So, just what is bacterial vaginosis, and how do you get it? That's the set of questions we'll be looking at in this post.
Just a note beforehand. The CDC classifies bacterial vaginosis (BV) as a sexually transmitted disease. However, that is not necessarily the case, for a virgin can also contract BV (and you'll see why in a moment). Although it may be spread by sexual activity, as it is bacterial in origin, it is not caused by it.
What is Bacterial Vaginosis?
BV is a common vaginal infection among women. It's caused by the balance of bacteria normally present in the vagina becomes unbalanced -- there aren't enough "good" bacteria to keep the "bad" bacteria in check.
This is much the same situation as with many kinds of bacterial infections. Bacteria is present all around us, both on and in our bodies. Normally our bodies can keep it all in balance, but circumstances can cause bacteria to multiply beyond their normal range. When this happens, there is an infection.
And that leads to the next question -- what exactly causes BV?
What Causes BV?
This is a tough one, because you can't point to something and say, "Ah-hah, that causes BV!". Instead, it seems to be a combination of factors.
So let's start with the obvious; anything that introduces bacteria into the vagina can be suspected (including items like tampons, douches and the like). It's a fact -- bacteria are on everything.
However, that isn't really enough. There has to be some sort of irritation for the bad bacteria to grab hold of. For example, a douche that is too strong, or has too much scent (and your skin is sensitive to scent) can cause an irritation.
Your underwear may play a role as well; thongs are thought to be a contributing factor to BV, and especially recurrent BV. If you wear thongs regularly and have problems with BV, try switching underwear and see if it helps you.
BV is also common among pregnant women, and there's no clear-cut cause there, either. It's supposed that fluctuating hormones could put the body (and including the vagina), off-balance. This would allow the bad bacteria to proliferate.
Another possible cause is any birth control method (like an IUD) that can cause an irritation.
Don't worry about possibly getting bacterial vaginosis from a toilet seat, in a swimming pool, from bedding or just touching objects around you. You won't.
So, I hope I've answered your question, "what is bacterial vaginosis?" and to some of the possible causes. Now here's a page for you with symptoms of bacterial vaginosis. Do you really have it?
