What is type 1.5 diabetes? It’s a bit like type 1 and a bit like type 2 – but it’s often misdiagnosed

While you’re likely familiar with type 1 and type 2 diabetes, you’ve probably heard less about type 1.5 diabetes.

Also known as latent autoimmune diabetes in adults (LADA), type 1.5 diabetes has features of both type 1 and type 2 diabetes.

More people became aware of this condition after Lance Bass, best known for his role in the iconic American pop band NSYNC, recently revealed he has it.

So, what is type 1.5 diabetes? And how is it diagnosed and treated?

There are several types of diabetes

Diabetes mellitus is a group of conditions that arise when the levels of glucose (sugar) in our blood are higher than normal. There are actually more than ten types of diabetes, but the most common are type 1 and type 2.

Type 1 diabetes is an autoimmune condition where the body’s immune system attacks and destroys the cells in the pancreas that make the hormone insulin. This leads to very little or no insulin production.

Insulin is important for moving glucose from the blood into our cells to be used for energy, which is why people with type 1 diabetes need insulin medication daily. Type 1 diabetes usually appears in children or young adults.

Type 2 diabetes is not an autoimmune condition. Rather, it happens when the body’s cells become resistant to insulin over time, and the pancreas is no longer able to make enough insulin to overcome this resistance. Unlike type 1 diabetes, people with type 2 diabetes still produce some insulin.

Type 2 is more common in adults but is increasingly seen in children and young people. Management can include behavioural changes such as nutrition and physical activity, as well as oral medications and insulin therapy.

How does type 1.5 diabetes differ from types 1 and 2?

Like type 1 diabetes, type 1.5 occurs when the immune system attacks the pancreas cells that make insulin. But people with type 1.5 often don’t need insulin immediately because their condition develops more slowly. Most people with type 1.5 diabetes will need to use insulin within five years of diagnosis, while those with type 1 typically require it from diagnosis.

Type 1.5 diabetes is usually diagnosed in people over 30, likely due to the slow progressing nature of the condition. This is older than the typical age for type 1 diabetes but younger than the usual diagnosis age for type 2.

Type 1.5 diabetes shares genetic and autoimmune risk factors with type 1 diabetes such as specific gene variants. However, evidence has also shown it may be influenced by lifestyle factors such as obesity and physical inactivity which are more commonly associated with type 2 diabetes.

What are the symptoms, and how is it treated?

The symptoms of type 1.5 diabetes are highly variable between people. Some have no symptoms at all. But generally, people may experience the following symptoms:

  • increased thirst
  • frequent urination
  • fatigue
  • blurred vision
  • unintentional weight loss.

Typically, type 1.5 diabetes is initially treated with oral medications to keep blood glucose levels in normal range. Depending on their glucose control and the medication they are using, people with type 1.5 diabetes may need to monitor their blood glucose levels regularly throughout the day.

When average blood glucose levels increase beyond normal range even with oral medications, treatment may progress to insulin. However, there are no universally accepted management or treatment strategies for type 1.5 diabetes.

Type 1.5 diabetes is often misdiagnosed

Lance Bass said he was initially diagnosed with type 2 diabetes, but later learned he actually has type 1.5 diabetes. This is not entirely uncommon. Estimates suggest type 1.5 diabetes is misdiagnosed as type 2 diabetes 5–10% of the time.

There are a few possible reasons for this.

First, accurately diagnosing type 1.5 diabetes, and distinguishing it from other types of diabetes, requires special antibody tests (a type of blood test) to detect autoimmune markers. Not all health-care professionals necessarily order these tests routinely, either due to cost concerns or because they may not consider them.

Second, type 1.5 diabetes is commonly found in adults, so doctors might wrongly assume a person has developed type 2 diabetes, which is more common in this age group (whereas type 1 diabetes usually affects children and young adults).

Third, people with type 1.5 diabetes often initially make enough insulin in the body to manage their blood glucose levels without needing to start insulin medication. This can make their condition appear like type 2 diabetes, where people also produce some insulin.

Finally, because type 1.5 diabetes has symptoms that are similar to type 2 diabetes, it may initially be treated as type 2.

We’re still learning about type 1.5

Compared with type 1 and type 2 diabetes, there has been much less research on how common type 1.5 diabetes is, especially in non-European populations. In 2023, it was estimated type 1.5 diabetes represented 8.9% of all diabetes cases, which is similar to type 1. However, we need more research to get accurate numbers.

