The Impact of Pregnancy and Parity on Type 1 Diabetes Complications

Abstract

Background: The potential influence of pregnancy and parity on the risk of chronic diabetic complications is a matter of great concern and constant discussion. This aspect seems relevant and should be the subject of thorough discussion with the woman planning childbirth.

Introduction: Current data concerning the impact of pregnancy and parity covers primarily retinopathy and nephropathy, while the aspects of neuropathy and macrovascular complications are unsatisfactorily documented. Majority of studies focus on single complication only, while the number of papers assessing this problem in a complex setting is limited. The available body of evidence concerns mainly the short-term impact of pregnancy on diabetic chronic complications while the data concerning the longer perspective are scarce. Moreover, the results found in the available literature are conflicting. The aim of the study was to summarize all available data concerning the longer impact of parity on the chronic complications in the women with type 1 diabetes.

Methods: PubMed database has been searched between October 2013 and September 2018 and all relevant papers were selected. This review summarizes data on the impact of pregnancy and parity on chronic complications in type 1 diabetic women.

Results: Current data assessing this matter in a complex way are limited, and the available results are controversial. It seems however that pregnancy itself may rather influence pre-existing diabetic complication than affect risk of its development. Additionally, evidence suggests that any deleterious changes appearing during pregnancy are transient and tend to remit after delivery.

Conclusion: It seems that neither pregnancy nor parity affects the risk of diabetic chronic complications in the longer perspective.
