although obesity is not the direct cause, excessive force on the legs may cause poor venous return in the legs and aggravate venous dilation.

2. For people who engage in heavy physical labor or stand for a long time, it is best to wear elastic stockings to keep the superficial veins in a compressed state.

3. Women should pay special attention to their legs during special periods such as menstruation and pregnancy. They should get more rest and massage their legs frequently to help blood circulation and avoid varicose veins.

Varicose veins of the lower limbs can be treated by wearing elastic stockings, injecting sclerosing agents, surgical stripping, etc. Deep venous valve insufficiency can be treated by valve repair surgery and laparoscopic perforator ligation, etc. Varicose veins in the lower limbs may also indicate the presence of other diseases, and the primary disease needs to be actively treated; if the deep veins have poor venous return, surgical treatment of the superficial veins should be more cautious.

Causes of varicose veins

There are many causes of varicose veins in the lower limbs, the most common of which is simple superficial varicose veins in the lower limbs, the main cause of which is the insufficiency of the femoral saphenous vein valve. Another important cause is primary deep venous insufficiency (PDVI) of the lower extremities, which is often combined with great saphenous vein valvular insufficiency and often manifests as tortuous dilatation of the superficial veins. In addition, post-deep vein thrombosis syndrome in the lower limbs causes compensatory tortuous dilatation of the superficial veins due to poor deep vein reflux; lower limb arteriovenous fistula and venous malformation hypertrophy syndrome can also present with varicose veins of the lower limbs; obstruction of the inferior vena cava reflux, such as Budd-Chiari syndrome, can also lead to varicose veins of the lower limbs.

Above we introduced what varicose veins are. We know that varicose veins are a common disease. When varicose veins occur, we must actively treat them. The above article introduced in detail how to prevent varicose veins and how to treat varicose veins. The above article also specifically introduced the causes of varicose veins.
