Exploring Thyroid Dysfunction During Pregnancy: Implications for Anemia and Timing of Birth

Background: Maternal thyroid dysfunction during pregnancy has significant implications for both maternal and fetal health, with hypothyroidism linked to adverse outcomes.Understanding its impact on fetal development is crucial for prenatal care.This study, focusing on haemoglobin levels, examines the relationship between maternal thyroid dysfunction, particularly hypothyroidism, and fetal development.Methods: This cross-sectional study was conducted at Mc Gann's Teaching District Hospital, Shivamogga, and analyzed pregnant women with and without thyroid dysfunction-screening involved comprehensive assessments and thyroid function tests.Two groups were compared: thyroid dysfunction (Group 1) and normal thyroid (Group 2).Results: Differences were observed in comparing haemoglobin levels between pregnant women with hypothyroidism (case group) and normal thyroid (control group).In the case group, term births had lower Hb levels (10-10.9g/dL: 76%, 7-9.9 g/dL: 24%) than controls (>11 g/dL: 95%).Preterm births in the case group also showed lower Hb levels (7-9.9 g/dL: 86%) compared to controls (>10 g/dL: 87%).Conclusion: Maternal hypothyroidism is associated with fetal development issues, particularly preterm delivery.Anemia resulting from hypothyroidism may contribute to preterm birth.These findings underscore the importance of thyroid screening and management during pregnancy to optimize maternal and fetal health outcomes.Further research is needed to understand underlying mechanisms and explore interventions.
