In recent years, with the improvement of living standards, parents are paying more and more attention to their children’s growth and development, and many families are giving their children various supplements, and the number of patients coming to hospitals for precocious puberty clinics is gradually increasing. Some foreign studies have reported that precocious puberty in children may be related to modern diets that favor high fat, high protein, etc., and is caused by excess nutrition or overweight. Under normal circumstances, secondary sexual characteristics such as breast development, pubic hair growth, menstruation, etc. usually appear in girls at the age of 9-10+. In boys, secondary sexual characteristics such as testicular development and beard growth begin to appear around the age of 12. If a girl develops breasts before the age of 8 and a boy develops testicles before the age of 9, he is considered to be precocious and needs medical attention. Most of the patients who come to the hospital only show breast development, but no other precocious features, such as accelerated growth, enlarged gonads and advanced bone age. Most of these patients do not have true precocious puberty, which is caused by transient ovarian activity or increased sensitivity to estrogen, also known as simple breast development, but it may also be a precursor to true precocious puberty, which will gradually transition to true precocious puberty. Precocious puberty in children can result in both psycho-behavioral and physical developmental hazards. Patients may suffer from low self-esteem, fear and anxiety because they are different in size and appearance from their younger peers. Premature menstruation in girls often affects their normal life and studies. Boys may develop early sexual orientation and premature sexual behavior. Because precocious children are often accompanied by accelerated skeletal growth, although they seem to grow faster than others for the time being, they use up the parts that are going to grow later early. The vast majority of precocious puberty can be cured, but early detection and timely treatment are very important. As long as early detection and timely treatment, patients with precocious puberty can achieve a normal psychological state and desired adult height, and the earlier the treatment, the better the results. How to detect precocious puberty in children as early as possible? In addition to observing whether the child has premature secondary sexual characteristics in daily life, the sudden acceleration of height growth before the age of 10 is often a sign of precocious puberty, and parents should not be blindly optimistic at this time. If you suspect that your child has a problem in this area, parents should promptly take your child to the hospital for consultation and medical attention so as not to miss the best time for treatment. If a girl waits until her period starts, or a boy waits until he has a change of voice, laryngeal nodes, or acne to start treatment, it will be too late to improve his height. Therefore, once parents find that their children have symptoms of early development, they must seek medical attention in a timely manner. For those who are not convenient to visit the hospital and some foreign patients, they can first communicate with the specialists by phone to consult about precautions and tests to be done before the visit.
