Many women claim that douching makes them feel cleaner, eliminates embarrassing odor and protects them against infection. But they may be doing harm to themselves along the way.

I advise my patients not to douche on a regular basis. The vagina is a self-cleaning organ. When you try to cleanse it yourself by using a douche, you actually flush out the normal, healthy microbes as well as temporarily change the pH (acidic vs. basic nature of the vagina). Rather than providing protection, this sets up an environment that makes it easier for infections to develop.

Additionally, all douche formulations — save for the pure saline varieties — contain ingredients that could trigger an adverse or allergic reaction.

The term, douche, which means “to wash” or “to shower” in French, refers to cleansing the vagina using a solution of water mixed with another fluid — often vinegar, baking soda or some sort of perfume.

Women frequently tell me that they douche because they’re concerned about odor. I tell them it’s normal to have some odor. It’s also normal to have the odor change in nature and intensity throughout the menstrual cycle.

Some patients say they notice more odor after making a change in diet, such as eating garlic, tuna or beginning to take dietary supplements. Once they stop consuming the offending food or other products, the odor usually goes away.

Washing the outside area — the vulva — with deodorant soap can decrease the natural odor, but it may also dry out the sensitive tissue, so I advise women to use caution. Most physicians recommend washing only with water, especially if you’re experiencing dryness, itching or burning.

Some odors may occur due to a health issue. If you smell a persistent and foul odor, or if any odor is accompanied by a thick or greenish discharge, you may have an infection. See your OB/GYN for a firm diagnosis and treatment. Also, definitely visit your doctor if you have pain, rawness or sores in your vaginal area.
