Altitude Sickness on Manaslu Circuit Trek

Altitude sickness is a common challenge for trekkers on high-altitude trails like the Manaslu Circuit. It can cause symptoms like headaches, dizziness, and nausea, making it essential to prepare and take preventive measures. 

The Manaslu Circuit Trek starts at an altitude of approximately 800 meters (2,625 feet) and involves a gradual daily ascent of around 300 to 400 meters (984 to 1,312 feet). After reaching 3,000 meters (9,843 feet), two acclimatization days (Samagaun and Samdo) are included to help you adjust to the altitude. 

Compared to other popular treks like Everest, the likelihood of experiencing altitude sickness is relatively low. However, it is still essential to follow basic precautions, such as staying hydrated, ascending slowly, and allowing your body sufficient time to acclimatize, to ensure a safe and enjoyable trekking experience.

In this article, we’ll discuss practical tips to avoid altitude sickness on the Manaslu Circuit Trek and ensure a safe and enjoyable journey. With proper planning, acclimatization, and the right techniques, you can minimize the risks and make the most of your adventure.

What is Altitude Sickness? Causes and Symptoms

Altitude sickness happens when your body struggles to adapt to the lower oxygen levels at high altitudes. It’s a common issue for trekkers on the Manaslu Circuit, where elevations can go above 5,000 meters(16404 feet). Knowing what altitude sickness is on the Manaslu Circuit and its symptoms can help you stay safe during your trek.

Types of Altitude Sickness

• Acute Mountain Sickness (AMS): The most common type, causing headaches, nausea, dizziness, and tiredness. It usually starts at altitudes above 2,500 meters.
• High Altitude Pulmonary Edema (HAPE): A more serious condition where fluid builds up in the lungs, making it hard to breathe. Symptoms include chest tightness and coughing.
• High Altitude Cerebral Edema (HACE): A dangerous condition where fluid collects in the brain, causing confusion, severe headaches, and difficulty walking.

Common Symptoms of Altitude Sickness

• Headache, dizziness, and feeling very tired.
• Loss of appetite and nausea.
• Trouble sleeping and shortness of breath.
• Serious symptoms like confusion or extreme breathlessness require immediate descent and medical help.

Recognizing the symptoms of altitude sickness and taking action early can prevent it from becoming serious. Proper preparation, pacing, and acclimatization are key to staying healthy on the Manaslu Circuit Trek. 

Why Acclimatization is Essential on the Manaslu Circuit

Acclimatization is the process of helping your body adjust to the lower oxygen levels at high altitudes. It is very important for avoiding altitude sickness, which can make you feel unwell or even lead to serious health problems. Understanding the importance of acclimatization on the Manaslu Circuit Trek and following the right steps will help you stay safe.

What is Acclimatization and Why is it Important?

• At high altitudes, there is less oxygen in the air, and your body needs time to get used to it.
• Acclimatization allows your body to produce more red blood cells to carry oxygen better.
• Without proper acclimatization, you might experience symptoms like headaches, nausea, and feeling very tired.

Suggested Acclimatization Schedule for the Manaslu Circuit Trek

• Rest Days: Take at least one or two rest days during the trek, especially in places like Samagaun (3,520 meters). These days give your body time to adjust.
• Slow Ascent: Avoid climbing too quickly. Keep your elevation gain to about 300-500 meters per day once you are above 3,000 meters.

Tips for Acclimatization

• Drink plenty of water to stay hydrated.
• Avoid alcohol and caffeine as they can dehydrate your body.
• Walk at a steady pace and don’t push yourself too hard.
• Follow the “climb high, sleep low” rule: hike to higher altitudes during the day but sleep at a lower altitude.

By following these simple best practices for acclimatization, you can reduce the risk of altitude sickness and enjoy your trek on the Manaslu Circuit. 

Practical Tips to Avoid Altitude Sickness on the Manaslu Circuit Trek

Altitude sickness is a common challenge on high-altitude treks like the Manaslu Circuit. Following these tips for successful acclimatization can help you stay healthy and enjoy the trek. Here’s how to prevent altitude sickness on the Manaslu Circuit Trek.

