Varicose veins causes
Varicose veins causes are damaged or weakened valves. When valves are weakened or damaged they cannot pump blood to flow to the veins as normal. The inability of the valves to pump blood causes the blood to gather in the vein and caused the veins to become varicose.
The veins contain tiny one-way valves. These valves open to let the blood flow through, and close so as not to allow the blood to flow backwards. The valves can become weakened and fail to function properly. Blood then gather in the veins, causing them to become enlarged and swollen.
Why the valves in the veins become weakened is still not fully understood but there are a number of risk factors known to cause varicose veins.
Gender.The female hormones relax the walls of veins making it susceptible to leaking. This is why women are more affected than men. Hormones are not the only varicose veins causes in women (see pregnancy below).
Age.One of the main varicose veins causes in people is old age. The older one gets the more elasticity the veins loses, the more the valves within them stop functioning as well.
Genetics.People with a family member with the condition is also at risk of developing the condition. Genetics are important in understanding varicose veins causes because we inherit our physical and behavioural characteristics from our parents. Meaning that varicose veins may be partly caused by the units of genetic material we inherit from our parents.
Weight.Undoubtedly being overweight or obese is an important risk factor. People who are obese or severely overweight puts additional pressure on their veins. It makes them to work harder to be able to send the blood back to the heart, putting more pressure on the valves and they become susceptible leaking. Losing weight is therefore a way of preventing varicose veins.
Occupations.Varicose veins causes that are linked to occupations are where you have to stand on your feet on a long period of time. Any occupation requiring long periods of standing on your feet increases the chances of developing varicose veins. The main reason for this is when you are standing on your feet for long periods it becomes hard for blood to flow upwards.
Pregnancy.One of the well-known varicose vein causes is pregnancy. The amount of blood in the body of a pregnant woman increases to help support her growing baby, putting more strain on her circulatory system. Also when pregnant women have increased hormone levels causing the muscular walls of their blood vessels to relax. These risk factors make pregnant women more likely develop varicose veins.
During pregnancy varicose veins may also appear as your womb begins to develop. This causes the expanding womb to place additional pressure on the veins in the pelvic area.
Varicose veins cause linked to pregnancy are not permanent. Most pregnant women who develop them will recover noticeably after delivery.
Other Varicose Veins causes. Although rare, the some health conditions are known varicose veins causes. They include abnormal blood vessels, a previous blood clot, and a swelling or tumour in the pelvis.
