Type 2 diabetes isn't reversible. It can be very well managed without the need for medication (in some cases), but it is not reversible.
It also has side effects which people don't understand, such neuropathy in hands and feet (sometimes leading to amputation), eye problems, fatigue and brain fog. Many people with T2 diabetes also have metabolic syndrome and have to take a cocktail of medications, which can cause side effects.
I could happily punch on the nose people who think T2 is a mild form of diabetes and is reversible.
PS. I have no idea what symptoms Abbott has - just saying!
