Varicose Veins
The Who and Why of Varicose Veins
Varicose veins or Varicosis is the sequel
generally to phlebitis. Varicose veins are very common,
primarily affecting women. More than 20 percent of women
develop some form of varicose veins, either during
pregnancy or as they age. Varicose veins are abnormally
enlarged veins that can be flesh colored, dark purple or
blue. They normally appear close to the skin’s surface and
occur on legs as a result of obstruction of the veins or
malfunctioning valves inside the veins like prolonged
pressure.
Varicose veins are not a disease in themselves although they
can cause daily irritation and worry. People with this problem
should consult their GP to discuss whether treatment is
necessary. Varicose veins are enlarged veins that result from a
weakening in the vessel wall. They generally result from high
pressure and congestion within the veins. Varicose veins are
obvious, dilated veins found just under the skin. In normal
veins the valves make sure blood only moves in one
direction.
Varicose veins are veins that have become enlarged and swollen
with blood. Veins have valves along their inner surface. The
purpose of these valves is to keep blood moving toward the
heart and not to flow backward toward the feet or pool in the
veins of the legs. Varicose veins are almost always caused by
valve deterioration in the veins of the leg. Varicose veins
tend to occur in superficial veins, those are the veins closer
to the surface of the skin. Varicose veins are one of the
commonest reasons for surgical intervention in the Western
world and yet their aetiology is poorly understood. Remodelling
of the extracellular matrix is an important cause of the
changes in the walls of varicose veins, and alterations in the
balance between matrix-degrading metalloproteinases (MMP) and
their inhibitors (TIMP) have been proposed to play a role.
Varicose veins are a long-term problem, but symptoms can wax
and wane. If you are pregnant and experiencing severe problems
with varicose veins, your symptoms will improve following
delivery. Varicose veins are more common in women, and people
are more likely to get them as they get older. These veins can
be genetic. Varicose veins are frequently treated by
eliminating the varicose veins to let blood flow through the
remaining healthy veins. This can be done by sclerotherapy or
surgery.
Varicose veins are deeper than spider veins. Their gnarled and
enlarged appearance is caused by swollen blood vessels.
Varicose veins are caused by a malfunction of the valves in
superficial leg veins. As a result, the valves may have trouble
closing - leading to venous reflux. Varicose veins are easy to
see, especially when you are standing. The doctor will also
check your legs for swelling, tender areas, skin colour
changes, ulcers, and other signs of skin breakdown.
Varicose veins are generally less common in men. Still,
approximately 25 percent of men 30 to 40 years of age, and
almost 50 percent of men age 70 and older have benign vascular
lesions. Varicose veins are caused by swollen or enlarged blood
vessels. The blood vessels have enlarged due to a weakening in
the vein's wall or valves. Varicose veins are the undesirable
pathways where venous blood refluxes back into the congested
extremity. Ablation of the varicose pathways invariably
improves overall venous circulation.
Varicose veins are usually visible through the skin and may
appear bluish in color. A common symptom is swelling and/or
weakness in the legs after prolonged standing or sitting.
Varicose veins are bulky bluish veins that usually appear on
the legs during pregnancy. This happens due to your body is
compensating for the extra blood flow that is going to your
baby. Varicose veins are dilated superficial veins normally
invisible underneath your skin. There are normally two systems
of veins in your leg: a superficial system and a deep
system.
Compression hosiery is the
traditional non-operative method of treating varicose veins.
While it improves symptoms and venous blood flow, this
improvement is restricted to the time the stockings are worn,
and poor compliance is a major limitation. Compression stockings are worn after the procedure, and walking is
encouraged.
