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.

  • When Doctors Make House Calls, Modern-Style!

    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 Tuesday’s newsletter, we asked you foryour opinion of telehealth for primary care consultations*, and got the above-depicted, below-described, set of responses:

    • About 46% said “It is no substitute for an in-person meeting with a doctor; let’s keep the human touch”
    • About 29% said “It means less waiting and more accessibility, while avoiding transmission of diseases”
    • And 25 % said “I find that the pros and cons of telehealth vs in-person balance out, so: no preference”

    *We specified that by “primary care” we mean the initial consultation with a non-specialist doctor, before receiving treatment or being referred to a specialist. By “telehealth” we mean by videocall or phonecall.

    So, what does the science say?

    A quick note first

    Because telehealth was barely a thing (statistically speaking) before the first stages of the COVID pandemic, compared to how it is now, most of the science for this is young, and a lot of the science simply hasn’t been done yet, and/or has not been published yet, because the process can take years.

    Because of this, some studies we do have aren’t specifically about primary care, and are sometimes about specialists. We think this should not affect the results much, but it bears highlighting.

    Nevertheless, we’ll do what we can with the science we have!

    Telehealth is more accessible than in-person consultations: True or False?

    True, for most people. For example…

    ❝Data was found from a variety of emergency and non-emergency departments of primary, secondary, and specialised healthcare.

    Satisfaction was high among recipients of healthcare, scoring 9-10 on a scale of 0-10 or ranging from 73.3% to 100%.

    Convenience was rated high in every specialty examined. Satisfaction of clinicians was high throughout the specialities despite connection failure and concerns about confidentiality of information.❞

    Dr. Wiam Alashek et al.

    whereas…

    ❝Nonetheless, studies reported perception of increased barriers to accessing care and inequalities for vulnerable patients especially in older people❞

    Ibid.

    Source: Satisfaction with telemedicine use during COVID-19 pandemic in the UK: a systematic review

    Now, perception of those things does necessarily equate to an actual increased barrier, but it is reasonable that someone who thinks something is inaccessible will be less inclined to try to access it.

    The quality of care provided via telehealth is as good as in-person: True or False?

    True, ostensibly, with caveats. The caveats are:

    • We’re going offreported patient satisfactionnot objective patient health outcomes (we found little* science as yet for the relative incidence of misdiagnosis, for example—which kind of thing will take time to be revealed).
    • We’re also therefore speaking (as statistics do) for the significant majority of people. However, if we happen to be (statistically speaking) an insignificant minority, well, that just sucks for us personally.

    *we did find some, but it wasn’t very helpful yet. For example:

    An electronic trigger to detect telemedicine-related diagnostic errors

    this one does look at the incidence of diagnostic errors, but provides no control group (i.e. otherwise-comparable in-person consultations) for comparison.

    While most oft-considered demographic groups reported comparable patient satisfaction (per racegender, and socioeconomic status, for example), there was one outlier variable, which was age (as we quoted from that first study above).

    However!

    Looking under the hood of these stats, it seems that age is not the real culprit, so much as technological illiteracy, which is heavily correlated with age:

    ❝Lower eHealth literacy is associated with more negative attitudes towards I/C technology in healthcare. This trend is consistent across diverse demographics and regions. ❞

    Dr. Raghad Elgamal

    Source: Meta-analysis: eHealth literacy and attitudes towards internet/computer technology

    There are things that can be done at an in-person consultation that can’t be done by telehealth: True or False?

    True, of course. It is incredibly rare that we will cite “common sense”, (as sometimes “common sense” is actually “common mistakes” and is simply and verifiably wrong), but in this case, as one 10almonds subscriber put it:

    ❝The doctor uses his five senses to assess. This cannot be attained over the phone❞

    ~ 10almonds subscriber

    A quick note first: if your doctor is using their sense of taste to diagnose you, please get a different doctor, because they should definitely not be doing that!

    Not in this century, anyway… Once upon a time, diabetes was diagnosed by urine-tasting (and yes, that was a fairly reliable method).

    However, nowadays indeed a doctor will use sightsoundtouch, and sometimes even smell.

    In a videocall we’re down to two of those senses (sight and sound), and in a phonecall, down to one (sound) and even that is hampered. Your doctor cannot, for example, use a stethoscope over the phone.

