If a 13-year-old girl suffers from polycystic ovary syndrome, considering her relatively young age, the use of medication is relatively accompanied by certain side effects and risks, so it is necessary to first adjust the endocrine state from their own habits, so it is necessary to see whether the patient is overweight or too obese. If this is the case, the patient should lose weight, and after the weight comes down, the endocrine function will gradually improve and return to the normal state. So if he is allowed to improve his diet and increase exercise, his weight will be controlled to a normal level in a short period of time, and then the changes in hormone levels will be monitored to see if they return to normal. If the weight comes down, but the improvement of polycystic is not ideal, then consider using drugs to treat polycystic, preferred hormonal drugs with fewer side effects for the best results.
