Medication shops are few on trekking routes. Therefore,it is best to carry first aid and read about the possible problems before hand. On the Everest Base Camp route at Pheriche and on the Annapurna Circuit at Manang, there are clinics operated by the Himalayan Rescue Association that specializes in treating trekker's health problems. These clinics are open during the main trekking seasons.

While on treks, the following problems could occer:

1. Upset stomach, often caused by change in diet or contaminated food and water is a common ailement. To avoid it, one should pay particular attention to hygiene and quality of food and drinks.

2. Cough, cold, sore throats, common in the dry mountain air can lead to chest infection. Sore throats can best be avoided by attempting not to breathe cold air directly through mouth. Smoking should also be avoided.

3. Joint muscle strains, foot problems and blisters are other dindraces for trekkers. Wearing good footwear will go a long way in avoiding these problems. For sprains and strains, apply cold water to reduce swelling and support the joing with crepe bandage.

4. Acute Mountain Sickness(AMS) is a fatal sickness caused by random altitude ascension. Therefore, climbers ascending 3000 meters or above should acquire sound knowledge of proper acclimatization processes. Symptoms of AMS include headache, loss of appetite, swelling of limbs, dizziness, difficulty in sleeping, irregular breathing, nausea and unusal weariness. Maitaining good fluid intake helps combat altitude sickness and hurried descent or evacuation to lower altitude is the only best cure.
