An IIT Madras study reveals a substantial rise in C-section deliveries despite decrease in pregnancy complications. The findings were published in BMC Pregnancy and Childbirth. The study says prevalence of C-sections across India increased from 17.2 percent to 21.5 percent between 2016 and 2021. It shows 28 of 36 states and UTs exceeded WHO’s C-section 15 per cent upper limit.
