The only people who should be using insulin are the type 1 diabetics, who are a small minority of diabetics in Western society. I have a family member who ended up with pretty aggressive type 2 diabetes. He was overweight, ate like crap, etc. standard situation which ruined his insulin sensitivity. The doctors had him on a ton of medication and insulin. He started looking into it, and found that there are doctors running clinics that reverse type 2 diabetes, despite the fact that normal medical treatment usually results in type 2 being a chronic disease that worsens over time until it's debilitating or fatal (not to mention very expensive). The doctors running these clinics have been pointing out that type 2 diabetics still produce insulin, but their cells are insensitive to it... therefore, pumping them full of more insulin to temporarily reduce the blood sugar levels just exposes the cells to higher and higher insulin levels, increasing insensitivity over time. This is why it always gets worse under normal treatment, despite being curable. The treatment wasn't through any expensive drugs. It was just an extremely low-carb diet, replacing most of those calories with fat (which doesn't require much insulin response to metabolize), regular fasting (which gives your body time to resensitize to insulin), and moderate exercise (which forces the muscles to uptake blood sugar). Weight loss is also recommended if you're overweight, since that can interfere with hormones like insulin. My family member didn't go to one of these clinics, just followed the advice. He is no longer on insulin (per his doctor; he didn't just stop on his own), and has gone from over double the normal blood sugar level to almost always testing in a non-diabetic range. If you have type 2, please look into this rather than just paying to waste away on pharmaceuticals without trying anything else.
