Should I be on Metformin for prediabetes

Hi there,

I just wondered if I should be on Metformin for Prediabetes to stop me developing diabetes? (Which I feel is inevitable due to my family history)


Background story:

Type 2 diabetes runs in my family, all my 3 siblings have it, my father and everyone on his side of the family have it too. I've been on the prediabetes spectrum for a few years.

In 2018 I started developing tingling fingers and toes, as well as pain in my calf muscles whenever I ate foods with a high sugar content i.e. biscuits or chocolate. This happened within a minute or two of consuming the product. These symptoms would last a day or two.

I told my GP (At the time) about the issue about 1 year after I started getting the tingling/pain sensation and he said it "doesn't sound very nice" and it "doesn't sound anything serious", adding "sugary food was a good way to get fat".

Anyway, fast forward to today and I'm still getting the issue with sugary foods. As a result I very rarely consume anything with sugar in. Problem is a few months ago the tingling/pain sensation reemerged and hasn't subsided within a few days like normal. I'm stuck with it and GPs can't seem to explain my issue :-(

I asked a GP from an out of hours surgery about diabetic nephropathy because these symptoms are affecting my sleep and asked if could I get it as a prediabetic. The GP said I would need to have untreated diabetes for years to get nephropathy? No GP I've spoke to has seemed to know what's causing it or given any advice on how I proceed from here.


So, my questions are this:

1) Should I be on Metformin as a preventive measure considering most of my family have Type 2?

2) Can I still get/develop nephropathy despite only being classed as prediabetic?

3) Has anyone else had the pain in calf muscles and tingling in fingers/toes a minute or two after consuming sugary food?



Much appreciated, thank you.
I doubt I'll be very helpful as others have come up with good stuff already... B vitamins could well be the issue, as well as lack of magnesium (calves). You got your HbA1c down somewhat by starving yourself and upping fruits, which isn't the preferred method: lots of fruits have a large amount of sugar, so while you were starving yourself on one side, you were putting more bad things in when you did eat. (Fruit may be stuffed with vitamins, but they contain lots of carbs too, alas. :( ). https://www.diabetes.co.uk/forum/blog-entry/the-nutritional-thingy.2330/ might help a little when it comes to finding some balance, and might help your family too. Low carbing is quite do-able and while fasting can be part of that, going hungry doesn't need to. The difference between fasting and starving: one will assist in getting weight and blood sugars down while eating nutrient dense food when you break your fast. The other'll get you malnourished and miserable. So its a bit of a balancing act, but once you get the hang of it, it's easy. And if cookies sometimes are enough of a temptation to accept days of pain, it may be time to learn how to make low carb cookies, keto fat bombs and the like. Check out dietdoctor.com and google for how to's. Very good, but no nasty blood sugar effects. Metformin isn't a cure-all and you can easily get your blood sugars more thoroughly into the normal range through diet than through medication. Usually when you rely on meds to take care of your blood sugars for you, and keep eating the standard western diet, the condition is progressive. With a slight change in diet, it doesn't have to be. And even reversable. (Depending on how you look at it. In two months I'll have been a diagnosed diabetic for five years. I always will be one, and I accept that. But I'm a-symptomatic and have no complications nor medications whatsoever. I call that remission. If I eat cake though.... Not good. And that's just something I'll have to live with.)

One more thing: there are a bunch of different things besides diabetes that can cause discomfort in the extremities. As was mentioned before, B12 deficiency (and it may be worth noting, metformin also inhibits the uptake of B12, so if that's the issue it'd likely make it worse!), magnesium deficiency, but other stuff too... Has your thyroid function been checked recently? I had to switch my thyroid meds around yesterday for a blood draw and man, my feet are burning this morning! Try and get screened for just about everything. Just focussing on prediabetes might be narrowing the field too much and the problem could well be very fixable, if someone'd just bother to test you properly and broadly.

Good luck!

yep, it came down from 44 to 40 which I was happy about. Unfortunately the pain/tingling has stuck around. The thing about the 40 blood test result is that was fasting, whenever I eats food I'm getting 9-10 on the meter reading 2 hours post meal.

I would ideally like to have one of those blood tests where you do a fasting test, then drink some glucose and then come back in two hours for another blood test. I know these tests aren't that practical but I feel it could through more light on my circumstances maybe?
That's an Oral Glucose Tolerance Test, I think. I've never had one, and never felt I needed one.

I did one way back prior to T2 official diagnosis and not quite sure why. It seems now it is used to determine issues related to pregnancy

It seems there are pathways if you are near diabetes but it’s about lifestyle changes rather then medication. Which I guess makes sense as diabetic medications have a cost component

https://www.england.nhs.uk/rightcar...40/2018/07/nhs-rightcare-pathway-diabetes.pdf

also NHS guidance is clear, prediabetes are not eligible to drugs as standard:

Of course, for type 2 diabetics they will try diet first also.

prediabetes or type 2 has many opportunities for dietary and lifestyle changes, as we have personal testimonies including mine.
 
I noticed a lot of my tingling and numbness all over my body seemed to lower after i started drinking a lot more water than i use to...and water helps you in lowering your BG numbers too....also i started taking vitamin B12 and that helped a lot also....

I'm slightly puzzled at the tingling so soon after ingestion of carbs, as I'd expect it take longer for one's blood sugar to rise. It does sound a bit like an allergy. And neuropathy doesn't have to be caused by diabetes. (And your symptoms don't have to be neuropathy)

I agree your bgs seem a little on the high side but really not massively so.

Have you had a full set of blood tests to rule out all the possible vitamin deficiencies etc?
