Consensus statement on diabetes control in preparation for pregnancy

In reply: Walters and Senaratne raise two important points — that specific preparation for pregnancy is the exception rather than the rule, and that many people with diabetes (including women of childbearing age) demonstrate poor glycaemic control.

As a first step to improving this situation, we believe it is reasonable to set a goal. We sought to alert clinicians, especially those with limited experience in this area, to the importance of optimal glycaemic control in preparation for pregnancy. We hope that the consensus statement represents a “signpost” rather than a forlorn “cry in the wilderness”.

Many opinions were sought in developing the consensus statement. Some, for reasons similar to those given by Walters and Senaratne, thought the “HbA1c < 7%” goal too strict, while others believed it to be far too lax. In the end, we agreed to include this figure, with the proviso that the level of glycaemia should be the best achievable for each individual patient. We must educate women of childbearing potential with diabetes and their caring health professionals about the need for preconceptional diabetes control as part of their care. In some clinical circumstances, such as assisted reproduction, the timing of conception is actually determined by the treating doctor. In this setting, optimal glycaemic control should be a prerequisite for active treatment.
