Researchers recently looked at the risks of losing a baby after amniocentesis and chorionic villus sampling (CVS) when a mother is obese. They found that if a mother with a BMI of 30-40 had an amniocentesis or a CVS procedure, that there was no increase in the risks to the baby. However, if a mother had a BMI of over 40.0, there were increased risks found with an amniocentesis, but not CVS.
While there is still a risk of losing a baby because of the invasive nature of both of these tests, the risk is very small and for most women, weight does not increase that risk. This may allow more mothers who would choose to have genetic testing done to do so without added worry of increased risk. And if you happen to want genetic testing and have a BMI over 40.0, perhaps a CVS test is better for you. This should be one of the many questions that you would ask before having genetic testing done.
What were you told about your weight and either amniocentesis or CVS?
