Body Odor: Causes, Symptoms And Treatment

Introduction

Everybody has a unique body odor, which may be subtle or pleasant, but most people think body odor means an unpleasant smell. Changes in body odor occur due to excessive sweating, puberty, or poor hygiene. Sudden changes are typically caused by the medications, environment, or foods that we eat. But sudden and persistent changes in body odor can sometimes be a sign of an underlying condition.

What Is Body Odor (Bromhidrosis)?

Body odor happens when sweat mixes with bacteria on the skin. Sweat itself is odorless, but when it comes into contact with bacteria, especially in areas like the armpits and groin, it can produce smells that are sweet, sour, tangy, or like onions. Body odor is not always related to how much a person perspires. An individual can smell strongly despite sweating little, while another may sweat profusely without smelling much. This is because the odor is largely brought about by the type of bacteria on the skin and their interaction with sweat.

There are two types of sweat glands in the body:

• Eccrine: Eccrine glands are found all over the body and help cool the skin by releasing odorless sweat.

• Apocrine Bromhidrosis: Apocrine glands, located in areas like the armpits and groin, release a thicker type of sweat that can smell when mixed with bacteria.

These glands become active during puberty, which is why young children usually do not have body odor. While sweating is a natural process, factors like diet, hygiene, and genetics can influence how sweat smells. If there’s a sudden change in the amount of sweat or the way it smells, it might signal an underlying medical condition.

Who Gets Body Odor (Bromhidrosis)?

Bromhidrosis can happen to anyone, no matter their age, race, or gender. But it is more common in adults since the sweat and oil glands responsible for body odor usually start working after puberty. As people get older, their body odor also changes, which makes it different from that of babies, children, teenagers, or younger adults. Men are more likely to be affected than women, and the condition tends to be worse in hot and humid climates. Genetics might also play a part; research shows that strong underarm odor is more often found in people of European and African origin than in those of Asian descent.

What Are the Causes of Excessive Body Odor (Bromhidrosis)?

Environment, diet, medications, changes in hormone levels, or underlying conditions may cause a sudden change in body odor. It is normal to have a change in body odor when we are growing, such as an adolescent going through puberty. At the time of puberty, sweat glands and hormones are more active, causing body odor.

During the workout, excessive sweat causes body odor. Odor from sweat decomposition occurs when bacteria on the skin break down sweat, producing an unpleasant smell. In such cases, when healthy hygiene habits are not practiced properly, the sweat can mix with bacteria and cause an unpleasant smell. But when the body odor is persistent and accompanied by other symptoms, it may occur due to any other underlying condition. Odor from sweat decomposition occurs when bacteria on the skin break down sweat, producing an unpleasant smell.

• Diet: Food can sometimes cause a sudden change in body odor. Many people experience a sudden, pungent smell from the urine after eating asparagus, and once the food is metabolized, the smell goes away. Certain foods produce more gas, leading to belching or flatulence. The amount of gas produced will depend on the food we eat. Foods that cause smelly gas are bok choy, broccoli, cabbage, asparagus, and cauliflower. The overall diet can affect body odor, and certain foods with powerful flavors, such as garlic, spices, onions, or radish, can cause body odor. Smoking tobacco can also cause bad breath.

• Hyperhidrosis: Stress can occasionally cause one to sweat more. Hyperhidrosis disorder causes excessive and uncontrollable sweating with no apparent reason. This disorder can occur due to genetics, certain medications, or an underlying health condition. Also, it is diagnosed in people with mental health conditions.

• Diabetes (Diabetic Ketoacidosis): When the body does not produce enough insulin or cannot effectively use it, diabetes mellitus occurs, leading to high blood sugar. A very high blood sugar leads to a complication called diabetic ketoacidosis (DKA), where ketones start to build in the body and are secreted into the blood and urine. Also, it causes the breath to have a fruity odor.

• Infections: Vaginal infections, such as bacterial vaginosis or vaginal parasite infection, may cause a sudden change in odor. Infections that occur outside the vagina may also cause a change in body odor. Trichomoniasis, a parasitic sexually transmitted infection, may change the vaginal odor. Skin infection may cause a sudden smell at the site of the infection. Skin infections that might cause a smell are erythrasma (bacterial skin infection), trichomycosis axillaris (bacterial infection of the underarm), and intertrigo (yeast infection).

• Athlete's Foot: When your feet suddenly start to smell bad and itch, a common fungal infection called athlete's foot has developed. This is because fungus thrives in the moist, warm environment of the shoes and socks. When healthy foot hygiene habits are not practiced, you may develop them.

• Cancer: Unpleasant body odors have been reported in people with advanced cancer, but the body odors occur due to infected cancer-related wounds.

What Are the Signs and Symptoms of Body Odor (Bromhidrosis)?

Body odor symptoms usually occur in specific areas of the body. Some common areas are armpits, genitals, feet, belly button, mouth, and throat. A change in smell from the stool, earwax, urine, or genital discharge can be noticed. The odor can vary despite the location. It can be foul-smelling, spicy, sour, fishy, bitter, or even sweet. The other symptoms will depend on the cause, and when the change in odor is due to an infection, the smell may be accompanied by a rash, redness, itching, discharge, oozing, or discoloration.

How Is Body Odor (Bromhidrosis) Diagnosed?

Body odor, also known as bromhidrosis, is usually diagnosed by a doctor through a simple check-up. They will look at the affected areas and may smell the odor to understand its strength. The doctor will ask when the odor started, how strong it is, and if anything makes it better or worse. They might also ask about hygiene habits, diet, and any health issues. Most of the time, no tests are needed. But if the smell is very strong or unusual, the doctor may look for other causes, like skin infections or medical conditions. In some cases, they may take a skin or sweat sample to rule out infection. Overall, the diagnosis is mostly done by observing symptoms and asking a few questions.

What Is the Treatment for Body Odor (Bromhidrosis)?

1. Dietary Modifications: When body odor occurs due to foods, avoid them, and include variety in the diet.

2. Treating Hyperhidrosis: When hyperhidrosis occurs secondary to an underlying condition, treating it will help alleviate the symptoms. A doctor consultation is needed when it occurs due to certain medications. When it occurs due to an unknown cause, there are prescription creams or antiperspirants, bromhidrosis surgery, medications, and Botox injections to treat it. Surgical treatment for bromhidrosis may be considered when other options fail to control severe body odor. Consulting a mental health professional and practicing some relaxation techniques may also help.

3. Diabetes Management: When there are symptoms of diabetic ketoacidosis, a fruity-smelling breath can be experienced. In such cases, emergency medical treatment should be given. Diabetes mellitus can be managed by adequately managing blood glucose levels with medications, natural remedies, or alternative treatments for bromhidrosis.

4. Treating Infections: Many types of infections are not serious, but they should be handled properly to avoid complications. Infections are treated depending on the cause, and the treatments are usually done with an antifungal or with a bromhidrosis treatment antibiotic agent. Usually, topical medications are given, but oral or intravenous medications may be given as well.

5. Treatment of Athlete's Foot: Athlete's foot can be treated with home treatments, with talcum powder, over-the-counter antifungal powders, ointments, sprays, and lotions, oils such as tea tree or neem, sea salt baths, and hydrogen peroxide or rubbing alcohol.

6. Managing Cancer: Having cancer will not usually smell, but an infected wound related to it can cause a sudden change in body odor. When there is a sudden change in body odor and has also been diagnosed with cancer, then speak with the doctor to treat the infected wound.

7. Supplements or Medications: In case of a vitamin deficiency, get more vitamins by adding certain foods to the diet or by taking supplements.
