Bacterial vaginosis (BV) is one of the most common causes of vaginal symptoms in women, yet it’s often misunderstood.
BV occurs when there is an imbalance in the normal vaginal bacteria.
Instead of the usual protective lactobacilli, other bacteria overgrow.
Common symptoms may include:
• thin gray or white discharge
• a “fishy” odor
• mild irritation or discomfort
Some women have no symptoms at all.
In midlife, hormonal changes can increase the risk of BV.
As estrogen declines:
• vaginal pH increases
• protective lactobacilli decrease
• the vaginal environment becomes more susceptible to imbalance
BV is not a sexually transmitted infection — but it can be influenced by sexual activity, douching, and changes in the vaginal environment.
The good news is that BV is treatable.
If symptoms are recurring, it’s important to look at the underlying factors — including hormonal changes.
Vaginal health is an important part of overall health
