At altitudes higher than 2500m, one begins turning into increasingly prone to AMS. This complete trek is above that altitude.

Causes of Altitude Sickness on EBC Trek
I personally am partly accountable for not acclimatizing properly. Within the itinerary that I discussed above, you’d have seen that there are two days specifically stored for acclimatization. The purpose to note is that there are not any relaxation days the place you simply sleep or laze, which is what I principally did. What needs to be carried out is actually an age-old principle which even climbers comply with on Mt.Everest and different extreme peaks – which is – CLIMB HIGH, SLEEP LOW.
On the acclimatization days at Namche and Dingboche, you’re imagined to do brief day hikes to larger places and come again right down to your teahouse to relaxation. This prepares the physique for the subsequent day’s trek. From Namche (3440m) there’s a fantastic trek to Everest View Lodge at 3880 meters, and from Dingboche, there is a comparable hike to a better elevation. What I did was principally to laze and chill out at the teahouse. Reality is these day hikes can be completed by lunchtime and you’ll have all the day to chill out. Had I finished that, I consider I’ll have acclimatized higher.
AMS Susceptible Areas on EBC Trek
Given under are a couple of sections on the trek where due to additional strain on the system, AMS is probably going. These are additionally the robust sections of the trek, and if you surpass these sections, the endorphin pump and its adjuvant exhilaration that you will feel after conquering these sections are absolutely unmatched and can stay with you for a lifetime!
- Day 2: The section from Monjo to Namche. One steep climb gaining almost 700 meters in 4 hours walk – an unbelievable feeling once you walk into Namche.

Tips on how to Keep away from Altitude Sickness on Everest Base Camp
Under are a number of ideas on learn how to forestall altitude sickness on Everest Base Camp Trail.
Keep away from Exerting Yourself
The first principle is, in fact, listening to your physique. Do not hesitate to halt. I ended once I felt the headache. I had stored buffer days for the same function. Avoid a crammed itinerary the place you’re pressured to push on and ignore the warnings that your physique provides you. The same night time whereas I used to be at dinner on the teahouse in Thugla, I noticed two incidences the place trekkers who had gone greater have been carried down and seeing the nervousness on their companions faces I used to be grateful to have rested. It isn’t a pleasing experience the place Sherpas have to carry you right down to the Himalayan Rescue Affiliation (HRA) middle at Pheriche particularly within the night time. That too when it’s utterly preventable. Keep in mind, you are not climbing Mt.Everest.
You’re solely and easily trekking to its base camp. AMS on this trek is preventable and most significantly, controllable. Only if you push yourself unnecessarily is when things get a bit of ugly.
Don’t Overestimate Your self
Drawback arises when individuals think of too excessive of themselves and try to exhibit. Keep in mind, this isn’t the place to play macho and ignore what your body is telling you. All the time keep in mind the area you have been standing in, respect the mountain you have been dealing with and don’t overestimate your self. You bought to stop on the first signal of altitude sickness and not try to push yourself even further. The upper you go and the more you exert your self, the worst it’ll get for you.
Never try to Disguise your Situation
The very first thing I did once I suffered from AMS was to inform my tour information and that’s what it is best to do too. Don’t lie or disguise about your situation even if it means delaying all the group with you. Keep in mind this is what you will have paid them the cash for and the opinion of the group isn’t extra essential than your life and health. In the event that they need to frown upon you then so be it but all the time be vocal about how you have been feeling and if one thing was bothering you.
Loosen up A lot
Go at your personal pace. Do not really feel compelled to catch up once you really feel bodily exhausted. That is why I feel you need to do this trek with individuals you recognize – like your close group of associates or household, or your companion or even solo, somewhat than a gaggle of unknown individuals, organized by an organization. Because within the latter state of affairs, one is pressured to push oneself because of the psychological strain of not eager to delay others.
That is also the rationale why I name this trek a type of meditation. I consider mediation is a state of higher awareness. In this trek, you will have to concentrate on your system and control your respiration. You’re answerable for your system. Two weeks of this can deliver a few change in perspective!
Chose the appropriate Group
This shall be in continuation with the point I mentioned above, that whenever you journey with a tour group or agency, you’ll be mentally pressurized to maintain up even in case you have been drained and needed to rest. It will happen even more should you have been with the incorrect set of individuals and guides. A fast search on Google provides you with info on a whole lot of tour businesses arranging the trek annually and claiming to be one of the best.
However you bought to just remember to do your analysis properly and discover out extra about what sort of providers they’re providing, info on medical insurance coverage, some historical past on the guides that might be accompanying and most significantly, what their itinerary is going to be. Never opt for a rushed itinerary and make sure that you inform the company about your degree of trekking expertise to allow them to put you with the correct group.
An Very best EBC Trek Itinerary to avoid AMS
The itinerary I adopted for the trek is as talked about under. It is a complete of 17 days journey and I used to be nonetheless hit by altitude illness in between.

The second preventive step is Tablet Diamox. It makes the blood barely acidic by throwing out bicarbonate by way of urine and to compensate for this acidity, respiration is made quicker and deeper. This, in flip, improves blood oxygenation and hence helps forestall AMS. I started on a 125mg twice every day foundation from the day I walked to Namche. Took it every day until the day of my descent from Base Camp.
There isn’t a method of telling how much this helped but that is the routine I adopted. You’re free to keep away from this and acclimatize naturally. The truth is, the subsequent time I do that trek, that is what my plan is. There are other generally used pure regimens like garlic soup, which I’ve observed does have an effect in enhancing the best way you are feeling after a full day’s trek. Nevertheless, I’m not outfitted to remark on the way it works.
Diamox is usually preventive relatively than curative. However on the day I had that splitting headache, I did take a 250mg dose. Together with painkillers in fact. In case you are allergic to sulpha medicine kindly keep away from Diamox. And seek the advice of your doctor earlier than going on a course of Diamox, especially if are on any common medicine.
Trek Excessive and Sleep Low
The third and remaining step is following the precept of trek excessive and sleep low, on the lively acclimatization days. Do take this critically as it has been designed that means for a objective.
Don’t Smoke or Drink
The worst thing you can do to yourself up there’s to bask in smoking and consuming. The impact it’ll have on you at such high altitude shall be fairly drastic and should even ship you residence packing. On account of low oxygen levels, alcohol and cigarettes are an enormous NO on EBC trek. You will simply be gasping for breath, feel dehydrated and weaker; and should find it even unattainable to proceed any further on the trek.
Maintain Your self Hydrated
You have to maintain yourself nicely hydrated at all times. Drink plenty of water at regular intervals. Being in such chilly climate might end in you not feeling thirsty that always but you got to make sure that you are intaking no less than 5 kilometers of water day by day.
And by that, I imply to get your self ready for the trek ahead. Trekking to Everest Base Camp shouldn’t be going to be a stroll within the park and you understand it. You bought to get your body prepared for hours of walking in such harsh weather. Hit a fitness center or start operating outdoors day-after-day. Your train schedule should embrace jogging or strolling in hilly areas. If that isn’t an choice than stay on a treadmill at the highest elevation for an hour day-after-day. Aside from making your legs and physique stronger, it is going to also practice your coronary heart to breathe normally even in low oxygen levels and skinny air.
