ABSTRACT: Introduction: During pregnancy, physiological changes lead to increased thyroid activity. In some cases, this thyroid hyperfunction may become pathological. In Senegal, the most recent data on the prevalence of hyperthyroidism during pregnancy date back to 2003. Therefore, we aimed to determine the hospital prevalence, sociodemographic characteristics, and information regarding the need for contraception in this association in a hospital setting in Dakar. Methodology: We conducted a prospective and retrospective, descriptive study from January 1, 2018, to June 30, 2023, in the Endocrinology-Diabetology-Nutrition Department of the National Hospital Center (CHN) of Pikine. All patients followed for hyperthyroidism during pregnancy over this period were included. Results: Forty patients were included. The prevalence of pregnancy among women followed for hyperthyroidism was 2%. The mean age was 29.63 years. A family history of hyperthyroidism was found in 12.5% of patients. Among patients previously followed for hyperthyroidism, 52% reported not being informed of the need for contraception. The mean gravidity was 2.85 and the mean parity was 1.37. Primiparity concerned 35% of patients. The mean gestational age at the first endocrinology consultation was 14 weeks of amenorrhea. Conclusion: The prevalence of this association remains high in our setting. The results also highlight a lack of information regarding the necessity of contraception. Multidisciplinary collaboration and appropriate follow-up are essential, as they determine prognosis.
