If you have a low menstrual volume and acne when your period comes, you are considering a disorder of endocrine hormone level metabolism, most of which are considered to be polycystic ovary syndrome. Polycystic ovary syndrome is mainly a disorder of endocrine hormone level, which is mainly manifested by clinical symptoms such as abnormal menstruation, scanty menstrual flow, body fat, hirsutism and frequent acne on the face. Low menstrual flow is mainly due to the relatively low level of estrogen and progesterone in the body, resulting in the normal growth and shedding of the endometrium, leading to low menstrual flow and, in severe cases, amenorrhea or functional bleeding of the uterus. Acne is a chronic inflammation of the sebaceous glands of hair follicles and is often related to high levels of androgens in the body, leading to frequent acne. Therefore, if you have low menstrual flow and frequent acne, you need to consider going to the hospital to have your female sex hormone six indicators checked and androgen secretion measured, which can basically clarify the diagnosis, and then consider targeted symptomatic treatment.
