To prevent bacterial vaginosis (BV), several effective strategies focus on maintaining healthy vaginal flora and reducing exposure to risk factors. Key preventive measures include:

• Maintain proper vaginal hygiene by rinsing with warm water only, avoiding douching, scented vaginal products, and harsh soaps or cleansers.
• Wear breathable, loose-fitting underwear made of natural fabrics like cotton, and change underwear or panty liners if they become damp.
• Use barrier contraception such as condoms during any type of sex to reduce bacterial imbalance caused by semen exposure.
• Limit the number of sexual partners and avoid having sex until BV is treated to reduce risk.
• Avoid practices that disturb the vaginal environment, like wiping from back to front, and avoid smoking or vaping.
• Consider probiotics containing Lactobacillus to help maintain a healthy vaginal bacterial balance.
• Avoid vaginal deodorants, powders, and strong detergents on underwear.

Following these guidelines can lower the risk of developing BV and prevent recurrence after treatment. If ongoing issues occur, consulting a healthcare provider for appropriate diagnosis and treatment is important.
