The risk of deep vein thrombosis (DVT) is a harsh reality for millions of travellers each year.

“Blood clots, also known as deep vein thrombosis (DVT), occur when blood flow stops and collects in a vein, typically in the legs. If these clots reach the lungs, they can result in a life-threatening pulmonary embolism,” he added.

“Blood clots form when blood changes from a liquid to a gel-like state. This can happen for many reasons, but in the context of travel, it's mainly due to prolonged immobility. When we sit for long periods, blood flow in our legs slows down, making it easier for clots to form,” explained Dr Ghanwat.

Your risk level is influenced by the length of your journey and any existing factors that may increase your likelihood of blood clots.

Tips to Prevent Blood Clots While Travelling
Keep Moving
Make sure you undertake regular leg movement during long trips. Stretch your calves, flex your ankles, and try easy activities like extending your legs straight out and pushing your toes closer to you.
Wear Graduated Compression Stockings (GCS)
If you’re at higher risk for blood clots, ask your doctor about graduated compression stockings. These stockings can improve blood flow and reduce your risk. GCS with a pressure range of 15 to 30 mm Hg is recommended.
