Extreme body odor (bromhidrosis) is primarily caused by bacteria on the skin breaking down sweat from apocrine glands (rich in fats/proteins) in areas like armpits and groin, but can also stem from diet (garlic, spices, alcohol), medications, stress, genetics, certain infections, or underlying medical conditions like diabetes, kidney/liver disease, or hyperhidrosis (excessive sweating).
This could be due to diet (like eating spicy foods, garlic, or onions), stress sweat that mixes with bacteria, hormonal changes during puberty or menopause, or even medical conditions like diabetes or hyperhidrosis.
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.
Bacterial overgrowth
Your underarms are a playground for bacteria. Even after a thorough wash, some bacteria can stick around and cause odor. They thrive in warm, moist environments, making your underarms their favorite hangout spot.
Without enough B12, your metabolism can slow down, leading to more odor-causing byproducts being released through your sweat. Plus, B12 helps maintain healthy skin, which acts as a barrier to bacteria that cause bad smells. You can find B12 in foods like meat, eggs, and dairy, or through supplements.
Bacteria on your skin cause body odor. It's completely normal to have a natural body odor and isn't necessarily related to how much you sweat. Sweat itself is odorless. Some medical conditions, genetics, having overweight or eating certain foods could make you more susceptible to bad body odor.
Body odour during menopause is caused by the decline in oestrogen; this ends up leaving our bodies with more testosterone which is produced in small amounts by the ovaries. This hormonal shift can make your sweat more appealing to bacteria, which in turn leads to body odour.
Sweating and body odor of the underarms often can be treated with antiperspirants or deodorants that you can buy without a prescription: Antiperspirants. Antiperspirants contain metal salt, such as aluminum, that blocks sweat pores. This reduces the amount of sweat that reaches the skin.
Diabetes: Diabetes is one of the most well-known health conditions linked to changes in body odor. People with uncontrolled diabetes can experience a fruity or acetone-like smell (think nail polish remover) on their breath or skin.
Kids start to have body odor around the time puberty starts and hormones change. Usually, this happens when females are 8–13 years old, and males are 9–14. But it can also be normal to start puberty earlier or later. Bathing every day, especially after a lot of sweating or in hot weather, can help with body odor.
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.
Trimethylaminuria (TMAU) is a rare disorder in which the body is not able to metabolize the chemical trimethylamine, and this causes body odor.
Conditions like kidney disease, diabetes or hyperhidrosis can affect how your body processes waste, leading to an intense ammonia smell. It's essential to tune into your body's signals and consult with a healthcare professional if you suspect your sweat's scent is more than just a dietary or exercise-related quirk.
The methods outlined make use of basic and widely available ingredients, that you probably already have at home.
Hyperhidrosis: Hyperhidrosis causes excessive sweating from the eccrine glands. If someone sweats a lot, sweat may buildup on the skin and interact with bacteria. This may cause an odor, which may smell of ammonia.
Periodontal disease, also known as gum disease, can cause chronic bad breath (halitosis) and an unpleasant taste in the mouth. The smell is often described as foul, rotten, or putrid, similar to decay or a sulfur-like odor.
Ten early signs of diabetes include increased thirst/urination, extreme hunger, fatigue, blurred vision, slow-healing sores, tingling in hands/feet, frequent infections (skin, gum, vaginal), unexplained weight loss (often Type 1), dry mouth/skin, and dark skin patches (acanthosis nigricans), with symptoms varying by type, emphasizing the need for regular checkups.
Causes of body odour
hormonal changes. being overweight. having a condition like diabetes, kidney disease or liver disease. certain types of medicine, such as antidepressants.
The number one sign of diabetes is dark, velvety skin on the neck, armpit, or groin. If you have diabetes, your dermatologist can be your partner in skin care.
Bacteria Buildup
If showering doesn't get rid of your underarm odor, you might be dealing with stubborn bacteria. We all have a mix of “good” and “bad” bacteria living on the surface of our skin, including the skin in our armpits.
How to Detox Your Armpits
Some of these activities include:
Missing B6 or B12 vitamins can affect your body's ability to process and eliminate odor-causing byproducts. These vitamins are involved in metabolism and the breakdown of amino acids. A deficiency can lead to the production of more odor-causing compounds, impacting your body's natural scent.
Here are 10 of the warning symptoms to look out for:
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.
