How do probiotics taken orally actually reach the vagina?

All women have heard that taking acidophilus whilst taking antibiotics is a measure taken to prevent yeast infections. How is it that the probiotics, taken orally, actually affect/reach the vagina?? THANKS!!

Ok how do they naturally gravitate to where they are needed. You have not answered anything here. First at all probiotic are bacteria. Bacteria can not enter the blood stream otherwise you would have bacteremia. So As you ingest the probiotic it has to come out through only one way out of your body. It can not enter your urine as it would breach the blood to enter the kidneys and to be filtered out. So there is only one way out and that is through stool. So small amount of healthy bacteria such as lactobacillus remains at the perianal area where its quit moist. The daily activity eventually gets it to the vagina. Where it can reproduce in larger quantities. It has to come out in the feces. The reason why e.coli does not live in the vagina its because of competition with lactobacillus and other beneficial bacteria. Its natural selection on microscopic level.

Hi Anon

Thanks for your question and welcome!

The kinds of probiotics taken by people to help their digestive tracts and reproductive organs naturally grow in these areas, so when taken orally, they naturally gravitate to these areas of the body where they naturally belong. Since certain antibiotics can leave a person open to yeast infections, pro (as opposed to anti) biotics can offset this. So as the antibiotic gets rid of the bad bacteria in our bodies, the probiotics keep the good bacteria in.

I hope this helps you!

Saying that probiotics "naturally gravitate to where they are needed" is not scientific or helpful. Your response did not address in the slightest how oral probiotics travel to the vaginal canal.
