It’s quite easy to prove that type 2 diabetes is a reversible disease. Have a look at this chart of the number of required drugs for treating the disease, over 12 months on three different treatments in a 2012 study:
The bottom two graphs are common variants of obesity surgery, where a large (healthy) part of the stomach is removed. Many patients suddenly don’t need drugs anymore, their diabetes completely goes away!
The point is not to recommend surgery that removes healthy organs – I don’t recommend that. The point it that type 2 diabetes can be a fully reversible disease. Luckily it’s not even necessary to remove healthy organs to do so, it’s also possible by just changing your lifestyle.
Here’s a longer post on the subject by the great Dr. Jason Fung:
I just spent a few days with Dr. Fung and we have some really interesting plans. If you’re at all interested in this topic I think you’ll love what we have coming up soon.
