what causes spider veins


Spider veins, also known as varicose veins, are a common occurrence for women. In fact, nearly 50% of women in America have varicose veins or are at risk of developing this condition. Various factors can increase your risk of developing spider veins, but what causes spider veins?


In this article, we’ll go over what causes spider veins to develop and what treatment options are available today.


What Causes Spider Veins


To begin, what causes spider veins on legs, and are spider veins dangerous?


Spider veins are damaged veins that occur when the valves located inside the vein become weakened. This causes blood flow to reverse backward and accumulate inside the vein. When blood accumulates inside the vein, pressure is put on the vein walls, leading to it becoming weakened. This weakened state then leads to what we see as varicose veins.


There are a few risk factors that contribute to spider veins. These spider vein causes may be:


  • Genetics

  • Pregnancy

  • Obesity

  • Aging

  • Hormones

  • Long periods of sitting or standing

  • Previous vein damage


While spider veins can lead to symptoms like tenderness, itching, fatigue, or aching, they are generally not dangerous. However, some potential complications can include external bleeding or blood clots.


How to Prevent Spider Veins


While varicose veins are typically not dangerous, preventing them can save you from those future complications such as blood clots or skin ulcers. There are a few ways in which you can promote healthy blood flow through your body in order to keep your veins working properly. These include:


  • Exercising as much as possible to keep blood flow regular and healthy

  • Keeping your legs elevated to prevent blood from pooling and promote blood flow to the heart

  • Invest in proper footwear to induce good blow flow and reduce pressure on the veins around your legs and ankles



It should be noted that for those with a family history of varicose veins, prevention may be more difficult. However, treatment options are available.


Spider Veins Treatment Options


There are a variety of direct and indirect treatment procedures available for those living with varicose veins. Your doctor can suggest the best course of treatment depending on your situation. Suggested treatment options may include:


  • Compression stockings worn daily

  • Take over-the-counter anti-inflammatory to reduce swelling and pain

  • External laser treatments



In addition to these less invasive procedures, your doctor may suggest sclerotherapy, which is a common form of treatment for those with small varicose veins. It is a treatment that improves circulation and reduces swelling. The treatment includes your dermatologist injecting a chemical into the spider vein, irritating the wall of the weakened vein. The injected site is then massaged and compression stockings are placed on each leg.


After a time of observation, you are free to go home. Your doctor will most likely give you instructions for daily activity and strict usage of compression stockings.
