Are you worried about sweaty and stinky underarms? Sweaty underarms are common if you are living in humid places or doing rigorous workouts . But when accompanied with foul odour, they tend to bother you.
But, you don’t need to worry. Smelly underarms can easily be treated with a few quick hacks. Besides, you can take preventive measures to control the foul odour.
Scroll down to know what causes smelly underarms and how you can prevent them.
What Causes Smelly Underarms?
Most of the time, we associate underarm smell with sweat. But in reality, sweat itself is an odorless fluid. However, when bacteria on your skin breaks it down, it produces a foul odour. Essentially, there are two types of sweat glands. These are known as eccrine glands and apocrine glands. 
The eccrine glands are present all over your body and releases sweat that evaporates quickly from your skin’s surface. On the other hand, the apocrine glands are present in your armpit and groin areas that have more hair follicles. These glands enter your hair follicles and then release the sweat out of the body. When sweat is secreted from these glands, it blends with the bacteria on your follicles and produces a foul smell.
Other causes for smelly armpits are:
1. Proper Hygiene
Not maintaining proper hygiene can be one of the primary causes of smelly armpits.
The hair follicles present in your underarm can trap sweat. When the bacteria mixes with your sweat, it creates a foul odor. If you are not shaving your underarms often, chances of developing foul smell are there.
The apocrine sweat glands produce sweat, mainly under stress. Sweat is usually odorless, but it starts to produce smell when it comes in contact with your skin bacteria. Also, the apocrine gland is not active until one reaches puberty. Which is why you can notice body odor or smelly armpit once you hit puberty.
4. Food Habits
If you notice a sudden change of odour in your armpits, there might be reasons behind it. In such an instance, be mindful of your diet intake. Know that foods that contain high amounts of sulfur tend to alter the odour. These kinds of sulfurous food contain compounds that can't be broken down by your body completely. Hence the metabolic processes of your body produce volatile compounds which then leave your body by giving it an unpleasant odour.
When you consume excessive alcohol, the liver is not able to process it properly. It travels through your blood and around the body and seeps out through the pores and breath. It leads to foul smell.
Are Smelly Underarms A Sign Of Illness?
Smelly armpits are normal and the reason is most likely non-serious. But if you notice changes in your body odour suddenly, then there could be an underlying medical condition.
If you have diabetes and poorly controlled blood sugar levels, your body develops a condition called ketoacidosis that causes bad breath and foul body odour. If you’re suddenly noticing a bad breath like a rotten fruit bowl, speak to your doctor right away.
2. Overactive Thyroid Gland
An overactive thyroid can result in producing excessive sweat, thus causing your body to develop smell. This happens due to hyperfunction of your thyroid gland. If you sweat profusely, check with your doctor immediately.
3. Kidney And Liver Dysfunction
Kidney and liver are the two vital organs that help your body eliminate toxins. Dysfunction of either of the organs can lead to a strong, foul body odor.
How To Get Rid Of Underarm Smell?
1. Apple Cider Vinegar
Mix one cup of apple cider vinegar with one and a half cup of water. Mix well in a clean spray bottle. Spray the mixture on your underarms before you hit your bed and leave it overnight. Rinse it off with lukewarm water in the morning.
2. Aloe Vera Gel

Dried rosemary has a fantastic effect on neutralizing your body odor. Grind it to make a powder and apply it on your underarms.

10. Lavender Oil

How To Prevent Underarm Smell?
A research study has suggested in the past that shaving or waxing the underarm can keep your underarm smell in check. Here are some more tips that can help you reduce underarm odour.
1. Use an antiperspirant deodorant. Antiperspirant deodorants help to minimize perspiration while taking care of the skin.
2. Keep your underarms clean at all times. You may want to shave your underarms since the hair traps sweat. Removing your underarm hair can prevent underarm smell.
3. Choose to wear comfortable clothes that allow your underarms and skin to breathe. Natural fiber clothes like cotton, wool, silk, and linen allow the sweat to evaporate faster.
4. Avoid eating too spicy foods or those food items that are likely to trigger sweat.
5. Personal hygiene matters a lot. Make sure to take a daily shower.
6. Keep yourself adequately hydrated.
Why Do Your Underarms Still Smell After A Shower?
Hair is prone to trap sweat. When sweat reacts with bacteria on your skin, it leads to a foul smell. This is why people who have more body hair are prone to smell even after they take a shower. For the same reason, men have a lingering body odor as compared to women.
When to See A Doctor?
Underarm smell is not uncommon and shouldn't be a cause of concern. But if you notice that the smell has changed suddenly despite no alterations in your lifestyle habits, routine or diet, consult your doctor immediately. It might be a sign of an underlying medical condition, like a hormonal change. If you’re sweating profusely recently, that too indicates a medical condition like a hyperactive thyroid gland. In such cases, you need to see your doctor for medical intervention.
Underarm smell is a common concern for many of us. But the best part is it can be prevented by practicing proper hygiene and healthy habits. You can even go for simple yet effective home remedies to manage your body odour. Make sure you religiously follow a healthy diet, wear loose clothes, and avoid stress that can result in excessive sweating. However, if you notice sudden changes in your body odour, make sure to visit your doctor to seek medical advice.