1. Ascend Gradually

The best way to prevent altitude sickness is to climb slowly. Avoid gaining more than 300-500 meters of elevation per day once you’re above 3,000 meters.

Include rest days in your trekking schedule, such as in Samagaun, to allow your body to adjust to the altitude.

2. Stay Hydrated

Drink plenty of water throughout the day to keep your body hydrated. Dehydration can make altitude sickness worse.

Avoid alcohol and caffeine, as they can dehydrate you and slow down your body’s ability to acclimatize.

3. Eat High-Energy Foods

Your body needs extra energy at high altitudes, so eat meals rich in carbohydrates and calories. For Manaslu Circuit Trek, foods like rice, pasta, potatoes, and soup are ideal.

Avoid heavy or greasy meals, which can be harder to digest at high altitudes.

4. Rest and Avoid Overexertion

Listen to your body and take breaks when needed. Overexerting yourself can increase your risk of altitude sickness.

Make sure you’re getting enough sleep each night to help your body recover and adjust.

5. Follow Proper Pacing

Walk at a steady, comfortable pace, especially on steep climbs. Pushing yourself too hard can lead to exhaustion and worsen symptoms of altitude sickness.

By following these practical tips, you’ll reduce your chances of experiencing altitude sickness and make the most of your Manaslu Circuit Trek.

Medications and Emergency Preparations

Altitude sickness is a serious concern on the Manaslu Circuit Trek, but proper medications and emergency preparations can help you stay safe. Understanding medication for altitude sickness on treks and being ready for emergencies are key to managing risks effectively.

1. Common Medications for Altitude Sickness

Diamox (Acetazolamide): This is the most commonly used medication to prevent and treat altitude sickness. It helps your body adjust to high altitudes by speeding up acclimatization.

Take Diamox as prescribed, usually starting 1-2 days before gaining high elevation and continuing until you descend.

Always consult a doctor before taking any medication to ensure it’s safe for you.

2. Emergency Steps for Severe Cases

If symptoms like confusion, severe breathlessness, or loss of coordination occur, it may indicate High Altitude Cerebral Edema (HACE) or High Altitude Pulmonary Edema (HAPE).

The first step is to descend immediately to a lower altitude. This is the most effective way to treat severe altitude sickness.

Carry a portable oxygen cylinder and know how to use it in emergencies.

3. Importance of Trekking with Experienced Guides

Trekking with guides trained in altitude sickness response is essential. They can recognize early symptoms, advise on medication, and coordinate emergency rescues if needed.

Guides can also help plan a safe itinerary with acclimatization days to reduce risks.

Having the right medication for altitude sickness on treks and being prepared for emergencies ensures a safer and more enjoyable Manaslu Circuit Trek.

Preparing for High-Altitude Trekking: Fitness and Mindset

Getting ready for high-altitude trekking means working on your fitness and mental strength. Knowing how to prepare for high-altitude trekking and following safe trekking practices for high altitudes will help you handle the challenges of the Manaslu Circuit, especially while crossing the Larkya La Pass.

1. Fitness Training for High Altitudes

• Do cardio exercises like hiking, running, cycling, or swimming 3-4 times a week to build your stamina and improve your breathing.
• Strengthen your legs and core with exercises like squats, lunges, and planks to handle steep climbs and descents.
• Stretching or yoga can make your muscles more flexible and lower your chances of getting injured.

2. Practice Trekking at Higher Altitudes

• Hike at moderate altitudes before starting the Manaslu Circuit to help your body adjust to the lower oxygen levels.
• Gradually increase the altitude during your practice hikes to mimic the trek’s conditions.

3. Mental Preparation for Challenges

• Trekking at high altitudes can be tough. Break the trek into smaller goals to make it feel more manageable.
• Use deep breathing or mindfulness techniques to stay calm when things get difficult.
• Picture yourself completing the trek to stay motivated and confident.

By training your body and preparing your mind, you’ll be ready for the challenges of the Manaslu Circuit. Following these safe trekking practices for high altitudes will make your trek safer and more enjoyable.
