Preconception counseling in women with pre-existing diabetes mellitus: evidence-based strategies to improve pregnancy outcomes

Pregnancy complicated by pre-existing diabetes mellitus is associated with increased maternal and fetal morbidity. Hyperglycemia during the periconceptional period significantly increases the risk of congenital malformations, spontaneous abortions, and adverse perinatal outcomes. Preconception counseling plays a vital role in optimizing metabolic control and minimizing complications before pregnancy occurs. The aim of this review is to summarize current evidence and highlight practical clinical strategies for optimizing pregnancy outcomes in women with pre-existing diabetes. A literature search was conducted using PubMed and Google Scholar for articles published between 2000 and 2024 using keywords “preconception care,” “diabetes,” and “pregnancy outcomes”. Relevant literature was identified from international clinical guidelines and peer-reviewed publications using standard database searches. Optimal preconception care includes achieving strict glycemic control, screening for diabetic complications, reviewing medications, initiating folic acid supplementation, optimizing body weight, and ensuring effective contraception until glycemic targets are achieved. Multidisciplinary care involving obstetricians, endocrinologists, dieticians, and ophthalmologists is essential for comprehensive management. Evidence suggests that structured preconception programs significantly reduce congenital malformations, perinatal mortality, and maternal complications in diabetic pregnancies. Despite this, many pregnancies in women with diabetes remain unplanned, emphasizing the need for improved counseling and awareness. Early identification and management of reproductive-age women with diabetes should be incorporated into routine clinical care. Implementation of standardized preconception counseling protocols can substantially improve maternal and fetal outcomes.
