Gastroenterologist Explains When to Get A Doppler Test For Varicose Veins

A viral video by gastroenterologist Dr Pal Manickam has renewed attention on varicose veins, with the doctor claiming that nearly 25–30% of Indians are affected by the condition. In the video, he urged people not to dismiss varicose veins as merely a cosmetic issue, warning that persistent symptoms such as sudden leg pain and swelling should be medically evaluated, including with a Doppler ultrasound when appropriate.

According to Dr Manickam, varicose veins develop when the valves inside leg veins become weak or damaged, causing blood to pool instead of flowing efficiently back to the heart. While many people experience visible, enlarged veins without serious complications, symptoms such as aching, heaviness, swelling, cramps or persistent discomfort may indicate the need for further medical assessment.

The doctor recommended a Doppler ultrasound for individuals experiencing concerning symptoms, as the non-invasive imaging test helps assess blood flow and detect problems such as venous insufficiency or blood clots. He emphasised that early diagnosis can help doctors determine the severity of the condition and decide whether conservative treatment or medical intervention is required.

Dr Manickam also cautioned that untreated varicose veins can progress over time. According to him, advanced stages may lead to skin discolouration, particularly darkening around the lower legs, followed by the development of venous ulcers. He further noted that, although uncommon, blood clots can form in affected veins and, in rare cases, lead to medical emergencies if they travel to other parts of the body.

Medical experts generally advise individuals to seek evaluation if they experience persistent leg swelling, sudden pain, skin changes, non-healing ulcers or symptoms suggestive of a blood clot. Risk factors for varicose veins include advancing age, prolonged standing, obesity, pregnancy, a family history of the condition and reduced physical activity.

While many cases can be managed through lifestyle measures such as regular exercise, maintaining a healthy weight, elevating the legs and wearing compression stockings, timely medical consultation remains important for persistent or worsening symptoms. Experts stress that a Doppler ultrasound can play a key role in diagnosing venous disorders early and helping prevent potential complications through appropriate treatment.
