I wonder how quickly diabetes type 2 can occur? I cant seem to find much information online except that it can take years to develop symptoms but nothing about the levels. The thing is ive been diagnosed 3 months ago, i remembered in 2015 i once was tested for blood Sugar too, so yesterday i called the assistent and asked what levels it was. It appears that in 2015 i had a NON(!) Fasting level of 5, no HBa1c known.. 2 years later it's 9 and HBA1C is 50. Is this possible for type 2? Im so worried i am actually type 1, or something else is wrong with me.. today i panicked thinking ive no diabetes but pancreatic cancer.
