You are suffering from Pancreatic diabetes. The way to control blood glucose better is by increasing insulin dose under care of your endocrinologist or diabetologist. Due to poor blood glucose control, fat can get deposited in the liver, which may lead to rise in SGOT/SGPT. Tight blood glucose control may improve SGPT.
The anti-cholesterol drugs may increase SGPT but rise is usually mild and the drug need not be stopped, but follow-up repeat blood SGPT after a month or so; if rise is less than 2-3 times nothing is to be done, only follow up. The drug is quite safe.
The pancreas reserve can be found out both for digestive enzymes as well as for insulin. Since you are requiring digestive enzymes in form of tablets, this itself means you are deficient in that. To check insulin reserve, exogenous insulin has to be stopped then blood glucose / Insulin assessed. Do it under care of your doctor only, as on stopping insulin injection, blood sugar may go up very high. With the type of your insulin chances of antibodies formation are negligible. Don't worry on this account.
