Signs and symptoms of Altitude Sickness

Altitude sickness is a serious health concern when trekking to Everest Base Camp, and it is important to be aware of the signs and symptoms.

Common signs and symptoms of altitude sickness include headaches, fatigue, nausea and vomiting, dizziness or light-headedness, and shortness of breath or rapid breathing.

These symptoms usually start 8-24 hours after ascending to higher altitudes. Trekkers need to be aware of these symptoms so they can recognize them early and take the necessary precautions to prevent the condition from worsening.

It’s also important for trekkers to understand that not everyone will experience the same symptoms at the same rate. Some people may have milder forms of altitude sickness while others may experience severe symptoms such as confusion, chest tightness, coughing up blood, impaired coordination or balance, an inability to walk in a straight line, or even loss of consciousness.

In more extreme cases, fluid can accumulate in the lungs or brain which can be fatal if left untreated.

To help lessen the chances of getting altitude sickness when trekking to Everest Base Camp it’s best practice to plan rest days for proper acclimatization, drink plenty of fluids, avoid alcohol and smoking, stay away from strenuous activity, wear loose-fitting clothing, wear sunscreen, keep warm with appropriate clothing layers, bring medications for headache relief (acetazolamide), and monitor physical activity levels throughout your trek.

If you experience any signs or symptoms listed above while at high altitudes it’s important to seek medical attention immediately as this could indicate more serious conditions related to high altitude exposure such as high altitude pulmonary oedema (HAPE) or high altitude cerebral oedema (HACE).

Preventative Measures for Altitude Sickness

Altitude sickness is a serious condition that can occur when trekking to Everest Base Camp, and it is important to take the necessary preventative measures to ensure you are well prepared and enjoy your experience safely.

The most important preventative measure is to acclimatize slowly. This means climbing as slowly as possible, taking rest days every 1000 meters of altitude gain, and sleeping at a lower altitude than where you were during the day.

It's also important to stay hydrated by drinking at least 3 litres of water daily, avoid alcohol and caffeine, and monitor physical activity levels throughout your trek.

Medication such as acetazolamide (Diamox) can be used for prevention or treatment of mild symptoms. However, it’s always best practice to seek medical advice before trekking to ensure you are physically prepared. Additionally, many trekkers find that wearing protective breathing masks helps reduce the risk of altitude sickness.

Finally, before setting off on a trek it’s essential to do some research into the terrain and weather conditions to be fully prepared for any eventuality.

For example, if there is snow then waterproof clothing will be required to keep warm. Trekkers should also bring first-aid kits with them in case of an emergency.

By following these preventative measures, trekkers can be well prepared and enjoy their experience safely without having to worry about altitude sickness or other health risks associated with this type of activity.

Altitude Sickness Treatment

Altitude sickness treatment should always begin with immediate descent to lower altitudes. Descending even 1000 meters can help alleviate symptoms and prevent further complications.

Once the person has been stabilized, they should be encouraged to rest for at least one or two days before beginning their ascent again.

Acetazolamide (Diamox) is a medication that can be taken to treat mild to moderate cases of altitude sickness.

It works by increasing the rate of urine output, which helps reduce fluid retention in the brain and lungs, allowing a person to acclimatize more quickly. It is important to take acetazolamide with food and other medications as instructed by your doctor.

Oxygen therapy is used in more severe cases of altitude sickness where a person may not be able to descend on their own due to exhaustion or other health issues.

Oxygen can help restore oxygen levels in the blood and improve symptoms such as headaches, dizziness, and nausea.

In extreme cases where a person may experience oedema, hospitalization may be required for treatment with diuretics and oxygen therapy until symptoms subside.

In some cases, steroid treatments are also used for more serious forms of altitude sickness such as high-altitude cerebral edema (HACE) or high-altitude pulmonary edema (HAPE).

When trekking to Everest Base Camp, you must take all necessary precautions against altitude sickness by acclimatizing slowly and monitoring your physical activity levels throughout your trek.

With proper preventative measures in place along with early recognition of signs and symptoms combined with prompt medical attention if needed, you can ensure an enjoyable experience while trekking at higher altitudes like Everest Base Camp without worrying about altitude sickness.
