I have question.
My fasting numbers likes to be 120 all the time. (I did get a 96 yesterday, but today it was 116.)
I can't seem to get it lower and I want it to be 90 so I can pass the A1C better.
(I'm still new at this, and still have to do a confirming A1C)
You will probably see some see-saw numbers until they settle down. Once they do, if you are doing your part you will probably find you run in a reasonably tight range.
I typically run in the mid 90's and don't vary a whole lot. I have been a little over 100 now for the past 3 weeks (had a bit of stomach flu, then got a booster dose etc) so I am not surprised.
You can get to the same point when you will "know" just based on your fasting number if something is up (cold or infection coming on etc) because you will be running a little higher than normal.
So yes, do give it a few weeks. Once you are staying within about a 10 point range consistently you will know that things have settled in to about as good as they are going to get with your (current program).
Once they are settled then you can decide if you want to try and effect it a little more or you are happy with where you are.
For myself, I'm rarely in the 80's although it would be great (and really help the A1C) if I was more consistently. But I just don't figure the work (or meds needed) to get me down there are really "worth it".
Once you have decent control how far do you want to push it? That's the question you will have to answer for yourself. We have to remember to "live along the way" and not get so obsessed or go so overboard simply looking for a "better number".
I still get peeved if my FBS runs above 108 (the top of my range), but it does happen a few times a year. Just doesn't bother me enough that I'm going to either fret over it or undertake some plan to stamp it out completely - unless it becomes "common", I just take at as one of those "blips".
Sometimes in our quest for better control we almost forget "We have Diabetes" and sometimes our numbers are going to reflect that 😃
Blood sugar running around in our veins comes from two different sources.
First there is the food that we eat that gets metabolized into "after meal" sugars.
The second source is produced by our own bodies and is stored by the liver. It is released in response to various hormones ultimately directed by the brain.
It is this (metabolic) blood sugar that produces our fasting levels - so overnight after sleeping or anytime that we don't eat for more than about 5 or 6 hours (which is why skipping a meal might not put "dietary" sugar into our system, our own body will just do it for us).
While we have great control over what we put in our mouth (dietary sugars) we have almost "zero control" over how much sugar our own system releases.
Optimizing our metabolism - better diet, more fiber, more exercise etc will have a "somewhat slow" but long term effect on our fasting sugars but there is almost nothing you can do "today" to effect your fasting sugar tomorrow - it just doesn't work that way or that quickly.
If you are not too far out of hand (in total average blood sugars as measured by A1C) the Doc will generally give you some time to sort it out. If you "follow the rules" eventually (over months) your Fasting Numbers will settle in and reflect how well your lifestyle changes are working (or not working as the case may be)
That is also why there are two different (broad types) of diabetes medications.
There is Metformin and Basil (long acting) insulins to deal with problem fasting numbers and then the raft of others that all work against post meal numbers. And those from each group don't do much of a job of the other type of sugar that they aren't meant to treat - so metformin won't help with mealtime sugars and Rybelsus won't do much for fasting numbers (as an example).
In the first year or so after diagnosis, if your Doctor has half a clue they will try and determine "which" blood sugar sources are causing the challenges (if any) and medicate "that source" instead of just tossing a medication blanket over the whole thing and hope they find the issue that way.
Fasting Numbers under 126 are considered "just fine" but you obviously understand that if you can constantly break 100 that will go a long way to improving your A1C since fasting numbers should really form the "lower level" of our blood sugar range, so the lower (within reason) the better for overall control.
So do give it time to stabilize if you have made dietary changes. It could take weeks to see the benefit of any of those changes. Getting a little more fiber or foods higher in anti-oxidants into your diet, or supplements for, and/or adding in a daily probiotic can all help get your metabolism "tweaked" which will benefit your fasting sugar levels.
Then, if they still remain pesky, then Metformin is the gold standard treatment for them.
