Diabetes Guide to Staying Healthy at High Altitude

Oct 28, 2025

Ever wonder why your blood sugars go wild when you're hitting the slopes or flying high?

You're not alone! Living with diabetes, especially Type 1 (T1D) or Type 2 (T2D), means keeping an eye on a lot of things and altitude is definitely one of them. In this ultimate guide, we'll explore how elevation can impact your blood sugar and give you proven tips to stay in control, no matter how high you go!

The Altitude Rollercoaster

Imagine this: you're at the top of a mountain, breathing in the crisp air. For your body, this change in altitude is a bit like a surprise party; it sees it as stress. And what happens when your body is stressed? It releases a hormone called cortisol. High cortisol levels can make you more insulin resistant, meaning your body struggles to use insulin effectively, leading to higher blood sugar levels. You might notice your blood sugar creeping up, making you feel frustrated when you're trying to enjoy your adventure.

But here's the wild part: altitude is a double-edged sword! If you're actively moving at a high elevation, like hiking a trail or skiing down a mountain, your body's energy demands go way up. This increased activity can actually cause your blood sugar to drop quickly, sometimes even too low. So, whether you're relaxing or on the go, altitude can play tricks on your blood sugar.

Your Game Plan for High-Flying Blood Sugar Management

Don't let altitude wreck your amazing blood sugar control! Here's how a diabetes dietitian can help you develop a personalized game plan:

Medication Adjustments are Key: Your T1D dietitian or T2D dietitian can work with your care team to anticipate how altitude might affect your insulin doses (basal and bolus) or oral medications. You might need to adjust your doses before, during, or after your trip. Don't just accept high blood sugars; work with your team to prevent them!
Hydration is Your Best Friend: When your blood sugar is already elevated, being dehydrated makes it even harder to bring it down. Focus on staying well-hydrated with plenty of water and consider incorporating electrolyte-rich fluids. This is a simple yet powerful blood sugar management tip that pays off big, especially at higher elevations.
Smart T1D Meal Planning & Carb Counting: Knowing how to properly carb count for diabetes is always important, but even more so when your body is under stress from altitude. A Type 1 dietitian can help you fine-tune your meal plan and carb-counting strategies to account for these changes.
Easy Diabetes-Friendly Meals On the Go: Traveling often means eating out, which can be a challenge. Learn how to grocery shop on a budget and whip up easy diabetes-friendly meals even when you're away from home. Your diabetes educator can provide practical tips for healthy eating while traveling.
Monitor, Monitor, Monitor: Frequent blood sugar monitoring (or continuous glucose monitoring if you use it) is crucial when you're at a higher elevation. Be prepared for unexpected swings and have a plan for how to handle both high and low blood sugars.

Here's an example of what an amazing view at altitude looks like. Imagine experiencing this without the worry of blood sugar swings!

Ask the Diabetes Dietitian

Q: How quickly can altitude affect my blood sugar?
The effects can start within hours of ascending to a higher elevation. Everyone is different, but it's wise to start monitoring more closely as soon as you arrive.

Q: Should I bring extra supplies when traveling to an altitude?
Absolutely! Always pack extra insulin, syringes/pump supplies, test strips, and low blood sugar treatments. It's better to be over-prepared.

Q: Can a diabetes dietitian really help with this?
Yes! A Type 1 diabetes dietitian or Type 2 diabetes dietitian specializes in helping you manage all aspects of your diabetes, including unique situations like altitude changes. They can help you create a personalized plan.

Q: What if my care team doesn't talk about altitude?
It's important to have a care team that addresses all factors impacting your blood sugar. If altitude isn't a topic of discussion, consider bringing it up or exploring options for a new care team that includes a proactive diabetes educator.
