The incidence of body odor is related to apocrine glands, which belong to skin appendages, so body odor belongs to dermatology, so it depends on dermatology. Body odor can go to the dermatology department of a regular hospital. Body odor is mainly caused by abnormal sweat glands under the armpit, which leads to abnormal secretion and is decomposed by bacteria on the body surface, forming a pungent smell. Generally speaking, teenagers are in a period of vigorous development, their endocrine function is constantly improving, and the apocrine glands are also increasingly developed under the action of hormones. Some people sweat mostly because of abnormal development of apocrine glands, and fatty acids in sweat give off a pungent smell under the decomposition of bacteria on the skin surface, which is what people call body odor. The removal of body odor can be treated surgically or non-surgically, and the operation is mainly to remove apocrine glands. Usually pay attention to food hygiene, take a bath frequently, and avoid spicy and irritating food.
