Hi there, I'm a diabetes research nurse in New Zealand and writing a case study paper for a post grad course I'm doing. My subject with type 1 alluded to the fact that her blood glucose control was erratic most of the time no matter what she tried, however was very stable for about four days immediately after her period. It would appear there is not much research to confirm this, so wondered if this was a common phenomen related to the hormonal changes during this time. Would really appreciate your comments on your experience. Thanks
