Wearing Lingo CGM (continuous glucose monitor). See what it says about a “night spike”:
The app allows you to search for information, but it has nothing about “night spikes”.
Anyone ever heard of this term?
That “spike” went from about 80 to about 100. I have no idea what could cause this.
Although it’s interesting to see the (slight) elevation between midnight and 2am [well before the onset of a typical “dawn effect” begins to kick in, with its signature gentle sloping rise until wake-up time], I would not call what’s seen in the graph as anything like a “spike.”
On the contrary, it seems your body has a nice self-regulated pattern underway with no material excursions. It looks like a well-controlled round of gluconeogenesis during sleep while your body is repairing/restoring physical and cerebral functions (which does require some level of glucose).
At this point are you concerned - or just curious?
Never heard that as a term, but our sugar can bounce all over the place in the night hours. I’m with you, 20 as a “spike” is a little dramatic, but all those apps are also geared towards people who know nothing and learning, so it’s got to say something I guess.
I almost completely stopped caring about any one number and way more concerned with my averages. I’d rather have an actual spike from 85 to 180 that I recover from in an hour than go from 85 to 140 and spend 4hrs fixing it.
Thanks. I think I’m concerned because it was not “normal” for me. This was May 2019:
That’s almost 30 days of data. Then if you look at a few days of data:
Meanwhile, if you look at yesterday’s:
From 83 to 115, all at night with no eating. And I ate a keto meal, late though (around 8pm). (The 12 was from a Mother’s Day meal with some quiche and a small amount of a potato/meat dish.)
Granted, the spikes aren’t “huge”, but I have over a year’s worth of data from a few years ago, with zero spikes at night.
I think it’s the Jardiance I have to take. I believe it’s causing lower blood sugar, and then (something in?) my body is reacting to increase the blood sugar.
Here’s another one, this one was my wife’s and I’s 20th year anniversary dinner at a fancy restaurant:
I can understand the 8 at around 6:30pm, as I had bread, dinner, then we split a dessert. But the dip to 70 then a peak of 107 doesn’t make sense.
My only conclusion is that Jardiance is causing low blood sugar, then something is reversing that. Unfortunately, I don’t know anyone else on Jardiance who is also keto with a CGM.
Wouldn’t the dip to 70 reflect the responsive effects of a release of insulin to reduce serum glucose from the meal with bread and dessert? … With the subsequent early rise (fairly modest) being the onset of GNG beginning the dawn effect?
That’s theoretically possible, I guess, but I’ve never seen it. I don’t have too much that’s close to this date, but this was from 2017 (Thanksgiving):
The 7.0 on Wednesday was from 2 pieces of ice cream pie. The highs on Thursday were from Thanksgiving meal (9.8, the hump after that), and the 8.2 was more Thanksgiving dinner. But see how flat the blood sugar is overnight?
That was on completely different drugs. This was what I made from my last Lingo:
This is on Jardiance. They say that Jardiance lowers blood glucose:
But I can’t find out what that means for blood sugar, insulin, etc. If you’re peeing out glucose, for instance, what happens to insulin? I have no idea, and I don’t think anyone else does either.
Most people lose weight when they go on Jardiance, but that’s because they are diabetic (and Jardiance lowers HbA1c by only 0.7, which is paltry). But for someone like me who has a low HbA1c to begin with, if I lose 0.7 in HbA1c, is that good? Bad? Unfortunately, I didn’t take HbA1c before I started the drug. My HbA1c is 5.1 a few months ago. I personally found myself more hungry after starting Jardiance.
Anyway, I have one more day on my last sensor. I’m giving up after that, because I can’t change anything.
All very curious. And you certainly have done superbly at gathering the data.
May I ask the reason you are taking Jardiance? Perhaps that might be relevant to what you’re seeing?
