Body odour (BO) is a common issue that can be caused by a variety of factors, including diet, hygiene, and bacterial activity on the skin. While BO can be unpleasant, it is typically not a cause for concern and can be managed through improved hygiene practices. However, in some cases, persistent and offensive body odour may be a symptom of a medical condition called bromhidrosis, which is characterised by an abnormally strong and unpleasant smell that does not improve with regular hygiene practices. This condition can be treated or prevented through improved hygiene, but there are also medical treatments available. Interestingly, research has shown that men's sweat tends to smell like cheese, while women's sweat smells like onions.

The bacteria Staphylococcus epidermis can cause a cheesy body odour
Body odour is caused by a combination of bacteria and sweat on the skin. While sweat itself is odourless, it can produce a smell when it comes into contact with the bacteria on the skin. The odour can vary from person to person, ranging from sweet to sour to tangy or onion-like.
The bacteria Staphylococcus epidermis, which is present on the skin, can cause a cheesy body odour. This occurs when the bacteria degrade leucine, an amino acid present in sweat, into isovaleric acid, a compound that smells like cheese. Staphylococcus epidermis is a fast-growing bacteria and is the dominant staphylococcal species present on the skin, especially in the axilla or armpit region.
While Staphylococcus epidermis does not metabolise certain odour precursors, such as thioalcohols, it can produce other odour-causing compounds. For example, it can produce diacetyl, a key contributor to unpleasant odours, through the metabolism of organic acids in sweat. Additionally, Staphylococcus epidermis is associated with the production of branched-chain fatty acids, which can also contribute to body odour.
The presence of Staphylococcus epidermis and other odour-causing bacteria can be influenced by various factors, including genetics, age, sex, and diet. Additionally, certain medications, supplements, or foods can further contribute to body odour by affecting the smell of sweat. While body odour can be masked with deodorants and antiperspirants, it is important to note that, in some cases, it can be an indication of an underlying health condition.

Body odour is caused by microbes on the skin metabolising compounds in sweat
Body odour, or BO, is caused by microbes on the skin metabolising compounds in sweat. While sweat itself does not smell, when it comes into contact with bacteria on the skin, it can create a strong, persistent odour. This is because the bacteria break down the compounds in the sweat, producing malodorous byproducts.
Apocrine sweat, which is released by apocrine glands, is thicker and contains more proteins and lipids than eccrine sweat. Eccrine sweat is mostly water and salt and is released by eccrine glands, which are found all over the body. Unlike apocrine sweat, eccrine sweat does not naturally have a strong smell. However, both types of sweat can lead to abnormal body odour when they come into contact with bacteria.
The type of bacteria on the skin and how it interacts with sweat determines the body odour. The most common bacteria that produce body odour include members of the Corynebacterium, Staphylococcus, and Cutibacterium genera. The odour can be attributed to the production of volatile organic compounds (VOCs), including volatile fatty acids and thioalcohols, which have an unpleasant odour.
The odour of body odour can vary depending on factors such as diet, hygiene, and the specific bacteria present on the skin. For example, a diet that includes certain foods such as garlic can contribute to an onion-like or garlicky odour. The odour can also be influenced by medications, hormones, and underlying conditions.
In some cases, body odour may be a symptom of an underlying medical condition. If the odour persists despite good hygiene practices and over-the-counter treatments, it is recommended to consult a doctor to rule out any potential health issues.

