Metformin Experiment

Hi All,

Hope everyone is managing well.

I had a cat scan last week so my doc told me not to take Metformin (I've been taking 1, 500mg twice a day) one day before and two days after the test, so I thought I'd try an experiment. <Doc doesn't know about it>

I also decided this would be a good time to start really eating low carb to lose weight, and to try to keep my blood sugar in check. I figured I was already going 3 days without it, so why not push it a week or so and see how it goes. Of course, if my results were high the plan was to go right back on the Metformin immediately.

Since last Monday (Feb 7) I've been eating about 25 carbs a day (give or take) and testing my fasting blood sugar first thing every morning, and my results went something like this:

131 - day i started
128
123
113
109 - later that day i fell down stairs, injured knee, bruises evrywhere.
134 - perhaps this result is due to the fall and the stress/worry.
123 - Next day heading back downward.
116
113 - this morning


I know it's just been a week and most likely eating low-carb has a lot to do with it as well, but I figure I'll keep riding this out and as long as my numbers stay relatively fine, I'll stay off the Metformin.

But, this begs the questions....

Is it harmful to just stop Metformin? (I haven't noticed anything so far)

If I can keep my numbers as they currently are, or even better (lower) should I stay off it?


Been on MF for a year now and frankly the side effects have been awful for me - constant diarrhea, frequent bathroom visits, and hot flashes. The funny thing is my numbers were around 120 - 140 while on it, and while off the medicine my numbers may even be lower. Time will tell I guess but my goal is to get off the medicine and manage my blood sugar with just eating low carb, losing weight, and exercising if possible.

Does this sound reasonable, or is just wishful thinking?

I welcome all opinions and/or advice.

My guess is that the strict low-carbing is what is bringing your numbers down, because there's still a fair amount of met in your system & it works especially well when used WITH low-carbing. It isn't dangerous to just stop taking it but it takes a few weeks to build up in your blood stream & it takes a few weeks to completely disappear.

But after 2-3 more weeks, if you can maintain lower without metformin, more power to you - especially since you get the side effects (did you ever try metformin extended release? The XR version usually reduces the side effects). The dosage you were taking is pretty low anyhow.

I also have no doubt that your fall is what caused that spike to 134! That must've been scary. For years I've descended stairs one step at a time, and I don't move to the next one until both feet are firmly planted on one step!
Everytime I call him for my test results it takes him 3 days to call me back, but I'm not sure if that's typical or not.
It may be typical, but it ain't right! :mad: In this day & age of EMR, those lab results could possibly hit the doc's office within an hour of the blood draw. Somebody's sandbaggin' us!
