High Altitude Sickness

Trekking in Nepal need not be considered risky affair as far as your health is concerned. Nevertheless, preventive measures such as a through medical check up and inoculations before you start trekking can save you from unexpected hazards. Since the remote places of Nepal are not supplied with necessities that are essential for modern medical facilities and as the rescue and evacuation are measured in days, it is imperative to make a comprehensive first aid box consisting of basic drugs and accessories as part of the paraphernalia for trekking. Modern dentristry is unknown in the hill of Nepal so it is advised to have a checkup before departure from home. Tooth fillings, sometimes loosen in cold temperatures and high altitudes, so it is recommended to have them checked. Travelers are requested to bring medicine prescribed by their doctor at home. Common medicine for stomach problems, headache, and malaria is available in Kathmandu. Medicine is usually not available in remote areas. So necessary medicine is advisable to carry with you. Before going to Nepal, it is advised to get injections against typhoid, meningitis and hepatitis.
