The latest reports of the World Health Organization (WHO)  indicate that in 2005, approximately 1.6 billion people were overweight and at least 400 million adults were obese, a major contributor to global burden of chronic disease and disability. Increasing rates of overweight/obesity among pregnant women are of significant public health concern with various implications for prenatal care and supervision of delivery. Therefore, the present study is to determine the adverse materno fetal outcome in overweight and obese women delivering singleton babies. Obesity has become a major health problem all over the world in endemic proportions and it is rising worldwide including in women of reproductive age. According to WHO World statistics Report 2012, globally one in six adults are obese and nearly 2.8 million individuals die each year due to overweight or obesity. Due to the increased risk of morbidity and mortality, Obesity is now recognized as a disease in its own right. WHO describes obesity as a ‘killer disease’ comparing it with HIV. Obesity is expressed as the body mass index or Quetelet’s index. The rate of obesity in pregnant women is rising and consequently obesity related problems. Maternal overweight/obesity has been reported as a risk factor for various antepartum, intrapartum, intrapartum, post partum complications like gestational diabetes mellitus, gestational hypertension, pre eclampsia, antepartum hemorrhage, associated with risk of post-term delivery and greater need for induction of labor (IOL), postpartum hemorrhage, operative vaginal delivery, increased emergency cesarean delivery and total operative time, increased blood loss, multiple epidural placements and complications from difficult or failed intubations, increased infection rates, and prolonged hospitalization and neonatal complications like fetal macrosomia, shoulder dystocia, respiratory distress, NICU admissions and foetal anomalies like neural tube defects and still birth. Obesity is detrimental to the accuracy of obstetrical ultrasound examination. Obesity and hypertension are common co-factors in causing peri partum heart failure. The increased risks of complications in overweight/obese women during during pregnancy and delivery coupled with rising epidemic among women emphasise the need for specialists involved in identifying and treating overweight/obese women and to be aware of the risks, complications and their management. Second-trimester dilatation and evacuation was reported to take longer and be more difficult in women whose BMI was 30 kg/m2 or greater. Obese women are less likely to breast feed than normal-weight women. Postpartum depression was significantly increased in obese women in relation to the degree of obesity. Overweight and obesity are emerging problems in India. 13% of women and 9% of men are overweight or obese. The NFHS-4 (2015-16) of India  reports an increasing prevalence (20.7%) of overweight or obesity among women aged 15 to 49 years (ranging from 31.3% in urban areas to 15% in rural areas) compared to 12.6% in 2005-06 that the percentage of overweight or obese women among NFHS has defined malnutrition as a state of being either underweight or overweight or obese. Taking this definition into regard, 28.9% of malnutrition in urban areas is due to overweight or obesity and only14.6% of malnutrition is due to overweight or obese in rural areas 
Aims and objective: Compare the of Feto maternal out come in obese and normal weight pregnancy Methodology: This Prospective comparative study was conducted in the Department of Obstetrics and Gynecology, in Vanivilas Hospital and Bowring and Lady Curzon Hospital associated to Bangalore Medical College and Research Institute, Bangalore during December 2016 to May 2018. In this study, 75 pregnant women with BMI>25kg/m2 and 75 pregnant women with normal BMI 18.5 -24.9 kg/m2 were included. After taking informed consent, detailed history was elicited and detail physical examination, routine investigation were conducted patients are followed till delivery.
Results: Incidence of hypertension, gestational diabetes, preeclampsia, induction of labor, PROM, Mode of delivery, ceaserian sections, SGA, nicu admissions are higher in obese patients than non-obese patients.
