Altitude Sickness

"Altitude sickness is caused by ascending to high altitudes too quickly, preventing the body from adapting to the reduced atmospheric pressure and thinner air. Common symptoms include headaches, nausea, and dizziness, which can be diagnosed based on your recent travel history and clinical presentation. You can start a consultation on the Mail My Meds platform today to ensure you are prepared for your next trip to high-altitude destinations."

Altitude sickness is a physical condition that affects travellers, climbers, and athletes who move to elevations typically above 2,500 metres. It is the body's natural reaction to the "thin air" found at high altitudes where there is less oxygen available for your lungs to breathe in.

The primary cause of altitude sickness is ascending to a high elevation too rapidly, which does not give your respiratory system enough time to adjust to lower oxygen saturation. While some people feel the effects immediately, others may notice symptoms developing 6 to 24 hours after reaching a higher altitude.

Common Symptoms

Symptoms vary significantly from person to person but typically include:

• Persistent headaches that do not improve with rest.
• Nausea and vomiting or a general loss of appetite.
• Dizziness and feeling lightheaded.
• Fatigue and shortness of breath during physical exertion.
• Difficulty sleeping or frequent waking during the night.

Common Treatments and Seeking Advice

The most effective treatment is to stop ascending or to descend to a lower altitude immediately if symptoms become severe. Medical treatments like carbonic anhydrase inhibitors are often used to speed up the acclimatisation process. You should seek urgent medical advice if you experience a persistent cough, confusion, or a loss of coordination, as these can indicate more serious complications.
