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 too much (hyperhidrosis) or too little (anhidrosis) — can be cause for concern. Changes in body odor also may signal a health problem.

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.

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.
