Since there is no primary cause for bacterial vaginosis, it may be challenging to prevent the condition. There are some things you can do to avoid the BV, and they include: 1. Avoid douching Douching happens to cause bacterial vaginosis, and stopping the habit can help prevent the vaginal condition. On the other hand, the routine can interrupt your vaginal bacterial health and cause bacterial vaginosis to recur. 2. Use of contraceptives If you want to be on the safe side, start using a condom when having sex with new partners and every time you have sex. Individuals that use condoms have a lower risk of contracting bacterial vaginosis. 3. Prolonged use of antibiotics When you use antibiotics for a long time, your problems are cured completely, and they may not return often. But the long-term usage of antibiotics can have other side effects on your vaginal environment and your body. 4. Impress birth control Women using hormonal birth control plans have a lower risk of contracting bacterial vaginosis. Use hormonal birth control such as rings, patches, injections, and pills to stay safe from BV. Nobody has proven this, but it is worth a try.
