Body odor in teens is not uncommon and maybe a common complaint after puberty. While teenagers may have issues with self-confidence and self-esteem due to body odor, it may help to know that it is normal and does not always indicate an underlying pathology (1). The condition is more common in teenage boys than girls. Sweating is often the main reason for body odor, but there may be other reasons. Read the post to learn about the causes, management, and signs you need to see a doctor for body odor.

Possible Causes Of Body Odor In Teens

Excessive sweating (hyperhidrosis) is the primary reason for body odor in teens. This is due to overactive sweat glands. Besides that, some of the common reasons for teenage body odor could be:

  1. Hormonal changes: During and after puberty, hormones rise and cause increased secretion by the sweat and oil glands. The sweat produced is odorless. But bacteria on the skin surface decompose the sweat into ammonia and fatty acids that emit a peculiar or pungent odor (2).
  1. Poor hygiene: Not bathing or changing clothes regularly can cause excess bacteria to accumulate on the skin, especially in the underarms, groins, and on the feet. It increases the possibility of developing body odor (3).

  1. Food choices: Consumption of certain foods such as strongly-flavored spices, garlic, milk-based products, fish, soya beans, and plants from Brassicaceae or Alliaceae families may cause distinct body odors (4). However, this is not just specific to teens but for children and adults too.
  1. Bromhidrosis: It occurs when the skin bacteria interact with sweat and break it down into malodorous compounds, thus causing body odor (5). This condition usually occurs in the palms, soles, and skin folds.
  1. Trimethylaminuria: It is also called fish odor syndrome, and may occur in teenagers and adults. The condition occurs when the body is unable to process trimethylamine, a compound naturally produced within the body. Accumulation of trimethylamine in the body causes a fish-like odor to develop in the person’s urine, breath, and sweat (6).
  1. Premature adrenarche: It is when the adrenal glands attain maturity earlier than normal. It can cause the teen to develop body odor (7). 
  1. Superadded infections: Scabies is common in the underarms or groins. This causes intense itching and a body odor. There maybe superadded bacterial infections, which teens tend to hide. The underarms should be carefully examined.

  1. Phenylketonurea: It is a condition whereby the body does not process phenylalanine and excretes it in the urine or sweat. This is a mousy smell. The child should be on a protein restricted diet i.e not eat meat or consume protein.

How To Get Rid Of Teenage Body Odor?

Take a healthy diet and be well hydrated. In addition to that, here are some tips you may follow to prevent and control body odor in teens:

  1. Shower with antibacterial soap: Regular bathing with antibacterial soap and washing parts like armpits, groin, and feet could remove sweat and body odor-causing bacteria.

  1. Wear clean clothes: Wearing clean cotton clothes (including inners, t-shirts, socks) could help in reducing body odor as they are breathable and absorb sweat. Materials, such as rayon, silk, and polyester, are not breathable and may cause more perspiration.
  1. Deodorants: Deodorants may cover or block the body odor, while antiperspirants dry up or prevent sweating. Antiperspirants containing aluminum zirconium and aluminum chloride are considered effective (8).
  1. Cutting down certain foods: Limiting strong-flavored and strong-smelling foods such as garlic, fish, and spices may help reduce the body odor.

You may even try some home remedies for body odor in teens.

  1. Apple cider vinegar: Anecdotal evidence suggests that apple cider vinegar can adjust the pH level of the skin, thereby eliminating the odor. However, it should be diluted in water and applied using cotton on the armpits. For foot odor, soak the feet in warm water (with one part of apple cider vinegar) for about 15 minutes.

  1. Epsom salt: Soaking feet in Epsom salt may also help in reducing foot odor (9).
Quick tip
Wear cotton or moisture wicking socks under your shoes. However, the shoes may still absorb the odor. You can throw your shoes in the washer, or use baking soda, baby powder, or a deodorizing shoe spray or powder in your shoes (13).
  1. Wheatgrass juice: According to the International Journal of Chemical Studies, wheatgrass juice is known to have odor-reducing properties (10).
  1. Natural deodorants: Some natural alternatives to deodorants include lemon juice (can kill bacteria causing odor), coconut oil (antibacterial properties), and baking soda (neutralizing odor). These can be applied topically or mixed with some more ingredients to make a homemade deodorant (11).

When To See Doctor?

If the body odor seems strong and out of control, then it is good to seek a doctor’s opinion. Also, see a doctor if these home remedies do not provide any relief. If the teen sweats excessively and already has another medical condition, then it becomes essential to visit a doctor.

Frequently Asked Questions

1. Does puberty increase body odor?

The sweat and perspiration from sweat glands contribute to body odor. Due to the onset of puberty, these glands become more active and start secreting various chemicals into a sweat, which results in a stronger smelling body odor (12).

2. Does body odor in teens indicate illness?

Yes. Sometimes the body odor in teens can be a symptom of illnesses such as diabetes and liver or kidney disease. Excessive sweating in a teen could indicate hyperhidrosis. If you notice these changes, consult your child’s doctor immediately (13).

Body odor in teens usually arises from causes that are not benign. It may result from hormonal changes, hygiene issues, food choices, or some other treatable medical conditions. Body odor can be mainly managed by certain lifestyle changes such as changing clothes frequently, deodorants, bathing regularly, and cutting down on certain foods that may lead to foul body odor. Some home remedies can also help curb body odor. Excessive sweating and persistent foul odor can indicate a need for medical attention.
