Hello
@Dump64 and Welcome to the forum.
Welcome also to the T3c club. You are part of a very small group of diabetics. To put that in perspective about 90% of all those with Diabetes Mellitus (DM) are T2 (their bodies make insulin but resist that insulin, leading to very elevated Blood Glucose (BG)) without medications or insulin, in conjunction with taut carb control. About 10% are T1 (they have an auto-immune condition and simply don't make any insulin), so take insulin by injection (or pump) and broadly can eat what they wish. T3 is for people whose pancreas has become damaged, from all sorts of circumstances and T3s are less than 1% of all those with DM; T3 comes in different flavours, from 'a to k', and T3c includes those people who get diabetes after pancreatitis, along with people like me who have little or no pancreas after surgery. I had pancreatic cancer and surrendered all of my panc'y. T3cs are rare!
This can cause difficulties, since most medical professionals have never even heard of T3c and can be very ignorant of the consequences and problems that this diagnosis can create. You are insulin dependent and should be treated as akin to T1. This is important. There are very few guidelines from the National Institute for Clinical Excellence (NICE) that even mention T3c. Most A&E clinics won't know that T3cs are insulin dependent. So if your medical notes refer to you as T1 gracefully accept that; if they say T3c, make sure that any medical professional knows that means you are insulin dependent - don't assume that they will already know this! Being akin to T1 means you should receive all the care that T1s should receive, which includes being under the care of a Hospital based Specialist Team and you should have direct access to a Diabetes Specialist Nurse (DSN). As you adjust to your new world of living with DM, you might well need support and guidance from your DSN - I certainly did.
I'm going to pause here, but leave you knowing that this forum is full of people with centuries of accumulated experience of managing DM. Feel free to ask questions - any questions (none are stupid). If you are happy to share a bit more with us, it would help to know:
How much of your pancreas has gone? I had a total pancreatectomy; others have partial removal and get some of the residual pancreatic functions. Your discharge paperwork from hospital should make this clear for you.
What insulins are you on? I was discharged on Multiple Daily Injections (MDI) with both a long lasting basal (then Levermir, now Tresiba) and short acting bolus (Novarapid) for all food.
Do you have Libre 2?
Are you carb counting or are you currently on fixed insulin doses before meals?
Sorry to bombard you with questions. You have a steep learning curve ahead of you, but it is manageable (we seem to survive!!) and there is lots of help and support from folks here, should you need it.
