Abstract

Introduction: Pregnancy induced hypertension (PIH) is an important cause of maternal and fetal morbidity and mortality affecting 5-10% of pregnancies. PIH is more frequently associated with elevated TSH (Thyroid-stimulating hormone). Thyroid dysfunction plays an important role in the development of gestational hypertension. However, this relationship remains unclear. The study was performed to evaluate the thyroid status in pregnant women with PIH and normal pregnant women.

Methodology: This was a hospital based observational case control study done in Dr M K Shah Medical College, Ahmedabad. Total 100 pregnant women were included, out of them 50 PIH women were included in the case study group and 50 normotensive healthy pregnant women were included in the control group. After taking written consent, thyroid profile (TSH, free T3 and free T4) were measured in all 100 subjects.

Results: Women with PIH had higher TSH levels and lower free T3 and free T4 as compared to normotensive pregnant women. There was a significant association between hypothyroidism and PIH cases. There was a significant positive correlation between TSH and systolic BP (r=0.42) and diastolic BP (r=0.52).

Conclusion: PIH women are at greater risk of decreased thyroid function. Therefore, PIH women should be monitored for thyroid levels regularly.
