Pancreatin and Diabetes

It is my understanding that insulin in the body comes from the pancreas. Is that a correct assumption? When insulin goes haywire in the body, is it because the pancreas is malfunctioning?

How does pancreatin interact with insulin? I have diabetes 2 and wonder if pancreatin will help with the digestion of sugar. Will taking pancreatin help to bring my sugar/blood numbers down? I currently take Metformin. How does pancreatin interact with Metformin?

Can taking pancreatin help with weight loss? Does it block the absorption of fat and/or carbohydrates?

Thank you for your attention to my questions. I look forward to hearing back from you. My e-mail address is ddstelly@comcast.net , and I truly appreciate your help.
