DEEP VEIN THROMBOSIS (DVT)
Deep vein thrombosis (DVT) occurs when blood clots form in the legs during plane flights, chiefly because of prolonged immobility. The longer the flight, the greater the risk. Though most blood clots are rea-bsorbed uneventfully, some may break off and travel through the blood vessels to the lungs, where they may cause life-threatening complications. The chief symptom of DVT is swelling or pain of the foot, ankle or calf, usually on just 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, stretch your legs and contract the leg muscles while sitting, drink plenty of fluids, and avoid alcohol. Also, try to avoid tobacco before and after flights.
JET LAG & MOTION SICKNESS
]et lag is common when crossing more than five time zones; it 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 readjust your schedule (for meals, sleep etc) as soon as possible. Antihistamines such as dimenhydrinate (Dramamine) and meclizine (Antivert, Bon-ine) are usually the first choice for treating motion sickness. Their main side effect is drowsiness. A herbal alternative is ginger, which works like a charm for some people.
