Altitude Sickness and Annapurna Base Camp

At high altitudes, the body sometimes has trouble adjusting to less oxygen, which can cause symptoms like headaches, sickness, dizziness, and breathing problems. Usually, people can climb to moderate heights without issues, but people with a higher chance of getting AMS, like people with heart or lung issues, may have more risk of getting it.

The Annapurna Base Camp trek, a renowned haven for hikers and trekkers, draws thousands of enthusiasts annually with its panoramic vistas of the Annapurna mountain range and its surrounding panoramas. Despite its undeniable charm, the altitude of the base camp necessitates that trekkers be prepared for the risk of altitude sickness. Proper acclimatization and preventive measures are crucial for preventing AMS, as the condition can prove difficult if ignored. Hiking enthusiasts can implement various tactics to reduce the likelihood of acquiring altitude sickness. One of the most productive strategies is increasing elevation step-by-step, providing sufficient body time to acclimate to the reduced oxygen concentration. Additionally, maintaining proper hydration levels is essential, as dehydration can boost the effects of Acute Mountain Sickness (AMS). Other preventative measures include abstaining from alcohol and tobacco, obtaining ample rest, and consuming a carbohydrate diet.

The elevation of Annapurna Base Camp is challenging to many trekkers, while it is considered easy to moderate for experienced ones. If you are not okay with the rise in altitude and your body is not flexible to high altitudes and their environment, you will probably have a problem. It might come as altitude sickness or any other form of illness. So, preparing yourself before going on the Annapurna Base Camp trek is highly recommended.

Altitude Sickness At different altitudes in Annapurna Base Camp

Altitude Sickness is no strange name for a high-altitude climbing journey. Since Annapurna Base Camp also lies at a high altitude, no one knows if your body can adjust to that environment. That’s why we recommend proper preparations.  

You need not worry about any altitude-related issues in your journey from the picturesque Nayapul, where the elevation is a mere 1070 meters. 

However, you may feel slight discomfort due to the altitude as you make your way up to the panoramic Ghorepani, standing at a striking 2874 meters, and the breathtaking Poonhill, towering at 3200 meters. But be at ease, as the height of these elevations poses no threat of altitude sickness. Likewise, the elevation of Chhomrong at 2160 meters and Dobhan at 2500 meters also pose no threat of altitude illness.

As you reach the apex of Deurali, located at an altitude of 3230 meters, the trekkers need to remain alert for any symptoms of altitude sickness. This height demands extra caution and care. The beginning of Acute Mountain Sickness (AMS) is common at an elevation of approximately 2,400 meters, or 8,000 feet. Nevertheless, the danger of developing AMS soon escalates as one ascends to greater heights.

Altitude sickness might come in various forms: Acute Altitude Sickness, High Altitude Pulmonary Edema (HAPE), and High Altitude Cerebral Edema (HACE).

Acute Altitude Sickness generally features symptoms like dizziness, insomnia, nausea, and vomiting. HAPE impacts your lungs, making breathing hard to breathe and decreasing heartbeats. In the same way, HACE is regarded as the most dangerous type of altitude sickness, which affects your cognitive ability as it forms fluid in the brain system.

Considering these things, you should plan your trekking schedule and safety measures accordingly. This will help you conquer the Annapurna Base Camp trek.
