About Altitude

Symptoms of Altitude Sickness

• Headache
• Nausea
• Fatigue
• Nausea and vomiting
• Shortness of breath
• Lack of Appetite
• Disturbed sleep
• General Feeling of         malaise

The consequences of moderate altitude sickness can be serious. High altitude and lower air pressure can cause fluid to leak from the capillaries that can build up both in the lungs and in the brain. There are other conditions that can also cause these symptoms, therefore, evaluation by a medical provider is essential for an accurate diagnosis and appropriate treatment.

Tips on how to stay healthy and happy at Altitude

• Eat a high carb, low protein, low fat diet.
• Smaller more frequent meals.
• Hydrate only enough to maintain clear urine
• Avoid alcohol after 6pm for the first 48 hours
• Use sunblock SPF 30 on any exposed skin 
• UV rated sunglasses or goggles are essential to protect your eyes
• Do not over exert yourself for the first 48 hours

Treatment is multi-faceted and normally includes at least 48 hours of SUPPLEMENTAL OXYGEN which is considered a medical treatment/drug by the FDA. A complete medical history and physical obtained by a licensed medical provider is essential to determine a safe and effective dosage.

Dr. Gray was responsive, caring, timely, and very professional and knowledgeable…

Danielle came right away, checked my oxygen level and it was at 62% (Dangerously low)… She was extremely helpful and did exactly what needed to be done to get me better…

Very fast response time. Professional and caring doctor who took the time to educate and explain what was happening to my son who is 15 years old and had acute mountain sickness.

Cannot say enough about how your service is a vacation saver as we were ready to head back to denver. Danielle was awesome…

Excellent service. Les is a great professional that takes the time to get to know his patients.

Danielle was amazing! So kind & helped me with my symptoms in a professional & caring way!  Thank you for helping me with the horrible experience of altitude sickness in the comfort of our condo so that I didn’t have to go to the ER & wait! I would highly recommend High Altitude MOBILE Physicians!

My little 6y/o girl came down with altitude sickness our first night in town. It was 4am, the roads were slick, and the nearest ER was 20 miles away. I called HAMP and they were at my hotel room in 30-45 minutes. The NP (Les) was great with my little girl. He treated her and we were off to the slopes that afternoon. She was back to her old self. We had a great conversation, and I will save their info for future use.

Truly a lifesaver on a Saturday evening! Dr. Gray was so nice and accommodating. Highly recommended!
