Has Anyone Had The Experience Of BG Going UP After Taking Metformin And A Meal? Last Few Days Readings Are Up(above Fasting Levels)

A DiabetesTeam Member asked a question 💭
Gorham, ME

When I first started Metformin, my fasting BG levels were "fine"...in the accepted range and after the meds readings were still good...went down by 3-5 points. The last few days have seen the numbers rise with today's reading at 163 and then 200 2hours after meds and meal. What's up with that!?

Not sure where to put this, but first I need to apologize...I have been off the grid so to speak for a bit. I want to let everyone know that my doctor had no clue why my BG levels were going up on the Metformin so no satisfaction there. At any rate, my A1c came down (from 6.9 to 6.5) and fasting BG levels are now ranging from 129 to 99, but mostly around 111. Now this is WITHOUT the Metformin (I simply quit taking it). Doctor said I only need to test once a day or even every other day now. I have a theory that the major part of this whole thing was caused from the steroids I had to take when in hospital for pneumonia back in March (when I first noticed that BG levels were so high). It has taken quite a while, but now levels are back where I am used to seeing them. Frankly, my diet hasn't changed greatly, tho' it HAS changed some (I am eating less sugared things and for the most part, I cook everything from scratch as I always have). The dietician was impressed with the food /meal log I took with me to see her. We did agree that I need to drink more water, but for the most part, what I have been doing is good. So for now, at least, it looks like things are under control and I am greatly encouraged.

More people die from the complications of high blood sugar so I would argue thats more dangerous. Most of us can combat a low in the matter of a minute whereas it can take literally years to figure out how to get out of the highs

Marilyn maybe your blood sugar went down a bit because your pancreas started working a bit harder, especially if you ate something. You didn't say whether you had your eggs before you checked.

I think you will find Liz, that by stopping your metformin you will be getting higher numbers. This will take a week or two to show as Metformin is something that is in the blood continually, rather than a 'meal time' medication. It takes several weeks to build up to optimum level in the blood and the same to decrease it's value in the blood. It works to prevent the liver from spilling excess glucose into the bloodstream when it 'thinks' you are going lower. You might try it and find out, for sure though. Up to you if you want to take a few weeks out of your normally good cotrol to try this. It would satisfy your curiosity for sure, and maybe prove that what I have read is not always correct for everyone. Be interesting....

Your sugars will go up not matter what meds you are on @A DiabetesTeam Member. That's what everbody's body does, even non-diabetics. The trick is to be under certain numbers at the two hour mark. If you are not...then you have ate too many carbs.
Metformin has some side effects that typically last a week or two before evening out...frequent trips to the bathroom and stomach upset. But the med is designed to be taken with a meal. Try taking it halfway through your meal so it has lots of cushion for digestion.
