Hi. If you are noticeably overweight then you will have insulin resistance and that means your body has lots of insulin but the body can't use it due to fat deposits. The inability to use the insulin results in high blood sugar. Insulin is often offered if tablets fail but it may need quite large shots as the body will be inefficient in using it. With excess weight, however, it should help. There are some alternative injectables to insulin that are sometimes prescribed which will also help with weight loss e.g. Liraglutide; you may want to discuss these with the GP? Your best way forward apart from possible injections is to go for a low-carb diet as carbs, not fat, are the cause of much excess weight. Many of us on the forum have a reduced carb diet; even myself with a BMI of 22 as it avoids weight gain when on insulin. Your diagnosis of T2 is no doubt correct and moving to insulin or whatever won't make you a T1 as T1s have a failing pancreas producing little insulin. T2s may have excess insulin although eventually the pancreas may give up. The good news is that weight reduction can help the pancreas recover as well as reducing insulin resistance.
