Introduction: Diabetes Mellitus (DM) is a chronic disease characterized by hyperglycemia resulting from a deficiency in insulin production or its action. It is estimated that 1 in 10 adults live with diabetes worldwide, being a leading cause of death with a total of 6.7 million. Objective: To identify the adherence to self-care of women with previous DM who became pregnant and assistance from the multidisciplinary team to women with DM who become pregnant. Methodology: This is a descriptive and exploratory study, carried out from June to September 2021. The study sample consisted of women with a medical diagnosis of DM1 or DM2. Results: The study recorded 115 responses, among these (76) 66.1% already had a diagnosis of Gestational Diabetes Mellitus (GDM) and for this reason were excluded, leaving a total of (39) 33.9% responses. Conclusion: It was possible to verify that the reception of the team with the pregnant woman was efficient and helped in self-care, but some factors interfered in this process, highlighting the difficulty to adhere to an adequate diet and socioeconomic status.
