INFORMATION ABOUT VARICOSE VEINS
Varicose veins are enlarged or swollen veins that are clearly visible above the surface of your skin. Their purple and blue color differs in shade from the normal vein. Varicose veins also look twisted and bulging out of the skin. They are commonly found on the legs or at the back of a person’s calves.
The onset of varicose veins is a symptom of an unhealthy circulatory system. When the valves in a person’s veins do not work properly, blood flow is restricted which causes blood pooling. The pooling of blood causes the veins to develop into varicose veins.
Causes of Varicose Veins
Though the causes of varicose veins are known, the reason for the cause is hotly debated by people in medical circles. Some doctors think that there exists a genetic problem that causes some people to not have the correct number of valves in their veins. Some people can have the correct number of valves but most of them are not working properly.
Another probable explanation is that some people are genetically predisposed to have thin vein walls. The lack of thickness in the veins causes the blood from the valves to leak. With the constant pressure of blood trying to get out, the veins enlarge which result to varicose veins.
Another manifestation of varicose veins is that blood tends to go the wrong way instead of going back to the heart. Because of the leaky nature of varicose veins, there is not enough pressure for the valves to push the blood to the heart. Therefore, blood flow reverses and flows to the enlarged valves.
Risk Factors for Varicose Veins
There are a number of factors that can worsen the situation for people with varicose veins. First, pregnant women can develop varicose veins because of the added blood volume that adds pressure on the vein walls. Hormonal changes in a pregnant woman can help develop varicose veins.
Obesity is also a major risk factor for varicose veins. Obesity is greatly related to several circulatory problems. Abnormal number of cells restricts normal blood flow that enlarges the veins of a person. Aside from obesity, other conditions such as chronic constipation, urinary problems, and chronic cough cause the person to strain blood flow for along period that can severely affect regular blood flow.
To prevent varicose veins, take care of your blood flow. Constant exercise and diet is the primary step to having a healthier circulatory system.
