How do I describe my diabetes, and use of humulin?

Hi @JudithD and welcome to the forums.

Unfortunately many of the regular posters are asleep now so you may have to wait a few hours before getting some more responses.

I'm sorry you've had such a stressful introduction to the world of insulin, and do feel that you could do with some more information from your diabetic team. (I guess this is the DN at your surgery? ) Have you had a chance to talk to your GP, even though you haven't seen an endocrinologist yet?

But I can make some comments. Firstly, illness can make blood sugars rise dramatically, so even excluding the pancreatitis situation it is possible that you would have needed insulin for your T2. Secondly, pancreatitis can cause diabetes T3c, which is basically a reduction in insulin production due to damage to the pancreas. Some T3cers need insulin, some don't, but they often get lumped in with T1s if they do need insulin. There is a T3c subforum here which may be of interest to you.

But remember, without a chat to your doctor and/or a look at your release notes from the hospital, you don't even know if you have T3c, so you really need to find out from them. And if they don't know, it might be time to ask for a referral to an endocrinologist.

As regards the insulin situation, it's not uncommon for T1s to have two doses of 24 hours so called basal insulin a day, mainly because those insulins often don't last quite 24 hours, and better coverage is attained by splitting the dose into two, and having two doses, usually morning and night. (T1s have fast acting insulin as well, so called bolus insulin, which is given before meals so as to mop up the carbohydrate in their food. )

Fasting bloods tend to be about 4, but this morning 3.4, so I don’t need the second dose 12 hours after the first. Anybody any advice?

Have you been educated about hypos? 3.4 is getting dangerously low and I'd expect you to treat it with glucose. Hopefully you had some symptoms (shakiness, hunger, sweating etc) when you got that low, as it makes life much easier if you aware of hypos. Once you are on insulin you should keep glucose (or equivalent) to hand at all times so that you can take some if you go too low. I would contact the nurse urgently and tell her about this low reading, and get more advice on insulin amounts and your other medication.

I'm going to stop here as I don't want to present you with a wall of text. In your position, I'd push my team hard for some additional information and help.

Good luck.
