Common Factors That Cause Thread Veins on Legs

Thread veins are microscopic veins that can occur on the face, thighs, or calves. Thread veins are sometimes referred to as spider veins, although their medical name is telangiectasia varicose veins. Thread veins on legs are thin, red, irregular lines that run just beneath the skin’s surface. They usually affect your face, especially your cheekbones and nose. Spider veins can make people feel self-conscious about their appearance and confidence.

What do Thread Veins mean?

When microscopic veins collect beneath the skin’s surface, generating red, blue, or purple discolorations, they are referred to as “thread veins.” The form of the bruises gives thread veins its name. Thread veins on legs can be very tiny in some circumstances. Others are more obvious. They may make you feel self-conscious, but they’re entirely safe, and any treatment is usually done solely for aesthetic purposes.

What Causes Thread Veins?

The fundamental reason is faulty valves in feeder’s veins. Healthy valves inside feeder veins cause thread veins in the leg, hand, and face, enabling blood to flow backward rather than upward toward the heart. Some of this stuck blood can result in thread veins, which are non-functional, “dead-end” veins that form beneath the skin’s surface.


Blood vessels that are red or bluish-purple appear on the legs or thighs, although they can also appear on the face, forearms, or hands. Spider veins are normally painless. However, they can occasionally induce a dull ache or a burning feeling like liquid rhinoplasty.

How to Avoid Thread Veins

Despite the fact that thread veins that do not cause discomfort or restless legs do not require treatment, some people prefer to have them treated since they are ugly. Treatment for thread veins can be quite effective.

Thread Veins Affect Who?

Many of us will probably develop vein problems. Spider veins are frequently inherited, so if your previous generations have them, you’re more likely to get them as well. If you get pregnant or have a work or lifestyle that demands you to stand for lengthy periods, your symptoms may worsen or develop.

Common Spider Vein Risk Factors

Spider veins are caused by several conditions that are similar to those that cause varicose veins, including:

  • Genetics: If other family members have thread veins, your chances of developing them increase.
  • Age: Though thread veins aren’t exclusive to the elderly, the condition does worsen over time. This is since vein valves wear down more quickly over time. This makes adequate blood flow more challenging, which can lead to blood pooling.
  • Pregnancy: During pregnancy, blood volume nearly doubles to sustain the fetus, resulting in enlarged veins and possibly thread veins.
  • Obesity: Weight gain puts additional strain on the veins.
  • Gender: Spider veins are more common in women because of hormonal changes between pregnancy and menopause.
  • Sedentary lifestyle: Long periods of sitting or standing reduce blood flow and might result in blood pooling.

Final Thoughts

Some patients seek treatment to improve their appearance, like liquid rhinoplasty, while others seek pain relief. The good news seems to be that thread veins, and their causative factors are both treatable, and RejuvaMed Skin Clinic’s comprehensive approach treats vein disease as a whole, not just the symptoms.
