We already knew that diabetes can create liver, pancreas, kidney, brain, skin, and extremeties damage. There was evidence that it was also linked to lung damage. It wasn’t clear however that the link was causation, not just correlation.
It was announced at the DUKPC conference today that a meta study over 17 large scale studies, on almost 500,000 participants, has shown that the link was indeed causation. The study, based on Mendelian randomsation, showed that an increase from 72mg/dl to 216mg/dl results in a 20% drop in lung function.
So that’s another reason to work hard at putting diabetes into remission (or not develop it in the first place).
