If you have diabetes, a change in body odor could be a sign of diabetes-related ketoacidosis. High ketone levels cause your blood to become acidic and your body odor to be fruity. In the case of liver or kidney disease, your odor may give off a bleach-like smell due to toxin buildup in your body.
Some people with diabetes compare the smell of insulin to the scent of Band-Aids, printer ink, Lysol, or new plastic shower curtain liners (4). Apparently, phenols are responsible for the aroma associated with insulin (5).

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.
Apocrine bromhidrosis is the most common form of bromhidrosis in adults and is localised, usually to the armpits and/or anogenital area. Eccrine bromhidrosis presents as a generalised malodour, and may be associated with bad breath (halitosis), anogenital odour, and smelly urine.
But your apocrine glands, usually only found in your armpit area, are activated when you're under psychological stress, explains Preti. This sweat produces a strong, sometimes even sulfurous odor when you're anxious or scared.
Trimethylaminuria symptoms can be present from birth, but they may not start until later in life, often around puberty. The only symptom is an unpleasant smell, typically of rotting fish – although it can be described as smelling like other things – that can affect the: breath. sweat.
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.
Causes of body odour

Occasionally, an overactive thyroid can also cause body odor. This is because the patient tends to sweat excessively due to the hyper-functioning thyroid gland. This condition can also be ruled out by physical examination and blood studies.
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).
A person's diet can make their sweat smell like ammonia. A person who eats a diet high in protein but low in carbohydrates may produce ammonia that the body then releases in sweat.
Here's the spoiler: Yes, people in online keto diet forums occasionally complain about an unpleasant change in body odor when they first go keto. There is no scientific evidence that it actually happens, nor a clear, compelling explanation for why it would.

If you have diabetes insipidus, you'll continue to pee large amounts of watery (dilute), light-colored urine when normally you'd only pee a small amount of concentrated, dark yellow urine.
Body odor is caused by bacteria breaking down the sweat from the apocrine glands in your armpits, groin, and pubic area. You may be more prone to body odor if you are overweight, eat certain foods, have certain health conditions, or are under stress. Genetics may also play a role.
Skin conditions
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.

Humans are able to smell sickness in someone whose immune system is highly active within just a few hours of exposure to a toxin, according to research published in Psychological Science.
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.
Do people with trimethylaminuria smell themselves? Yes, just like typical body odor or sweat, people with TMAU may notice how they smell. But like typical body odor or sweat, some people with TMAU may be accustomed to the smell and less likely to react to it than those around them.
Bacteria generally cause sour-smelling sweat. Everyone has bacteria on their skin, and when the bacteria start to break down the sweat, it creates an odor. If you run hot at night, causing sweating, try reducing your room temperature or wearing cooler clothing.
