Can sport cause varicose veins?
Worried sport is giving you varicose veins? It is the opposite: exercise protects your veins. Here is the evidence and the best sports for your legs.
- No single cause of varicose veins has been identified.
- There is no clear evidence that sport causes varicose veins.
- Sport is generally good for vein health and circulation.
- Walking, swimming and cycling are especially recommended.
- With existing venous disease, discuss sport with a specialist.
Varicose veins are veins whose mechanism for returning blood to the heart against gravity is damaged: valves inside the vein open and close to stop blood flowing back down. When they no longer close properly, blood can flow back and pool, and over time visible varicose veins appear. They are a very common form of chronic venous insufficiency. But could sport be to blame?
The risk factors for varicose veins
So far, no single clear cause has been identified. Their development is worsened by many risk factors such as sex, age, excess weight, pregnancy and family history. Not everyone exposed to them develops varicose veins, though, which suggests genetic predisposition plays an important role.
Whatever the cause, a varicose vein can be treated without surgery: focused ultrasound (echotherapy) closes it with no incision.
Can sport actually cause varicose veins?
Some doctors suggest a possible link between certain sports, especially competitive ones, and varicose veins, but there are no clear studies to confirm it. Fundamentally, sport is recognised as good for vein health: activity stimulates circulation, counters blood pooling in the legs and helps blood return to the heart, reducing the pressure on the vein walls.
Which sports are best for your veins?
With venous insufficiency, the best sports are the ones that keep your legs moving and support the calf muscles that help pump blood back up. Done gently and regularly, they ease the pressure in the veins rather than adding to it.
Some sports are particularly suited to venous problems because they keep the legs moving:
| Sport | Why it helps |
|---|---|
| Running and walking | Strengthen the leg muscles that support vein function. |
| Swimming | Gentle: the water unloads the legs, and cool water contracts the veins. |
| Cycling | Helps the veins pump blood; keep to flat routes and an upright posture. |
| Cross-country skiing and dancing | Keep the legs moving and benefit vein health. |

Can sport cause varicose veins?
There is no clear evidence that it does. Some doctors suggest a link with competitive sport, but overall sport is recognised as good for vein health.
Is exercise good or bad for varicose veins?
Good. Activity stimulates circulation, counters blood pooling in the legs and helps blood return to the heart, reducing pressure on the vein walls.
Which sports are best with varicose veins?
Gentle, leg-moving sports such as walking, running, swimming and cycling. Cross-country skiing and dancing also help.
Is cycling safe for varicose veins?
Yes, on fairly flat routes and with an upright posture, pedalling with the flat of the foot to avoid congestion around the pelvis.
Should I exercise if I already have varicose veins?
Usually yes, but discuss the right activities with a specialist first.
