About This Guide
What this site is
Altitude Sickness Denver is a plain-language guide to feeling unwell at 5,280 feet — what causes it, what it feels like, how long it lasts, how to avoid it, and the small number of situations where it needs medical attention rather than patience.
It exists because the information available to a visitor at 11pm in a Denver hotel room tends to fall into two categories: national medical pages written for mountaineers going above 14,000 feet, and local businesses selling something. Neither answers the actual question, which is usually "is this normal, and what do I do tonight?"
Who publishes it
This site is published by Intravene, a mobile IV therapy provider serving the Denver metro and several other US markets. We're stating that at the top rather than the bottom, because it's the first thing you should know when reading health information.
Intravene operates under independent medical oversight from Guardian Medical Direction, a national physician-led medical direction group. Guardian provides medical oversight to medical spas, wellness centers, telemedicine companies and healthcare practitioners across the country, through a team of medical directors and physician collaborators.
Visits are carried out by registered nurses with critical-care and emergency backgrounds.

What we sell, and where we say so
Intravene provides mobile IV hydration in Denver. One page on this site — IV Therapy for Altitude Sickness — describes that service, what it costs, and the narrow circumstances where it's genuinely worth your money.
Every other page is guidance. Our prevention page explicitly names IV hydration among the things that do not prevent altitude sickness, because that's true. Our oxygen page states plainly that we don't offer oxygen and that oxygen targets the underlying problem more directly than we do.
We'd rather be the site that tells you to have an easy day and drink some water than the site that sells you something you didn't need. The first one is worth bookmarking.

How the guidance is sourced
Clinical content follows CDC high-altitude travel recommendations and standard wilderness and travel medicine guidance. Where evidence is mixed, or where a widely marketed remedy doesn't hold up to scrutiny, we say so rather than omitting it.
Pages carry the date they were last checked against current guidance. Our full method, including how we handle corrections: Editorial Policy
What this site is not
It is not a substitute for medical care, and it can't assess you. Altitude illness occasionally becomes serious quickly, and the red-flag lists throughout this site exist because that judgement call matters more than anything else we've written. If you're worried, call a doctor or 911 — not us.
