Good afternoon
@jayspan. Sorry to read about the difficulties and frustrations you have had. Because I arrived at a T3c diagnosis, following my total pancreatectomy to resolve my Pancreatic Cancer (PC), I am not able to offer any real insight on T3c as a consequence of pancreatitis.
I do know that those of us diagnosed as T3c is a very small proportion of all folks with diabetes diagnosed at present. Probably well under 1%. There is repeated evidence from forum members that T3c is poorly understood by many Health Care Providers (HCPs) and I encountered this myself. My former GP, who was well aware that I'd had my pancreas totally removed, decided (unilaterally) that I was using too many test strips and removed them from my repeat prescriptions. I appealed, my GP sought guidance from my Hospital based DSN, who confirmed to my GP (without discussing this with me, that I didn't need to test more than at most 4 x daily. The professional competence of these 2 brought home to me how thin the awareness of 2 people central to my care didn't have the sense to realise how important such a matter was to anyone with no pancreas. At that time CGM was not an option.
Alas knowing this doesn't make matters right - but helps me to keep in sight that T3c is poorly understood and that I have to fight my corner (most of the time).
Within we T3c tiny minority of diabetic folk, there is considerable variation in treatment paths - very much dependent on how the damage to our panc'y was caused. Some end up being treated as if T2, oral meds only. Some have a basal insulin along with other meds for both their D and other ailments. Of those on a basal insulin the amount of total daily dose can vary from a small amount to even greater daily dose than your 32 units of Tresiba; I presume their bodies not only have damage to their panc'y and thus impaired home grown insulin production, but also high natural resistance to how their bodies can manage the insulin they are making. I can understand why HCPs unthinkingly equate you, taking 32 units of Tresiba, to being more akin to T2. It's wrong of course, your panc'y is damaged and that simply confirms you should be seen, first and foremost, as T3c.
To my mind there are 2 common factors amongst those of us diagnosed as T3c: we have damage to our panc'ys (hence the impaired insulin production) and almost universally we are also nursing and usually treating an ailment that caused the panc'y damage. For you pancreatitis, for me the PC. Frequently that panc'y damaging ailment needs more nursing than the diabetes and even if secondary it still routinely adds to the stress of managing our D.
I am on Tresiba as my basal and that has turned out to be brilliant for me, providing a stability that I wasn't expecting after my first year with Levermir. Because it has such a long lasting profile, c. 40 hrs, today's dose is topping up yesterday's dose. This does mean that changes to Tresiba dosing can take 3 or more days to provide a consequence. I do find I need to increase my Tresiba in the autumn and decrease it in the spring. Otherwise dose changes are infrequent for me. Along with my Tresiba I am MDI and NovoRapid is my bolus insulin. I am as if T1, but certainly not T1. I don't have the autoimmune conditions. I also seem to have relatively low insulin resistance; my Tresiba doses range from 9u in winter down to 7.5u in summer.
I was on novarapid but it would drop my blood sugar down to fast and make me faint, I was taking it after eating because I can't always finish the food and would adjust the units depending how much I ate, they stopped me on it and increased the slow release insulin, it has helped but still get spikes low and high.
I think the vast majority of us get a fair amount of BG variation in any 24 hr period and certainly in any week. Do you have CGM, or are you just using finger pricks? Could you provide a little more detail about how high and how low are these spikes and how frequently? Perhaps from that sort of detail we might be able to offer thoughts on potential improvements for your D management.
