Jenny, I put up our terminology episode as a two parter because it was like an hour and it was like an hour and 15 minutes long. So I just kind of cut it in half. I thought it would make it easier for people to be able to find terms within them. But this morning, I was hoping to do the 1515 rule. Ah, so let me find people's feedback on 1515.
Jennifer Smith, CDE 4:17
I am I'm first very curious what people have to say about
Scott Benner 4:21
that. It's it's it's repetitive and and is it Yeah, so you know, just a number of 15 carbs 15 minutes rule one just says no. 15 carbs for a low is probably overkill. Not everyone treats I've learned with 15 carbs, we still only use two or four carbs to do a kind of watch and weight thing. So then a longer piece of feedback is the whole premise of the 1515 rule just does not do well for most people. If we had followed that consistently our toddler would have been consistently over 400 and we would have been having rebound Hi is because of these uncovered carbs. For example, 30 grams can move my child all the way up to 300 blood sugar. Now, I guess we should go over very quickly. 1515 Roll means if you find yourself low, your doctor will probably tell you have 15 carbs, and wait 15 minutes, correct retest. Now, do you think that that's a pre CGM? Theory?
Jennifer Smith, CDE 5:34
It's a, yes, that's where I was going to entirely. It's old. It's old. Like, I think the term brittle diabetes is old and not a purposeful explanation at all. But the 1515 really came from lack of any technology outside of a glucometer, that you could actually do a finger stick to confirm symptoms and see where things were going within another 15 minutes, right, because it is going to take some time for a finger stick value to show a difference in that era of, you know, that kind of use of limited technology. But we have so much information now with the technology we have, that that rule is explained very well by these comments. Absolutely. It's, I know how much it takes to bring my blood sugar up this much when I'm hovering here, or if it's a really quick like jump over a cliff drop in blood sugar, I might need this much more. I think we also understand insulin a little bit better, at least, you know, a lot of the podcast listeners understand insulin a little bit better, and the action of it. And you can say, well, I'm in the clear of any insulin on board. This low is being driven by Basal insulin only. And maybe because I got a little bit more active or busy or whatever, in this timeframe, I probably could get away with three or four grams of carb, and even this out and be totally fine. Versus again, 15 grams that you don't need,
Scott Benner 7:11
it feels it feels like to me even meters not that long ago. I mean, I want to sound like an old person. But not that long ago, even meters weren't all that accurate. And some still, actually but you know, I think now what does the FDA push them towards? Is it is it. You know, the percentage, like if your blood sugar is actually 100, the meter has to report back at least like 85 or 115 are in that range somewhere.
Jennifer Smith, CDE 7:35
There's a percent it's actually the the average difference that's allowable for the FDA to approve the meters each of the meters. I mean, if you're really interested, and you really want the information, don't throw away the little pamphlet that comes with your test strips, because it has that direct information for you. How much off could it be?
Scott Benner 7:57
Well, and but in the past, I mean, I remember people advocating for meters to get better and better to where they are now. And I can remember in the past where people are like my meter can be off by 20 25%. It's on correct. So with all this unknowable data happening, what is your blood sugar really? Is it falling? Or is it you know, is it rising, you would have no idea without a CGM. So this very, it's a safety feature from back in the day where the doctor is like, if you're low, eat 15 carbs, wait 15 minutes and test again. And if you're still low, eat another 15 carbs, right would be the next thing. And yeah, and now hopefully, you know more and more people but so is so I guess here's the question, if you don't have any good tech is 15 carbs 15 minutes still the way to go.
Jennifer Smith, CDE 8:49
From a safety standpoint, yes. Okay. Um, from a standpoint of even newer insolence are more rapid acting insulins that do have a little bit more definitive timeframe of action, it's a shorter timeframe of action. Again, I think that there's more consideration that you can still do even if you're just taking multiple daily injections and using a you know, a meter to check your blood sugar's fingerstick wise, you can still start out on the low end of treatment. If you're willing to go about a little bit more testing to evaluate the need for more. It will it will tighten your ability or it will tighten your range after treating you're not necessarily going to always need 15 grams even if you're blind with you know with no CGM data, let's say I in fact, I would say that many people could probably do well with five to eight grams of carb and not get into trouble with excessively high blood sugars. Again, that's outside of exorbitant insulin on board wording that kind of thing. But outside of that, I still think 15 is an overshoot. But it's a safe enough overshoot that it's definitely going to raise your blood sugar.
