How to Avoid Acute Mountain sickness in Everest Base Camp (EBC) Trekking?

May 7, 2020

AMS stands for Acute Mountain Sickness. It is a common condition that can affect trekkers and climbers at high altitudes, typically above 2500 meters above sea level. The lack of oxygen at higher altitudes can cause the body to react negatively, leading to symptoms of AMS.

The severity of AMS can vary, and it can affect anyone regardless of age, fitness level, or prior experience. Symptoms can range from mild to severe and may include headache, nausea, dizziness, fatigue, shortness of breath, loss of appetite, and trouble sleeping.

The risk of developing AMS increases with the rate of ascent, the altitude reached, and the individual’s susceptibility to the condition. The highest risk of AMS occurs at altitudes above 3500 meters, where the air pressure and oxygen levels are significantly lower.

It’s important to be aware of the symptoms of AMS and to take preventative measures, especially when trekking at high altitudes. This includes proper acclimatization, hydration, nutrition, and monitoring of symptoms. If symptoms of AMS persist or become severe, it’s important to seek medical attention and descend to a lower altitude until the symptoms subside.

Acute Mountain Sickness (AMS) is a common concern for anyone trekking at high altitudes, including the Everest Base Camp trek. The best way to avoid AMS is to prepare well and take appropriate measures during the trek.

• Proper Acclimatization: The most effective way to avoid AMS is to acclimatize properly. This means taking the time to adjust to higher altitudes, especially before reaching 3000 meters above sea level. A gradual ascent, taking frequent rest days, and staying hydrated can help the body adapt to the lower oxygen levels at higher elevations.
• Hydration and Nutrition: Proper hydration and nutrition are crucial in avoiding AMS. Drink plenty of water, tea, and other fluids to stay hydrated. It’s also important to eat well, with a balanced diet that includes carbohydrates, protein, and vegetables.
• Diamox: Diamox is a medication that can help prevent and treat AMS. It works by increasing the body’s oxygen uptake and speeding up the acclimatization process. It’s important to consult with a doctor before taking Diamox and to follow the recommended dosage.
• Avoid Alcohol and Smoking: Alcohol and smoking can make AMS worse. It’s important to avoid these substances during the trek to reduce the risk of developing AMS.
• Take it Slow: The Everest Base Camp trek is a challenging journey, and it’s important to take it slow. It’s better to trek at a steady pace and take plenty of rest breaks along the way. Rushing the trek and pushing oneself too hard can increase the risk of developing AMS.
• Monitor Symptoms: It’s important to monitor any symptoms of AMS and seek medical attention if necessary. Symptoms of AMS can include headache, nausea, dizziness, fatigue, and shortness of breath. If these symptoms persist or become severe, it’s important to stop trekking and seek medical attention.

In summary, avoiding AMS during the Everest Base Camp trek requires proper preparation, acclimatization, hydration, nutrition, and monitoring of symptoms. By following these guidelines, trekkers can enjoy the incredible beauty of the Himalayas without compromising their health and well-being.

Can you get altitude sickness at Everest Base Camp?

Yes, you can get altitude sickness at Everest Base Camp (EBC). EBC is located at an altitude of 5,364 meters (17,598 feet), which is considered a high altitude. Altitude sickness, also known as acute mountain sickness (AMS), is a common condition that occurs when you ascend to high altitudes too quickly without proper acclimatization. The symptoms of AMS include headaches, dizziness, nausea, and shortness of breath. The risk of AMS is high at EBC, but it can be prevented by acclimatizing properly, staying hydrated, eating a balanced diet, and avoiding alcohol and smoking.

Oxygen level at Everest base camp:

The oxygen level at Everest Base Camp (EBC) is much lower than at sea level due to the high altitude. The oxygen level at EBC is around 50% of what it is at sea level, which can make it difficult for the human body to function normally. This is why it’s important to acclimatize properly when trekking to EBC, to allow your body to adjust to the lower oxygen levels. Symptoms of altitude sickness can occur due to the lack of oxygen, and in severe cases, it can lead to life-threatening conditions like high altitude pulmonary edema (HAPE) or high altitude cerebral edema (HACE). It’s essential to take proper precautions and seek medical attention if you experience any symptoms of altitude sickness while trekking to EBC.

Acclimatization days at Namche Bazaar and Dingboche are mandatory when trekking to Everest Base Camp to prevent altitude sickness. The human body needs time to adjust to the low oxygen levels at higher altitudes, and acclimatization is the process of adapting to the reduced oxygen supply. The body produces more red blood cells to increase the oxygen-carrying capacity of the blood, which helps to alleviate the symptoms of altitude sickness.

Namche Bazaar, located at an altitude of 3,440 meters, is the gateway to the Khumbu region and a major stopover for trekkers en route to EBC. An acclimatization day at Namche Bazaar allows trekkers to adjust to the higher altitude, explore the local markets, and take in the beautiful mountain views.

Dingboche, located at an altitude of 4,410 meters, is the last permanent settlement before the final push to EBC. An acclimatization day at Dingboche allows trekkers to acclimatize to the altitude and explore the surrounding areas, including the stunning Ama Dablam mountain.

Both Namche Bazaar and Dingboche are important acclimatization points when trekking to EBC, and spending a day at each location helps trekkers to acclimatize properly and reduce the risk of altitude sickness.
