Wilderness Medicine for Diabetics: Managing Blood Sugar in Remote Adventures
Diabetes doesn’t have to limit wilderness adventures, but it does require careful planning, vigilant monitoring, and understanding how environmental factors affect blood sugar control. Whether you have Type 1 or Type 2 diabetes, successful wilderness experiences depend on preparation, education, and having backup plans for every scenario.
Understanding Diabetes in Wilderness Settings
How Wilderness Activities Affect Blood Sugar
Factors That Lower Blood Sugar:
- Increased physical activity and hiking
- Irregular meal timing or missed meals
- Altitude changes affecting appetite
- Stress from challenging situations
- Cold weather increasing caloric needs
- Prolonged activity exceeding normal exercise levels
Factors That Raise Blood Sugar:
- Excitement and adrenaline from adventure
- Dehydration and electrolyte imbalances
- Infection or illness in remote settings
- Disrupted sleep patterns
- Pain or injury stress response
- Certain high-altitude medications
Type 1 vs Type 2 Considerations
Type 1 Diabetes Challenges:

Target Blood Sugar Ranges:
- Before activity: 120-180 mg/dL (6.7-10.0 mmol/L)
- During activity: 100-250 mg/dL (5.6-13.9 mmol/L)
- Avoid exercise if >300 mg/dL (16.7 mmol/L) or ketones present
During Activity Monitoring
Frequent Testing Schedule:
- Test every 1-2 hours during moderate activity
- Test every 30-60 minutes during strenuous activity
- Test immediately if feeling symptoms
- Test before and after rest stops
- Test before consuming food or glucose
- Document all readings with activity level
Activity Modification Guidelines:
- Blood sugar <100 mg/dL: Consume 15g carbs, retest in 15 minutes
- Blood sugar 100-120 mg/dL: Consume 10g carbs before activity
- Blood sugar >250 mg/dL: Test for ketones, avoid activity if positive
- Symptoms of low blood sugar: Stop activity immediately, treat
Evening Management
End-of-Day Protocol:
- Test blood sugar before dinner
- Calculate insulin needs based on day’s activity

- Test blood sugar 2 hours after dinner
- Take evening medications as prescribed
- Test blood sugar at bedtime
- Plan overnight snack if needed
Environmental Challenges and Solutions
Altitude Effects on Diabetes
Blood Sugar Changes at Altitude:
