When the bacteria break down the sweat they form products called thioalcohols, which have scents comparable to sulfur, onions or meat. "They're very very pungent," says Bawdon.
The best way to prevent smelly armpits is to wash daily and after sweating. Using antiperspirant or deodorant and shaving the armpits can also help. Avoiding alcohol and certain foods, such as onions and garlic, will also help prevent smelly armpits in some cases.
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.
Eating food with a strong smell can affect body odor. Onions, garlic, spices, and vinegar are among the foods that can change the smell of sweat. Sweat can combine with vaginal discharge to make the vagina smell of strong foods, such as onions or garlic.
A dry mouth allows bacteria to thrive. Bacteria that live in the mouth can make compounds that have sulfur. These compounds are especially stinky. They can smell like rotten eggs or onion, for example.
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.
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.
ODOR AFTER A SHOWER IS DUE TO LINGERING BACTERIA
In addition to bacteria, oftentimes there is deodorant residue and other impurities that are trapped in the underarm pores and within the hair if you have armpit hair.
Apocrine sweat glands are located in the armpits or genital area. When you have apocrine bromhidrosis, body odor is the byproduct of lipid-rich apocrine gland sweat mixing with skin bacteria. When these two ingredients come together, they produce thioalcohols — compounds that smell like sulfur, onions or raw meat.
If you're concerned about sweating and body odor, the solution may be simple: an antiperspirant or deodorant. Antiperspirant. Antiperspirants contain aluminium-based compounds that temporarily block sweat pores, thereby reducing the amount of sweat that reaches your skin.
Infrequent showering can cause bacteria to build up on your skin. Shower at least once a day (or every morning and night) and scrub your extra-sweaty areas with a scent-free, antibacterial bath soap. Stay away from strongly scented soaps, which can make your armpits smell worse.
Less body odor
When you remove hair under the armpits, it reduces trapped odor. A 2016 study involving men found that removing armpit hair by shaving significantly reduced axillary odor for the following 24 hours. Similar results were first found in a 1953 paper .
Things like stress, hormonal changes, new medications, and different lifestyle factors (like harder workouts or shifts in the weather) can all impact how you sweat, and your go-to deodorant may not be able to stand up to the new situation.
“The liver and kidneys really take care of detoxing the body from any harmful chemicals. There's no way to get them out of the sweat glands or out of the skin.” There's no evidence that toxins can be physically pulled out of the skin or deeper layers of tissue.
Lemon juice
This wonder ingredient that's readily available in every kitchen helps lower the pH level of your skin, thus killing bacteria that produce body odour. Cut a lemon in half and rub your underarms with the halves, squeezing them a bit as you go. Let it air-dry to prevent underarm odour.
Certain health conditions.
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.
If your breath smells like acetone -- the same fruity scent as nail polish remover -- it may be a sign of high levels of ketones (acids your liver makes) in your blood. It's a problem mainly of type 1 diabetes but also can happen with type 2 if you get a serious condition called diabetic ketoacidosis (DKA).
Shower daily and wash your underarms with an antibacterial soap (consider showering twice a day if you sweat excessively) While in the shower fill your hand with hydrogen peroxide and splash and rub it into each of your underarms.
Sour underarms are caused by sweat in contact with bacteria on the skin. This condition often occurs in people with hyperhidrosis, mainly in the areas of the hands, feet, and armpits. There are two main types of sweat glands, eccrine and apocrine.
A person living with a health condition such as diabetes or kidney disease may also have sweat that smells like ammonia. A person can try antiperspirants to reduce the amount they sweat, and deodorants to cover up any odors. A doctor can treat any underlying health conditions to help reduce the ammonia smell in sweat.
When your body temperature rises, these glands release fluids that cool your body as they evaporate. Apocrine glands are found in areas where you have hair, such as your armpits and groin. These glands release a milky fluid when you're stressed. This fluid is odorless until it combines with bacteria on your skin.