Overall, there has been a limited awareness of type 1.5 diabetes and unclear diagnostic criteria which have slowed down our understanding of this condition.

A misdiagnosis can be stressful and confusing. For people with type 1.5 diabetes, being misdiagnosed with type 2 diabetes might mean they don’t get the insulin they need in a timely manner. This can lead to worsening health and a greater likelihood of complications down the road.

Getting the right diagnosis helps people receive the most appropriate treatment, save money, and reduce diabetes distress. If you’re experiencing symptoms you think may indicate diabetes, or feel unsure about a diagnosis you’ve already received, monitor your symptoms and chat with your doctor.

  • Pistachios vs Walnuts – Which is Healthier?

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Our Verdict

    When comparing pistachios to walnuts, we picked the pistachios.

    Why?

    Pistachios have more protein and fiber, while walnuts have more fat (though the fats are famously healthy, the same is true of the fats in pistachios).

    In the category of vitamins, pistachios have several times more* of vitamins A, B1, B6, C, and E, while walnuts boast only a little more of vitamin B9. They are approximately equal on other vitamins they both contain.

    *actually 25x more vitamin A, but the others are 2x, 3x, 4x more.

    When it comes to minerals, things are more even; pistachios have more iron, phosphorus, potassium, and selenium, while walnuts have more copper, magnesium, manganese, and zinc. So this category’s a tie.

    So given two clear wins for pistachios, and one tie, it’s evident that pistachios win the day.

    However! Do enjoy both of these nuts; we often mention that diversity is good in general, and in this case, it’s especially true because of the different mineral profiles, and also because in terms of the healthy fats that they offer, pistachios offer more monounsaturated fats and walnuts offer more polyunsaturated fats; both are healthy, just different.

    They’re about equal on saturated fat, in case you were wondering, as it makes up about 6% of the total fats in both cases.

  • Zuranolone: What to know about the pill for postpartum depression

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    In the year after giving birth, about one in eight people who give birth in the U.S. experience the debilitating symptoms of postpartum depression (PPD), including lack of energy and feeling sad, anxious, hopeless, and overwhelmed. 

    Postpartum depression is a serious, potentially life-threatening condition that can affect a person’s bond with their baby. Although it’s frequently confused with the so-called “baby blues,” it’s not the same. 

    The baby blues include similar, temporary symptoms that affect up to 80 percent of people who have recently given birth and usually go away within the first few weeks. PPD usually begins within the first month after giving birth and can last for months and interfere with a person’s daily life if left untreated. Thankfully, PPD is treatable and there is help available

    On August 4, the FDA approved zuranolone, branded as Zurzuvae, the first-ever oral medication to treat PPD. Until now, besides other common antidepressants, the only medication available to treat PPD specifically was the IV injection brexanolone, which is difficult to access and expensive and can only be administered in a hospital or health care setting. 

    Read on to find out more about zuranolone: what it is, how it works, how much it costs, and more. 

    What is zuranolone?

    Zurzuvae is the brand name for zuranolone, an oral medication to treat postpartum depression. Developed by Sage Therapeutics in partnership with Biogen, it’s now available in the U.S. Zurzuvae is typically prescribed as two 25 mg capsules a day for 14 days. In clinical trials, the medication showed to be fast-acting, improving PPD symptoms in just three days

    How does zuranolone work? 

    Zuranolone is a neuroactive steroid, a type of medication that helps the neurotransmitter GABA’s receptors, which affect how the body reacts to anxiety, stress, and fear, function better.

    “Zuranolone can be thought of as a synthetic version of [the neuroactive steroid] allopregnanolone,” says Dr. Katrina Furey, a reproductive psychiatrist, clinical instructor at Yale University, and co-host of the Analyze Scripts podcast. “Women with PPD have lower levels of allopregnenolone compared to women without PPD.”

    How is it different from other antidepressants?

    “What differentiates zuranolone from other previously available oral antidepressants is that it has a much more rapid response and a shorter course of treatment,” says Dr. Asima Ahmad, an OB-GYN, reproductive endocrinologist, and founder of Carrot Fertility

    “It can take effect as early as on day three of treatment, versus other oral antidepressants that can take up to six to 12 weeks to take full effect.” 

    What are Zurzuvae’s side effects? 

