Discovering suddenly visible blood vessels can be startling, often raising concerns about their implications for our health. In this article, we delve into the reasons behind the sudden appearance of these vessels, distinguishing between benign conditions and potential indicators of underlying health issues such as thread veins or varicose veins.

Suddenly visible blood vessels can be early signs of thread veins or varicose veins

There is a significant difference between visible blood vessels of the type seen in healthy people and visible blood vessels of the type that can be the beginning of thread veins or varicose veins. If the blood vessels suddenly become visible without having been there for some time, it may be a sign that thread veins or varicose veins are about to develop.

What distinguishes thread veins is that they wind like nets just under the skin and have a red to bluish color. This is not the case when visible blood vessels appear in, for example, athletes. Thread veins cannot be felt on the outside of the skin either, they are only visible through it.

CEAP: C1 - Thread Veins

Varicose veins, on the other hand, are bluish and tortuous veins that are palpable on the outside of the skin. Varicose veins often appear after thread veins have been present for some time.

How do you know if a suddenly visible blood vessel will turn into a varicose vein?

It is not possible to determine at an early stage whether the suddenly visible blood vessels will develop into thread veins or varicose veins. But you can pay attention to how these blood vessels develop. The difference in the symptoms between thread veins and varicose veins are relatively easy to identify and if you do, you can see with some certainty whether it is thread veins or varicose veins.

Because thread veins and varicose veins occur as a result of defects in the venous valves, the blood that should be pumped towards the heart instead flows back down the vein where there is no room for it, which causes pools of oxygen-poor blood to form which usually meanders along the lower legs.

This with low oxygen is a significant difference compared to if the suddenly visible blood vessels are on an athlete, then the blood vessels are not tortuous because the blood in these veins is pumped with good speed towards the heart.

What should you do yourself if a visible blood vessel develops into a varicose vein?

What you can do yourself is to take measures to improve blood circulation in the body. A good blood circulation facilitates the blood flow in the veins, which means that the blood can flow well even if the vein valves do not work as they should. An improved blood circulation does not solve the problem of the venous valves, which have reduced function, but it counteracts the onset of the symptoms, of which varicose veins are one of the most common.

The measures that one can take to improve blood circulation include:

  • Weight loss, a smaller body requires fewer blood vessels, which improves blood circulation
  • Regular exercise, it also improves blood circulation
  • Avoid sitting or standing still for long periods. If the body does not move, blood circulation deteriorates
  • Avoid smoking
  • Maintain a healthy diet

When should you treat blood vessels that have suddenly become visible?

Normally, suddenly visible blood vessels are not dangerous, nor do they cause any discomfort or pain.

If the visible blood vessels are bluish, grow and begin to meander along the lower legs from the crease of the knee and can be felt on the outside, it is possible that varicose veins are taking shape.

If varicose veins are suspected, you can contact the Varicose Vein Clinics for a preliminary examination, no referral is required. After such a preliminary examination, one of our vascular surgeons will discuss with the patient various possibilities for possible treatment.
