Group B streptococcus is a type of bacterial infection. This bacterium naturally lives in the gastrointestinal tract and is present in the vagina and/or rectum of about 25% of all healthy, adult women. Once you have this bacterium it does not mean you will always have it, and it can come and go. Most women who are colonized with group B strep do not experience any symptoms, and normally this is not a big deal. It can create some complications for you when you are pregnant and can cause some serious complications if it is passed to your baby. It has become standard practice to test all expecting mothers between weeks 35 to 37 for group B strep. This episode covers what is involved in the testing, how group B strep is treated, and how you can reduce the risks to your baby. This episode also explores some research on what you can do to decrease your risk for group b strep during pregnancy and prevent the possibility of ever becoming colonized.
