Anyone Can Be Affected — Even Fit Travellers
Altitude sickness is caused by reduced oxygen levels at high altitude. Fitness, age, and previous experience do not protect you.
Introduction
Altitude sickness — formally known as Acute Mountain Sickness (AMS) — occurs when you ascend too quickly for your body to adapt to lower oxygen levels. It typically develops above 2,500m, though some people are affected at lower altitudes.
Symptoms
Symptoms usually begin within a few hours of reaching altitude: headache, nausea, fatigue, dizziness, and difficulty sleeping. In most cases, mild AMS resolves with rest and no further ascent.
Serious Progression
In some cases it can progress to more serious conditions — High Altitude Pulmonary Oedema (HAPE) or High Altitude Cerebral Oedema (HACE) — which are life-threatening without immediate descent.
Prevention & Medication
A preventive medication option can reduce the risk by stimulating faster breathing, which increases blood oxygen levels and speeds up acclimatisation. It is recommended by the British Mountaineering Council and travel health guidelines for travellers who cannot acclimatise gradually. Our pharmacist assesses whether it is suitable for you.

Medication Helps — But These Habits Matter Too
Any preventive treatment works best alongside sensible acclimatisation practice. Our pharmacist covers all of this at your appointment.
Ascend gradually
Above 3,000m, aim to gain no more than 300–500m of sleeping altitude per day. Build in a rest day every 3 days of ascent.
Hydrate consistently
Drink 3–4 litres of water per day at altitude. Dehydration amplifies headaches and fatigue — the earliest AMS symptoms.
Avoid alcohol for 48 hours after arrival
Alcohol impairs your body's acclimatisation response and worsens dehydration. Wait until your body has adjusted before drinking.
Descend at any sign of worsening
If symptoms don't improve with rest, or worsen at all, descend immediately. Even 300–500m can produce rapid relief. Never ascend with symptoms.
The primary approach is gradual acclimatisation — ascending no more than 300–500m of sleeping altitude per day above 3,000m. Where your itinerary does not allow this (for example, flying directly into a high-altitude city), a preventive medication option may be clinically appropriate. Our pharmacist assesses whether this is suitable for you at your consultation.
