Yes, severe liver damage can cause a distinctive, sweet, musty, or garlic/rotten egg smell on the breath, called Fetor Hepaticus, due to the buildup of toxins like dimethyl sulfide that the failing liver can't filter out. This serious symptom indicates advanced liver disease and requires immediate medical attention, as it can also manifest in urine or sweat and is linked to other signs like confusion, jaundice, and swelling.
Foetor hepaticus is a feature of severe liver disease; a sweet and musty smell both on the breath and in urine.

Yet, metabolization of odorants does not only occur in the OE. Especially the liver is known as the major hub for the biotransformation of xenobiotics in humans (for further information on general metabolism within the human body see e.g. Rodrigues and Rowland, (2020) ).
How do you check your liver health?
Too Much Alcohol
Alcoholic fatty liver, which causes liver inflammation (alcoholic hepatitis), eventual scarring (cirrhosis) and even liver cancer, is a process that begins on as little as four drinks a day for men and two for women. By the time you show symptoms, your liver may be damaged beyond repair.

Excessive Alcohol Consumption
When alcohol is consumed, the liver works overtime to metabolize it. Over time, excessive alcohol consumption can lead to inflammation, scarring, and even cirrhosis of the liver. This chronic damage significantly increases the risk of liver cancer.
It exhibits a typical egg-white-like, marine-like odor at low concentrations, and an intense orange-citrus, animal-like odor at higher concentrations.
Foul-smelling urine may be due to bacteria. Sweet-smelling urine may be a sign of uncontrolled diabetes or a rare disease of metabolism. Liver disease and certain metabolic disorders may cause musty-smelling urine.
The first signs of a bad liver often include persistent fatigue, nausea, loss of appetite, unexplained weight loss, and a dull ache or tenderness in the upper right abdomen. Other subtle indicators can be general malaise, feeling unwell, or mild digestive issues like bloating or fatty stools, which might be overlooked but signal the liver isn't processing nutrients properly.
The fastest way to repair your liver involves immediate lifestyle changes: stop alcohol/smoking, adopt a healthy diet (whole foods, less sugar/fat/processed items), manage weight/exercise, and avoid liver-harming medications, all while consulting a doctor for personalized guidance, as severe damage needs medical intervention for reversal.
Pruritus is one of the most common symptoms experienced by patients with cholestatic liver disease. Pruritus associated with cholestasis is characteristically localized to the palms and soles, although generalized itching can also occur.
Fetor hepaticus means “fetid liver” or “liver stench”. It's a type of chronic bad breath that's actually a symptom of liver disease. It has a distinctive smell — some say, like rotten eggs and garlic. It's a serious symptom.
Vitamin E. Vitamin E is an antioxidant, which means it's a nutrient that may help protect cells against damage. Research suggests that in people who have MASLD, vitamin E may boost the liver's natural antioxidants, help reduce liver inflammation and scarring, and help prevent fat buildup.
Symptoms of acute liver failure may include:
Rarely, people can have bad breath because of organ failure. 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.

Nonenal® (also known as 2-Nonenal) is a naturally occurring compound responsible for the distinct odor associated with aging. It typically appears after age 40, becoming more noticeable in both men and women.
Alcohol is perhaps the most well-known cause of liver damage. When you drink, your liver works to break down the alcohol and clear it from your system. But too much alcohol overwhelms this process, causing toxic by products to build up and damage liver cells. Alcohol-related liver disease progresses in stages.
When symptoms do occur, they may first include fatigue; weakness and weight loss; nausea; bruising or bleeding easily; swelling in your legs, feet or ankles; itchy skin; redness on the palms of your hands; and spider-like blood vessels on your skin.
To cleanse your liver, focus on a healthy lifestyle by eating antioxidant-rich foods (berries, leafy greens, cruciferous veggies, citrus), staying hydrated with water and green tea, getting regular exercise, maintaining a healthy weight, and drastically reducing or eliminating alcohol, processed foods, and sugar, as your liver naturally detoxifies itself with proper support.

Symptoms of non-alcoholic fatty liver disease
Some people have symptoms including: feeling very tired. feeling generally unwell. liver pain or discomfort, which is felt in your tummy (abdomen) under the right side of your ribs.
As the liver becomes more severely damaged, more obvious and serious symptoms can develop, such as: yellowing of the skin or whites of the eyes (jaundice) swelling in the legs, ankles and feet caused by a build-up of fluid (oedema)
