What is a venous disease?
venous disease is a health condition caused by abnormal or damaged veins, blood vessels that carry blood towards the heart. The venous disease occurs when the vein suffered damage to the valves that regulate the direction of blood flow, resulting in what is called venous insufficiency, because the ability of the circulatory system sends deoxygenated blood back to the heart. This allows blood to pass through damaged veins to take or leak, most often in the feet, which further damages the veins by expanding and can cause damage to nearby tissues. Some forms of venous disease have effects that are primarily cosmetic, but more serious forms can cause pain, mobility damage and health problems such as skin ulcers. In some cases, venous disease may be fatal, causing skin cancer or fatal blood clot.
venous disease has several potential causes. In some cases, the result of congenital defects in the veins that prevents the valve in FUNccis. They may be caused by inflammation of the veins called flebitis, which in turn can be caused by infection, physical trauma or chemical irritants. Blood clots can lead to venous disease by stretching or inflammatory veins. Diseases may be caused by injuries of blood vessels, activities or professions that place physical stress on the feet or pregnancy. The disease is more common in women than in men due to hormonal effects and the risk increases in people who are overweight or high.
The effects of the diseases are usually observed primarily in the legs and legs. In a person suffering from venous insufficiency, association and blood leak on the lower limbs may cause pain, inflammation and a feeling of difficulty while standing or walking. The skin color may occur around the ankles, and in more serious cases, ulcers may appear on the skin in the same area. In heavy -class, venous disease can cause sufficient BolEst or the difficulty of the legs to interfere with the ability to build or walk for a longer period of time. Blood accumulation in the legs can also cause what would normally be minor injuries to lead to a serious blood loss.
Some effects of venous disease are observed directly in the veins themselves. Distension of small veins on the surface of the skin suffering can cause clusters of distinted blood vessels known as a cobweb vein, colored blue, red or purple to become visible on the skin and in some cases become painful. A similar problem in larger veins results in varicose veins that cause the affected veins to turn and enlarge, often visibly bulging against the skin and becoming coverage or as a cord. Both conditions are most commonly found in their feet, but may also occur elsewhere.
The venous disease causes blood clots to form because damaged veins slowed blood flow and Greateric sensitivity to inflammation from injury. If the clot remains on the bowlYou cause further inflammation of the vein or thrombophlebitis, which further worsens the damage to the vein. If the clot is formed in a deep vein, a condition called deep venous thrombosis is developing, where there is a significant risk that the clot will be released and starts to travel by circulatory system until it covers in the arteries of the lungs, causing potentially fatal lung embolism blocking.
Long -term venous disease may deteriorate over time as damage is accumulated, resulting in a condition called chronic venous insufficiency. Swelling and inflammation become more serious and eventually prevent blood flow so seriously that it disrupts the flow of nutrients and oxygen into the skin suffering. The skin is damaged and inflamed, which eventually leads to a condition known as venous stingal dermatitis, in which the skin is dry, leather and faded. Incorporated blood association in the feet can also produce ulcers in the skin known as the venous stasis of ulcers, which are painful and in some cases become cancerous.