    According to the FDA, the most common side effects of Zurzuvae include dizziness, drowsiness, diarrhea, fatigue, the common cold, and urinary tract infection. Similar to other antidepressants, the medication may increase the risk of suicidal thoughts and actions in people 24 and younger. However, NPR noted that this type of labeling is required for all antidepressants, and researchers didn’t see any reports of suicidal thoughts in their trials.

    “Drug trials also noted that the side effects for zuranolone were not as severe,” says Ahmad. “[There was] no sudden loss of consciousness as seen with brexanolone or weight gain and sexual dysfunction, which can be seen with other oral antidepressants.”

    She adds: “Given the lower incidence of side effects and more rapid-acting onset, zuranolone could be a viable option for many,” including those looking for a treatment that offers faster symptom relief. 

    Can someone breastfeed while taking zuranolone?

    It’s complicated. In clinical trials, participants were asked to stop breastfeeding (which, according to Furey, is common in early clinical trials). 

    A small study of people who were nursing while taking zuranolone found that 0.3 percent of the medication dose was passed on to breast milk, which, Furey says, is a pretty low amount of exposure for the baby. Ahmad says that “though some data suggests that the risk of harm to the baby may be low, there is still overall limited data.”

    Overall, people should talk to their health care provider about the risks and benefits of breastfeeding while on the medication. 

    “A lot of factors will need to be weighed, such as overall health of the infant, age of the infant, etc., when making this decision,” Furey says. 

    How much does Zurzuvae cost? 

    Zurzuvae’s price before insurance coverage is $15,900 for the 14-day treatment. However, the Policy Center for Maternal Mental Health says insurance companies and Medicaid are expected to cover it because it’s the only drug of its kind. 

    Less than 1 percent of U.S. insurers have issued coverage guidelines so far, so it’s still unknown how much it will cost patients after insurance. Some insurers require patients to try another antidepressant first (like the more common SSRIs) before covering Zurzuvae. For uninsured and underinsured people, Sage Therapeutics said it will offer copay assistance

    The hefty price tag and potential issues with coverage may widen existing health disparities, says Ahmad. “We need to ensure that we are seeking out solutions to enable wide-scale access to all PPD treatments so that people have access to whatever treatment may work best for them.”

    If you or anyone you know is considering suicide or self-harm or is anxious, depressed, upset, or needs to talk, call the Suicide & Crisis Lifeline at 988 or text the Crisis Text Line at 741-741. For international resources, here is a good place to begin.

  • Stop Cancer 20 Years Ago

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Get Abreast And Keep Abreast

    This is Dr. Jenn Simmons. Her specialization is integrative oncology, as she—then a breast cancer surgeon—got breast cancer, decided the system wasn’t nearly as good from the patients’ side of things as from the doctors’ side, and took to educate herself, and now others, on how things can be better.

    What does she want us to know?

    Start now

    If you have breast cancer, the best time to start adjusting your lifestyle might be 20 years ago, but the second-best time is now. We realize our readers with breast cancer (or a history thereof) probably have indeed started already—all strength to you.

    What this means for those of us without breast cancer (or a history therof) is: start now

    Even if you don’t have a genetic risk factor, even if there’s no history of it in your family, there’s just no reason not to start now.

    Start what, you ask? Taking away its roots. And how?

    Inflammation as the root of cancer

    To oversimplify: cancer occurs because an accidentally immortal cell replicates and replicates and replicates and takes any nearby resources to keep on going. While science doesn’t know all the details of how this happens, it is a factor of genetic mutation (itself a normal process, without which evolution would be impossible), something which in turn is accelerated by damage to the DNA. The damage to the DNA? That occurs (often as not) as a result of cellular oxidation. Cellular oxidation is far from the only genotoxic thing out there, and a lot of non-food “this thing causes cancer” warnings are usually about other kinds of genotoxicity. But cellular oxidation is a big one, and it’s one that we can fight vigorously with our lifestyle.

    Because cellular oxidation and inflammation go hand-in-hand, reducing one tends to reduce the other. That’s why so often you’ll see in our Research Review Monday features, a line that goes something like:

    “and now for those things that usually come together: antioxidant, anti-inflammatory, anticancer, and anti-aging”

    So, fight inflammation now, and have a reduced risk of a lot of other woes later.

