Causes of Varicose Veins
WHAT ARE VARICOSE VEINS?
Physicians have determined that varicose veins form when blood vessels become weak and malfunction although, the exact causes of varicose veins and why these blood vessels become weak and malfunction, is still unknown. In normally functioning veins, one-way valves open as blood flows toward the heart and the valves close to prevent blood from flowing backward. When these valves malfunction, blood pools in the veins. Over time, the increased pressure can cause additional valves to fail. When the additional valves fail, the result is a buildup of pressure that weakens the vein walls and causes them to bulge. This is called venous reflux, or venous insufficiency, and leads to the development of vein problems including varicose veins and spider veins.
Whether venous reflux is a product of dysfunctional valves or weakened walls, the end result is usually bulging varicose veins. These bulging veins are often accompanied by leg pain, swelling, burning, itching, and or discoloration and this is usually when varicose vein treatment options are sought out.
WHAT ARE THE CAUSES OF VARICOSE VEINS?
There are a number of factors that seem to contribute to poor vein or blood vessel functioning which can result in varicose veins. These contributing factors include:
- Conditions that put excess pressure on leg veins – including standing for long periods of time, obesity and pregnancy
- Hormonal changes that relax vein walls – This puts women at a greater risk than men
- History of blood clots
- Conditions that increase pressure in the abdomen, such as tumors, constipation and tight garments
- Previous venous surgery
- Normal aging process
