Why Do My Armpits Smell Like Onions?

Some people have a condition called bromidrosis, where the body produces abnormal amounts of sweat and the sweat has a strong odor.

It is often described as smelling like onions or garlic. This condition can be caused by emotional stress, medications, or certain medical conditions.

If you are concerned about your body odor, talk to your healthcare provider. They may be able to help you determine the cause.

How Can I Reduce Body Odor?

A healthy diet and lifestyle can help reduce body odor. These tips may help:

Drink at least eight glasses of water every day. Water is good for the skin, and it helps flush toxins from the body. Dehydration can cause bad breath and dry the skin around the mouth, nose, and groin area, causing a body odor problem.

Wear loose-fitting clothing made of natural fibers like cotton that breathe better than synthetic fabrics. Synthetic fabrics like polyester retain moisture against the skin, which causes odor as bacteria feed on sweat or sebum (oil produced by glands in the skin).

Avoid using scented soaps, perfumes, and deodorants if possible. Overuse of these products can cause sensitivity to perfumes and make you smell worse instead of better!

Instead, use mild unscented soap on your underarms and genitals to keep them clean without adding a scent that could cause an allergic reaction in people with sensitive skin or allergies to scented products.

If you use scented products, do not use them every time you shower or bathe because this will only increase sensitivity to perfumes over time.

Also, be aware that some people may be allergic to ingredients in many commercial deodorants/antiperspirants such as aluminum compounds, propylene glycol (derived from petroleum), parabens (preservatives), and triclosan (an antibacterial agent).

People with sensitive skin should try unscented deodorant/antiperspirants first before trying any other types of deodorant/antiperspirant products for any period and should stop using if irritation occurs or does not resolve after continued use for a few days.

How to Stop Armpits from Smelling Like Onions?

Many people have found that their armpits have a robust onion-like smell. However, you can do a few things to stop this from happening so frequently. The first thing you can do is avoid spicy foods, which will make your body sweat more heavily and make the smell worse.

It would help if you also tried to stay dry, as wet armpits can also be an issue. Finally, it would be best to try deodorant instead of antiperspirant because antiperspirants block sweating altogether, and deodorants only cover up the smell of sweat.

Clean Them

The best way to stop armpit odor is by getting rid of the bacteria responsible for the bad smell. The bacteria that causes this odor is called Staphylococcus aureus.

This type of bacteria lives on the skin, even in not sweaty or smelly people. You can kill off these bacteria with some simple steps.

First, you want to make sure you wash your armpits with soap and water. Next, you want to dry your armpits off with a towel or paper towel.

You can also use an anti-bacterial product on your armpits before drying them off. This will also help kill the bacteria that causes this foul odor.

Dry Them

If you have been working out or been in a hot environment, the sweat from your pits may cause a bad smell. To prevent this from happening, you should use an antiperspirant with aluminum chloride to stop the sweat from making your armpits smell.

You can also wear a shirt that covers your pits and armpits, which will allow for airflow.

Use a Deodorant

If you don’t want to use an antiperspirant due to health or personal preferences, you can use a deodorant. A deodorant will stop the smell of sweat by eliminating the bacteria that causes it. They also have other benefits, such as a moisturizing effect that keeps your skin soft and moisturized.

It can also prevent acne and other skin problems due to sweating. There are different deodorants on the market, such as spray, roll-on, and stick deodorants. Some people may prefer one type over another, but you should try different types until you find one that works best for you.

Use a Natural Deodorant

If you don’t like using conventional deodorants because they contain harmful chemicals, you may want to try an all-natural option instead. Natural deodorants are made with natural and organic ingredients that are safer than conventional deodorants.

These deodorants are also free of aluminum which is terrible for your health if used too much. Some natural ingredients include baking soda, coconut oil, lavender oil, aloe vera gel, and more, so you should check out different natural brands until you find one that works best for you.

You can find these products at any health store or online stores like Amazon or eBay, where they come in many different scents and varieties, so there is something for everyone!


Armpits are one of the most odoriferous body parts. Many people are not aware that the armpit’s sweating process is different from what happens elsewhere in the body. The armpit has a gland called an apocrine gland, which produces sweat that has a distinct smell.

The apocrine glands in the armpit secrete perspiration with pheromones and proteins that attract mates. This is why your axilla (armpit) smells more robust than other areas of your body.

If you suffer from excessive sweating or hyperhidrosis, then you know how embarrassing it can be to have sweaty armpits that smell bad.

Many antiperspirants are explicitly designed for people with excessive sweating, but these products may not be enough to remove the odor, especially if you have sensitive skin.

Botox injections can reduce underarm sweating by blocking nerve signals to the sweat glands in your armpits. Botox injections can provide permanent relief from excessive underarm sweating in most patients.

Still, there are risks involved with using this procedure for this purpose, so make sure to consult with your doctor before trying it out.

Final Thoughts

Body odor is something that everyone has to deal with. It’s not something that should be ignored because it can be a severe problem. There are many causes of body odor, but the most common one is that your sweat is not getting washed away.

The sweat can mix with bacteria on your skin and create an unpleasant smell. To get rid of body odor, figure out which one of the above-mentioned tips can help.
