One is too many, far too many, im newly diagnosed but I’ve been experimenting for months and I’ve discovered that riding low is horrible for you in so many ways, let alone the short term, I feel like he could be damaging his body permanently, in fact he is, any endo will tell you that low or high numbers damages your body irreparably after long term lows or highs constantly, and consistently, personally I used to love staying at 200 for example. I have since been staying within range for months, I’ve noticed it’s a lot of training your brain. If you stay at a certain number that you stay at a lot then you don’t have the thought to change it. Mostly because you don’t see the apparent problem at hand. As a T1D patient I can confidently say that is a problem, and one that you and him should work on changing ASAP, especially considering these. Now, with that said I am not an endo, simply a patient. Though a lot of T1s will tell you that this is unavoidable, while they’re right, sometimes some can blow it out of proportion and be dangerous with this in mind, I have no idea why or why not, but I can say that a lot of people that have it under control, which can look different for each person, if he has a CGM, then his chart technically should look pretty, you know, in between the lines, maybe even occasionally just above or below, but staying the same other than raises and lowering for meals (that’s according to my endo team at Vanderbilt University Health Center) and highs or lows should not be a problem you face often, if handled properly. The way I look at it is, it’s like driving a car, you can swerve and have your car out of control, and if your going the wrong direction swerve to the other, repeat, or you could slowly turn (i.e. dealing with your numbers early, which includes staying at 100-120 where you can, range is technically 80-180 however so try to take that into consideration especially before exercising or doing insulin, lower numbers usually mean higher carb meals, highs are usually lower, this is not a rule however) especially lows are dangerous, extremely so. It seems like he might have to take his range into consideration and I suggest getting his time in range, you can see this on apps like Dexcom clarity or apps like it, 70% to start with, and work up to 80%, having constant lows according to any endo is a major issue, especially if it’s more than once a week, same with highs, if these are rare and on holidays, it’s fine, but otherwise it’s incredibly dangerous and probably feels horrible without him realizing it because he’s gotten used to that feeling, this is just the info my endo team has given me and taught me, I am no doctor, just taught by many
I wish you and your husband good health, and happy hunting
