Deep Vein Thrombosis
Deep vein thrombosis (DVT) occurs when blood clots form in the legs during long trips such as flights, chiefly because
of prolonged immobility. The longer the journey, the greater the risk. Though most blood clots are reabsorbed unevent-
fully, some may break off and travel through the blood vessels to the lungs, where they can cause life-threatening com-
plications.
The chief symptom of DVT is swelling or pain of the foot, ankle or calf, usually, but not always, on one side. When a
blood clot travels to the lungs, it may cause chest pain and difficulty in breathing. Travellers with any of these symptoms
should immediately seek medical attention.
To prevent the development of DVT on long flights you should walk about the cabin, perform isometric compressions
of the leg muscles (ie contract the leg muscles while sitting) and drink plenty of fluids (nonalcoholic). Those at higher
risk should speak with a doctor about extra preventive measures.
Jet Lag & Motion Sickness
Jet lag results in insomnia, fatigue, malaise or nausea. To avoid jet lag try drinking plenty of fluids (nonalcoholic) and
eating light meals. Upon arrival, seek exposure to natural sunlight and re-adjust your schedule.
Sedating antihistamines such as dimenhydrinate (Dramamine) and Prochlor-perazine (Phenergan) are usually the first
choice for treating motion sickness. Their main side effect is drowsiness. A herbal alternative is ginger. Scopolamine
patches are considered the most effective prevention.
