Precocious puberty is a disruption of the endocrine system due to the influence of certain factors on the brain and hypothalamus during the growth and development of the child. This can be seen as breast enlargement and menstruation in girls before the age of 8, and throat nodes, armpit hair and voice changes in boys before the age of 9. This is what you need to think about when you think of precocious puberty and take your child to the hospital for a checkup. Precocious puberty is divided into true precocious puberty, pseudo precocious puberty, and partial precocious puberty, which can be caused by brain lesions, tumors of the adrenal glands, improper diet, and misuse of birth control pills. You should take your child to the hospital to check the level of sex hormones, do cranial MRI, adrenal ultrasound, bone age and other tests. Prevent giving your child less honey, protein powder, colostrum, soy milk, milk drinks with artificial additives, juice drinks, anti-seasonal vegetables and fruits, less high-calorie fried food, take your child out for a walk more often for exercise and drink more plain water.
