If the change in odor is due to infection, the smell may also be accompanied by:. Your environment, the things you eat, medications you take, shifts in hormone levels, or underlying disorders may all be behind a sudden change in body odor.
Changes in body odor can be a normal part of development, such as when an adolescent is going through puberty. During puberty, sweat glands and hormones become more active, which can cause BO. The foods you eat can sometimes cause a sudden, temporary change in body odor. For instance, many people experience a sudden, strong smell from their urine after eating asparagus. Certain foods can also cause you to produce more gas, which may lead to belching or flatulence.
Depending on the foods you eat, and how much gas you produce, this could create a foul smell. Some foods that may cause smelly gas include:. Your overall diet can also affect body odor. Some research has found that males who had a healthy diet high in fruits and vegetables had better-smelling sweat, no matter how much they sweat. On the other hand, self-reports showed that high carb intake was associated with less pleasant smelling sweat.
Other research suggested that high meat consumption may have a negative effect on body odor, compared to a plant-based diet. Bad breath can easily occur due to consuming certain foods, especially strong flavors such as spices, garlic, onions, or radish. Smoking tobacco products can also cause bad breath. Stress and anxiety can occasionally cause you to sweat more, leading to a stronger body odor.
If you have hyperhidrosis disorder , you sweat excessively and uncontrollably, sometimes for no apparent reason. Some people develop this disorder due to genetics, an underlying health condition, or while taking certain medications. According to research , hyperhidrosis and stress are connected. Many people who develop this condition experience stress, especially if the excess sweating affects their self-esteem or confidence.
Hyperhidrosis is often diagnosed in people with mental health conditions, such as social anxiety , which may influence its onset. It leads to high blood sugar. If blood sugar levels get very high, a complication called diabetic ketoacidosis DKA can occur. Ketones build up to dangerous levels in the body and are secreted into the blood and urine.
Additionally, DKA causes your breath to have a fruity odor. Original article can be viewed here. Despite the attempts of deodorant ads everywhere to convince us otherwise, people do not naturally smell like lilies and meadows. We all sweat, and we all smell to varying degrees in response to our perspiration. Ain't nothing wrong or weird about it. But unusual body odor from sweat can be a sign of various underlying bodily conditions , choices, and life stages — not just an indicator that you need to go and take a shower.
Some of them are actually quite serious, too, so that stink that's bothering your roommate could be a cause for genuine concern. Here's the basic way body odor works: in many cases, it's not actually something stinky being exuded from the pores in sweat form. That's because one type of sweat that our bodies produce is rich in fat.
Bacteria that is naturally found on our skin breaks down this fat-rich sweat and produces the range of smells we associate with body odor. In other cases, it's the result of certain substances emerging from the pores and causing a stink on their own terms, but that tends to be associated with either diet or certain medical conditions.
No, it's not a punishment from any deity for not doing the dishes that one time, and it doesn't come from nowhere. But it can indicate certain things if you know how to read it properly. Here are seven things that your body odor could be trying to tell you. Though to diagnose it, you may have to get up close and personal with some of your sweaty clothes, or at least ask your GP to do it for you.
Get prepared to get stinky. The Mayo Clinic has a good explanation for why stress does actually make us sweat in a specific way that can increase body odor. Other smells can be traced to problems with metabolism. With Diabetes, a lack of insulin causes the body to use fat instead of glucose for energy, resulting in fat metabolites like acetone showing up in the breath and sweat.
Trimethylaminurea is another example. A rare genetic disorder, Trimethylaminurea occurs when the body is unable to process trimethylamine, a breakdown product of choline, a common dietary component. Instead of being converted to trimethylamine oxide, which has no odour and passes through the urine, it is eliminated by passage through the skin where it produces a disturbing rotten fish odour. Most compounds that are found in the sweat of healthy people are not volatile enough to produce a scent until they are broken down into simpler molecules by the roughly one thousand varieties of bacteria that inhabit our skin.
The composition of this bacterial flora is determined both by genetics and environmental exposure. Body malodours and their topical treatment agents. International Journal of Cosmetic Science.
