Varicose veins (or varicose veins) are dilated veins that can appear meat, dark purple or blue color. Often they resemble the beads and are enlarged and tortuous, swell and are found on the skin surface. Varicose veins are commonly located on the back of the calf or along the inside of the thighs. During pregnancy special varicose veins called hemorrhoids can form in the vagina or around the anus.
also known by the name of capillaries, telangiectasias are similar to varicose veins, but they are smaller. They are usually red or blue and are closer to the surface of the skin than varicose veins. They may look like the branches or spider webs with their thin serrated lines. Generally they show on the legs and face and can either cover the very limited skin area that a very extensive.
Between 50% and 55% of American women and between 40% and 45% of American men suffer from venous problems: varicose veins then hit one in two people starting from the age of 50.
The heart pumps the oxygen-rich blood and nutrients to the whole body. The arteries carry blood from the heart to the body’s periphery, while veins carry blood oxygen-free from every district of the body to the heart.
The veins have valves of the type “one-way flaps”, which promote the transport of blood in one direction only; in the legs these valves push blood upwards and prevent its descent towards the bottom. If such valves are weakened, the blood can accumulate in the veins and capillaries because no longer able to be effectively pushed towards the heart: this problem is called venous insufficiency. The accumulation of blood tends to dilate the vein and make varicose, spider veins can also be caused by blood reflux. hormonal changes, heredity and exposure to the sun can also favor the appearance of unsightly capillaries.
There are many factors that increase the likelihood that a person will develop this problem, including:
- Advancing age.
- Having family members with vein problems or born with little elastic venous valves.
- Hormonal changes that occur during puberty, pregnancy, and menopause. Also taking birth control pills and other medicines containing estrogen and progesterone increases the risk of the appearance of varicose veins.
- During pregnancy there is a considerable increase of the amount of blood in the body and this can cause dilation of the veins. In addition, the expanding uterus produces pressure on the veins. Varicose veins usually improve within three months after delivery, usually every subsequent pregnancy the first to result in increased abnormalities in veins.
- Obesity, a wound to the leg, a prolonged standing position and other factors that can weaken vein valves.
- Exposure to the sun, which can encourage the emergence of spider veins on the cheeks and nose of people with fair complexions.
The force of gravity, the pressure of the body weight and the task of transporting the blood upward to the heart from the peripheries of the body causes the legs are the main body area for the appearance of varicose veins and capillaries. Compared to the other veins of the body, the legs have the most difficult task of carrying the return blood to the heart. They therefore bear considerable pressure, which can be stronger than the venous valves.
The signs and symptoms of varicose veins include:
- Large veins visible on the skin,
- A slight swelling of the ankles and feet,
- Sore legs or ‘heavy’,
- Pain or leg cramps,
- Itching in the legs, especially at the bottom and ankles. This symptom is in some cases erroneously diagnosed as a symptom of dry skin.
- Discolored skin in the area around the varicose veins.
The capillaries instead are generally formed in the upper part of the body, including the face. classic signs are blue and red veins grouped like a spider web, which occur on the legs and face.
Consult your doctor if any of these signs and symptoms, as they may also be an indication of further and in some severe cases disorders.
Sometimes doctors diagnose varicose veins based solely on a physical exam, additional tests and procedures may be done to determine the extent of the problem and to rule out other diseases.
If you have varicose veins you can get see a specialist in vascular medicine or by a vascular surgeon or find a home remedies for varicose veins, these are doctors specializing in blood vessel disorders. You can alternatively consult a dermatologist, doctor who specializes in skin diseases.
To detect the presence of varicose veins your doctor examines your legs while you’re standing or sitting with his legs dangling, it will ask you a few questions regarding the signs and symptoms that occurred, including any kind of pain that you have suffered.
Diagnostic tests and procedures
Doppler ultrasound: Your doctor can recommend a Doppler ultrasound to monitor blood flow in the veins and to check for possible blood clots. Doppler ultrasound uses sound waves to provide images of the internal flows of the body. During this test, a handheld device will be placed on your body and moved back and forth on the affected area. A computer will convert the sound waves into a picture that mimics the blood flow of the arteries and veins.
Angiogram: Though less common, your doctor may prescribe an ‘angiogram to get a more detailed view of the blood flow in blood vessels. For this procedure, a dye is injected into the veins, which allows you to delineate them on radiographic images. A ‘angiogram can help your doctor to confirm the presence of varicose veins or other problems.
Typically the capillaries do not require medical treatment, usually instead varicose veins tend to worsen and to expand further, to cause problems to the heart in the most serious cases:
Severe venous insufficiency. The accumulation of blood in the veins slows the return of blood to the heart, which can cause blood clots and dangerous infections. The clots can be extremely dangerous because they can move from leg veins and travel up to the lungs, where they constitute a serious threat to life as they can be an obstacle to the smooth functioning of the heart and lungs.
Infections and skin ulcers may be present on skin tissue in the appearance of varicose veins.
