Understanding Altitude Sickness

Altitude sickness, or Acute Mountain Sickness (AMS), occurs when you ascend too quickly and your body doesn't have time to adjust to lower oxygen levels.

Symptoms to Watch For

Mild Symptoms:

  • Headache
  • Nausea or loss of appetite
  • Fatigue and weakness
  • Dizziness
  • Difficulty sleeping

Severe Symptoms (Requires Immediate Descent):

  • Confusion or inability to walk straight
  • Severe breathlessness at rest
  • Fluid in lungs (crackling breath sounds)
  • Blue lips or extremities

Prevention Strategies

  1. Choose a longer route: 7-8 days gives better acclimatization than 5-6 days
  2. Climb slowly: "Pole pole" (slowly slowly in Swahili) is your mantra
  3. Stay hydrated: Drink 3-4 liters of water daily
  4. Avoid alcohol and sleeping pills: They suppress breathing
  5. Eat well: Even if you don't feel hungry, maintain calorie intake
  6. Consider Diamox: Consult your doctor about this altitude sickness medication

The Golden Rule

"Climb high, sleep low." Many routes include acclimatization days where you climb to higher altitude during the day but return to sleep lower.

What If You Get Symptoms?

  • Tell your guide immediately - never hide symptoms
  • Rest and hydrate
  • If symptoms persist or worsen, descend
  • Remember: There's no shame in descending. The mountain will still be there.

Our guides are trained in altitude sickness recognition and carry oxygen and medical supplies for emergencies.
