Autoimmune or not: What is Type 1b diabetes?

On July 2, 2012 by Cherise Shockley

A few years ago, I read a couple of articles about Type 1b diabetes.  I haven’t met anyone living with this type of diabetes, until now.  A few weeks ago, Kiki wrote a blog post about her recent diagnosis of Type 1b diabetes; she was diagnosed with type 1 diabetes over 20 years ago.   I asked if I could share her story with you. She agreed.

Autoimmune or not: What's Type 1b diabetes?

I still have diabetes. But now, it’s called Idiopathic Type 1 diabetes, or Type 1b diabetes. I had never heard of this before the doctor called to give me my test results from last week. I had been wondering and wondering about it since last Friday and finally, during lunch, the doctor called to tell me that I have Type 1b diabetes.

Like everyone else in my life, you’re probably asking what that means for me and if I still have to take insulin. Yes, it’s practically the same thing and no, it doesn’t change the way I live my life. I just know now that I have the type of Type 1 that isn’t an autoimmune disease.

So what is it? It’s hereditary. Yep. It’s a gene that I carried around and something triggered the diabetes; an environmental factor. Interestingly enough, people with this type of diabetes are usually misdiagnosed to believe that they have Type 2 diabetes when in fact, it’s Type 1. There are even times of insulin independence, says the first article I read after Googling the terminology.

Nonetheless, what I gathered is that this type of diabetes doesn’t have anything attacking it. I don’t produce insulin but unlike the autoimmune Type 1a, which means that it was a person’s own body attacking itself, my pancreas just doesn’t want to work.

This form of type 1 diabetes is not autoimmune in nature, and tests for islet cell antibodies will come up negative. People with type 1 B have an insulin deficiency and can experience ketoacidosis (a high blood sugar emergency), but their need for insulin injections typically waxes and wanes over time.

Islet cells are those that make insulin and islet cell antibodies are those that attack them (in an autoimmune situation).

Now, why testing for this? Well, I had never been tested before. But the reason why these questions came up are very interesting. About a year ago, I decided to try the HCG diet. I can already hear people yelling at me regarding this, but nevertheless, I did it and it worked. The side affect of this diet was the fact that I cut my insulin usage by more than half while on it. It was incredible. By the end of the diet, I realized that I could go without insulin and did for about a day and a half. It was insane not to wear a pump or take injections, yet my blood sugar was maintained in the 100-120s. After looking up the side affects for HCG, I saw that one was

Because it takes about 24 hours for your system to clear itself of the hormone, the next day when I checked myself without eating, my sugar had skyrocketed.

That was a year ago. Recently, my mom saw a news story about a guy who had been misdiagnosed for 15 years and only had to now take a pill to regulate his blood sugar. From my mom’s insight, she said that they did not test for insulin production but only tested for sugar in the blood. What happened was that he was still able to produce insulin and it was Type 2 diabetes. She thought I might have the same issue. Obviously, it is not.

The doctor even thought I might have been misdiagnosed and said there was a possibility of having Type 2 diabetes. Pills only? I got excited thinking about the freedom that would involve. But alas, I’m still a Type 1 diabetic with more questions. I plan on continuing the search for answers.

One step at a time, right? Maybe one day I’ll accidentally stumble upon a cure.

  • Is type 1b different than type 1.5?

    • yes …in order to be classified as LADA you have to test positive for antibodies, in 1B everything is nearly exact as type 1a except the we do not test positive for antibodies, we do not go through a ‘honeymoon’ like some LADA, 1b and 1a are both sudden onset and we do not produce any of our own insulin…

      1b is ideopathic variety, basically can’t pinpoint why the loss of function and occurs in roughly 10% of type 1′s from what I’ve read…

  • This is me as well… I’ve done quite a bit of research on it… it took a long time and many doctors to narrow it down…very frustrating to not know exactly what type…
