Yeast infections, bacterial vaginosis and menopause all can change vaginal discharge. These conditions can make you uncomfortable, but there are treatments that can help.

Sometimes, differences in your discharge can be a symptom of something more serious. Some sexually transmitted infections (STIs) can cause changes to vaginal discharge. STIs can be a danger to your body's health and to others. So knowing if you have an STI is important.

Brownish or blood-tinged discharge can be a sign of cervical cancer. But this is rare.

Schedule a visit with your health care provider if you have:

• Greenish, yellowish, thick or cheesy vaginal discharge.
• Strong vaginal odor.
• Itching, burning or irritation of your vagina or of the area of skin that surrounds the vagina and urethra, also called the vulva. You might notice a change in color to these tissues. They may be a shade of red, purple or brown depending on your skin color.
• Bleeding or spotting outside of your period.

For self-care at home:

• If you think you have a yeast infection, try an over-the-counter antifungal cream (Monistat, M-Zole, Mycelex). But it's better to be sure before you self-treat. Often people think they have a yeast infection when they actually have something else. If you're not sure, it's important to seek care first.
• Wash the vulva with warm water only. Do not wash inside the vagina. Then, gently blot dry with a cotton towel. Don't use scented soaps, toilet paper, tampons or douches. These can make discomfort and discharge worse.
• Wear cotton underwear and loose clothing. Avoid tight-fitting pants or pantyhose without a cotton crotch.
• If your vagina is dry, try an over-the-counter cream or gel to add moisture.
• See your care provider if your symptoms don't go away. You might need to try a different kind of treatment.