    With this in mind, it really comes down to what you need from your doctor in that consultation.

    • If you’re 99% sure that what you need is to be prescribed an antidepressant, that probably doesn’t need a full physical.
    • If you’re 99% sure that what you need is a referral, chances are that’ll be fine by telehealth too.
    • If your doctor is 99% sure that what you need is a verbal check-up (e.g. “How’s it been going for you, with the medication that I prescribed for you a month ago?”, then again, a call is probably fine.

    If you have a worrying lump, or an unhappy bodily discharge, or an unexplained mysterious pain? These things, more likely an in-person check-up is in order.

    Take care!

  • Protein-Stuffed Bell Peppers

    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.

    Hot, tasty, meaty, and vegan! You can have it all. And with this recipe, you’ll want to err on the side of overcatering, because everyone will want some. As for healthiness, we’ve got lycopene, lutein and a stack of other carotenoids, a plethora of other polyphenols, and a veritable garden party of miscellaneous phytochemicals otherwise categorized. It’s full of protein, fiber, vitamins, and minerals, relatively low-fat but the fats present are healthy. It’s antidiabetic, anti-CVD, anticancer, antineurodegeneration, and basically does everything short of making you sing well too.

    You will need

    • 4 large bell peppers, tops sliced open and innards removed (keep the tops; we will put them back on later)
    • 1 cup quinoa, rinsed
    • 1 can black beans, drained and rinsed
    • 1 small zucchini (diced)
    • 1 small eggplant (diced)
    • 1 small red onion (finely chopped)
    • ½ bulb garlic, minced*
    • 1 tbsp tomato paste
    • 1 tbsp chia seeds
    • 2 tbsp extra virgin olive oil
    • 2 tsp dried basil
    • 2 tsp dried thyme
    • 2 tsp black pepper, coarse ground
    • 2 tsp ground cumin
    • 1 tsp smoked paprika
    • ½ tsp MSG or 1 tsp low-sodium salt

    *we always try to give general guidelines with regard to garlic, but the reality is it depends on the size and strength of your local garlic, which we cannot account for, as well as your personal taste. Same situation with hot peppers of various kinds. This writer (it’s me, hi) would generally use about 2x the garlic and pepper advised in our recipes. All we can say is: follow your heart!

    Method

    (we suggest you read everything at least once before doing anything)

    1) Combine the quinoa with the chia seeds, and cook as per normal cooking of quinoa (i.e. bring to a boil and then simmer for about 15 minutes until cooked and fluffy). Drain and rinse (carefully, without losing the chia seeds; use a sieve).

    2) Heat your grill to a high heat. Combine the zucchini, eggplant, onion, garlic, and olive oil in a big bowl and mix well, ensuring an even distribution of the oil. Now also add the herbs and spices (including the MSG or salt) and mix well again. Put them all to grill for about 5 minutes, turning as necessary.

    3) Heat your oven to a high heat. Take the grilled vegetables and combine them in a bowl with the quinoa-and-chia, and the black beans, as well as the tomato paste. Mix everything well. Spoon the mixture generously into the bell peppers, replacing the tops (it can be loosely), and bake for about 5–10 minutes, keeping an eye on them; you want them to be lightly charred, but not a burnt offering.

    4) Serve! This dish works well as a light lunch or as part of a larger spread.

    (before going in the oven with lids replaced to keep moisture in)

    Enjoy!

  • Kidney Beans vs White Beans – 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 kidney beans to white beans, we picked the white.

    Why?

    It was close, and each has its strengths! Bear in mind, these are very closely-related beans. But as we say, there are distinguishing factors…

    In terms of macros, kidney beans have very slightly more fiber and white beans have very slightly more protein. But both are close enough in both of those things to call this a tie in this category.

    When it comes to vitamins, there are two ways of looking at this:

    1. kidney beans have more of vitamins B1, B2, B3, B6, B9, C, and K, while white beans have more vitamin B5, E, and choline
    2. kidney beans have slightly more of some vitamins that don’t usually see a deficiency, while white beans have 31x more vitamin E

    Nevertheless, we’re sticking by our usual method of noting that this is a 7:3 win for kidney beans in this category; we just wanted to note that in practical health terms, an argument can be made for white beans on the vitamin front too.

