Assessment of Thyroid Function in Pregnant Females Attending SKMCH Muzaffarpur

Background: Pregnancy is a physiological state in which significant changes in thyroid function occur. Several factors contribute to these changes. These factors could contribute to thyroid dysfunction during pregnancy especially when hormone levels undergo significant adjustments. This study aimed to assess thyroid function among pregnant women, tracking variations in thyroid-stimulating hormone (TSH), free thyroxine (FT4), and free triiodothyronine (FT3) levels across different trimesters. Methods: A observational study was carried out on 90 pregnant women attending the Obstetrics Outpatient Department at Sri Krishna Medical College and Hospital, Muzaffarpur from August 2023 to July 2024, were invited to enroll in the study. At the end of the study, the blood samples were assessed for free T3, free T4 and TSH Levels. Results: This study revealed that most of the pregnant women had normal thyroid functions (51%), while subclinical hypothyroidism (38%) was the most prevalent disorder followed by Clinical hypothyroidism (7%) and hypothyroxinemia (4%). Conclusion: The most prevalent pattern of thyroid dysfunction in pregnant women was subclinical hypothyroidism. These findings highlight the importance of early thyroid function assessment and monitoring throughout pregnancy, underscoring the need for routine screening protocols to mitigate potential risks to both mother and child.
