What is Altitude Sickness?
Altitude sickness (or acute mountain sickness) happens when your body cannot adjust to the lower oxygen levels and air pressure found at higher elevation. Symptoms range from a mild hangover-like feeling to life-threatening emergencies requiring immediate descent and medical emergency attention.
Most symptoms generally appear 6-12 hours after ascending. Although inconvenient and uncomfortable, many symptoms may resolve on their own or with intervention. While these symptoms are common, they should still be monitored for subtle signs of increasing severity.
Who is More Likely to Experience Altitude Sickness?
It is important to note that anyone can experience altitude sickness regardless of age, gender, or fitness level. You increase your risk to experience altitude sickness by ascending rapidly (such as flying or driving into high elevation within a few hours), drinking alcohol or take sedatives, and overexerting yourself too early. Even if you do not plan to participate in strenuous activities, you may still experience altitude sickness during your stay.
You May Be at a Higher Risk of Altitude Sickness Based on Disease and Pre-Existing Conditions:
People with existing heart and lung issues such as COPD, heart failure, sleep apnea, or sickle cell anemia may tolerate a low-oxygen environment poorly.
If you have experienced altitude sickness in the past, you are likely to experience similar symptoms in the future.
If you have a pre-existing condition, consider consulting with your physician before travel.

Common Symptoms of Altitude Sickness
Mild Altitude Sickness (Acute Mountain Sickness, AMS)
Headache is the most common and usually the first symptom people experience with altitude sickness.
Gastrointestinal symptoms can include nausea, vomiting, or loss of appetite.
Physical symptoms can include general fatigue, mild shortness of breath that is relieved by rest, decreased urination, or mild swelling of the hands and feet.
Mental status symptoms can include mild fatigue and mild insomnia.
If mild symptoms are ignored, or your body fails to adjust, you may find your symptoms worsen. This can lead to a severe and potentially life-threatening situation. Consider any combination of the below symptoms as critical warning signs to intervene.
Moderate Altitude Sickness (Moderate AMS)
Headache that is persistent and not relieved by over-the-counter pain medication.
Gastrointestinal symptoms including severe nausea and vomiting that prevent you from keeping liquids down.
Physical symptoms can manifest as extreme fatigue, even at rest; shortness of breath that is not relieved by rest, moderate swelling of the hands and feet, rapid heart rate, or a persistent dry cough.
Mental status changes potentially include anxiety, sudden changes in emotion, dizziness, or lightheadedness .

When moderate symptoms are ignored and no interventions are made, moderate AMS can quickly turn into a life-threatening medical emergency. Do not wait, consider any of the below signs and symptoms reason to seek emergency medical attention IMMEDIATELY. Delaying medical treatment can rapidly lead to coma or death.
Severe Altitude Sickness (MEDICAL EMERGENCY)
Worsening severe, pounding headache that is not relieved by over-the-counter pain medication.
Physical signs including (and not limited to) trouble or inability to walk, stumbling or loss of balance, chest pain, dry cough that may include producing frothy pink sputum, and blue or grey lips and nail beds.
Mental status changes can include confusion, irrational behavior, hallucinations, change in personality, decreasing responses to questions, or loss of consciousness.

The Best Way to Prevent Altitude Sickness in Estes Park:
While planning for your trip, there are steps you can take to mitigate your risk of experiencing altitude sickness.
Ascend Slowly:
If you have the opportunity, consider staying in Denver or a surrounding city to adjust to the change in altitude for 1-2 days before ascending to Estes Park. If you are traveling from a location that is close to sea-level, this can make a big difference in preventing altitude sickness from sudden ascent.
Increase Activity Levels Before Your Trip:
The more time you spend at your normal elevation doing cardiovascular exercise, the less risk you have of developing altitude sickness. Common activities include brisk walks, jogging or running, cycling, and swimming.
Before you start a workout regimen, it is always a good idea to consult your physician if making a major change.

Hydration:
Low humidity can cause your body to loose water at a rapid rate, especially with physical activity. Consume 8-12 cups of water (or 66-100 oz) of water per day. Ideally, you can start this hydration regiment a few days before your trip.
Diet:
Eat carb-heavy meals. Consider eating complex carbohydrates the first few days such as whole grains, leafy greens, and legumes. Your body digests these foods slowly and requires less oxygen to break down for energy compared to high-fat meals.
If you have a medical condition, you should always consult with a physician before making sudden or major changes to your diet.
Take It Easy:
Even if you're in good shape, consider taking the first few days of your trip to ease into physical activity. Overexerting yourself before your body has had the chance to adjust to a sudden altitude change drastically increases your risk of experiencing altitude sickness.

Supplements and Medications:
Herbal Supplements: Many visitors begin taking herbal supplements a few days before and during their stay at a higher elevation to support oxygen efficiency and help the body acclimate faster. One popular supplement is from the brand Altitude Adjustment. If you're visiting Estes Park, you can go to Rocky Mountain Pharmacy in town to purchase this brand.
Over-the-Counter NSAIDS such as ibuprofen can be effective in preventing mild headaches associated with rapid changes in altitude.
Always consult with a physician before starting new medications or beginning herbal supplements.

Treatment of Altitude Sickness
Even with planning and prevention techniques, there is no way to guarantee you will not experience altitude sickness during your stay. Below are some common interventions for mild to moderate altitude sickness.
Treatment of Mild Altitude Sickness (Acute Mountain Sickness, AMS)
For acute AMS, your goal should be rest to ease your discomfort and allow your body time to adjust to the altitude change.
Rest: Stop ascending. Do not travel to a higher elevation until your symptoms have resolved for 24 hours.
Hydrate: Drink plenty of fluids like water and electrolyte drinks, but avoid caffeine and alcohol.
NSAIDS: over-the-counter medications such as ibuprofen can be effective in preventing mild headaches associated with rapid changes in altitude.
Herbal supplements: Ginkgo biloba and Rhodiola rosea are popular options to help with altitude adjustment. An aforementioned common brand available at Rocky Mountain Pharmacy in Estes Park is Altitude Adjustment.
Always consult with a physician before starting new medications or beginning herbal supplements.
Treatment of Moderate-Severe Altitude Sickness (Moderate AMS)
When your symptoms fall into the moderate or severe immediate intervention is necessary to prevent symptoms from escalating to a life-threatening medical emergency.
Descend 1,000-3,000 feet immediately.
Absolute rest until symptoms have resolved.
If your symptoms worsen or fall under the "severe" category, do not delay in seeking immediate emergency medical assistance. If necessary, call 911 for assistance.
