Why do varicose veins cause itchy skin?

Although many of us are familiar with the symptoms of soreness, pain, and edema of varicose veins in the lower extremities, itchy skin is also one of the symptoms of venous diseases!

To understand this, let us take a closer look at the human circulatory system.

The heart pumps arterial blood rich in oxygen and nutrients. This "fresh" blood is supplied to all the cells of the body through the arteries.

On the other hand, the veins bring the "used" blood back to the heart and lungs and other organs to "purify" and use it again, so that the cycle goes back and forth, and the metabolism continues.

Because veins carry "used" blood, blood is no longer rich in oxygen; on the contrary, blood in veins contains a lot of metabolic waste products, such as carbon dioxide and lactic acid produced by body cells. If these metabolic waste products are not quickly brought back to the heart, lungs, liver and kidneys, where they are "purified", they will be toxic to the body.

Because the blood in the legs needs to bear the action of gravity, it moves upwards. If the venous valve function fails, it will cause excessive pressure in the leg veins and excessive  astagnation of blood.

Therefore, the legs are the first to bear the brunt of vein problems, and vein problems will affect the skin to a certain extent, resulting in skin symptoms.

In winter, part of the itchy legs is caused by "dry skin", but sometimes despite trying a variety of creams and lotions to moisturize, the symptoms still exist.

This is frustrating!

However, if the root cause of the itching is venous disease, creams and lotions may be helpful, but they will not solve the root cause of the problem.

This seemingly annoying symptom should be regarded as a warning sign.

If left untreated, this chronic irritation can cause irreversible deterioration of the skin and surrounding tissues.
