The Problem

It is time that the full scope of Type 1 diabetes is acknowledged, which includes millions of adults who are too frequently misdiagnosed as having Type 2 diabetes, an altogether different disease.

Reporting on ONE: The Ultimate Conference & Retreat for Adults with Type 1 Diabetes

The amazing folks at Taking Control of Your Diabetes (TCOYD) have completely outdone themselves.  Now, I was diagnosed with Type 1 diabetes as an adult, so I never attended famous-amongst-children Diabetes Camps.  Well, now I have attended a Type 1 retreat for adults (Diabetes Camp for adults), and I can say with certainty that it is fun, I am so much more knowledgeable, and I am inspired and motivated.  Diabetes Camp allows people to learn to care for themselves better, have fun, and realize they are not alone.  Diabetes camp for adults does all of those things, plus has cocktails and luaus!

The talks were incredible.  My favorite was “The Artificial Pancreas:  It’s Closer than You Think” with speaker/researcher legends Bruce Buckingham (Stanford endo), Ed Damiano (the brains behind the insulin/glucagon artificial pancreas iLet by BetaBionics), Jeffrey Brewer (Bigfoot Biomedical), Jacob Leach (Dexcom), and John Sheridan (Tandem).  The first automated insulin delivery device, the Medtronic 670G, is newly on the market, and I am hopeful that very soon we will have more options.

I was surprised by the talk that I attended by Tricia Santos, “Treatments for Type 1 Other than Insulin.”  Until now, I had simply dismissed drugs for Type 2 being used on Type 1s, but studies have shown that both the GLP-1 drugs and the SGLT2 Inhibitors greatly increase “time in range” for Type 1s.  Of course, there are potential side effects, but I will follow this more closely.

Stephen Ponder, of Sugar Surfing fame, gave an abbreviated talk on his methods of better control.  His book, of course entitled Sugar Surfing, is a must read.  Irl Hirsch, preeminent diabetes researcher and person with Type 1, talked about the limitations of the A1c test, and how good control is so much more than A1c.

Kerri Sparling, author of the blog SixUntilMe and author of the book Balancing Diabetes, gave several excellent talks addressing the emotional burden of diabetes.  And Kerri is hilarious, too!  My personal belief is that the emotional aspect, from the grief of diagnosis to the “staying motivated” after decades of life with Type 1, is the most challenging.

There was even a talk on “Alcohol and Diabetes:  Do They Mix?” by Jeremy Pettus.  Who knew that a speaker would put up a slide about “foofy drinks”?!  And BTW, a foofy drink is a pina colada, weighing in at ~60 grams of carbohydrates for one drink.  Jeremy reaffirmed my drink of choice, dry wines, which are low in carbs and have a negligible effect on blood glucose.

I connected up with some women from the Type 1 women’s group that I attend in Oakland/Berkeley.  I am so grateful for that group and having those connections.  I was blown away by the sheer numbers of people—over 500 people registered.  Now, some were Type 3s (spouses, other support people), but mostly this was a huge group of people with Type 1 diabetes.  Very inspiring.  The longest diagnosed person that I met was 66 years with Type 1, the shortest was less than 2 years.  Quite a span.

Other tidbits:
  • Adam Brown of DiaTribe has a new book out, Bright Spots and Landmines.  If you want the best, most practical tips on caring for yourself and your Type 1 diabetes, this highly readable book is it.  Also, I really recommend subscribing to the DiaTribe newsletter, which keeps up with the latest and greatest.
  • Chris Angell, diagnosed with Type 1 diabetes at age 30 (initially misdiagnosed as Type 2), created GlucoLift glucose tablets (, to provide an alternative to awful-tasting glucose tabs.  GlucoLifts were offered at the ONE “High” station, and I can tell you I will be ordering them!
  • Mark Atkinson of nPod is doing amazing investigations on the pancreases of Type 1 cadavers.  NPod is the Network for Pancreatic Organ Donors with Diabetes.  Mark is smashing myths and doing great research.

