As some may recall, I was diagnosed with B12 deficiency back in late September. I gave up taking Metformin temporarily mid September because I was having a flare up of diverticulitis and I thought it might be exacerbated by the Metformin, even though it was the SR variety. I decided to give it up altogether when I had the B12 deficiency diagnosis as it can block absorption of the B12. Anyway, I had the 6 injections of B12 and I felt soooo much better. I was no longer dragging my feet when I walked (that had caused some falls as I would trip over the least small obstacle, such as a paving slab raised by barely an inch more than it's neighbour), I was not suffering insomnia, even though I was stressed out at that time I was sleeping like a baby. I no longer had leg pains. Anyhow, time wore on and about the end of the first week in December symptoms of B12 deficiency started returning, night cramps, insomnia etc. I got another injection on 5 Jan and things improved - a bit - but I didn't feel anything like as well as when I'd had the 6 injections.
In addition to all that, I started piling weight on... by Xmas I had gained 4 lbs and even though I was quite controlled over Xmas - no chocolate, one small helping of pud and really have been eating my normal diet, but gained 2lbs and since I've gained another 3 lbs - so a total of 9lbs. Simply (I think) because I have my appetite back and I am eating a full plate of dinner instead of eating about 1/3rd of the plate and losing interest. Plus, I've had to increase my insulin doses... I am putting the same amount into my pump which used to last 6+ days and now it's barely lasting 5. I have had to raise basals a fair bit and also ratios, but I am still having FBGs in the 8/9 region and sometimes over 10. So that's all contributing.
This week I spoke to the GP who said "maybe get a blood test at 10 weeks", but from what I read the blood test is skewed if you've had B12 supplements in the last 4 months. I asked about the Metformin issue and she said she'd get the nurse to speak to me about it. The nurse phoned me (she's far more clued up than most surgery nurses) and said Met didn't always block B12 absorption in everyone and it could be caused by my own system, so go back on the met but ramp up slowly. That's fine, I am now having to reduce basals from about 11pm after 2 hypos 2 nights running at 1.30 am. Just don't know where to turn with ratios/basals. Anyone got any ideas?
Hmmm as I type this it has occurred to me that perhaps I should ask to see the DSN at the clinic. Basically I think I just needed a bit of a rant... I am so p*ssed off at the weight gain as I am heavier than I have ever been in my life and it's so blooming hard to lose it. All the same, if anyone has any insights I'd be grateful.
