Each day may vary from this schedule as walking times differ with every group, some taking longer and other taking less, plus trail and lodge conditions need to be taken into account. The Guide in charge of your trek will alter the schedule if necessary as you will be walking to either Annapurna Base Camp, Everest B.C, or Annapurna Circuit at over 5000 m, you may feel Breathless and Lethargic for the first few days, perhaps even suffering mild headaches higher up.
If Symptoms become worse and you experience extreme Headaches and Nausea, inform your Guide so that he can ascertain whether you are suffering from Acute Altitude Sickness, and need to descend. As your "Annapurna" Trek takes you above 3500m, Trekking in Everest Schedule has been carefully designed to minimize the effects of altitude. We ascend slowly and surely allowing for safe Acclimatization with full relaxation.
Mild Headaches and Breathlessness are common at altitude and this is known as Benign Mountain Sickness which in itself is nothing to worry about. In rare cases, this may worsen so a close watch is kept on all trekkers by your Guide who is trained to recognize symptoms of Acute Mountain Sickness: severe Headaches, Nausea, Lethargy, and in extreme cases, ataxia and serious Breathlessness at rest. If any trekker shows any of these signs they will be evacuated to a lower, safe altitude immediately.
