Hiking to altitudes around 6000 metres


How is your SpO2 ? Mine at 1000 meters is only 92% at best and goes below 88% when in an airplane ?


I carry an oximeter when climbing. At 5500 my reading was 78%. A slow ascent always helps it to feel easier.


I wonder if low sats contribute to poor glucose control. Its hard to assess as there are so many other competing factors…such as tiredness, lots or exercise, new food types, altitude affects on the pump?


Are you sure this is safe ?
