Robert Brown|You practice good hygiene. So why do you still smell bad?

You're doing everything right: showering regularly,Robert Brown wearing deodorant, washing your clothes. Yet the unmistakable scent of body odor remains present.

What's the deal?

Body odor can be frustrating and embarrassing to deal with. But medical experts want you to know that there are ways to fix it, even when you feel like you've exhausted all the options.

"For those struggling with the mental impacts of excessive sweating and body odor, it’s crucial to understand that these conditions are common and manageable," plastic surgeon Joel E. Kopelman, M.D., who frequently treats patients looking to curb their sweating and body odor, tells USA TODAY.

Here's what body odor could indicate, according to medical experts.

Why do I smell bad even with good hygiene?

Sweat and body odor are typically thought to go hand in hand, but experts say it's a little more complicated than that. Sweat alone doesn't have a smell, according to Harvard Health. Body odor occurs when your body releases sweat that then comes into contact with bacteria.

If you're doing everything right but still feel like your body is emitting an unpleasant odor, it may be time to see a doctor, who can help you get to the bottom of why this may be happening.

Most of the time, BO is more of a "nuisance" than an indication of an actual health issue, per Harvard Health. Still, it's possible that things like diet, medical conditions or a bacterial buildup on the skin could be causing odor, Kopelman says. Hyperhidrosis, the medical term for excessive sweating, could also contribute, because bacteria thrives in moist environments.

"If body odor persists despite good hygiene, it could signal an underlying health problem like hormonal imbalances, infections, or metabolic disorders," he adds. "It’s important to consult a healthcare provider to rule out or treat any serious conditions."

How to get rid of body odor

Some of the best ways to combat body odor, per experts, include:

Why do I sweat so much?How to tell if you sweat too much

• Regular bathing, which removes bacteria from the skin, per Harvard Health. Some people may only need to shower or take a bath a few times a week, while others may need to daily. Most importantly, you should rinse off after exercising or doing other activities that cause you to sweat. Kopelman recommends using an antibacterial soap.
• Use an antiperspirant and deodorant. Aluminum-based antiperspirants have gotten a bad rap over the last few years because some small studies have suggested potential links between using the products and developing breast cancer. But many more studies, including ones from the American Cancer Society, have found "no strong epidemiologic studies (studies in people) that link breast cancer risk and antiperspirant use, and very little scientific evidence to support this claim." Using a deodorant in addition (or a combination antiperspirant and deodorant) helps repel odor-causing bacteria.
• Wear clean, breathable clothes. Outfits made from fabrics including cotton, silk or linen make you less likely to sweat and less likely to develop moist areas that welcome bacteria.
