Do you want to get pregnant? Are you having problems with your excess weight?

A new study published by Human Reproduction in April 2011 reveals that obesity during the first months of pregnancy is strongly associated with fetal and infant demise even without the existence of other predisposing factors such as congenital anomalies and diabetes during pregnancy.

According to the researchers of this study, this is the first ever study to document the possible relationship between increased body mass index values and fetal and infant deaths. And they have discovered in their investigation that the optimum BMI for women in order to have a healthy pregnancy is around 23. However, as they have mentioned by clinical studies and researches are needed to further establish their findings.

In this study, the researchers gathered records of singleton pregnancies from 2003 to 2005 from five hospitals. They have discovered that obese women have a significantly increased rate of delivering a dead infant compared to their normal weighing counterparts. However, no excess risks were noted in women who are underweight or overweight. Among the obese women, no specific cause of infant death were seen except for a higher rate of pregnancy-induced hypertension or preeclampsia. However, the exact story how stillbirths and infant deaths happen is still beyond the researcher’s comprehension. Thus further investigation is needed in order to grasp the exact pathophysiology behind this problem.
