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.
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.
Toothpaste and mouthwash can eliminate the sulfuric chemical compounds in onions that leave a lingering smell. Rub your hands together with toothpaste and mouthwash under running water for around thirty seconds.
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.
Trichomoniasis
Trichomoniasis is a sexually transmitted infection (STI) that can cause an unpleasant-smelling discharge.
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.
Using an over-the-counter (OTC) antiperspirant or deodorant (or a combination antiperspirant-deodorant) after your daily shower can help remedy armpit odor.
Baking Soda
You can take a small amount of baking soda and mix a little bit of water to form a semi-solid paste. Apply this paste to your armpits and allow it to dry. After it dries, wash it off. This might prove to be a good remedy for smelly armpits.
Some people with inflammatory bowel disease (IBD), including Crohn's disease and ulcerative colitis (UC), experience changes in body odor as a result of the disease. Although they are common symptoms, these odors can make a person feel anxious, affect their self-esteem, and even make them wary of leaving the house.
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.
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.
Changes to body odor may be due to puberty, excessive sweating, or poor hygiene. Sudden changes are typically caused by the environment, medications, or foods that you eat. However, body odor, especially sudden and persistent changes to your normal odor, can sometimes be a sign of an underlying condition.
Stress, certain medications, and alcohol use can also cause you to sweat more than usual. If you're still looking for a cause, look at your diet. Certain foods can change the way you smell. Cruciferous vegetables such as broccoli, cabbage, and cauliflower produce gas.
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.
One of the by-products of their metabolism is a group of sulphur-containing chemicals called thioalcohols. The exact thioalcohols produced will depend on your unique menagerie of skin bacteria, but some thioalcohols do indeed smell strongly of onion.
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.
Shiseido experiment finds humans produce 'stress smell' similar to onions. Japanese cosmetics maker Shiseido Co. has found that human bodies produce a distinctive odor that is similar to that of an onion or a long onion when they come under stress.
Foods like coffee, onion, meat, citrus, or garlic can trigger parosmia attacks, per the February 2022 paper. Parosmia often develops shortly after anosmia—the total or partial loss of smell—and/or hyposmia—which is the reduction in detecting odors—and it's been shown to develop after COVID-19.
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.
Bromhidrosis is foul-smelling body odor related to your sweat. Perspiration itself actually has no odor. It's only when sweat encounters bacteria on the skin that a smell can emerge. Other than body odor (BO), bromhidrosis is also known by other clinical terms, including osmidrosis and bromidrosis.
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.
Hormone imbalances and body odor often go together. Dips in estrogen can trigger hot flashes and night sweats, meaning you simply sweat more, which in turn can result in more odor. This is also a time of life filled with high levels of anxiety or stress, which can make you sweat, too.
