New research to be published in BJOG: An International Journal of Obstetrics and Gynaecology has found that women who are overweight from the age of 36 and those who are obese from the age of 43 and 53 have a higher risk of hysterectomy than underweight and normal-weight women. The study, from the Medical Research Council National Survey of Health and Development (NSHD), is one of few to examine weight over time and subsequent hysterectomy risk.
