Some risk factors for varicose veins and spider veins are out of your control. For example, a family history of either can raise your risk.
But some risk factors are modifiable.
“Although factors like age, genetics, and pregnancy cannot be changed, there are several lifestyle habits that may help reduce the risk of developing or worsening both spider veins and varicose veins by improving circulation and reducing pressure in the leg veins,” says Justin Ady, MD, an assistant professor of surgery and the medical director of the noninvasive vascular laboratory at Rutgers Robert Wood Johnson Medical School in New Brunswick, New Jersey.
Spider veins look like small, thin red or blue lines on your skin, while varicose veins are larger, more pronounced, and can look twisted, says Prakash Krishnan, MD, the director of endovascular interventions at the Mount Sinai Fuster Hospital’s cardiac catheterization laboratory in New York City. Varicose veins are often found on the insides of the thighs, the calf, or the back of the leg, but they can be found anywhere from your ankle to your groin. Spider veins typically occur anywhere on the legs or the face.
Both are caused by damaged valves in the veins and can cause pain, swelling, and other uncomfortable symptoms. If you notice either type, you should bring it up with your doctor to see if your symptoms require treatment. Your doctor may refer you to a specialist who can help.
“Although spider veins can occasionally cause mild discomfort, varicose veins are more likely to cause symptoms such as aching, heaviness, swelling, itching, or leg fatigue,” Dr. Ady says.
Experts explain five lifestyle factors that can worsen varicose and spider veins, and provide tips on how you can make adjustments to improve your vein health.
