Is Climbing Kilimanjaro Safe?

Acute Mountain Sickness, More Commonly Known As Altitude Sickness, Is The Single Biggest Killer On Kilimanjaro. This May Surprise A Few People Who, Given The Large Number Of Trekkers Who Climb Kilimanjaro Each Year, Are Under The Mistaken Impression That Africa’s Highest Mountain Is Also A Safe Mountain. Unfortunately, As Any Mountaineer Will Tell You, There’s No Such Thing As A Safe Mountain, Particularly One Nearly 6000m Tall With Extremes Of Climate Near The Summit And Ferociously Carnivorous Animals Roaming The Lower Slopes. Your Biggest Enemy On Kilimanjaro, However, Is Likely To Be Neither The Weather Nor The Wildlife But The Altitude. Unsurprisingly, KINAPA Are Shy About Revealing How Many Trekkers Perish On Kili Each Year But What Is Known Is That, During The Millennium Celebrations, When The Mountain Was Swamped By More Than A Thousand Trekkers On New Year’s Eve Alone, Three Died And Thirty-Three More Had To Be Rescued. The Authorities Are Doing What They Can To Minimize The Number Of Deaths: Guides Are Given Thorough Training In What To Do If One Of Their Group Is Showing Signs Of Altitude Sickness And Trekkers Are Required To Register Each Night Upon Arrival At The Campsite And Have To Pay A US$20 ‘Rescue Fee’ As Part Of Their Park Fees.
But You Too Can Do Your Bit, By Avoiding AMS In The First Place. The Pages In This Section Discuss In Detail What AMS Actually Is, How It Is Caused, The Symptoms And, Finally, How To Avoid It. Read This Section Carefully: It May Well Save Your Life.

Altitude Sickness On Kilimanjaro And Other Health Problems

Acute Mountain Sickness (AMS) The Percentage Of Oxygen In The Atmosphere At Sea Level Is About 21%. As Altitude Increases, The Percentage Remains The Same But The Number Of Oxygen Molecules Per Breath Is Reduced. At 12,000 Feet (3,600 M) There Are Roughly 40% Fewer Oxygen Molecules Per Breath So The Body Must Adjust To Having Less Oxygen. Altitude Sickness, Known As AMS, Is Caused By The Failure Of The Body To Adapt Quickly Enough To The Reduced Oxygen At Increased Altitudes. Altitude Sickness Can Occur In Some People As Low As 8,000 Feet, But Serious Symptoms Do Not Usually Occur Until Over 12,000 Feet. Mountain Medicine Recognizes Three Altitude Categories: High Altitude: 4,900 To 11,500 Ft (1,500 To 3,500 M) Very High Altitude: 11,500 To 18,000 Ft (3,500 To 5,500 M) Extreme Altitude: 18,000 Ft And Above (5,500 M And Above)
In The First Category, High Altitude, AMS And Decreased Performance Is Common. In The Second Category, Very High Altitude, AMS And Decreased Performance Are Expected. And In Extreme Altitude, Humans Can Function Only For Short Periods Of Time, With Acclimatization. Mount Kilimanjaro's Summit Stands At 19,340 Feet - In Extreme Altitude.

At Over 10,000 Feet (3,000 M), More Than 75% Of Climbers Will Experience At Least Some Form Of Mild AMS.

There Are Four Factors Related To AMS:

• High Altitude
• Fast Rate Of Ascent
• High Degree Of Exertion
• Dehydration

The Main Cause Of Altitude Sickness Is Going Too High (Altitude) Too Quickly (Rate Of Ascent). Given Enough Time, Your Body Will Adapt To The Decrease In Oxygen At A Specific Altitude. This Process Is Known As Acclimatization And Generally Takes One To Three Days At Any Given Altitude. Several Changes Take Place In The Body Which Enable It To Cope With Decreased Oxygen: The Depth Of Respiration Increases The Body Produces More Red Blood Cells To Carry Oxygen Pressure In Pulmonary Capillaries Is Increased, "Forcing" Blood Into Parts Of The Lung Which Are Not Normally Used When Breathing At Sea Level The Body Produces More Of A Particular Enzyme That Causes The Release Of Oxygen From Hemoglobin To The Body Tissues Again, AMS Is Very Common At High Altitude. It Is Difficult To Determine Who May Be Affected By Altitude Sickness Since There Are No Specific Factors Such As Age, Sex, Or Physical Condition That Correlate With Susceptibility. Many People Will Experience Mild AMS During The Acclimatization Process. The Symptoms Usually Start 12 To 24 Hours After Arrival At Altitude And Will Normally Disappear Within 48 Hours. The Symptoms Of Mild AMS Include:

• Headache
• Nausea & Dizziness
• Loss Of Appetite
• Fatigue
• Shortness Of Breath
• Disturbed Sleep
• General Feeling Of Malaise

Continuing On To Higher Altitude While Experiencing Moderate AMS Can Lead To Death.

