Altitude Sickness

When you travel to Nepal, especially to the mountains and trekking regions, a common challenge that many travelers face is altitude sickness. Also known as Acute Mountain Sickness (AMS), this happens when you go to higher altitudes quickly, and your body doesn’t have enough time to adjust to the thinner air.

At sea level, the air is full of oxygen, and its body works normally. But when you go above 2,500 meters, the oxygen level gets lower. The higher you go, the less oxygen your body receives. This sudden change pressures your body, especially your lungs and brain, leading to symptoms of altitude sickness.

Symptoms of altitude sickness

Altitude Sickness can affect someone, however strong, young, or fit. The most common symptoms include:

• Headache
• Nausea or vomiting
• Loss of appetite
• Trouble sleeping
• Dizziness or lightheadedness
• Shortness of breath, especially while walking
• Tiredness and lack of energy

In severe cases, people may also experience swelling of hands and feet, confusion, or difficulty walking straight. If ignored, it can lead to life-threatening conditions such as high altitude pulmonary edema (HAPE) or high altitude brain edema (HACE).

How to Avoid Altitude Sickness?

The good news is that altitude sickness can be avoided by following some simple tips:

• Slowly climb – Don’t run to higher places. Your body needs time to adjust. At Morning Star Treks, we project itineraries with enough rest days for acclimatization.
• Remove days of rest – Pass extra nights at certain altitudes so that your body gets used to the thinner air before rising more.
• Keep hydrated – drink plenty of water, at least 3 to 4 liters per day. Avoid alcohol and smoking as they can make the situation worse.
• Eat light and nutritious meals – suitable foods provide body energy to better adapt to high altitudes.
• Listen to your body – if you feel bad, stop climbing louder. Rest, recover, and continue if you feel better.
• Use medications, if necessary – some trekkers take medications like Diamox to prevent or reduce symptoms. Always consult your doctor before taking a medicine.
• Traveling with experienced guides – Our professional guides in Morning Star Treks are trained to recognize symptoms of altitude sickness. They will ensure that you are safe and know what to do if problems arise.

What to Do If You Get Altitude Sickness?

If you notice symptoms, don’t ignore them. Here are some important steps to be taken:

• Stop rising louder – don’t continue at a higher altitude if you already feel sick.
• Rest and recover – Stay where you are, relax, and let your body fit.
• Go down, if necessary – if the symptoms get worse, the best cure is to descend to a lower altitude. Even a drop of 500 to 1,000 meters can make a big difference.
• Get medical help – In case of serious conditions such as HAPE or HACE, immediate medical attention and oxygen support are required.