Male armpits tend to give off a cheese-like smell due to higher fatty acid production
Body odor is caused by a combination of bacteria and sweat on the skin. While sweat itself does not have a smell, when it comes into contact with the bacteria on the skin, it can produce an odor. This odor can vary from person to person and can be influenced by factors such as diet, hygiene, and the specific bacteria present on the skin. Male armpits tend to give off a cheese-like smell due to the production of higher quantities of fatty acids.
The apocrine sweat glands, which develop during puberty in hairy regions like the armpits, secrete an oily fluid composed of proteins, lipids, and steroids. When bacteria on the skin break down these compounds, it can result in the production of volatile organic compounds (VOCs), including volatile fatty acids and thioalcohols, which contribute to body odor.
One of the key fatty acids responsible for the cheese-like odor is isovaleric acid, also known as 3-methyl butanoic acid. This compound is produced by the Staphylococcus epidermis bacteria and is also found in several types of strong cheese. Additionally, members of the Corynebacterium genus, particularly Corynebacterium jeikeium, are more commonly found in the armpits of men and produce other medium- and short-chain fatty acids that contribute to the cheese-like smell.
It is important to note that body odor can also be influenced by factors such as hormones, medications, and underlying medical conditions. For example, changes in hormone levels during menopause can lead to excessive sweating and alterations in body odor. Additionally, certain medications and supplements can affect the way sweat smells. In some cases, body odor may be an indication of an underlying disease or infection, and it is recommended to seek medical advice if the odor persists or is accompanied by other symptoms.

Body odour can be an indicator of an underlying disease, such as diabetes or kidney disease
Body odour is produced when the bacteria on the skin meet sweat. On its own, sweat doesn't have a smell, but when bacteria on the skin break down protein-rich sweat, it can create a strong, persistent odour.
In the case of kidney disease, an ammonia smell on the breath or body can be an indicator. This is caused by the buildup of urea in the body due to the kidneys' inability to effectively filter waste products from the blood. When urea reacts with saliva, it forms ammonia, resulting in an ammonia odour.
It is important to note that while body odour can provide insights into potential health issues, it should not be considered a standalone diagnostic tool. If you notice persistent or unusual body odour, it is recommended to consult a medical professional to rule out any underlying health issues.

Body odour can be influenced by diet, hygiene, and the bacteria present on the skin
Body odour is primarily produced by the breakdown of sweat, sebum, and keratin by bacteria on the skin surface. When bacteria on the body start to break down dried sweat, it can result in an offensive smell. This odour can be influenced by diet, hygiene, and the bacteria present on the skin.
Diet can play a significant role in body odour. The consumption of certain foods, such as garlic, onion, asparagus, alcohol, or specific medications, can affect the way our sweat smells. For example, the sulphur compounds in onion and garlic can mix with bacteria under the arms, resulting in a chemical called thiol, which is known for its onion-like odour. Similarly, increased levels of an odourless fatty acid, which is present in men, can give off a cheesy smell when it comes into contact with armpit bacteria.
Hygiene is another critical factor in body odour. Poor hygiene can lead to an excessive build-up of bacteria on the skin, resulting in a stronger odour. Maintaining good hygiene habits, such as regular washing with soap and water, can help neutralise the bacteria and reduce body odour. This is especially important in areas with high concentrations of sweat glands, such as the armpits and feet, where body odour tends to be more concentrated.
Additionally, the type of bacteria present on the skin can influence body odour. Different individuals have varying bacterial compositions, which can result in distinct odours. For example, men and women have different bacterial make-up, which contributes to the difference in the smell of their sweat. Furthermore, the bacteria responsible for body odour can be influenced by factors such as genetics, climate, and underlying health conditions.

Frequently asked questions
The smell of body odour (BO) is caused by the breakdown of sweat proteins by bacteria. When bacteria on the skin break down sweat, it can create a strong, persistent odour. This odour can vary depending on factors like diet, hygiene, and the bacteria present on the skin.
Bromhidrosis is a medical condition characterised by abnormally offensive body odour. It is caused by the interaction between sweat and skin bacteria, particularly when sweat contains high levels of lipids and proteins. The smell of bromhidrosis can be cheesy or sour, like the smell of aged cheese or fermented foods.
Bromhidrosis can often be treated or prevented through changes to your hygiene habits, such as washing at least daily with soap and water. There are also medical treatments available, such as surgery to remove the sweat glands themselves.
According to a study by Swiss scientists, men's sweat contains increased levels of an odourless fatty acid. This gives off a cheesy smell once it mixes with the armpit bacteria.
