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.
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.
Changes in body odour could also mean you might be sick or have an underlying condition. Conditions like diabetes, kidney disease, liver disease can make body odour worse. If you have diabetes and your blood sugar levels get too high, your breath may start to smell fruity.
Thyroid problems.
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.
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.
Parosmia is a distorted sense of smell. It happens when smell receptor cells in your nose don't detect odors or transmit them to your brain. Causes include bacterial or viral infections, head trauma, neurological conditions and COVID-19. Parosmia is usually temporary, but in some cases, it's permanent.
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.
“Viruses themselves do not produce odours. When the virus has infected our cells, this can have a knock-on effect on various systems within the body, which results in odours being released through our skin and breath. So there was a really strong likelihood that coronavirus would produce a distinct odour as well.”
Severely ill patients often have characteristic smells. Patients with diabetic ketoacidosis have the fruity smell of ketones, although a substantial number of people are unable to detect this. Foetor hepaticus is a feature of severe liver disease; a sweet and musty smell both on the breath and in urine.
Most of the time body odor isn't a problem and a shower will quickly wash it away. But if you notice a change in body odor or you're sweating much more than usual, it could be a sign of a medical condition that needs treatment.
Compounds that are transported through the blood can also be released through your sweat glands. That can make your armpits and skin smell bad.
In the recovery phase of COVID-19, a patient normally regains their senses back. However, some people experience a change to their sense of smell about three to four months following infection. People report certain things—like food or body odor—smelling like garbage, rotten eggs, or chemicals.
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.
The culprit is an enzyme called C-T lyase, found in the bacterium Staphylococcus hominis, which dwells in human armpits. These bacteria feed on odorless chemicals released in sweat, which the enzyme then converts into thioalcohols—a pungent compound responsible for the offending smell.
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.
One such sign of high blood sugar is peculiar body odours, especially in your breath. It is crucial to be aware of these signs and seek immediate medical treatment.
Hair is another place where bacteria like to hide. If you still smell a strong body odor after a shower, consider shaving the hair in your armpits, groin, and chest. The hair's surface is a perfect place for bacteria to call home, and it's harder to eliminate them from the hair than your bare skin.
Dear Reader: Many of us who have slogged through the unpleasant symptoms of a cold or the flu know that losing your sense of smell, and often a large portion of your sense of taste, is a common part of the experience. The same has proven to be true with COVID-19.
Parosmia is a condition where a person's sense of smell no longer works correctly. Caused by infections like COVID-19, head injuries, or other neurological conditions, this loss of smell can be an inconvenience for some— and a significant problem for the quality of life of others.
Trimethylaminuria (TMAU) is an uncommon condition that causes an unpleasant, fishy smell. It's also called "fish odour syndrome". Sometimes it's caused by faulty genes that a person inherits from their parents, but this isn't always the case. There's currently no cure, but there are things that can help.
Examples include amphetamines, adrenaline, pseudoephedrine, certain antidepressants (fluoxetine, paroxetine, venlafaxine), tricyclic antidepressants (desipramine, nortriptyline), opioids (tramadol, codeine), pregabalin, gabapentin, pilocarpine, omeprazole, thyroid medications, and nonsteroidal anti-inflammatory drugs.