    In the category of minerals, kidney beans have slightly more phosphorus, while white beans have more calcium, copper, iron, magnesium, manganese, potassium, selenium, and zinc. An easy win for white beans this time.

    (In case you’re wondering about the margin on phosphorus, it was 0.2x more, so we’re not seeing a situation like white beans’ 31x more vitamin E)

    In short: both are great and both have their strengths. Enjoy both, together if you like! But if we have to pick one, we’re going with white beans.

  • What’s the difference between autism and Asperger’s disorder?
  • Menopause can bring increased cholesterol levels and other heart risks. Here’s why and what to do about it

    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.

    Menopause is a natural biological process that marks the end of a woman’s reproductive years, typically between 45 and 55. As women approach or experience menopause, common “change of life” concerns include hot flushes, sweats and mood swings, brain fog and fatigue.

    But many women may not be aware of the long-term effects of menopause on the heart and blood vessels that make up the cardiovascular system. Heart disease accounts for 35% of deaths in women each year – more than all cancers combined.

    What should women – and their doctors – know about these risks?

    Hormones protect hearts – until they don’t

    As early as 1976, the Framingham Heart Study reported more than twice the rates of cardiovascular events in postmenopausal than pre-menopausal women of the same age. Early menopause (younger than age 40) also increases heart risk.

    Before menopause, women tend to be protected by their circulating hormones: oestrogen, to a lesser extent progesterone and low levels of testosterone.

    These sex hormones help to relax and dilate blood vessels, reduce inflammation and improve lipid (cholesterol) levels. From the mid-40s, a decline in these hormone levels can contribute to unfavourable changes in cholesterol levels, blood pressure and weight gain – all risk factors for heart disease.

    Speedkingz/Shutterstock

    4 ways hormone changes impact heart risk

    1. Dyslipidaemia– Menopause often involves atherogenic changes – an unhealthy imbalance of lipids in the blood, with higher levels of total cholesterol, triglycerides, and low-density lipoprotein (LDL-C), dubbed the “bad” cholesterol. There are also reduced levels of high-density lipoprotein (HDL-C) – the “good” cholesterol that helps remove LDL-C from blood. These changes are a major risk factor for heart attack or stroke.

    2. Hypertension – Declines in oestrogen and progesterone levels during menopause contribute to narrowing of the large blood vessels on the heart’s surface, arterial stiffness and raise blood pressure.

    3. Weight gain – Females are born with one to two million eggs, which develop in follicles. By the time they stop ovulating in midlife, fewer than 1,000 remain. This depletion progressively changes fat distribution and storage, from the hips to the waist and abdomen. Increased waist circumference (greater than 80–88 cm) has been reported to contribute to heart risk – though it is not the only factor to consider.

    4. Comorbidities – Changes in body composition, sex hormone decline, increased food consumption, weight gain and sedentary lifestyles impair the body’s ability to effectively use insulin. This increases the risk of developing metabolic syndromes such as type 2 diabetes.

    While risk factors apply to both genders, hypertension, smoking, obesity and type 2 diabetes confer a greater relative risk for heart disease in women.

    So, what can women do?

    Every woman has a different level of baseline cardiovascular and metabolic risk pre-menopause. This is based on their genetics and family history, diet, and lifestyle. But all women can reduce their post-menopause heart risk with:

    • regular moderate intensity exercise such as brisk walking, pushing a lawn mower, riding a bike or water aerobics for 30 minutes, four or five times every week
    • a healthy heart diet with smaller portion sizes (try using a smaller plate or bowl) and more low-calorie, nutrient-rich foods such as vegetables, fruit and whole grains
    • plant sterols (unrefined vegetable oil spreads, nuts, seeds and grains) each day. A review of 14 clinical trials found plant sterols, at doses of at least 2 grams a day, produced an average reduction in serum LDL-C (bad cholesterol) of about 9–14%. This could reduce the risk of heart disease by 25% in two years
    • less unhealthy (saturated or trans) fats and more low-fat protein sources (lean meat, poultry, fish – especially oily fish high in omega-3 fatty acids), legumes and low-fat dairy
    • less high-calorie, high-sodium foods such as processed or fast foods
    • a reduction or cessation of smoking (nicotine or cannabis) and alcohol
    • weight-gain management or prevention.

