How to do when a 16-year-old has a long and light menstrual period

Patient's question:

16 years old, in high school, irregular menstrual cycle, about 10 days each period with light flow, what is the reason? Need an ultrasound examination? Also, many small pimples on the face

Doctor's answer:

Irregular menstruation has many causes, which are typically divided into two major categories in clinical practice: one is functional, such as menstrual irregularity caused by endocrine dysfunction; the other is organic, such as conditions like pelvic inflammatory disease, endometritis, and endometriosis, which can also lead to menstrual irregularity.
Go to the hospital for a check-up and take medication based on your symptoms. In your daily diet, consume more foods that boost qi and blood, or traditional Chinese medicine herbs for regulating menstruation, such as angelica sinensis (Danggui), astragalus (Huangqi), and Leonurus japonicus (Yimucao). Drink plenty of water, eat less spicy and irritating foods, pay attention to a balanced diet, and exercise more.
Wishing you good health.
