What to do if a 7-year-old boy has precocious puberty

Precocious puberty in 7-year-old boys can be intervened through lifestyle adjustment, psychological intervention, drug treatment, traditional Chinese medicine conditioning, and regular monitoring. Precocious puberty may be related to genetics, overnutrition, environmental hormone exposure, central nervous system abnormalities, adrenal gland or testicular disease, and other factors.

1. Lifestyle adjustment

Control the intake of high-calorie foods and avoid fried foods, sugary drinks and out-of-season fruits and vegetables. Ensuring 60 minutes of outdoor exercise every day, such as rope skipping, basketball and other longitudinal exercises can help delay the progression of bone age. Establish a regular schedule and ensure that you fall asleep before 21 o'clock every day to avoid abnormal melatonin secretion stimulated by light sources at night.

2. Psychological intervention

Parents need to explain physical changes in a calm manner to avoid children feeling ashamed. Sex education can be provided through age-appropriate books such as the picture book Little Secrets of the Body. School teachers should pay attention to their social situations and prevent school bullying caused by developmental differences.

3. Drug treatment

Gonadotropin-releasing hormone analogs such as leuprolide acetate sustained-release microspheres can inhibit gonadal axis activation. Commonly used dosage forms include 3.75 mg/tube powder for injection. Growth hormones such as recombinant human growth hormone injection can improve final height and require strict monitoring of thyroid function and blood sugar levels.

4. Traditional Chinese Medicine Conditioning

For the type of liver and kidney yin deficiency, Zhibai Dihuang Pills can be added or subtracted, and for the type of spleen deficiency and phlegm-dampness, Erchen Decoction combined with Baohe Pills can be used. Auricular acupoint sticking and pressure selects endocrine, kidney, spleen and other acupoints, and changes them twice a week. Massage can be done by rubbing the two people on the horse, clearing the river water, etc., for 20 minutes a day.

5. Regular monitoring

Measure height and weight growth every 3 months, and assess bone age no more than once a year. When the testicular volume reaches 4 ml, hormone levels need to be reviewed. For Tanner stage II breast development, a GnRH stimulation test is recommended. Magnetic resonance examination excluded organic lesions such as hypothalamic hamartoma.

Avoid daily contact with bisphenol A plastic products and stationery containing phthalates, and choose pure cotton underwear to reduce local friction. Keep a diary of developmental progress, including the time points for changes in secondary sexual characteristics such as voice change and pubic hair appearance. Ensure that 500ml of milk is provided daily to supplement calcium, and maintain vitamin D3 intake above 400IU. If the annual growth rate exceeds 6 centimeters or the bone age exceeds 2 years, you should promptly go to the pediatric endocrinology department for follow-up consultation.
