China Virus and Diabetes

I have diabetes but I'm not a bloatloard, actually im wiry/skinny, low bodyfat but decent amount of muscle. Like basketball players bodies. My pancreas doesnt process sugar efficiently so I have to take pills to help with it.

People say if you have diabetes you are vulnerable to the virus, but is it really just the FAT people that have to worry? I haven't gotten the vaccine and don't plan to, I haven't been sick since I was a kid. Never got flu shots.

When people say diabetes is a risk for the virus, is it the diabetes, or just the obesity that most diabetic people are?

If I'm diabetic but in excellent lean shape, should I be concerned?
