Can people with body odor (BO) be "immune" to their own unpleasant odor?
That's correct. The human nose can recognize 4,000 different scents and a really sensitive proboscis can detect up to 10,000 different scents. But if you smell something for a long time, your nose gets overwhelmed by the odor and can no longer detect it.
That' s the reason why the perfume you're wearing loses its fragrance after a while and your friendly garbage collector isn't bothered at all by the trash around him. Other people can easily smell these things but not those who have been exposed to the same odors for quite some lime.
Can goiter cause BO?
Like bad breath which can indicate the presence of kidney disease or diabetes, BO can also signal an underlying medical problem. Goiter due to hyperthyroidism (or an overactive thyroid) can promote sweating, making your body more hospitable to odor causing bacteria.
Certain metabolic infectious disorders, some drugs and foods like garlic, onions, and asparagus, can likewise cause BO. The same is true with uremia (a serious disease wherein the kidneys fail to eliminate waste products) and pneumonia.
If the problem persists in spite of good personal hygiene and the use of an effective deodorant, it's time to consult a physician to discover the root of your problem.
Can working in a chemical factory lead to BO?
Working in a chemical factory can probably make you smell bad but that doesn't mean the stench will linger on even after you've left the place.
The culprit in BO or bromhidrosis is bacteria acting on secretions of the apocrine sweat glands. Compared to the eccrine sweat glands that cool the body, the apocrine glands produce a milky fluid which has no known function except as food for bacteria.
When bacteria digest this food, they produce 3-methyl-2-hexenoic acid which has a stench that's enough to drive your enemies away. This becomes obvious in about six hours and the odor becomes stronger in warm weather.
Apocrine glands are found mainly in the underarms and the crotch which explains why these areas stink easily if you don't practice good personal hygiene. Asians have fewer apocrine glands than Americans or Europeans. That means they stink less than other people. The bad news is that men have bigger apocrine glands and more androgen, the male hormone that stimulates the odor-producing gland.