Scott Benner 10:11
So I want to kind of bring a couple of different thoughts in here. So first of all, if you're listening to this, because you are more more newly diagnosed, it's important to know that carbs will hit you at different speeds. So, you know, taking 15 grams of a baked potato for a low blood sugar is not going to be a good idea, right? You need fast acting easy to absorb simple sugars, things like that. You also have to be aware that if you have if you have, let's say you have enough insulin working, where you're low falling, and you're going to need 30 carbs to stop it. But you take 10 of a simple sugar, it could look to you even on a CGM, like the insolence just, it's just running through the sugar, the sugar is not even slowing it down, it is slowing it a little bit, but it might not be enough. So the speed, it's we're understanding glycemic impact and load a little bit helps with with stopping low blood sugars, you can eat a baked potato is going to take forever for your body to absorb, which is why the emergency gel for instance, gets rubbed on the inside of your cheeks, right gets absorbed very quickly. I know this is like a scary time for people. You know, so you're you're newly diagnosed, you're falling, here's how this goes. You do the 15 carbs, 15 minutes, eventually, you're happy because while I stopped the low blood sugar, and then you start seeing the next step and thinking well by now but my blood sugar's to 20. Now afterwards, I don't want to I don't want to stop a 70 and make it a 220. And by the way, some people are treating low blood sugars, and they're calling them low when they're first diagnosed at 110. They're like, Oh, no, I'm getting low, you know, right. And so then they see the next piece of it. And you're trying to make sense now of how do I stop this low blood sugar without creating a high one, I would even say to you, I would jump past that idea and say how do I get into a world where I'm not stopping low blood sugars all the time? Yeah, correct. Yeah.
Jennifer Smith, CDE 12:08
Right. And that's what we focus on. Even in education, we first look for lows, or percent of time, lows, are they frequent? Are they at a consistent time of day? Is there a trend to them, for example, and if there is, we go to meet those first, most people who want tighter control, they're actually much more worried about the highs than they are about the lows. But if we can take away a good number of the lows that are occurring in a in a pattern, we can also take away a lot of the highs because it's it's hard to not over treat, especially I think in the beginning when you're really learning about things, and trying to judge how your body is, you know, I guess reacting to stuff. And also how your brain is able to overcome the low and the symptoms and being able to tell yourself, well, I don't need that 15 grams, I feel these low symptoms, they're horrible. I'm only going to treat with this much
Scott Benner 13:11
right. It's all it ends up being that understanding the bump and nudge ideas from the Pro Tip series will help you understand this. In simple simple terms. If if you're standing on the sideline of a football field, you're out of balance and somebody's inbounds and they're just wandering out of bounds, you might just put your hand up and stop them without pushing them. But if they're running out of bounds, you're going to have to shove them to keep them in correct. And so if your blood sugar is and this is where having a CGM becomes really valuable if your blood sugar is 65, but it's super stable at 65, a few carbs and there's no active insulin, a few carbs might move you up to 90 no trouble. But there's active insulin or if the 65 is falling, then you'll need more carbs to counterbalance that. But in general, the blanket statement 15 carbs 15 minutes is either going to lead you to a life of bouncing blood sugars and not understanding what's going on or it's going to lead you to the the idea of like, Hey, I think there's more here for me to understand. Right, just running through people's statements again, the 1515 plan can be too many carbs for those 15 carbs was way too much for me. overtreating lows was a big problem in my management. You don't need 15 carbs for low is something I wish someone would have told me. I mean, you might, but it's not a hard and fast rule. Right. And then this person says that the 1515 rule was drilled into us. And so early on to combat minor lows. They're just doing it over and over and over again. They're seeing what's happening. But they can't, in their mind make the leap. They shouldn't be doing it or they should be adjusting it somehow because of how fervently it was it was drilled and recommended.
Jennifer Smith, CDE 14:53
Yeah, absolutely. And again, I think it's the biggest takeaway, right? Now is if you're using any kind of technology, I guess CGM specific or if you're just really, really on top of doing finger stick after finger stick, because that's what you're choosing to do, then you've got enough information, and enough accurate information to be able to say, in the past couple of weeks, I've done the 1515 rule. It's created this roller coaster up and down that I no longer want. What if I just treat with 10? Instead of 15? Right? What if I treat with eight instead of 50? Right? I mean, there, there's some navigation that eventually you're going to learn how to do your own self experimentation that say, Well, you know, this is what I'm gonna have to do, because that's clearly not working with 15,
Scott Benner 15:49
right? And you're gonna hear people say to you constantly, like diabetes is a science experiment, you're gonna figure it out, etc. That's all they mean. They mean trial and error. Don't do the same things over and over and over again. You know, once you see something and it proves itself out, trust it and do something different. Correct. Okay. So there you go. The 1515 rule, which is not really a rule it's just get says the people so many times people like it's a thing.