To any person that says, “There is too much money to be made on treating those of us with Type 1 diabetes, so there will be no cure,” I would challenge you to listen to these extraordinary men and women who are doing so much to improve our lives.  Many thanks to Steve Edelman, founder of TCOYD, and his team for putting on this extraordinary conference.

Out of this, I have made a list of goals for myself, and three of us plan to get together to look at our graphs, analyze information, and help improve our control (for me, time in range) and our lives.

From 2000, My First Published Article on Adult-Onset Type 1 Diabetes

In 2000, my first paper on adult-onset Type 1 diabetes was published in the newsletter of the International Diabetic Athlete Association (IDAA), a now-defunct organization.  I feared that I would receive hate mail for what I wrote, particularly for blasting ADA and JDRF, but instead I received so many email responses to the effect of, “thank you, finally someone has written the truth about Type 1 diabetes.”  When I read my words of 17 years ago, I realize we still have a long way to go, but in fact much progress has been made (for example, JDRF has a program and brochure for people with adult-onset Type 1 diabetes).  Here is my article from 2000, with a few 2017 updates as noted:


Type 1 or autoimmune diabetes has long been thought of as a disease of childhood; in fact, its previous designation was juvenile diabetes.  Only in recent years, with the advent of antibody testing, have some in the medical community recognized that Type 1 diabetes affects people of all ages, and in fact the majority of people who are newly diagnosed with Type 1 diabetes are adults.  In 1997, the Expert Committee on the Diagnosis and Classification of Diabetes Mellitus stated that, “immune mediated diabetes commonly occurs in childhood and adolescence, but it can occur at any age, even in the eighth and ninth decades of life” (The Expert Committee on the Diagnosis and Classification of Diabetes Mellitus, 1998).  However, the medical community has been slow to recognize this, and Type 1 diabetics diagnosed as adults are still treated as abnormalities and frequently given inappropriate treatment for the disease they have.  All too often, they are diagnosed with Type 2 diabetes, which is a fundamentally different disease not only clinically but genetically (Saudek, Rubin, and Shump, 1997), and the methods of treatment for the two diseases are also different.  The misdiagnosis typically results in under-treatment, and causes needless suffering.  Many International Diabetic Athletes Association (IDAA) members were diagnosed with Type 1 diabetes as adults, including Linda McClure, the IDAA Executive Director, who was diagnosed at age 36.  I was diagnosed with Type 1 diabetes at age 35, although I was briefly treated as if I had Type 2 diabetes and was sent to Type 2 diabetes education classes.  I discovered that the diabetes care community is not set up to deal with adults who are newly diagnosed with Type 1 diabetes, which is a situation that I believe needs to change.

It is well-known that the symptoms of Type 1 diabetes develop slightly more slowly in adults than in children.  I have a book that was published in 1958 that describes the progression of the symptoms of Type 1 diabetes in adults versus children (Dolger and Seeman, 1958).  In adults, the disease appears more gradually than childhood-onset Type 1, but its cause is the same (Karl and Riddle, 2000).  Unfortunately, because an adult with Type 1 diabetes typically has some functioning beta cells for some time after diagnosis, oral medications for Type 2 diabetes may to some degree control glucose levels right after diagnosis.  However, the correct treatment for Type 1 diabetes, at whatever age it is diagnosed, is exogenous insulin as early as possible, to control glucose levels, prevent further destruction of residual beta cells, and reduce the possibility of diabetic complications (Karl and Riddle, 2000).  A study of the Diabetes Control and Complications Trial (DCCT) demonstrated that initiating intensive insulin therapy (defined as three or more injections per day or continuous subcutaneous infusion of insulin, guided by four or more glucose tests per day) as soon as possible after Type 1 diabetes is diagnosed helps sustain endogenous insulin secretion, which in turn is associated with better metabolic control and lower risk for hypoglycemia and chronic complications (The Diabetes Control and Complications Trial Research Group, 1998).

