What is vein weakness?
The veins in your legs have an important job: they carry blood back to your heart – uphill, against gravity. To help with this, there are small valves inside the veins that act like one-way doors.
If these valves don’t close properly, some blood can flow backwards and pool in the legs. Over time, this build-up can cause heaviness, tiredness, swelling, or tightness in the legs. Some people also experience cramps in the calves at night.
If vein weakness goes undetected, it can worsen and lead to varicose veins. The earlier it’s found, the easier it is to treat or slow down.
It’s a good idea to check how your veins are functioning if you:
- regularly have heavy, tired or swollen legs
- feel pressure in your legs after standing or sitting for a long time
- notice changes like swollen ankles or visible veins
- are unsure whether your symptoms come from a vein issue or fluid build-up
- have a family history of vein problems or developed symptoms after pregnancy
- want to prevent possible varicose veins early on
What happens during a vein check?
A special ultrasound technique is used to examine the veins in your legs. This shows in real time how the blood flows through the veins and whether the valves are working properly. The test is painless, takes only a few minutes, and delivers reliable results.
What happens after the test?
If vein weakness is detected, we will talk with you about the next steps: from preventive measures like compression stockings or exercise, to possible further treatment.
Our goal: relieve your symptoms, prevent varicose veins and improve your quality of life long term.

FAQ – Common questions about vein weakness
What is vein weakness?
Vein weakness – medically called chronic venous insufficiency – means the veins aren’t working properly and blood doesn’t flow well back to the heart. This can cause it to build up in the legs, leading to swelling, a feeling of pressure, or visible vein changes.
How can I recognize vein weakness?
Common signs include:
- heavy or tired legs (especially in the evening)
- swelling in the ankles or lower legs
- tightness, pressure or pulling pain
- visible, bulging veins
- skin changes like brown discoloration or rashes
What causes vein weakness?
Typical causes include:
- genetic predisposition
- sitting or standing jobs
- hormonal changes (e.g. during pregnancy)
- being overweight, lack of exercise, or vein inflammation
The risk increases with age.
How dangerous is chronic venous insufficiency?
If left untreated, it can lead to serious complications such as varicose veins, skin changes, vein inflammation, or — in the worst case — leg ulcers. That’s why early assessment is important.
How is vein weakness diagnosed?
The main test is a duplex ultrasound. This allows the doctor to check how the vein valves are working and see if blood is flowing backward. The test is painless and gives accurate results.
What treatment options are available?
Depending on the condition, treatment options include:
- compression therapy with special stockings
- exercise to improve blood return
- sclerotherapy, laser or surgery for varicose veins
- skin care for early changes
The goal is to reduce blood buildup and avoid long-term issues.
When should I have my veins checked?
If you regularly have heavy or swollen legs, or notice visible changes in your veins. It’s also helpful if vein problems run in your family or you’ve had a blood clot before.
How can I prevent vein weakness?
- move regularly (e.g. walking, cycling)
- avoid sitting or standing for long periods
- elevate your legs when possible
- maintain a healthy weight
- wear compression stockings if recommended
