Pan Dandan, Department of Pediatrics, Affiliated Hospital of Guiyang Medical College: Hello parents! You also need to provide medical history information: 1. birth gestational age, birth weight, birth length, birth with or without rescue history; 2. maternal pregnancy, 3. post-birth feeding, with or without special dietary habits; 4. previous illnesses; plain exercise, sleep; 5. post-birth weight, height growth; 6. intelligent how to, learning; Guizhou Medical University Hospital Pediatrics Pandan 7. parents height, weight, family with or without obesity, shortness; 8. current height, abdominal circumference, hip circumference how much, blood pressure, penis size, breasts, and so on. Parents’ height and weight, whether there is obesity and shortness in the family; 8. present height, abdominal circumference, hip circumference, blood pressure, penis size, nipple lactation; 9. bone age. First, about obesity obesity diagnosis need to be combined with weight, age, and height comprehensive judgment, your child 80kg, unless the body is very high, or should have reached the obesity standard. Diagnosis of obesity is not difficult, but then need to find the cause. Obesity is categorized into simple obesity and secondary obesity. 95% of childhood obesity is simple obesity and secondary obesity. Childhood obesity 95% for simple obesity, that is, there is no disease, is fat, and genetic factors, too much diet, too little exercise and other factors. Secondary obesity is caused by various organic diseases, such as endocrine diseases (hypothyroidism, growth hormone deficiency, hyperadrenocorticism, etc.), genetic metabolic diseases (various obesity-related syndromes), oncological diseases (pituitary, abdominal, and gonadal tumors, etc.), which are often associated with a special body shape, a special face, a short stature, and an intellectual disability, accompanied by the corresponding clinical manifestations of the relevant diseases. The child will have a special body shape, special face, short stature and intellectual disability, with corresponding clinical manifestations of each related disease. If the child is short in stature or has several of the above manifestations, the following examinations are generally recommended: abdominal (including both adrenal glands) ultrasound (to find out whether there is fatty liver and abdominal tumors), testicular ultrasound, saddle MRI (to find out whether there are tumors of the gonads and pituitary gland), bone age (to find out the remaining space for growth), chromosomes (to exclude some hereditary diseases), funduscopic examination, and, if necessary, checking the blood cortisol rhythm, and adrenal androgen, and so on. Regardless of the cause of obesity, obesity can have metabolic syndrome and other adverse consequences of obesity, such as hyperlipidemia, hypertension, hyperglycemia or insulin resistance, fatty liver, obesity cardiorespiratory insufficiency and so on. Therefore, even for simple obesity, it is recommended to complete the following tests: blood tests for liver and kidney function, blood lipids, electrolyte tests, fasting and 2-hour postprandial blood glucose, insulin and C-peptide, etc., urine routine, and monitor blood pressure. If the diagnosis is simple obesity, there is no special treatment drugs, mainly diet therapy and exercise therapy (simple to say, not easy to do treatment). Parents can go online and type: www.cxcz123.com in the address bar, search, visible pediatric endocrinology of the First Affiliated Hospital of Zhejiang University School of Medicine online web page, click on the activity window “fast track” in the “weight calculation”, it will display “Individualized lifestyle intervention software for obese children”, according to the requirements to fill in the child’s relevant projects, there will be more detailed diet and exercise guidance. General obese children without primary disease first adjust the diet, strengthen the exercise for 3 months, under the premise of ensuring growth and development, control weight growth, so that the weight gradually drop to no more than 20% of the normal height and weight indicators. If ineffective, in insulin resistance and other metabolic abnormalities such as syndrome of obese children older than 10 years old, can be in the pediatric endocrinologist under the guidance of trial metformin treatment. As parents can tell from the above, a full set of tests for an obese doll is extensive and costly, and the final results come down, as doctors and parents hope, that there is nothing wrong with most children. However, there is a risk of assuming that your child is not sick without doing any tests. It is recommended that you take your child’s specific situation into account, and if appropriate, perform some tests first to rule out obvious diseases, and then decide on the next treatment plan after 3 months of active diet and exercise therapy. Second, about “small testicles” normal pre-pubertal boys testicular volume of 3ml or less, after the age of 14 years old testicular development is still not known as delayed pubertal development. Your child is less than 14 years old, “small testicles” does not necessarily mean that there is a problem. Third, on the “big breasts” obese children breast fat accumulation can be similar to female breast development, feasible breast ultrasound clear. If the boy’s testicles have not developed and breast development, we need to find the cause, to exclude heterosexual precocious puberty and other pathological factors.