    What about hormone therapy medications?

    Hormone therapy remains the most effective means of managing hot flushes and night sweats and is beneficial for slowing the loss of bone mineral density.

    The decision to recommend oestrogen alone or a combination of oestrogen plus progesterone hormone therapy depends on whether a woman has had a hysterectomy or not. The choice also depends on whether the hormone therapy benefit outweighs the woman’s disease risks. Where symptoms are bothersome, hormone therapy has favourable or neutral effects on coronary heart disease risk and medication risks are low for healthy women younger than 60 or within ten years of menopause.

    Depending on the level of stroke or heart risk and the response to lifestyle strategies, some women may also require medication management to control high blood pressure or elevated cholesterol levels. Up until the early 2000s, women were underrepresented in most outcome trials with lipid-lowering medicines.

    The Cholesterol Treatment Trialists’ Collaboration analysed 27 clinical trials of statins (medications commonly prescribed to lower cholesterol) with a total of 174,000 participants, of whom 27% were women. Statins were about as effective in women and men who had similar risk of heart disease in preventing events such as stroke and heart attack.

    Every woman approaching menopause should ask their GP for a 20-minute Heart Health Check to help better understand their risk of a heart attack or stroke and get tailored strategies to reduce it.

  • Workout Advice For Busy People

    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.

    Hampton at Hybrid Calisthenics always has very sound advice in his uplifting videos, and this one’s no exception:

    Key tips for optimizing workouts without burning out

    “We all have the same 24 hours” is a folly when in fact, some of us have more responsibilities and/or other impediments to getting things done (e.g. disabilities).

    A quick word on disabilities first: sometimes people are quick to point out Paralympian athletes, and “if they can do it, so can you!” and forget that these people are in the top percentile of the top percentile of the top percentile of human performance. If you wouldn’t disparagingly say “if Simone Biles/Hussein Bolt/Michael Phelps can do it, so can you”, then don’t for Paralympians either 😉

    Now, as for Hampton’s advice, he recommends:

    Enjoy short, intense workouts:

    • You can get effective results in under 30 minutes (or even just a few minutes per day) with compound exercises (e.g., squats, pull-ups).
    • Focus on full-body movements also saves time!
    • Push closer to failure when possible to maximize efficiency. It’s the last rep where most of the strength gains are made! Same deal with cardiovascular fitness, too. Nevertheless, do take safety into account in both cases, of course.

    Time your rest periods:

    • Resting for 2–3 minutes between sets ensures optimal recovery.
    • Avoid getting distracted during rest by setting a timer to stay focused.
    • 10almonds tip: use this time to practice a mindfulness meditation. That will greatly reduce the chance of you becoming distracted.

    Remember holistic fitness:

    • Fitness isn’t just about exercise; diet, sleep, and stress management are equally important for your fitness as much as for the rest of your health.
    • Better sleep and reduced stress will help you exercise more consistently and avoid junk food.

    Address burnout:

    • If feeling too exhausted to apply these tips, focus on getting better rest and reducing stress first.
    • Taking a short break to reset can help in the long run.

  • 100 Hikes of a Lifetime – by Kate Siber

    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.

    This is published by National Geographic, so you can imagine the quality of the photos throughout.

    Inside, and after a general introduction and guide to gear and packing appropriately, it’s divided into continents, with a diverse array of “trips of a lifetime” for anyone who enjoys hiking.

    It’s not a narrative book, rather, it is a guide, a little in the style of “Lonely Planet”, with many “know before you go” tips, information about the best time to go, difficult level, alternative routes if you want to get most of the enjoyment while having an easier time of it (or, conversely, if you want to see some extra sights along the way), and what to expect at all points.

    Where the book really excels is in balancing inspiration with information. There are some books that make you imagine being in a place, but you’ll never actually go there. There are other books that are technical manuals but not very encouraging. This one does both; it provides the motivation and the “yes, you really can, here’s how” information that, between them, can actually get you packing and on your way.

    Bottom line: if you yearn for breathtaking views and time in the great outdoors, but aren’t sure where to start, this will give you an incredible menu to choose from, and give you the tools to go about doing it.
