Diabetes Type 1

Type 1 diabetes tends to start when people are under 25, although it can be diagnosed later in life. With Type 1 diabetes (also called insulin-dependent or juvenile diabetes) the body's immune system destroys, or attempts to destroy, the cells in the pancreas that produce insulin. Insulin is the hormone that allows glucose to enter the cells of the body to provide fuel. When glucose can't enter the cells, it builds up in the blood and the body's cells literally starve to death. Everyone with Type 1 diabetes must take daily insulin injections and regularly monitor their blood glucose levels. The cause of Type 1 diabetes is unknown but it is thought to be an autoimmune disease, where the body's immune system destroys the cells in the pancreas that produce insulin. Not all diabetes in children and teenagers is the kind called Type 1. Type 2 diabetes is being seen increasingly in young people. Where Type 1 diabetes always requires insulin, Type 2 can require insulin but often it can be treated with other medicines such as tablets. This section deals only with young people who have Type 1 diabetes. We have talked to a range of young people who've lived with Type 1 diabetes from those wh Continue reading >>

    Please forgive an interloper from the type 2 forum, copying a post I made there.
    I believe this is important for all types to know. In the fourteen years since I started reading diabetes forums and groups on the web I have seen too many new arrivals automatically mis-diagnosed as type 2 because of age or corpulence when further testing for type would have shown type 1 or MODY. Sometimes their honeymoon period lasted months or even years until insulin was finally added when pills and diet clearly became ineffective. And sometimes that period of poor control was costly in terms of complications.
    Half of All Type 1 Diabetes Develops After 30 Years of Age
    Miriam E Tucker September 20, 2016
    Onset of type 1 diabetes is just as likely to occur in people older than 30 years of age as in those younger, new research shows.
    The data were presented September 16, 2016, here at the European Association for the Study of Diabetes (EASD) 2016 Annual Meeting by Dr Nicholas JM Thomas, of the Institute of Biomedical and Clinical Science, University of Exeter Medical School, United Kingdom.
    Obtained using genetic data from the UK Biobank, the startling results refute the long-held belief that type 1 diabetes is primarily a "juvenile" condition.
    Clinically, the findings are particularly relevant for primary care, where people who develop autoimmune-mediated diabetes in adulthood are often misdiagnosed as having type 2 and prescribed metformin instead of insulin.
    "I think it's an eye-opener and obviously has implications for how we diagnose and manage people and also the education people receive. We very much focus on childhood and adolescence and perhaps people diagnosed later don't get the same education," Dr Thomas told Medscape Medical News in an interview.
    Still, identifying these individuals in primary care is challenging for a number of reasons: The vast majority of older adults with new-onset diabetes have type 2 diabetes, and antibody tests to identify autoimmune-mediated diabetes are too expensive for routine use. Moreover, overweight/obesity is nearly universal in type 2 but also common in type 1 diabetes. Read more on the link.

    This is so ery important. Iwas one of those over 30 years of age, Dx'd with T2. Gratned I didn't know anything at all about diabetes, so I didn't challenge the Dx. I figured Iwas an adult, and there it was. But...it appears that the HCP didn't read my chart nor look at me as a person. Medical history had absolutely no boxes checked - including no diabetes in my family back a few gnereations. I was very active physically - re very recently retired ballet dancer - so you know I had a physcially demanding job. And at 5'6" my weight had dropped from 112 lbs (my working weight) to about 100 lbs - without any weight loss eforts pon my part. I also had all the classic symptoms. I had to go for a few months to get the correct Dx, in the Emergency Dept of the hospital. I am lucky that it wasn't LADA with a longer onset, who knows what type of complicaiton development could have occurred.
    My point is that HCP's have to loook at the pateint, and be up to date on the onset of Dx info that is out there. I personally believe that one of the reasons for the change in nomenclature was the fact that age of onset doesn't determine type of D.. Yeah, the majority of PWD's have T2, but T1 does happen.
    Thanks Alan for psoting such hopeful info.

    Thanks, Alan, for being an interloper and posting this. It is actually really important that people in the Type 2 forums know about this problem of misdiagnosis (diagnosed as Type 2 when the person actually has Type 1), because of course the misdiagnosed person first shows up on the Type 2 forums. And note that this study only looked at people up to age 60, and of course new-onset Type 1 diabetes occurs after age 60, meaning that many more than half of all Type 1s are diagnosed in adulthood.
