A vomit-like smell is usually caused by butyric acid or volatile organic compounds (VOCs). Common culprits include:
This odor has been associated with various chemicals (such as butyric acid or carboxylic acid, plastic and vinyl products and even flowers and food products). One frequent cause of this odor is the use of old dirty water containing cleaning solutions on floors, walls and other surfaces which in drying emit this odor.
Vomit smells overwhelmingly sour and pungent primarily due to butyric acid and stomach acids breaking down food. If you notice a vomit-like smell in your environment or on your body, the specific culprits are often surprising.
Yes, body odor and changes in your natural scent are widely reported by Mounjaro users, though it is not a medically listed side effect. This happens because the medication alters your metabolism, hormones, and digestion.
Key Takeaways. A vomit-like smell coming from the skin can be a symptom of hidradenitis suppurativa (HS), a chronic skin condition that causes painful bumps and abscesses.
Chronic gastrointestinal conditions.
Some chronic diseases of the gastrointestinal tract, such as Crohn's or celiac disease, can cause bad breath from the stomach. They can slow or limit digestion, leaving food that can be broken down into strong-smelling sulfur compounds by intestinal bacteria.
Smelling vomit (or a similarly foul odor) when no such substance is present is generally caused by phantosmia (an olfactory hallucination) or parosmia (a distorted sense of smell).
The distinct scent often referred to as "old person smell" is caused by a chemical compound called 2-nonenal. It is not a result of poor hygiene, but rather a completely natural biological byproduct that occurs as human skin matures and ages.
"Ozempic legs" is a non-medical, pop-culture term used to describe the changes in the appearance of the legs—specifically the thighs—following rapid weight loss from GLP-1 medications like Ozempic or Wegovy.
Ketoacidosis causes breath to smell distinctly sweet, fruity, or like acetone (the exact chemical scent of nail polish remover). Some people describe the odor as being similar to overripe fruit, pear drops, or even Juicy Fruit gum.
The chemical that gives vomit its distinctively sharp, foul smell is butyric acid (also called butanoic acid) [0.5.1,0.5.5]. It is a short-chain fatty acid produced by the breakdown of fats and anaerobic fermentation. Humans are highly sensitive to it, capable of detecting it at extremely low concentrations of just 10 parts per million.
Low estrogen, common during perimenopause and menopause, typically causes body odor to become more intense, musky, or sour due to shifts in sweat composition and vaginal pH. Vaginal scent may change to become more alkaline, sometimes described as slightly sweet, bready, or yeasty. Other common smells include a sharper, stronger, or onion-like scent underarms or in the groin.
It's generally found in dairy products, and is a product of anaerobic fermentation. Hence the links to butter and parmesan cheese. And.. as well known, butyric acid is what gives vomit that distinctive, smell-it-a-mile-off, odor. And this is why we're so good at detecting it.
Organ failure causes distinctive smells because the body can no longer filter toxins, resulting in a buildup of chemical compounds that are exhaled through the breath or released through the skin. The specific scent depends entirely on which organ is failing.
The smell of vomit can linger due to a combination of gastric acids, enzymes, food, and bacteria, making it stubborn to remove from carpet. Generally, the smell can last for a few hours with proper cleaning. Using an enzyme or Oxy-based cleaner can speed up the deodorization process to remove any vomit odors.
Vomit associated with liver failure is typically bright red or dark brown/black (resembling coffee grounds) due to bleeding in the upper gastrointestinal tract. It can also appear yellow or green, which indicates the presence of bile—a digestive fluid produced by the liver.
Foetor hepaticus is a feature of severe liver disease; a sweet and musty smell both on the breath and in urine. It is caused by the excretion of dimethyl disulphide and methyl mercaptan (CH3SH)2, arising from an excess of methionine.
High blood sugar (hyperglycemia) occurs when your body doesn't produce enough insulin or can't use it effectively. Five common warning signs include:
Uncontrolled diabetes most commonly causes a sweet, fruity, or solvent-like scent—similar to nail polish remover (acetone) or overripe fruit. This is caused by a buildup of chemicals called ketones, which are produced when the body burns fat instead of glucose for energy.
It refers to the loss of volume and shape of the buttocks, as well as the loss of skin elasticity that can occur with rapid weight loss, especially when it is accompanied by significant weight loss. "Ozempic butt refers to the changes that you see in volume, shape and skin of your buttocks after weight loss," said Dr.
Amy Schumer stopped taking Ozempic (and subsequently Wegovy) because it caused severe gastrointestinal side effects, particularly unbearable nausea and vomiting. The medication made her so sick and weak that she was often bedridden, making it impossible for her to engage in everyday activities or play with her son.
«Ozempic mouth» is a non-medical, colloquial term used to describe a cluster of oral and facial changes experienced by some users of GLP-1 weight-loss medications (like Ozempic, Wegovy, or Mounjaro). It primarily refers to dry mouth, accelerated tooth decay, and facial aging around the mouth.
"Old person smell"—scientifically known as 2-nonenal—is caused by fatty acids oxidizing on the skin. Because it is not water-soluble, standard body washes and intense scrubbing won't wash it off. To eliminate it, you need to use soaps containing Japanese persimmon extract and green tea.
"Old person smell" can begin as early as age 40, as the body produces more of the compound 2-nonenal. This, often described as a grassy, greasy, or musty odor, is a natural part of aging caused by the breakdown of unsaturated fatty acids and declining skin antioxidant defenses. While it starts around 40, it becomes more noticeable in the 50s and beyond.
