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 uneventfully,
some may break off and travel through the blood vessels to the lungs, where they can cause life-threatening complica-
tions.
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.
Jet Lag & Motion Sickness
Jet lag is common when crossing more than five time zones; it results in insomnia, fatigue, malaise or nausea. To avoid jet
lag drink plenty of fluids (nonalcoholic) and eat light meals. Upon arrival, seek exposure to natural sunlight and readjust
your schedule. Some people find melatonin helpful.
Sedating antihistamines such as dimenhydrinate (Dramamine) or Prochlorperazine (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.
