Can obesity and overweight result in the outbreak of varicose veins?
Is your weight behind your varicose veins? Obesity is a real risk factor, it raises pressure in the leg veins and even makes the veins harder to diagnose.
- Obesity is a recognised risk factor for varicose veins.
- Excess abdominal weight raises pressure in the leg veins.
- The link is especially strong in women, including after menopause.
- Extra weight makes varicose veins harder to spot and diagnose.
- Late diagnosis raises the risk of complications like ulcers.
Varicose veins are blood vessels that have lost the ability to carry blood back to the heart, a condition called chronic venous disease. They may be a simple cosmetic concern, but they can also cause real health problems. Is being overweight one of the reasons they appear?
Does obesity cause varicose veins?
The causes of varicose veins are multifactorial, but several risk factors come up again and again: gender, age, number of pregnancies, family history, and overweight and obesity. Studies show that, especially in women, obesity and low physical activity are more common in those who develop varicose veins, and that venous disease tends to be more severe in people who are overweight.
Is it only a risk factor for women?
The connection between weight and venous disease appears stronger in women than in men. One study found that a higher BMI was significantly linked with a greater risk of varicose veins in postmenopausal women.
Whatever the cause, a varicose vein can be treated without surgery: focused ultrasound (echotherapy) closes it with no incision.
How can excess weight cause varicose veins?
Excess weight raises pressure in the abdomen, which pushes up the pressure in the leg veins and promotes venous disease. Fatty and fibrous tissue around the veins can also disturb circulation and slow blood flow, favouring the stasis that leads to varicose veins.
In practice, this shows up in a few ways:
| How excess weight affects the veins | Effect |
|---|---|
| Higher abdominal pressure | Raises pressure in the leg veins, promoting the disease. |
| Disturbed blood flow | Fatty tissue around the veins slows circulation and favours pooling. |
| Harder diagnosis | Veins sit deeper, so varicose veins are spotted and treated later. |
The hidden varicose vein problem
Excess weight also makes varicose veins harder to spot. In people of average weight the twisted veins are easy to see, but in heavier patients they often show no visible signs, so they see a doctor later, at greater risk of complications and leg ulcers. Diagnosis is also less precise: the duplex ultrasound used to map the veins works less well when they lie deeper in the tissue, which can complicate treatment. Age and other factors add to the picture.

Questions fréquentes
Can being overweight cause varicose veins?
Obesity is a recognised risk factor. Excess abdominal weight raises pressure in the leg veins and can promote and worsen venous disease.
Why does obesity affect the veins?
Higher abdominal pressure pushes up leg-vein pressure, and fatty tissue around the veins can disturb circulation and slow blood flow.
Is the link stronger in women?
Yes. Studies show a strong connection in women, and a higher BMI is significantly linked with varicose veins in postmenopausal women.
Why are varicose veins harder to diagnose in overweight patients?
The veins lie deeper under the tissue, so they are less visible and duplex ultrasound is less precise, often delaying diagnosis.
Does losing weight help varicose veins?
It reduces a key risk factor and eases pressure on the veins, but existing varicose veins still need treatment to close them.
