However, it's now believed that if you have varicose veins, you may be at risk for Deep Venous Thrombosis (DVT), a potentially deadly clot that forms deep within the body.
However, Taiwanese researchers say they found that people with varicose veins had a 5.3-fold higher risk of deep vein thrombosis than those without varicose veins. While the condition has rarely been associated with serious health risks, previous studies have shown that patients with varicose veins have increased levels of inflammatory prothrombotic markers, which are thought to be associated with the pathophysiology of DVT, PE and PAD.
What's more, they were twice as prone to build up an aspiratory embolism - a clot which goes into the lungs and can be destructive.
People with varicose veins are at critical danger of building up a conceivably lethal blood clot, research recommends.

I didn't know how I was going to do. "I can't believe it, today was such a blur, I was just trying to make birdies". Lydia Ko has continued her middling start to the LPGA season with a 31st placing at the LPGA Thailand tournament.
Varicose veins are veins that have become enlarged and twisted, most commonly appearing in the legs and feet.
They included: 'Regardless of whether the relationship between varicose veins and DVT is causal or speaks to a typical arrangement of hazard factors requires additionally research'. They are generally caused by pregnancy or blood vessels weakening with age. The researchers also discovered 16,615 cases of peripheral artery disease among the varicose-vein group, compared with 9,709 cases for the adults without gnarled veins.
"Not much is known about varicose veins and the risk of other vascular diseases", Chang said.
Shyue-Luen Chang, MD, from the Vein Clinic, department of dermatology, Chang Gung Memorial Hospital and Chang Gung University College of Medicine in Taoyuan, Taiwan, and colleagues conducted a retrospective cohort study of participants aged at least 20 years without a history of DVT, PE or PAD in Taiwan's National Health Insurance program between 2001 and 2013. However, Chen noted that her team is now undertaking another study to better understand how those treatments could mitigate the risk of the 3 conditions. Researchers tracked more than 200,000 patients and said more studies are needed.
