Diagnosed t2 a couple of years ago take atorvastatin, aspirin, metformin 1 od, and vitamin D. I read in the Times that vitamin D was proving to be an asset to diabetics as it helps the insulin use up the blood glucose better. My annual check up in April showed that my general reading had dropped from 6.7 to 6.6, my weight has dropped a little. I have since April started exercising far more (I now walk at least 45 minutes every day) and watch my diet as best I can. I do not do the low carbs diet, just watch the sugar intake. Today whilst cleaning the car I suddenly felt really dizzy (4 hours after breakfast) I took my blood sugar and initially it came up as LO (see your doctor and do what he recommends) 2nd time immediately after that it read 1.8., I had a cup of hot chocolate, a couple of biscuits and a banana and felt better then, blood came back to 4.5. For the past month or so my blood readings have never been above 5 and I am wondering whether it is the vitamin D, the exercising or diet has really altered the levels. What is your opinion on stopping the metformin? I am wondering if I need it now with the levels being so low whether they would stay that way with just the exercise, diet and the all important Vit D.
