The cause of body odor along with sweating stems from your body's temperature regulation system,
specifically your sweat glands. Our skin has two types of sweat glands. Eccrine glands occur over most of your
body and open directly onto the surface of the skin. Apocrine glands develop in areas abundant in hair
follicles, such as on your scalp, armpits and groin. When the body temperature rises, the autonomic nervous
system stimulates the eccrine glands to secrete fluid onto the surface of our skin, where it cools our body as
it evaporates. This fluid (perspiration) is composed mainly of water and salt (sodium chloride) and contains
trace amounts of other electrolytes.
Apocrine glands, on the other hand, secrete a fatty sweat directly into the tubule of the gland. When one is
under emotional stress, the wall of the tubule contracts and the sweat is pushed to the surface of the skin
where bacteria begin breaking it down. Most often, it's the bacterial breakdown of apocrine sweat that
causes an odor. Management consists of using antiperspirant sprays, deodorants. For best results, apply the
antiperspirant at night to the areas most prone to sweating. Please consult a physician if the symptoms
persist. Since you have an underactive thyroid, it could be a contributing factor. Hope this helps you. Take
care and regards!