The United States Centers for Disease Control and Prevention (CDC) states that the number of new cases of diabetes diagnosed per year is 798,000, and that Type 1 diabetes may account for 5% to 10% of all diagnosed cases of diabetes (from the CDC web site).  In fact, these percentages only include those who have been correctly diagnosed, and many recent studies indicate that that Type 1 diabetes is undercounted.  All too often, those with Type 1 such as myself who acquire the disease as adults are misdiagnosed as having Type 2.  Numerous studies, particularly recent ones that used antibody testing (islet cell antibody [ICA], anti-glutamic acid decarboxylase [anti-GAD] antibodies, etc.), indicate that approximately 10% of adults newly diagnosed with Type 2 diabetes in fact have the autoimmune markers for Type 1 diabetes and have been misdiagnosed (Wroblewski,, 1998).  In the landmark United Kingdom Prospective Diabetes Study (UKPDS) of Type 2 diabetes, 10% of the people that supposedly had Type 2 had ICA and/or anti-GAD antibodies, and clearly had Type 1 diabetes (Zimmet et. al., 1999).  The Endocrine Society estimates that as many as 20% of the people diagnosed with Type 2 diabetes actually have Type 1 diabetes (Endocrine Society web site).  The web site for the Lehigh University Diabetes Frequently Asked Questions (FAQs) states that, “Latent autoimmune diabetes in adults (LADA, or Type 1 diabetes in adults) may constitute as much as 50% of non-obese adult-onset diabetes.”

It is important that the type of diabetes a patient has is correctly assessed.  As stated previously, adults who acquire Type 1 diabetes should be put on exogenous insulin as early as possible, to control glucose levels, prevent further destruction of residual beta cells, and reduce the possibility of diabetic complications.  However, these are very clinical outcomes that fail to address the “human side” of misdiagnosis.  Those of us who have Type 1 diabetes but were initially diagnosed with Type 2 diabetes often suffered needlessly while on oral medications for Type 2 diabetes until we received appropriate treatment for the disease that we have (exogenous insulin).  The examples below describe the human impact of misdiagnosis.

June Biermann, prolific author of books on diabetes including The Diabetic’s Sports and Exercise Book, was diagnosed with Type 2 diabetes in 1967 at age 45, even though she failed to meet the criteria associated with Type 2 diabetes.  June was prescribed various oral medications for Type 2 diabetes, which did not adequately control her blood sugars, and after one year of much suffering and further weight loss (and several doctors), June was treated with exogenous insulin.  The standard for that time was one injection per day of NPH insulin.  Although for many years June referred to herself as a Type 1-1/2 diabetic, today she probably would be called a late-onset Type 1 diabetic.  Thirty years after her initial diagnosis as a Type 2 diabetic, June was given a C-peptide test, which indicated that her body did not produce any insulin.  June says, “The medical profession wanted to believe that I did not exist and that the problem was with me, when in fact it was the medical profession that ignored Type 1 diabetes in adults” and that she “has always felt misunderstood and ignored, and that [she] was a freak to the medical profession.”    June now does five or more injections per day of Humalog and NPH purified pork insulin, tests her blood sugar 7 to 8 times per day, and is looking forward to the introduction of glargine, the long-acting insulin analog without a peak.

