Have you noticed recently that the veins on your legs are becoming more visible? Perhaps your visible veins are looking darker or are now raised above the skin. What about leg swelling, heaviness, achiness, itching, tingling, or cramps? If these issues have been going on for a while, you might have noticed areas of skin discoloration or ulceration.

There are a variety of potential causes for visible veins, but the above symptoms can indicate underlying vein disease. Vein disease occurs when tiny vein valves in your legs malfunction and cause blood to pool in the lower extremities, leading to varicose veins. This can lead to varicose veins, spider veins, restless leg syndrome, and other potentially dangerous health conditions. When you have vein disease, you are also at higher risk for blood clots and venous ulcers.

Below, we talk about what it means to have veins showing through skin or veins that rise above the skin’s surface. The good news is that visible veins are not always cause for concern. They can be indicators of a healthy Body Mass Index (BMI), regular exercise, or even hot weather.

We always recommend visiting a vein specialist to evaluate any visible veins of concern. Before your appointment, here’s what you should know about visible veins on legs and other areas of the body.

Why Are My Veins So Visible?

When it comes to establishing the cause of your visible veins, discuss your genetics, lifestyle, and environment with your doctor. Many of these factors influence overall vein health.

Some potential causes of visible veins include:

  • Exercise: If you notice visible veins when you exercise, this may be a sign your cardiovascular system is working properly. In particular, weight lifting often results in protruding veins due to low BMI.
  • Skin: Individuals with fair skin and hair tend to have more visible veins.
  • Age: Skin becomes thinner over time and can contribute to veins showing through the skin. The loss of certain fat as we age also allows veins to further protrude.
  • Weight: Because excess weight can place additional strain on your veins, being overweight or obese can cause vein issues.
  • Family History: If you have close relatives with visible veins, you are more likely to develop them.
  • Hormones: Did you know that hormones can affect your vein health? Hormonal imbalances due to pregnancy, menopause, or other health conditions can result in visible veins. Pregnancy also involves increased blood volume, which leads to the expansion of blood vessels. In this case, visible veins usually resolve after giving birth.
  • Weather: Are your veins showing more in the summer? Heat can cause veins to enlarge. It also makes your vascular system work harder overall, causing veins to appear more prominent.
  • Prolonged Sitting or Standing: Individuals on their feet or sitting throughout the day are more likely to develop visible veins.

If you believe your visible veins are due to more than just the factors above, you may want to schedule an appointment for further evaluation by a vein specialist. They can help determine your best treatment options.

Frequently Asked Questions (FAQs) About Visible Veins

Why are my veins showing?

This is similar to the questions, What does it mean if your veins are showing, and What causes veins to be more visible? Basically, genetics, lifestyle, and environmental influences can cause veins to show through the skin or visibly protrude above it. To determine what is going on with your veins, we recommend consulting your doctor or a vein specialist.

Why are my veins so visible all of the sudden?

This can be a sign of something serious. If you notice any sudden changes in your veins, there may be a blood clot involved. Please seek care immediately, this is considered a medical emergency.

Why are my veins so visible on my hands?

Although the lower extremities are a common site for visible veins, they can also occur elsewhere on the body. All of the same genetic, lifestyle, and environmental factors discussed above can impact the health of veins in your hands.

Are veins popping out of arms good or bad?

It really depends. If your veins are protruding due to regular exercise, low body fat, and good muscle tone, this is probably good. However, problematic veins can occur in your arms, wrists, hands, and many other regions of the body.

If blood is red, why are my veins different colors?

There’s no doubt that this is a confusing topic. Take a detailed look at the reasons in our popular blog post, Why Are My Veins Blue and Green?

When to Worry About Visible Veins

If you have visible veins and are at risk for developing vein disease, talk to your doctor about regular monitoring. You are considered high-risk if you have a family history of varicose veins, a job where you stand or sit for prolonged periods of time, or are over age 50, female, obese/overweight, or pregnant.

We suggest that you remain on the lookout for:

Spider Veins

Spider veins are tiny, colorful veins that usually appear on the legs or face. They develop in a spider web pattern and may appear red, purple, or blue. Although usually painless, they are an early sign of vein disease.

Varicose Veins

Varicose veins are enlarged, dark blue, visible veins that protrude above your skin’s surface. Although sometimes considered merely cosmetic, they can cause significant pain and discomfort. Common varicose vein symptoms include heavy legs, swelling, itching, burning, and pain relief when legs are elevated. Varicose veins develop due to underlying vein disease.

Blood Clots

Did you know that visible veins can be caused by, or develop into, a blood clot? The presence of a blood clot can be life-threatening and requires immediate medical attention. When left untreated, a blood clot can break off and cause a pulmonary embolism.

There are two main types of blood clots: Superficial Thrombophlebitis (ST) and Deep Vein Thrombosis (DVT). Common symptoms of both include leg pain, redness, swelling, tenderness, warmth, and cramping. Symptoms are usually located in only one leg.

Skin Changes

Along with causing visible veins, vein disease can lead to a range of related skin issues. These include discoloration, itching, burning, rashes, and venous ulcers. Venous ulcers are open, non-healing wounds that occur on the legs near varicose veins. They are a sign of advanced vein disease and can put you at risk for serious skin or blood infections.

Minimally-Invasive Treatment for Unhealthy Visible Veins

Whether you are concerned about unsightly veins showing through skin or painful varicose veins that limit activities, there’s help available. Get started by asking your doctor, “why are my veins so visible?” If vein disease is behind your visible veins, a variety of minimally invasive treatment options exist.

At USA Vein Clinics, our specialists offer state-of-the-art, office-based treatment. All of our techniques aim to close off malfunctioning veins and reroute blood flow to surrounding, healthy ones instead. Most treatments take between 15 and 30 minutes and allow you to leave immediately afterward.

If this all sounds overwhelming, don’t worry, we are here to help you to develop an individualized plan of care. Together, we may decide on one or more of the following:

Treatment for varicose or spider veins - doctor meeting with patient at vein clinic

Endovenous Laser Treatment

During Endovenous Laser Treatment (EVLT), a specialist makes a tiny incision in the skin using a small laser fiber catheter. Ultrasound is used to precisely position the laser, which is heated up to close off the diseased vein. EVLT can treat varicose veins of any size that are located close to the surface of the skin.


ClariVein treats varicose or spider veins without the use of laser energy. It is a catheter-based treatment that combines mechanical and chemical methods to treat malfunctioning veins.


Varithena is a foam-based treatment designed to treat diseased veins. It is often used to collapse varicose veins located in the Great Saphenous Vein (GSV) or surrounding region.

Ultrasound-Guided Sclerotherapy

Ultrasound-Guided Sclerotherapy involves using ultrasound imaging to inject a sclerosant solution into problematic veins. This irritates the vessel’s walls and causes it to collapse and seal off. After treatment, the diseased vein tissue is naturally absorbed by the body.

Visual Sclerotherapy

Similar to Ultrasound-Guided Sclerotherapy, Visual Sclerotherapy involves sclerosant injections. It has minimal side effects, and is used to treat spider veins located near the surface of the skin.
