Message: <blockquote data-quote="Chronicle_Cat" data-source="post: 2013510" data-attributes="member: 486327">4.3 is normal blood glucose. 4.0 and above is normal blood glucose. Unlike Type 1s, most of us with Type 2 don't get hypos because we still produce some insulin. The exception is the Type 2s who take insulin or insulin producing drugs (NOT metformin) which need reduction because of low carb eating. Most Type 2s don't have to worry about a reading of 4.3. I would not correct 4.3 but I  if I was fasting. I would stop an extended fast with that reading. (I keep my blood glucose 4.0 and above, within the normal range.)Being on metformin and low carb/keto doesn't put you at risk for hypos (unlike insulin or some meds that produce insulin). Metformin doesn't cause you beta cells to produce more insulin, instead prevents the liver from making excess glucose and makes your muscle and fat cells more sensitive to your own insulin.You may get some false hypos where you have the symptoms of a hypo but blood glucose in the normal range  (4.0 mmol/L and above) - always check if you think you have a hypo. Some Type 2s get false hypos when their numbers first start to come down because their body has become used to higher numbers. Unlike real hypos, these are not dangerous and should NOT be corrected and they usually go away in a couple of weeks as your body adjusts to newer, normal numbers..</blockquote>
