Weight affects pregnancy. Our governing body, the American Society for Reproductive Medicine, has recommended that women achieve a body mass index (BMI;; kg/m2 ) of < 35 prior to pregnancy. These recommendations come from extensive study of risk and reported complications to be known and associated with pregnancy.
It is fact that elevated BMIs are associated with increased anesthesia risks and pregnancy related medical problems (morbidities) like gestational diabetes and preeclampsia. It is known that these inflammatory conditions effect the embryo at implantation, fetal growth and the matrix in which this born child will manage metabolic issues as adults.
There is a difference in IVF stimulation. Women with elevated BMIs tend to require more stimulatory medications as the medication is distributed over the weight range. It is more difficult to assess follicular growth as ovaries may appear farther from the ultrasound probes on assessment. Retrievals tend to garner fewer eggs than age-matched controls.
Although infrequent, anesthesia complications do exist – inclusive of oxygen desaturation requiring additional airway maintenance, supplemental oxygen and possible increased risk of abdominal bleeding post-procedure. These complications involved the technical component to the stimulation and capture of the oocytes. Medical issues such as: hypertension, acid reflux, asthma, diabetes and sleep apnea only serve to potential the technical risk of the procedures.
