In my second blog I am going to discuss about the influence of bariatric surgeries on fertility based on some case studies.
Obesity shows many negative effects on the reproduction. Some adverse effects of obesity include irregularities in the menstrual cycle, anovulation, miscarriage and infertility in women. And in men, low testosterone levels, reduced spermatogenesis & erectile dysfunction are observed.
Obesity during pregnancy may cause several fetal abnormalities such as neural tube defects, spina bifida, cardiovascular anomalies, septal anomalies, cleft palate, cleft lip, anorectal atresia, hydrocephaly, and limb reduction anomalies. Also obesity during pregnancy may cause preeclampsia, gestational diabetes, thromboembolism. 
A research was carried out to study the outcome of complications after bariatric surgeries. During their study they observed an improved fertility and a reduced risk in obstetrical complications, gestational diabetes. The incidence of intrauterine growth restriction (IUGR) found to be increased. However, no conclusions were made on miscarriage. Anemia was profound due to deficiency in major vitamins, iron and other salts.
Thus though bariatric surgeries may cause problems such as malabsorption it is advantageous especially in the aspects of fertility.