Severe AMS Results In An Increase In The Severity Of The Aforementioned Symptoms Including: Shortness Of Breath At Rest Inability To Walk Decreasing Mental Status Fluid Build-Up In The Lungs Severe AMS Requires Immediate Descent Of Around 2,000 Feet (600 M) To A Lower Altitude. There Are Two Serious Conditions Associated With Severe Altitude Sickness; High Altitude Cerebral Edema (HACE) And High Altitude Pulmonary Edema (HAPE). Both Of These Happen Less Frequently, Especially To Those Who Are Properly Acclimatized. But, When They Do Occur, It Is Usually In People Going Too High Too Fast Or Going Very High And Staying There. In Both Cases The Lack Of Oxygen Results In Leakage Of Fluid Through The Capillary Walls Into Either The Lungs Or The Brain. High Altitude Pulmonary Edema (HAPE) HAPE Results From Fluid Build Up In The Lungs. This Fluid Prevents Effective Oxygen Exchange. As The Condition Becomes More Severe, The Level Of Oxygen In The Bloodstream Decreases, Which Leads To Cyanosis, Impaired Cerebral Function, And Death. Symptoms Of HAPE Include: Shortness Of Breath At Rest Tightness In The Chest Persistent Cough Bringing Up White, Watery, Or Frothy Fluid Marked Fatigue And Weakness A Feeling Of Impending Suffocation At Night Confusion, And Irrational Behavior Confusion, And Irrational Behavior Are Signs That Insufficient Oxygen Is Reaching The Brain. In Cases Of HAPE, Immediate Descent Of Around 2,000 Feet (600 M) Is A Necessary Life-Saving Measure. Anyone Suffering From HAPE Must Be Evacuated To A Medical Facility For Proper Follow-Up Treatment.

Bottled Oxygen

We Carry Bottled Oxygen On All Of Our Climbs As A Precaution And Additional Safety Measure. The Oxygen Cannister Is For Use Only In Emergency Situations. It Is NOT Used To Assist Clients Who Have Not Adequately Acclimatized On Their Own To Climb Higher. The Most Immediate Treatment For Moderate And Serious Altitude Sickness Is Descent. With Kilimanjaro's Routes, It Is Always Possible To Descend, And Descend Quickly. Therefore, Oxygen Is Used Strictly To Treat A Stricken Climber, When Necessary, In Conjunction With Descent, To Treat Those With Moderate And Severe Altitude Sickness. We Are Aware That Some Operators Market The Use Of Supplementary Personal Oxygen Systems As A Means To Eliminate The Symptoms Of AMS. To Administer Oxygen In This Manner And For This Purpose Is Dangerous Because It Is A Temporary Treatment Of Altitude Sickness. Upon The Cessation Of The Use Of Oxygen, The Client Will Be At An Even Higher Altitude Without Proper Acclimatization.
99% Of The Companies On Kilimanjaro Do NOT Offer Supplementary Oxygen - Because It Is Potentially Dangerous, Wholly Unnecessary And Against The Spirit Of Climbing Kilimanjaro. The Challenge Of The Mountain Lies Within The Fact That The Summit Is At A High Elevation, Where Climbers Must Adapt To Lower Oxygen Levels At Altitude. Using Supplementary Oxygen Is Akin To Putting The Mountain At Sea Level, Where Nearly Everyone Can Summit Large, One-Wheeled Rescue Stretchers Are Found On Mount Kilimanjaro But They Are Only Available Within A Small Area Of The Park. That Means That If A Climber Is Unable To Walk Due To Severe Altitude Sickness Or A Leg Injury That Compromises Mobility, Getting That Climber Down The Mountain Could Pose Difficult Challenges For Kilimanjaro Operators. Usually It Means Assisting The Injured Climber By Carrying Him Or Her On One's Back.
At The Peak Of Africa And Below, We Carry A Portable Stretcher At All Times In Case Of Emergencies When A Climber Is Unable To Walk On Their Own And The Trekking Party Is Some Distance Away From The Park's Stretchers. Our Portable Stretchers Are Compact, Strong And Lightweight. The Device Can Be Used To Evacuate An Injured Climber Quickly Off The Mountain. To Use, The Subject Is Secured To The Stretcher Using Straps. Then Porters Hold On To The Hand Grips To Usher The Climber To Safety.
