We're going to assume you bathe, at least somewhat regularly.


And yet, somehow, you still find yourself wondering... IS THAT ME?!





Turns out, there are the occasional smells that no amount of scrubbing or brushing or deodorant-applying can deter. Here are a few of the most surprising.




You're Stressed

Believe it or not, there are different types of sweat, chemically speaking. And the stinkiest sweat of all is stress sweat. That's because it's produced from a category of sweat glands called apocrine glands. Aprocrine glands produce a less-watery sweat, and bacteria go crazy for the fats and proteins in the mix. That feeding frenzy is what releases the odor[1] , according to the Mayo Clinic. Sweat from your workouts or just because it's too dang hot outside, on the other hand, is composed mostly of water and electrolytes[2] , according to YouBeauty.




You've Been "Blessed" With Stinky Feet

That same all-you-can-eat buffet for bacteria happens with the sweat on your feet. And since your tootsies are tucked away in a dark, warm, moist environment, they really nurture bacteria -- especially if you're sans socks. But about 10 to 15 percent of people have extra-sweaty feet just by the luck of the genetic draw. Those ultra-moist dogs can then become home to a specific type of bacterium called Micrococcus sedentarius, which produces truly awful smelling sulfur compounds[3] . Lucky you.




You Have Too Few Favorite Bras

Ladies: 'fess up. How often do you wash your favorite bra? Yep, we thought so. "Many women overwear -- and consequently underwash -- bras because they have too few that fit properly," bra expert (really!) Susan Nethero told Prevention. Because that lacy number is probably made of odor-trapping fabrics[4] and definitely touches skin in more than one sweat-prone place, you probably need to wash it more often than you think, and neglecting to do so could cause odor.




You Love Broccoli

You've probably heard that eating a diet heavy in garlic and onion can stink up more than just your mouth. It's true -- smelly foods are broken down into smelly compounds that circulate in the blood stream and come out through the breath, sweat and urine[5] , WebMD reported.


But garlic and onion aren't the only offenders. In fact, broccoli, Brussels sprouts and other veggies in the cruciferous family include those same smelly compounds -- typically, sulfur -- and can lead to all-over stench.




You Have A Rare Genetic Disorder Called Trimethylaminuria

Mutations in a specific gene have been discovered to create a condition called trimethylaminuria[6] , which causes the body to be unable to break down a chemical compound called trimethylamine. Trimethylamine[7] is what gives fish its fishy smell, and when it builds up in the body it's released in the breath, urine and sweat, giving a person with trimethylaminuria a similarly fishy smell, according to the Genetics Home Reference at the National Institutes of Health. The odor can be extremely disruptive to daily life, often resulting in depression and social isolation, according to the NIH.




You've Been Drinking

While you can't exactly sweat off that hangover, you do sweat out some booze when you drink. As alcohol courses through your blood and around your body, some seeps out through the pores[8] -- and, quite evidently, through the breath. It doesn't matter what type of alcohol you drink; once the body begins to break it down it all smells the same[9] .




You Could Have Diabetes

When diabetes is untreated, it's possible to experience what's called diabetic ketoacidosis[10] . Without enough insulin, the body starts to break down fat for fuel, which leads to a build up of ketones in the body. That buildup in turn may produce a change in body odor, according to the Mayo Clinic, and may be a sign it's time to see a doctor.


Some people also report a similar change in body odor when switching to a diet heavy in meat and low in carbs. A low-carb diet is known to impact the smell of breath[11] .

  • Medications


    It's not that your Rx is causing a stink, but meds carry with them dry mouth as a side effect. Saliva is essential to washing odor-producing particles free, so when there's less of it, odor increases. It's essentially <a href="http://www.mayoclinic.com/health/bad-breath/DS00025/DSECTION=causes" target="_blank">the same reason you get morning breath</a>, according to the Mayo Clinic.




  • Respiratory Tract Infections


    A bout of bronchitis or even a cold might be the cause of that stench. According to a 2006 report, respiratory tract infections cause bad breath thanks to <a href="http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1570844/" target="_blank">"nasal or sinus secretions" passing into the throat and mouth</a>. Bronchitis, pneumonia, sinus infections and postnasal drip <a href="http://www.webmd.com/oral-health/guide/bad-breath" target="_blank">can all lead to bad breath</a>, WebMD reports.




  • Mouth Breathing


    So you're a mouth breather. Aside from your propensity to drool while you're sleeping, you might find yourself with stinkier than average breath upon waking. That's because, just like with certain medications, <a href="http://www.huffingtonpost.com/thomas-p-connelly-dds/bad-breath_b_1415851.html" target="_blank">breathing through the mouth cuts down on saliva</a>, leading to a drier, smellier mouth.




  • Obesity


    A 2007 study found that obese people were more likely to have bad breath, but a 2013 study took that link a step further. It turns out that organisms that live in the gut of obese people may give off a certain, distinctive gas, causing <a href="http://healthland.time.com/2013/03/27/can-you-smell-obesity/" target="_blank">bad breath in the mouths of the overweight</a>. The specific microbe in question is present in about 70 percent of people, but higher in about 30 percent, possibly predisposing those folks to obesity, Time.com reported.




  • Skimping On Carbs


    Atkins Diet fans will recognize the word "ketosis". This fat-burning process occurs when the body turns to fats and proteins for energy, since carbs aren't available, Kenneth Burrell, DDS, told WebMD. In this state, however, <a href="http://www.webmd.com/oral-health/features/low-carb-diets-can-cause-bad-breath" target="_blank">the body releases certain chemicals into the breath that cause odor</a> -- and this isn't a stink you can brush away, he said. "All the brushing, flossing and scraping of the tongue that you can do is not possibly enough to overcome this." Everything in moderation, even carbs.




  • Underlying Medical Conditions


    It might not be the typical "bad" breath you're used to; rather <a href="http://health.usnews.com/health-news/articles/2008/12/02/8-surprising-causes-of-bad-breath" target="_blank">a "potent" fishy smell could signal kidney problems</a>, and whiffs of fruit could be a sign of uncontrolled diabetes, US News reported. <a href="http://www.mayoclinic.com/health/bad-breath/DS00025/DSECTION=causes" target="_blank">Certain cancers produce chemicals</a> in the body that may in turn lead to "distinctive breath odor," according to the Mayo Clinic, and chronic heartburn may also contribute to bad breath, since stomach acid is constantly refluxing.
