Why does precocious puberty occur?

Precocious puberty is not unfamiliar to us, but many people may not have heard of precocious sexual puberty. This disease mostly occurs in children, and even newborn babies may suffer from it. It’s just that the symptoms after suffering from it are not very obvious, so it is difficult to be discovered in the first time. In this case, there is no way to know the cause of precocious sexual puberty.

Excessive light exposure is one of the important reasons for inducing precocious puberty in children, because light affects the normal functioning of the pineal gland, an endocrine organ in the brain. One of the functions of the pineal gland is to secrete a large amount of melatonin at night when the human body enters a sleep state. This hormone is secreted most vigorously from 11 pm to the early morning of the next day, and stops secreting when there is light after dawn.

The pineal gland has a characteristic that as long as the eyeball sees the light source, melatonin will be suppressed or stop secreting. If children are exposed to too much light, the secretion of melatonin in the pineal gland will be reduced, causing sleep disorders, which may lead to the early secretion of follicle-stimulating hormone, thus leading to precocious puberty. The incidence of precocious puberty in children is increasing year by year, but less than 10% of them are actually caused by diseases. 90% of children's precocious puberty is affected by external factors. Excessive light stimulation should be taken seriously, especially when children sleep at night. If there are no special circumstances, it is best not to turn on the lights and try to ensure adequate sleep. In addition, avoid long-term light stimulation from computer monitors to avoid causing precocious puberty.

Primary hypothyroidism

2. Peripheral precocious puberty

Also known as pseudo-precocious puberty, it is a precocious puberty caused by hypothalamus-pituitary gonadal function. There is secondary sexual characteristics development and increased sex hormone levels, but the hypothalamus-pituitary-gonadal axis is immature and there is no gonadal development.

1. Gonadal tumors

Ovarian granulosa-thecoma cell tumor, luteal tumor, testicular stromal cell tumor, teratoma, etc.

2. Adrenal gland disease

Adrenal tumors, congenital adrenal hyperplasia, etc.

3 Exogenous

Such as drugs, food, cosmetics containing estrogen, etc.

4 Others

McCune-Albright syndrome

3. Partial precocious puberty

Simple premature breast development Simple premature pubic hair development Simple premature menarche

(IV) Some cases of precocious puberty are caused by tumors in the body. These tumors can secrete substances similar to sex hormones. Sometimes, when the tumor is still small, the amount of sex hormones it secretes is already large enough to cause sexual development. Therefore, children with precocious puberty must see a doctor in time for diagnosis and treatment as soon as possible.

The above article gives you a detailed introduction to the reasons why precocious puberty occurs. In fact, this disease of precocious puberty may be caused by sleeping with the lights on for a long time, or watching overly adult TV dramas when the child is a child, which is particularly likely to cause precocious puberty.
