Environmental factor | Effect on blood glucose | Other effects and risks for wilderness athletes with diabetes |
---|---|---|
Extreme altitude (>4000 m) | Increases | Capillary blood glucose testing overestimation |
Moderate altitude (>1500 – <4000 m) | Unknown | |
Extreme heat | No direct effect | Increased heat illness, insulin becomes nonviable, increased insulin absorption |
Extreme cold | Variable | Possible poor insulin absorption, increased cold injuries, insulin freezing |
