Deep-vein thrombosis (The Sunday Times, 23 April 2006)

Q. I am flying long-haul on holiday this year. Is there anything I can do to reduce the risk of deep-vein thrombosis (DVT)?



A. The risk of developing DVT when you are cramped and immobile is well documented, but recent research published in The Lancet highlighted the fact that low cabin pressure and lack of oxygen on planes may also contribute to the development of blood clots in susceptible individuals.

To promote healthy circulation, I suggest that, before the flight, you eat plenty of ginger and garlic. You should also favour foods rich in essential fatty acids such as oily fish (herring and mackerel) and nuts and seeds such as flax and walnuts, as these also improve blood flow.

I would also recommend Vascular Guard (£22.95 for 30 capsules, from Biocare; 0121 433 3727), which contains natural vitamin E, lycopene and antioxidant extracts of pine bark and grapeseed to enhance blood- vessel function, and bilberry to maintain blood flow to the extremities. Take one capsule twice daily a few weeks before the flight, and for a week after you have returned home.

Alternatively, the herb ginkgo biloba has been used for thousands of years as an aid to circulation. A.Vogel Organic fresh herb tincture of ginkgo biloba costs £7.99 for 50ml (free p&p, from Bioforce; 01294 277344). Add 30 drops to a bottle of water and drink throughout the day of your flight. Finally, travel in loose-fitting clothes and shoes, drink plenty of water and follow the in-flight exercises suggested by the airline.