    See: How to Prevent (or Reduce) Inflammation

    Don’t settle for “normal”

    People are told, correctly but not always helpfully, such things as:

    • It’s normal to have less energy at your age
    • It’s normal to have a weaker immune system at your age
    • It’s normal to be at a higher risk of diabetes, heart disease, etc

    …and many more. And these things are true! But that doesn’t mean we have to settle for them.

    We can be all the way over on the healthy end of the distribution curve. We can do that!

    (so can everyone else, given sufficient opportunity and resources, because health is not a zero-sum game)

    If we’re going to get a cancer diagnosis, then our 60s are the decade where we’re most likely to get it. Earlier than that and the risk is extant but lower; later than that and technically the risk increases, but we probably got it already in our 60s.

    So, if we be younger than 60, then now’s a good time to prepare to hit the ground running when we get there. And if we missed that chance, then again, the second-best time is now:

    See: Focusing On Health In Our Sixties

    Fast to live

    Of course, anything can happen to anyone at any age (alas), but this is about the benefits of living a fasting lifestyle—that is to say, not just fasting for a 4-week health kick or something, but making it one’s “new normal” and just continuing it for life.

    This doesn’t mean “never eat”, of course, but it does mean “practice intermittent fasting, if you can”—something that Dr. Simmons strongly advocates.

    See: Intermittent Fasting: We Sort The Science From The Hype

    While this calls back to the previous “fight inflammation”, it deserves its own mention here as a very specific way of fighting it.

    It’s never too late

    All of the advices that go before a cancer diagnosis, continue to stand afterwards too. There is no point of “well, I already have cancer, so what’s the harm in…?”

    The harm in it after a diagnosis will be the same as the harm before. When it comes to lifestyle, preventing a cancer and preventing it from spreading are very much the same thing, which is also the same as shrinking it. Basically, if it’s anticancer, it’s anticancer, no matter whether it’s before, during, or after.

    Dr. Simmons has seen too many patients get a diagnosis, and place their lives squarely in the hands of doctors, when doctors can only do so much.

    Instead, Dr. Simmons recommends taking charge of your health as best you are able, today and onwards, no matter what. And that means two things:

    1. Knowing stuff
    2. Doing stuff

    So it becomes our responsibility (and our lifeline) to educate ourselves, and take action accordingly.

    Who nose what benefits you will gain today?

    This is James Nestor, a science journalist and author. He’s written for many publications, including Scientific American, and written a number of books, most notably Breath: The New Science Of A Lost Art.

    Today we’ll be looking at what he has to share about what has gone wrong with our breathing, what problems this causes, and how to fix it.

    What has gone wrong?

    When it comes to breathing, we humans are the pugs of the primate world. In a way, we have the opposite problem to the squashed-faced dogs, though. But, how and why?

    When our ancestors learned first tenderize food, and later to cook it, this had two big effects:

    1. We could now get much more nutrition for much less hunting/gathering
    2. We now did not need to chew our food nearly so much

    Getting much more nutrition for much less hunting/gathering is what allowed us to grow our brains so large—as a species, we have a singularly large brain-to-body size ratio.

    Not needing to chew our food nearly so much, meanwhile, had even more effects… And these effects have become only more pronounced in recent decades with the rise of processed food making our food softer and softer.

    It changed the shape of our jaw and cheekbones, just as the size of our brains taking up more space in our skull moved our breathing apparatus around. As a result, our nasal cavities are anatomically ridiculous, our sinuses are a crime against nature (not least of all because they drain backwards and get easily clogged), and our windpipes are very easily blocked and damaged due to the unique placement of our larynx; we’re the only species that has it there. It allowed us to develop speech, but at the cost of choking much more easily.

    What problems does this cause?

    Our (normal, to us) species-wide breathing problems have resulted in behavioral adaptations such as partial (or in some people’s cases, total or near-total) mouth-breathing. This in turn exacerbates the problems with our jaws and cheekbones, which in turn exacerbates the problems with our sinuses and nasal cavities in general.

    Results include such very human-centric conditions as sleep apnea, as well as a tendency towards asthma, allergies, and autoimmune diseases. Improper breathing also brings about a rather sluggish metabolism for how many calories we consume.

    How are we supposed to fix all that?!

    First, close your mouth if you haven’t already, and breathe through your nose.

    In and out.

    Both are important, and unless you are engaging in peak exercise, both should be through your nose. If you’re not used to this, it may feel odd at first, but practice, and build up your breathing ability.

    Six seconds in and six seconds out is a very good pace.

