Hi
@Wendal,
I think you are almost correct in your assessment below - and yet not quite correct. As I understand matters and I could be wrong:
Agreed.
But I'm uncomfortable about this bit. We can be
as if T1, but definitely not T1, or as if T2, yet not T2.
The cause of our D has nothing to do with the autoimmune condition that destroys some people's insulin production
and defines a T1 diagnosis. That autoimmune condition doesn't necessarily just stop there either and T1s can, often do, have other medical vulnerabilities because of their underlying autoimmune condition.
Once pancreatic damage has occurred AND diabetes is an outcome of that damage then that diabetes may need an insulin treatment path (hence as if T1). Or could be treated satisfactorily by oral meds. Those oral meds could work forever or pancreatic functionality may decline to the point that an insulin dosing regime becomes necessary. Treatment by oral meds and/or a subsequent insulin regime could = as if T2.
It might be helpful to see this in a wider perspective: pancreatic damage can occur from many different circumstances, not just from pancreatitis. There are people who have needed to take steroids for an entirely different medical condition and those steroids have over time caused damage to their pancreas resulting in their becoming diabetic. Diabetes from steroids is also neither T1 nor T2, but it's still diabetes and needs treatment. Similarly alcoholism can bring about pancreatic damage and diabetes. An International Symposium before the Covid epidemic met to address the diagnosis and treatment for those people with diabetes from pancreatic damage,
recognising that some diabetes was simply neither T1 nor T2. The Symposium came up with categorisations of T3 a-k (I think). T3c was selected specifically for damage from pancreatitis and physical damage whether from accident or surgery. But damage from steroids or alcohol and many other causes were given a different letter. At that time the WHO noted the Symposium's recommendations but didn't endorse them - so the initiative was stalled. But gradually T3c is gaining acceptance, particularly for damage from pancreatitis and I've noticed it seems to be becoming associated with other damage, such as from steroids.
The common features for T3 (a-k) are:
pancreatic damage resulting in diabetes;
diabetes that is not caused by an autoimmune condition (T1) or excessive natural insulin resistance (T2);
diabetes that sits alongside a different ailment - eg pancreatitis or in my case pancreatic cancer;
that other ailment might well be needing medication that sits in contradiction of treating the diabetes and that other treatment might well take precedence over diabetic treatment;
all of these T3(x) diabetes may need treatment by oral meds or insulin dosing.
I've seen the Symposium's report and I thought I'd kept a digital copy. But I simply can't find it - most frustrating.
Just to add to the confusion - in 2016 there was a proposal in the United States to use the designator of Type 3 diabetes (sometimes seen as T3D) to describe the interlinked association between type 1 and type 2 diabetes, and Alzheimer's disease. I don't think this T3 descriptor has any official status and it is not recognised by the American Diabetes Association (ADA).
@Duane62, I surrendered my panc'y in return for a cure for my pancreatic cancer. So I know virtually nothing about how pancreatitis damage is measured or assessed to support a diagnosis of T3c.
My instinct is that, as
@Wendal has already said, the diagnosis would be arrived at on a case by case basis AND in 2007/8/9 if you weren't a recognisable T1 anyone with diabetes was routinely diagnosed then as T2. T3c was not in anyone's vocabulary then.
I joined in this dialogue because it seemed to me from your earlier posts that you had enough background markers from your pancreatitis to make you T3c rather than T2. I still feel this is the case -
but I am not medically qualified. What remains clear to me is that your GP should be encouraged / persuaded / co-erced into helping you nail this down and at the very least prescribe test strips to help you manage your diabetes; that should be regardless of whether you finally get an amended diagnosis. Your pancreatic history should set you apart from more routine T2 (not that T2 is particularly routine or necessarily straightforward!). Testing alone could be a great help for you in managing your D. If you were T3c and if you were moved onto an insulin regime that should (emphasis on should rather than definitely will) lead to you having CGM on prescription as well as coming under a Hospital based Diabetes Team. As a T2, even with an insulin regime, getting CGM is not definite.
I do think your initiative in raising the question in this thread is a good idea and might help you further understand what you are wrestling with. Have you looked on pancreatitis specific websites?
