What is the sour smell under the armpit?

The sour smell under the armpits is actually a common problem, especially for some people who have larger sweat glands, sweat a lot, and do not pay attention to taking frequent showers and maintaining good hygiene. In this case, the armpits will emit a sour smell, which will have an adverse effect on a person's life, work, and social life. Therefore, we must of course pay attention to understand the causes.

1. Genetic factors

Genetics is the main cause of underarm odor. Clinical investigations show that if both parents have axillary odor, the chance of inheritance can reach 80%, while if only one parent has it, the chance of inheritance is nearly 50%.

2. Metabolic factors

Bromhidrosis mainly occurs from adolescence to middle-aged and elderly people. The secretion of the human body's apocrine sweat glands is related to the gonads. During adolescence, the gonads secrete vigorously, the structure of the apocrine sweat glands develops basically intact, the number increases significantly, and the chance of abnormal secretion will also increase.

3. Personal living and eating habits

If you don't pay attention to hygiene, it will provide an ideal breeding ground for bacteria in your armpits, causing underarm odor; frequent plucking and shaving of armpit hair will damage the normal growth of hair follicles, causing underarm odor; frequent consumption of spicy foods such as alcohol, peppers, garlic, or high-fat foods such as meat and fried foods can easily lead to increased oil secretion, providing bacteria with more and better food, causing them to reproduce vigorously and secrete more fatty acids, causing underarm odor.

4. Mental factors

Mental abnormality leads to changes in hygiene and physiological habits, and high stress and nervous tension lead to abnormalities in the endocrine system, causing body odor.

5. Notes

Pay attention to the cleanliness of your body and armpits, and take a bath frequently. You should quit smoking and drinking, and eat less stimulating foods. During the process, keep a cheerful mood and avoid doing any strenuous activities.
