Type 1 diabetes doesn't stop at the treeline. That's why the Dexcom G7 is as essential to me as crampons and rope.
On a ridge, at minus 15 degrees, wearing thick gloves, checking your blood sugar the classic way is simply impossible – but a glance at your wrist always works.
🎥 Aiguilles Marbrées – the moment the sensor warned me
Anyone climbing with type 1 diabetes knows the problem: on an exposed ridge, on ice, or in a storm, a classic finger-prick test is barely possible – and that's exactly when an unnoticed low or high can become dangerous. The Dexcom G7 measures automatically every five minutes and warns me before a value becomes critical – not after.
The value is always visible right on my smartwatch** – no phone needed, even with gloves on. Combined with an insulin pump in a closed-loop system, insulin delivery adjusts automatically, whether I'm asleep or climbing.
Handy for us: the G7 sensor is rated up to 5,000 meters of altitude* – comfortably covering all 82 four-thousanders in the Alps, including Mont Blanc, the highest of them all.
Real-time glucose readings right on your smartwatch** – no phone needed, no pricking, no stopping. One glance is enough.
Combined with an insulin pump, the loop system automatically adjusts insulin delivery – even while I sleep or climb.
Cold, wet, high altitude – the Dexcom G7 delivers precise readings in the harshest conditions. Exactly when it matters most.

As a father-son team, Tim and I want to climb all 82 four-thousanders in the Alps. Dexcom gives us reliable, continuous glucose readings – no matter how high, cold, or remote the climb.
