This is perfectly natural, even if it “stinks.” When the sweat from your glands meets the bacteria on your skin, it breaks down into products called thioalcohols. The thioalcohols give off a strong, often sulfurous scent that can also be comparable to onions or meat.
Foods such as garlic, onions, cumin, and curry can also cause changes in body odor. The sulfur-like compounds that the body releases as it breaks down these foods can react with the sweat on the skin, producing body odor that may be different than a person's natural scent.
It turns out that when this sulfur compound is mixed with bacteria under the arm, it creates a chemical called thiol — and this chemical is known for smelling like onions. Men on the other hand, had increased levels of an odorless fatty acid, which gives off a cheesy smell once it mixes with the armpit bacteria.
Bromhidrosis is a disease that occurs when the bacteria on your skin breaks down sweat and produces an abnormally offensive smell similar to onions or sulfur. Bromhidrosis body odor is more pungent and persistent than ordinary B.O. There are two types of bromhidrosis: apocrine and eccrine.
A person living with a health condition such as diabetes or kidney disease may also have sweat that smells like ammonia.
In women, hormone levels change throughout the menstrual cycle, throughout pregnancy, during postpartum, or as a result of using medication with hormonal side effects. All of these changes can contribute to the intensity and pleasantness of body odor and there may be a link between our scent and attraction (5).
Two classic culprits for sweat induced stink are garlic & onions. Roasted garlic is delicious, but can be awfully strong. As a good source of potassium, folates, vitamins and minerals, you really don't want to lose alliums from your diet.
Garlic, onions,egg, and cruciferous vegetables — such as broccoli and cauliflower — can cause odour,” Dr Anupam Dey, a Kolkata-based dietician says. So, if you are eating high levels of certain foods, foul-smelling compounds they contain may be excreted through your sweat glands to give an unpleasant odour.
By the end of the study, researchers concluded that men who removed their armpit hair by waxing it off or shaving it with a razor had the least body odor. Those who simply trimmed their armpit hair had the next smelliest, with the strongest armpit odors coming from those who left their pit hair untamed.
Description. Trimethylaminuria is a disorder in which the body is unable to break down trimethylamine, a chemical compound that has a pungent odor. Trimethylamine has been described as smelling like rotten or decaying fish.
So, if you've recently increased the amount of odor-causing foods you consume, you may notice a difference in your body odor. This includes cabbage, broccoli, cauliflower, red meat, alcohol, caffeine, and monosodium glutamate (MSG).
The menopausal drop in estrogen also leaves our bodies with relatively higher levels of testosterone — produced by our ovaries in small amounts — than before. This can attract more bacteria to sweat, making it smell funkier.
Individuals with certain medical conditions are more susceptible to having body odour. These can include diabetes, urinary tract infections, an overactive thyroid, kidney and liver dysfunction and a genetic disorder called trimethylaminuria.
Bacteria love sweets, so eating too much sugar can cause an overgrowth of yeast on your skin, which in turn converts those sugars into alcohols that cause you to smell anything but sweet, according to Edward Group, a certified clinical nutritionist.
Diabetes and acetone-like breath
If the body cannot get its energy from glucose, it starts burning fat for fuel instead. The process of breaking down fat for energy releases byproducts called ketones. Acetone is a type of ketone, and it is the same fruity-smelling substance found in some nail polish removers.
Some metabolic diseases can cause a distinctive body odor, particularly in their later stages. These include diabetes, as well as advanced kidney and liver disease.
Internal health issues may result in unpleasant body odors (BO), as well, such as liver and kidney disease and hyperthyroidism, which can lead to excessive sweat and increased BO. Stagg recommends talking with your doctor if you notice a strong smell from your skin.
A person with kidney failure may have breath that smells like ammonia or urine. Serious liver disease can make breath smell musty or like garlic and rotten eggs. Compounds that are transported through the blood can also be released through your sweat glands. That can make your armpits and skin smell bad.
