Hi all I was diagnosed in July 2015 with B12 deficiency (apparently I was just under the 'normal' range but had all the symptoms including exhaustion, pins and needles in hands and feet, memory loss etc) I was originally diagnosed in 2012 whilst pregnant with my third baby as being B12 deficient and was given a loading dose but was told it was just a pregnancy symptom and wouldn't need to be followed up! Anyway fast forward to last year when I started getting the symptoms again I requested the blood test and it can back as being deficient! I was given 4 loading doses (and not the usual 6 as I had them when I was pregnant in 2012 apparently) since then I've been given 3 monthly doses and can safely say it has helped. The pins and needles have disappeared and my tiredness and memory fog isn't as bad. However I've started to notice that I've lost some weight since having the injections - is this normal? I've only lost half a stone and apparently my BMI is still OK as had a new patient health check but I don't think I've done much to contribute towards this weight loss? I was always around 9 1/2 stone and now can't seem to get above 8 stone 13! I have stopped drinking Coke and eating chocolate but only because I wanted to get rid of my bloated belly!! Has anyone else experienced weight loss after having b12 injections?
