A British research reveals the link between low levels of oxygen in the body and insulin resistance, a prime cause of diabetes. Insulin resistance is a big trigger for diabetes. It means that the body cells fail to respond to insulin that regulates blood sugar levels. Mount Everest climbers showed insulin resistance when they were put at high altitude areas with low oxygen levels  for 6 to 8 weeks.
This study opens up a huge scope for exploring the cause of diabetes type 2 and for improving the care for the critically ill patients.
