Why is it that a fat boy has big breasts?

We all know that when men are obese, their breasts will also grow larger. This is mainly caused by the accumulation of fat in the body. If we want to avoid enlarged breasts caused by obesity, we can lose weight through exercise. Male breast hypertrophy can cause breast swelling and pain, as well as breast nodules. It mainly occurs during puberty, because the imbalance of sex hormone secretion at this stage can cause male breast hypertrophy.

Male breast hypertrophy is also known as gynecomastia, which mainly refers to the condition in which men have unilateral or bilateral breast hypertrophy due to different reasons at different stages and ages. In this case, breast swelling and pain, disc-shaped nodules can be felt under the areola, and some even look similar to the breasts of adolescent girls, so it is also called adolescent breast hypertrophy, middle-aged and elderly breast hypertrophy, and idiopathic male breast hypertrophy.

This is a common symptom. The incidence of this disease in the normal population is about 32% to 38%. The incidence rate is even higher during adolescence, reaching 67%. The incidence rate of men over 50 years old is as high as 57%. There is basically no age limit for the onset of the disease. It can occur at almost any age, from seven to eighty-five. And in this case, there is basically no significant difference in the incidence of left and right breasts. Only bilateral breast hypertrophy is more common.

Causes of male breast hypertrophy: Male breast hypertrophy is divided into two types, one is primary male breast hypertrophy, and the other is secondary, and the causes of different types are different.

Primary: More common in children and adolescents, often due to physiological endocrine disorders, the plasma estradiol content is higher than the testosterone content, resulting in a one-time hormone imbalance, or increased sensitivity of breast tissue to estrogen. This situation will naturally subside after puberty. If it continues to enlarge, you need to go to the hospital for diagnosis and treatment.

Secondary: The cause of this condition is more complicated. It may be an endocrine disease, such as low secretion of male hormones, changes in the ratio of testosterone and estrogen in the blood, which can cause male breast hypertrophy. It may also be an adrenal disease such as adrenal cortical hyperplasia, benign tumors, malignant tumors, and functional decline. This type of tumor can directly secrete estrogen or produce too much estrogen precursors, which are converted into effective estrogen in the tissues, thereby causing an increase in blood estradiol and causing male breast hypertrophy.

Liver diseases: such as hepatitis, cirrhosis or liver cancer, these diseases will cause liver function decline, so it will cause breast hypertrophy.

Malnutrition: Malnutrition, especially chronic malnutrition, will cause a decrease in the secretion of gonadal hormones. When the malnutrition is corrected, a phenomenon similar to a second puberty will occur, and breast enlargement will become more serious.

Thyroid disease: Hyperthyroidism, the concentration of neutral hormone-collecting globulin in plasma gradually increases, the bound androgen is excessive, the free estradiol increases, the testosterone ratio increases, and the hormone balance is imbalanced, which leads to the stimulation of breast tissue proliferation and the occurrence of male breast enlargement.
