What medicine is better to take for menstrual disorders?

Patient's question:

Gender: Female
Age: 21
Sleeping poorly, often dreaming, and also having bowel problems. Gained 10 pounds in a year.
Past treatment history and effectiveness:
After a check-up, it was said that it was menstrual disorder. Taken Chinese patent medicine, but the effect was not very good.
What should be noted?

Doctor's answer:

Poor quality of deep sleep and frequent dreaming are primarily caused by reduced excitability of the cerebral cortex. However, they can also be due to excessive stress or other physical conditions. Bowel issues are also relevant—whether your bowel movements have become more frequent or constipated? This is related to gastrointestinal dysfunction. Gaining 10 pounds in a year is excessive and may be linked to your dietary habits. Irregular menstruation should be considered in terms of your usual cycle length, flow volume, and other factors. If hormonal imbalance occurs during your period, weight loss may not be as pronounced. You should undergo further detailed examinations to identify the reasons for your weight gain.
