Everyone wants to smell clean and fresh, but sometimes body odor can sneak up on them. Have you ever turned around and sniffed and smelled onions? The unpleasant odor is undesirable, but it is also not uncommon. Many people struggle with body odor.
There are many possible causes of a sudden change in your sense of smell. It can be anything from your environment to the food you eat. A health condition may even be at the root of your body odor emanating from your armpits, genital area, and feet.
Fortunately, you don't have to live with smelly armpits. We'll go over why your armpits smell like onions and what you can do about it.
What causes body odor?
The body odor you smell is a combination of sweat and bacteria from your skin. Everyone has bacteria on their skin that breaks down when it comes in contact with sweat. When this happens, the smell can be sour, sweet, sour, or like onions.
Your sweat doesn't actually have an odor, so it doesn't matter how much you sweat. Some people may sweat profusely but don't smell like B.O. Sweat is produced by two types of sweat glands in your body: eccrine and apocrine.
Your eccrine glands are responsible for the sweat you see on the surface of your skin. They cover most of your body and help regulate your body temperature. When you start to overheat, the glands produce eccrine sweat to cool you down. As sweat evaporates from the skin, it has a cooling effect that can bring body temperature back down. It's like a built-in air conditioner.
you also havedruses apocrinasopening into hair follicles. They are located on the scalp, armpits and groin area. They are usually larger glands that produce more sweat than eccrine glands.
These glands do not produce sweat until puberty. The smell of sweat from these glands comes from contact with bacteria that live on the skin.

If you're not going through puberty, there are other reasons you might experience a sudden change in body odor.
A change in diet can lead to a change in body odor. For example, asparagus can change the smell of urine. Foods like onions, cumin, garlic, and broccoli can also cause body odor. Once your body metabolizes the food, the odor will go away.
One study found that men whohealthy nutritionof fruits and vegetables had better body odor. People who ate more carbohydrates reported a less pleasant smell.
You may sweat more when you have high levels of stress and anxiety. Stress can cause many problems by releasing more hormones. The main stress hormones are cortisol and adrenaline, which can increase sweating. The extra sweat combined with bacteria already on your skin creates body odor.
Diabetes is a disease that occurs when the human body does not produce enough insulin or cannot use it properly. It leads to problems like high blood sugar levels. Elevated blood sugar levels can lead to diabetic ketoacidosis, which can alter body odor. In this case, you should immediately consult a doctor.
