Hi River Rat Sam
Same thing happened to me in the first few days of my low carb diet, when you eat less carbs your body burns fat. This creates keytones. My blood sugars dropped to 4-6mmol each time I tested and I was very happy, but when I checked for keytones it was ++ a dark purple.
I was so worried and started being sick so I went straight to A &E, as i had ketoacidosis last year and it was awful, 3 days in hospital. Keytones and high blood sugars are BAD!! however ketosis and low blood sugar apparently are not too much of a worry (according to the doc at the hospital :think: ), turns out i was suffering from gastritis and i was dehydrated hence the high keytones, ive been fine this week, no keytones.
You need to get this checked out, as the last thing you want is ketoacidosis, when the blood starts turning acidic. might be worthwhile ringing your diabetes support team, they might suggest popping to the hospital, they will do a blood test taking the blood from your wrist to check how acidic it is. its not too bad
but please bear in mind i am type 1 and don't know what difference this is for type 2 and i'm no doctor!!
I would suggest starting to drink water/squash to try flush out too. Hope you get sorted soon
**and when i say squash.. i mean sugar free!! no hi-juice etc
