Body Odour in Kids: Causes, Prevention & Home Remedies

Body Odour in Children – Reasons, Remedies and Prevention

You may be in love with that sweet fragrance associated with babies as you hold them close to you. But then this notion goes out of the window as they grow older and come in closer contact with the environment. As they grow older, they become more active and always like to dig their face first into the trash. However, there is a huge difference between a kid getting stinky owing to their interaction with the environment and actually developing body odour. As a parent, if you find your child is developing an odour even with a good hygiene routine, then it could be a cause for concern.

Is Body Odour in Children Normal?

Body odour is caused when bacteria act on the sweat produced by the sweat glands in our body. The eccrine sweat glands present throughout the body release sweat when you have a fever, eat spicy food or in hot and humid condition. The apocrine glands, sensitive to adrenaline release, sweat when the body experiences physical activity, fear, anxiety or stress. The sweat created by these glands are generally oily and odourless but can create odour on interaction with bacteria.

Body odour emitted in children is hardly noticeable. Children aged under eight do not have an odour. However, prepubescent teens and teenagers may have a distinct odour. So if your 12 -year old sends a whiff of bad odour, it is simply a sign of the onset of puberty. If your girl sweats and smells like an adult at around eight and your boy at around nine, then there is no need to worry. But if your 3-8 year old is getting smelly, then it is a cause of alarm and must not go unnoticed.

Causes of Body Odour in Kids

Anything is easier to be dealt with if you are aware of the cause. Some common causes that cause body odour in kids:

1. Poor Hygiene

2. Food habits

Food that your child eats has a direct correlation to body odour. What goes in comes out in a distasteful manner. The food consumed not only affects their breath but their odour too. After some food are digested they seep into the pores of the skin and create an odour. Some common food that causes odour in kids and adults are:

  • Garlic and onions.
  • Red meat which has an amino acid called carnitine.
  • Milk and dairy products take a longer time to digest so excess consumption. releases methyl mercaptan and hydrogen sulphide causing a foul smell.
  • Smelly food like fish, eggs, legumes and other spicy food.
  • Processed food and foods that lack fibre.

3. Puberty

If your child is closer to the puberty attaining age, then body odour is quite normal. Girls reach puberty between 10 and 14 and boys between 12 and 15. During this phase, their body goes through a lot of hormonal changes leading to changes in their physical appearance and behaviour. Their sweat glands work overtime and it is normal for them to have body odour. Early sexual maturation in kids known as Adrenarche is another cause for body odour.

4. Fish Odour Syndrome (Trimethylaminuria)

A rare condition caused by the abnormal production of Flavin enzyme, trimethylaminuria is a metabolic disorder in children. It stops the chemical trimethyluria from breaking down to trimethylamine oxide. This results in the chemical getting accumulated and causes the urine, breath and sweat to smell like a fish.

5. Underlying Medical Condition

A very distinct body odour in your child signals an underlying medical condition like a kidney or liver-related ailment, diabetes or inflammation of organs. If your child is sweating profusely then they may have hyperhidrosis. It is necessary to seek medical intervention in such instances.
