Sweating and body odor are common when you exercise or you're too warm. They're also common when you're feeling nervous, anxious or stressed.
Unusual changes in sweating — either excessive perspiration (hyperhidrosis) or little or no perspiration (anhidrosis) — can be cause for concern. Changes in body odor also may signal a health problem.
Otherwise, lifestyle and home treatments can usually help with normal sweating and body odor.
Some people naturally sweat more or less than other people. Body odor also can vary from person to person. See a doctor if:
Sweating and body odor are caused by sweat glands in your body. The two main types of sweat glands are eccrine glands and apocrine glands. Eccrine glands occur over most of your body and open directly onto the surface of the skin. When your body temperature rises, these glands release fluids that cool your body as they evaporate.
Apocrine glands are found in areas where you have hair, such as your armpits and groin. These glands release a milky fluid when you're stressed. This fluid is odorless until it combines with bacteria on your skin.
To diagnose a problem with sweating and body odor, your doctor will likely ask about your medical history and do an exam. The doctor may test your blood or urine. The tests can show if your problem is caused by a medical condition, such as an infection, diabetes or an overactive thyroid (hyperthyroidism).
If you're concerned about sweating and body odor, the solution may be simple: an over-the-counter antiperspirant and deodorant.
If over-the-counter antiperspirants don't help control your sweating, your doctor may prescribe a prescription product. These are strong solutions that can cause red, swollen and itchy skin in some people.
