Chronic venous insufficiency and varices

Asevere varicosisit can lead to chronic venous insufficiency. The venous valves, when functioning well, ensure the transport of blood from the periphery to the heart.

You may not know it, but your cardiovascular system is made up of arteries (which start from the heart and carry oxygen to the tissues) and veins (without oxygen, which start from the periphery and thenovercome the force of gravity and return to the heart).

If the vein valves are damaged, the veins are under too much pressure and are overstretched. This causes a slowdown in the return of blood which, in turn, can determine a stagnation of blood at the level of the capillary network which hinders the removal of metabolic products and especially of the interstitial fluid of the tissues (this is why those who have problems with the circulatory system is easier to suffer from heaviness in the legs, swollen legs and feet, swelling in the feet is nothing more than the consequences of the non-reabsorption of liquids by the circulatory system).

If venous insufficiency is severe and chronic, together with the interstitial fluid, hemoglobin can also accumulate in the tissues: this is why elderly people tend to have a brownish discoloration of the skin of the ankles.

Varicose veins or varicose veins: what to do?

It is important to contact your doctor in order to evaluate various interventions. The doctor will ask you for information on the symptoms and will make a thorough examination, examining the possible presence of swelling or changes in skin color.

To investigate the presence of edema (fluid stagnation) and to perform a more precise diagnosis, the doctor may prescribe an ultrasound or sonography. Sonography allows you to check how fast the blood flows through the veins.

Not all varicose veins require treatment and this is also why medical advice is essential.
