Causes of Altitude Sickness

Annapurna Circuit Trek

Clearly there is no one particular reason for altitude sickness as sometimes the sickness can arouse due to the low oxygen in the air. Turns out that it also happens after your body refuses to adapt with the temperature placed at these altitudes. Some of the causes of Annapurna Circuit altitude sickness are as follows.

1. High Altitude

Not always but high altitude is a major cause behind the acute mountain sickness on Annapurna Circuit Trek for most of the time. It occurs when you ascend to the utmost height too quickly and stay there for too long without taking rest.

With no contradiction, altitude sickness can happen from as low as 1500-2500 meters height along with the side effect of climate. But in most cases, people suffer from altitude sickness shortly after they are exposed to extreme altitudes.

That means when you reach at or greater than 5500 meters height, there’s more chances for you to have a severe effect of altitude sickness. The rule is simple here and it’s that the more you gather speed at higher altitude, the more you are likely to get affected.

And in case of Annapurna Circuit Trek, you have to reach up to 5416m which is a lot to ask. To add more stress, you’ll have to walk for as many as two weeks which weakens the physical strength. This comes on strong with the absence of oxygen in the air at high altitude.

2. Change in Weather

Weather Change is another reason for altitude sickness during Annapurna Circuit Trek. To put it in a simple way, unforeseeable weather at high altitude in Annapurna Circuit can severely affect your health.

You can be enjoying mild weather a few hours ago and at the very next moment, it can get bitterly cold. In such a situation, your body could find it difficult in adapting with the weather and climate of the place.

Just in case, it refuses to adjust with the weather, you’re likely to put up with the symptoms of altitude sickness which can get worse in absence of proper medications.

3. Oxygen amount at high Elevation

It’s a fact that the presence of oxygen at higher altitude is seemingly low and that it causes problems in breathing. This is perhaps the reason for why many trekkers at Annapurna Circuit develop altitude sickness since they have to make it up to Thorong La Pass.

You might not know but Thorong La is the highest point for Annapurna Circuit Trek and it lies at an elevation of 5416 meters. Hence, it’s not surprising why so many hikers on the trek struggle from shortness of breath as more and more they ascend higher altitude.

Annapurna Circuit Trek In October

Acute mountain sickness is pretty much evident during long-distance treks. And in Annapurna Circuit altitude sickness is even more apparent as one has to constantly ascend high altitude and that too for a long time. This makes it tough for a human body to adapt to the changing temperature and low oxygen in a short little time.

And that’s why altitude acclimatization is important as it helps you adjust with the temperature and climate. As for Annapurna Circuit Trek, there is at least a day scheduled for altitude acclimatization.

It is too important that you pay attention to what your body asks for. With the gradual changes in altitude, your body could be struggling to adapt with the environment. So every time you climb high altitude or descend, make sure to have proper rest.

It’s even better if you escape dramatic gains and try not to achieve more of it in a single day. If you start developing the signs of acute mountain sickness time and again, just stop ascending immediately and take medicines.

Also make sure that you don’t continue trekking until all your symptoms disappear and you regain your physical strength.
