I think these are very common in Sweden? Pretty much every type I diabetic I've met here have a sensor and insulin pump. Is this a different type of sensor?

CGMs and pumps are already common; what's new here is continuous ketone monitoring alongside glucose

Ketones are only going to be present if you are exceptionally bad (very high carb diet) or exceptionally good (very low carb diet) at managing your blood sugar. It's not going to be terribly useful for your average diabetic who has fairly good control over their blood sugars.

I've fairly good control over not running my car out of the road, yet I have airbags...

Blood glucose levels affect lots of health functions. Diabetes represents an extreme end of the spectrum where the body's ability to regulate these fluctuations fails, but just because your body can get your levels in control eventually doesn't mean you won't suffer from the negative effects of it needing to do so. Maintaining consistent glucose levels improves mental health, weight management, sleep quality, muscle…

sample of 1, but yeah changing my diet (very low sugar, more veggies) did alter my health visibly and rapidly. to the point that if I eat something too sweet too fast i have a very mild headache soon after, my system readjusted to not seek levels i grew up with

It may be worth getting checked out for fructose malabsorption. It means the main pathway for fructose absorption is not working and your gut only has less effective (and easily disrupted, looking at you Sorbitol) transport pathways with single digit grams capacity. Anything more and you will get symptoms. It is extremely hard to avoid fructose to get down to that level without careful attention so it is significantly under-diagnosed.

> very low sugar, more veggies Wearing a glucose monitor for a while showed me that some veggies are worse than the usual suspects: 80g of rice with fish gave me a glucose spike higher than a Nutella sandwich. Other veggies, like beans, surprisingly low.

Rice is not a veggie ffs, its not very healthy even in its best forms. Just a lot of simpler sugars. You are not doing anything healthy by eating it, and that glucose spike is very much expected just like from other junk food.

Rice is consumed a lot, and it has more things than "a lot of simple sugars". In fact, any "veggie" book would include many of recipes with rice, rice flour or rice noodles, as they are usually based in Asian cuisine. Also, as the current hell is gluten, some recipes suggest replacing wheat with rice.

It is common knowledge in the vegan world to pair lentils with rice, as they complement (rice is low lysine, high in methionine, lentils the other way). Lentils includes fiber that lowers the glycemic index of the overall meal, but also rice eases the otherwise heavy digestion of lentils. They both pair in other micronutrients (iron, zinc, selenium, magnesium, potassium).

A friend died of diabetic ketoacidosis. He loved technology and seeing people succeed. Thinking of him with this news. Miss you Dan. Grateful we're moving forward on so many fronts in the world.

Out of curiosity, Type I or Type II diabetes, if you (or others) are aware?

While this 1/2 typology is incomplete, diabetic ketoacidosis is a phenomenon generally relevant to type 1 family of conditions.

Normally (even with pure type 2!) glucose-ketone levels move in opposition: to put it simply ketone production is activated by low insulin, which is activated by low glucose. Ketone bodies are then consumed instead of glucose or excreted and generally homeostasis ensures that ketone levels do not approach anywhere close to ketoacidosis levels.

In cases where insulin production is broken (Type I diabetes, monogenic diabetes, mody) despite exogenous carbs raising blood glucose levels ketone body production is still active, however in most cases glucose is the preferred energy source, which leads to broken homeostasis of ketones, ketones accumulating and resulting diabetic ketoacidosis.

Type II family is characterized by high insulin. Some call it insufficient insulin, some call it insulin resistance, but the result is that insulin remains high and ketone production low. Regardless if the person is nominally healthy or has insulin resistance, the only way to trigger ketone production is to get insulin low for extended period, which is caused by lack of exogenous glucose. So either ketogenic diet or full-blown fasting.

Advanced and prolonged Type II diabetes (even if treated with insulin) can cause insulin production to drop along with insulin resistance, so the patient could develop Type I-like symptoms and risks, including DKA.

Rice is not a vegetable. It's not even the whole seed of a vegetable. It's just the starchy part. Try eating wholegrain rice.

Potatoes are vegetables? Rutabaga? Pumpking? Carrot? Turnip? They also punch high, and are consumed a lot by people that believes just "eating more veggies" would solve all their problems. And lets not talk about some fruits.

Wholegrain won't do magic here. Glycemic index of wholegrain flours and wholegrain products (bread, cookies...), even sugar free, can be higher than foods made with regular grain. E.g. glycemic index of butter cookies is 60-70 (https://glycemic-index.net/cookies-pastries/ https://glycemic-index-database.com/foods/butter-cookies-flo...), for a wholegrain baguette is 75 (https://glycemic-index.net/baguette-whole-grain/).

Since we're talking blood sugar and ketones, does anybody know if there is any line of such products that lets you export your data?

I'd love to start monitoring my glucose level, but i'd like to have the data in my own database so that maybe i can correlate that with other things.

This has nothing to do with continuous ketone measurements

As someone who has to deal with type 1 diabetes every day, this is marketing nonsense. No one needs ketones in the sensor - we need high-quality sensors, and Abbott's are only mediocre at best. They are not as bad as Dexcom, which is appalling, but they are still far from the superior quality of Medtronic/MiniMed which measure glucose exceptionally well. Ketones are rare. They can kill you, but before that happens, y…

I tend to agree that making the sugar measurements more robust is worth more than measuring the ketones at all. However, low sugar and high ketones can happen. And just getting notified when ketones pick up can be worth something too. The additional measurement is not useless seen from my perspective. As an example: I was on a study that gave T1D patients Dapagliflozin (Farxiga). During the study, while on a long hik…

Interesting. To me it seems there are bunch of special cases where ketone monitor can be big help.
