Introduction: Obesity is a growing health problem worldwide. The World Health Organisation (WHO) defines obesity as abnormal or excessive fat accumulation that may impair health with body mass index (BMI) of 30 kg/m2 or more as obese among adults. Aims: The primary objective of the study is to determine the effects of obesity in pregnancy. Materials and method: The present study was an observational study which was conducted from January 2023 to February 2024 in the Department of Obstetrics and Gynaecology. 300 patients were included in this study. Result: In Obese, 13 (8.7%) patients had Shoulder dystocia which was statistically significant (p=0.0002). NICU admission in non-obese and obese women was 9 (6.0%) and, 27 (18.0%) patients respectively, which was statistically significant (p=0.0013). Conclusion: This study demonstrates that maternal obesity significantly impacts fetomaternal outcomes, increasing the risk of gestational diabetes, hypertension, preeclampsia, preterm birth, macrosomia, and neonatal intensive care admissions. The findings highlight the importance of preconceptional counseling and weight management for women of childbearing age to mitigate the risks associated with obesity during pregnancy. Targeted interventions to address maternal obesity can improve both maternal and neonatal health outcomes, enhancing the overall quality of care in obstetric practice.
