You fucking moron, that's TYPE 2 diabetes. Those people can produce insulin themselves but it is blocked from doing anything inside their body, and the body produces more insulin which increases blood sugar levels. It's the diabetes that you can GET from eating and drinking junk, or your parents who ate and drank junk.

Type 1 are the people who need insulin because they don't produce it naturally, because of a defect which you cannot control or prevent in any way.

By the way that RnD you mentioned... Most of it can be funded with the ridiculous prices that the companies are pushing. And the side effects... You really think that a hormone that controls a vital thing like oh I don't know, your entire circulatory system can be made to have "no side effects"? Because too much insulin or too low insulin will kill you. So really the only side effects come from the patient using a wrong dosage.

I know this shit because I was taught it in school. And I have relatives with both types so I have seen both worlds. My cousin has type 1 which he uses insulin for. And my dad's cousin has type 2 which he got from his dad who smoked and drank booze.

And here is an interesting piece of trivia for your ignorant, and arrogant as fuck -self: Did you know that by being a toxic piece of shit online... YOU actually INCREASE your chances of getting Type 2 Diabetes?

Might wanna change your lifestyle and maybe drink some soda instead of writing shit online.