    If you’re sitting doing a breathing exercise, also good is four seconds in, four seconds hold, four seconds out, four seconds hold, repeat.

    But those frequent holds aren’t practical in general life, so: six seconds in, six seconds out.

    Through your nose only.

    This has benefits immediately, but there are other more long-term benefits from doing not just that, but also what has been called (by Nestor, amongst many others), “Mewing”, per the orthodontist, Dr. John Mew, who pioneered it.

    How (and why) to “mew”:

    Place your tongue against the roof of your mouth. It should be flat against the palate; you’re not touching it with the tip here; you’re creating a flat seal.

    Note: if you were mouth-breathing, you will now be unable to breathe. So, important to make sure you can breathe adequately through your nose first.

    This does two things:

    1. It obliges nose-breathing rather than mouth-breathing
    2. It creates a change in how the muscles of your face interact with the bones of your face

    In a battle between muscle and bone, muscle will always win.

    Aim to keep your tongue there as much as possible; make it your new best habit. If you’re not eating, talking, or otherwise using your tongue to do something, it should be flat against the roof of your mouth.

    You don’t have to exert pressure; this isn’t an exercise regime. Think of it more as a postural exercise, just, inside your mouth.

    Quick note: read the above line again, because it’s important. Doing it too hard could cause the opposite problems, and you don’t want that. You cannot rush this by doing it harder; it takes time and gentleness.

    Why would we want to do that?

    The result, over time, will tend to be much healthier breathing, better sinus health, freer airways, reduced or eliminated sleep apnea, and, as a bonus, what is generally considered a more attractive face in terms of bone structure. We’re talking more defined cheekbones, straighter teeth, and a better mouth position.

    At 10almonds we talk often of the health benefits of walking, so what’s new here?

    As the subtitle suggests: a new scientific exploration!

    Dr. Shane O’Mara is a professor of experimental brain research—and a keen walker. Combining his profession and his passion, he offers us a uniquely well-grounded perspective.

    While the writing style is very readable, there’s a lot of science referenced here, with many studies cited. We love that!

    We begin our journey by learning what we have in common with sea squirts, and what we have different from all other apes. What we can learn from other humans, from toddlers to supercentenarians.

    As one might expect from a professor of experimental brain research, we learn a lot more about what walking does for our brain, than for the rest of our body. We’ve previously talked about walking and cardiovascular health, and brown adipose tissue, and benefits to the immune system, but this book remains steadfastly focused on the brain.

    Which just goes to show, what a lot there is to say for the science-based benefits to our brain health, both neurologically and psychologically!

    One of the things at which Dr. O’Mara excels that this reviewer hasn’t seen someone do so well before, is neatly tie together the appropriate “why” and “how” to each “what” of the brain-benefits of walking. Not just that walking boosts mood or creativity or problem-solving, say, but why and how it does so.

    Often, understanding that can be the difference between being motivated to actually do it or not!

    Bottom line: if there’s a book that’ll get you lacing up your walking shoes, this’ll be the one.

  • The Polyvagal Theory – by Dr. Stephen Porges

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Do you ever find that your feelings (or occasionally: lack thereof) sometimes can seem mismatched with the observed facts of your situation? This book unravels that mystery—or rather, that stack of mysteries.

    Dr. Porges’ work on this topic is, by the way, the culmination of 40 years of research. While he’s not exactly a household name to the layperson, he’s very respected in his field, and this book is his magnum opus.

    Here he explains the disparate roles of the two branches of the vagus nerve (hence: polyvagal theory). At least, the two branches that we mammals have; non-mammalian vertebrates have only one. This makes a big difference, because of the cascade of inhibitions that this allows.

    The answer to the very general question “What stops you from…?” is usually found somewhere down this line of cascade of inhibitions.

    These range from “what stops you from quitting your job/relationship/etc” to “what stops you from freaking out” to “what stops you from relaxing” to “what stops you from reacting quickly” to “what stop you from giving up” to “what stops you from gnawing your arm off” and many many more.

    And because sometimes we wish we could do something that we can’t, or wish we wouldn’t do something that we do, understanding this process can be something of a cheat code to life.

    A quick note on style: the book is quite dense and can be quite technical, but should be comprehensible to any layperson who is content to take their time, because everything is explained as we go along.

    Bottom line: if you’d like to better understand the mysteries of how you feel vs how you actually are, and what that means for what you can or cannot wilfully do, this is a top-tier book