Matt Hammer, an athlete who enjoys running and yoga, was diagnosed with diabetes in April 1997 at the age of 29.  Because of extreme fatigue and constant urination, Matt went to the Kaiser Permanente Acute Care Clinic near his home in Oakland, California.  His blood sugar was in the 400s (mg/dl).  The attending physician told Matt, “You have diabetes, avoid sugar, and someone will be calling you soon.”  He was given no other information and was sent home.  Matt was treated as if he had Type 2 diabetes, even though he had none of the risk factors, and he was both put on various oral medications and instructed to control his blood sugar with just diet and exercise.  For 21 months, Matt’s doctors tried to get his blood sugar under control with oral medications, diet, and exercise, but Matt’s condition continued to deteriorate.  In February 1999, while in Hawaii on a yoga retreat, I met Matt.  At lunch one day, he saw me injecting my insulin, and commented that he too had diabetes, but that he was on oral medications.  Because I saw that he was young, thin, and fit, and having experienced being incorrectly diagnosed myself, I asked Matt the next day if he had ever considered that he might have Type 1 diabetes and that he probably needed to be on insulin injections.  Matt said, “A light bulb went off in my head”, and as soon as Matt returned from Hawaii he went to Kaiser and insisted that he be put on exogenous insulin.  Matt now uses Humalog insulin in an insulin pump.  When Matt was finally correctly diagnosed he was, “angry that he received such bad care”, yet he had “a sense of relief that he could now get proper care after things had been out of control for so long.”  Matt feels that his misdiagnosis resulted in a lot of needless pain.  Today, he says that the hardest thing about diabetes is the need for constant daily discipline, but that although it is a really tough chronic disease, it is possible to live a good life if you can be disciplined.  Matt has an uncle who was diagnosed with diabetes as an adult 30 years ago, and his uncle has had both of his lower legs amputated as a result of his diabetes.  Matt’s uncle is on insulin injections, but Matt does not know what type of diabetes his uncle has.

Why is there a tendency to misdiagnose adults who have Type 1 as Type 2 diabetics?  I believe that there are several factors, the primary one being the emphasis by the diabetes medical community that Type 1 diabetes is a childhood disease.  I also think that doctors want to keep people off of insulin injections as long as possible, not realizing that for Type 1 diabetics there are significant short- and long-term benefits to beginning exogenous insulin as soon as possible.  The two principal organizations that address diabetes in the United States are the American Diabetes Association (ADA) and the Juvenile Diabetes Research Foundation (JDRF).  A common theme in materials published by both organizations is using diabetic children to garner more sympathy, and therefore more funding; thus, adults with Type 1 tend to be ignored because they do not garner as much sympathy.  The ADA’s emphasis is on Type 2 diabetes, and ADA recently published a position paper on Type 2 diabetes in children, even though Type 2 diabetes affects a significantly smaller number of children than the number of adults who acquire Type 1 diabetes.  Although I have asked ADA repeatedly why they have not written a corresponding position paper on adults who acquire Type 1, ADA has not responded to my question.  JDRF was founded by parents of children with diabetes.  JDRF appears to use children, again for sympathy, but also to distance themselves from Type 2 diabetes, which is perceived to be a lifestyle-related, preventable disease that typically occurs in older adults (2017 note:  Type 2 diabetes is a complex disease with many myths of its own).  JDRF’s publications and press releases emphasize that “our priority is juvenile, Type 1, diabetes, which primarily strikes children" (Ross Cooley, Chairman of the JDRF Board of Directors, November 2000).  Even JDRF's own figures say that, of the 30,000 new cases of Type 1 diagnosed each year, “over 13,000 of whom are children” (from the JDRF web site); thus JDRF’s own figures indicate that the majority of people diagnosed with Type 1 each year are adults.  However, those figures exclude the many adults who have late-onset Type 1 and are misdiagnosed as Type 2. 

Clearly it would be helpful if both ADA and JDRF acknowledged the full incidence of Type 1 diabetes in people of all ages.

If you are newly diagnosed, and unsure if you have Type 1 or Type 2 diabetes, you can be tested for anti-GAD antibodies (2017 note:  autoantibodies include GAD, ICA, IA-2, IAA, and ZnT8).  If an anti-GAD antibody test is performed when diabetes is first diagnosed, a positive result means you have Type 1 diabetes.  Also, the C-peptide test, which is a measurement of the body’s natural production of insulin, can be a way to gauge whether you have Type 1 or Type 2 diabetes (Connors, 2000).

All people deserve appropriate medical care for the disease that they have.  It is imperative that the true incidence of Type 1 diabetes in adults be known, and that the diabetes medical community recognizes us, so that we who acquire the disease as adults can live the best lives possible.
