Body odour is the unpleasant smell produced by bacteria on the skin that break down the acids in your sweat.
The medical term is Bromhidrosis.
Anyone who has reached puberty can produce body odour, as this is when the apocrine sweat glands develop, which produce the sweat that bacteria can quickly break down.
Men are more likely to have body odour, because they tend to sweat more than women.
Things that can make body odour worse include:
*consuming rich or spicy food and drink – such as garlic, spices and alcohol
*some types of medication – such as antidepressants
*certain medical conditions – a fruity smell can sometimes be a sign of diabetes, while a bleach-like smell may indicate liver or kidney disease
Hyperhidrosis is a condition where a person sweats excessively and much more than the body needs to regulate temperature.
If you have hyperhidrosis, you may also have smelly feet (bromodosis).
Smelly feet are caused by wearing shoes and socks that prevent sweat evaporating or being absorbed, which attracts bacteria.
When to see your GP:
See your GP if:
your sweating or body odour is causing you distress
you notice a change in your body odour
you suddenly begin to sweat much more than usual.
Managing body odour
Excessive sweating and body odour is an unpleasant problem that can affect a person’s confidence and self-esteem.
A body odour problem can usually be managed by getting rid of excess skin bacteria – which are responsible for the smell – and keeping the skin in the affected area (usually the armpits) clean and dry.
Your armpits contain a large number of apocrine glands, which are responsible for producing body odour.
Keeping your armpits clean and free of bacteria will help keep odour under control. Following the below advice can help you achieve this:
*take a warm bath or shower every day – to kill the bacteria on your skin; on hot days, you may need to have a bath or shower twice a day
*wash your armpits thoroughly – using an antibacterial soap
*use a deodorant or an antiperspirant – after bathing or showering
*regularly shave your armpits – this allows sweat to evaporate quicker, giving bacteria less time to break it down
*wear natural fibres, such as wool, silk or cotton – they allow your skin to breathe, which means your sweat will evaporate quicker
*wear clean clothes – make sure you wash your clothes regularly
*limit the amount of spicy foods you eat – such as curry or garlic, because they can make your sweat smell; evidence also suggests that eating a lot of red meat tends to make body odour worse.
Deodorant and antiperspirant:
The active ingredients used in antiperspirants and deodorants differ, so you may find some more effective than others.
Deodorants work by using perfume to mask the smell of sweat. Antiperspirants contain aluminium chloride (see below), which reduces the amount of sweat produced by your body.
Use roll-on antiperspirants if you sweat heavily, as they tend to be more effective.
Aluminium chloride is the active ingredient in most antiperspirants. It helps prevent the production of sweat.
If the above self-care advice doesn’t improve your body odour, you may need a stronger antiperspirant that contains more aluminium chloride.
Your GP or pharmacist can recommend a suitable product and advise about how often you should use it.
Aluminium chloride solutions are usually applied every night before bed, and washed off in the morning. This is because you stop sweating in your sleep, so the solution can seep into your sweat glands and block them. This reduces how much you sweat the next day.
As the aluminium chloride solution begins to take effect, you can use it less often (every other night, or once or twice a week).
