Can you go from T2 to T1 or....

back the other way?

Just wondering.

No. They are entirely separate conditions.

They remain separate and distinct regardless of treatment.

A type 2 diabetic may be treated with insulin. They will remain a type 2 diabetic, treated with insulin or not.

Type 1 diabetes is an autoimmune disease. It is incurable and lifelong. Once you have it, you keep having it. Until you die.
 
Type 1 Diabetes is an autoimmune condition, once diagnosed there is no known cure. Occasionally someonemay be misdiagnosed with Type 2 Diabetes and is then rediagnosed as Type 1 or LADA.
 
You can be misdiagnosed as T2 but T1 or even T1 but T2. However you could be T2 and your immune system later attacks your beta cells and become T1 or a T1 who becomes excessively insulin resistant like a T2 but you are still T1

What I am saying is they are separate and distinct but people are sometimes misdiagnosed
 
Logically, I guess you could go from T2 to T1, as T2 is a question of becoming insulin resistant while T1 is a question of all your insulin producing cells being killed by a faulty auto immune response. A T1 probably wouldn't notice becoming a T2, other than needing more insulin. It's also not unknown for T1s to be initially misdiagnosed as T2s, so in that sense it can happen. Not sure about T2s being misdiagnosed as T1s. but I suppose it's possible??? If you're correctly diagnosed as T1 then you're stuck with it, though advances in medical science keep happening so it's possible they'll be a cure one day.

May I ask a question related to this? Just once I read mention of 'Double Diabetes' whereby someone with poorly controlled T1 went on to develope T2. As there was little info given I was wondering if this is a myth or not and if not then how unlucky would a soul have to be to have both types.
 
Ooops! My question was answered even before I had finished typing it! This site is awsome.

It is not clinically possible to have "double diabetes" as a key factor in type 2 diabetes is excess insulin production and a type 1 diabetic cannot produce any insulin. A type 1 diabetic can however be insulin resistant. And this is colloquially (although not medically) referred to as double diabetes.

Thank you.
 
It's all dependent on the definitions. You can define T1 as no insulin production, or as reduced insulin production due to autoimmune reaction. Similarly, T2 means insulin resistant, but causes vary.

I'm t1, lada, since my first tests came back positive for antibodies. Later tests show no antibodies, and no insulin production, so I guess that's my beta cells all dead. I'm also T2 with severe insulin resistance, though obviously not increased insulin production. I noticed when the t2 kicked in alright - over a year I went from a daily dose of 20u up to about 100u, exercise started really hurting with lactic acid build up in my muscles and it became impossible to lose weight.

The number of organizations that want you to tick 1 OR 2 in their diabetes check box is huge. Some say you can't be both - e.g. my insurance company. Even after a letter from my consultant confirming I have both, they have told me I'm t1 because I take insulin. The NHS eye screening service have defined me as t2, because that's the type more likely to have diabetic eye changes. I gave up arguing. As long as I have informed them in writing that I have both, they can categorize me anyway they want.
 
Occasionally [@Grateful's italics] someonemay be misdiagnosed with Type 2 Diabetes and is then rediagnosed as Type 1 or LADA.

That is what I thought, too. Then just now I saw this in the Wikipedia article on LADA: "It is estimated that more than 50% of persons diagnosed as having non-obesity-related type 2 diabetes may actually have LADA" (https://en.wikipedia.org/wiki/Latent_autoimmune_diabetes_of_adults).

Surely that's a very high figure? The "50%" statement is not footnoted ... admittedly it only applies to T2s who were not overweight at diagnosis.

It scares me, for sure! I wonder where it came from.

I have read members' experiences of this and they report that some doctors refuse to acknowledge that LADA even exists. So, who knows about the numbers? It seems to be more common than at first glance, for sure.

I won't start worrying about it until or if my LCHF diet seems to have little effect on my bg.

The 50% figure doesn't surprise me. I gather 15 to 20% of 'T2's are not overweight and it's quite possible that 50% are mis-diagnosed T1s; I'm one of those and one of quite a few on this forum. My GP refused to accept I was actually T1 due to my age (60) even though stick thin. She had only just come off a diabetes training course which makes me question how up to date or comprehensive that training is. When I told her my 22yr old nephew ended-up in hospital with DKA not knowing he had diabetes she was surprised that had happened to someone 'so old'!
