What is the reason for less menstruation?

Less menstruation may be caused by ovarian hypofunction, polycystic ovary syndrome, intrauterine adhesions, abnormal thyroid function, excessive mental stress, etc. If it is accompanied by symptoms such as amenorrhea and hot flashes, it is recommended to seek medical attention promptly to check hormone levels and pelvic ultrasound.

1. Decreased ovarian function

Decreased ovarian reserve function will lead to reduced estrogen secretion and insufficient endometrial hyperplasia, which is manifested by a gradual decrease in menstrual flow. It is common in women over 40 years old and may be accompanied by symptoms such as hot flashes and insomnia. It is necessary to pass six sex hormone and AMH test evaluations. If necessary, you can use estradiol valerate tablets, progesterone capsules and other drugs for hormone replacement therapy as directed by your doctor.

2. Polycystic ovary syndrome

Hyperandrogenism and ovulatory disorder can lead to oligomenorrhea and reduced menstrual flow, often accompanied by hirsutism, acne and other symptoms. Ultrasound shows polycystic changes in the ovaries. Treatment requires the use of ethinyl estradiol and cyproterone tablets to regulate the cycle and metformin tablets to improve insulin resistance as directed by the doctor.

3. Uterine adhesions

Endometrial damage caused by artificial abortion, uterine cavity manipulation, etc. can cause intrauterine adhesions, manifested as a sharp decrease in menstrual flow or even amenorrhea. Hysteroscopy is the gold standard for diagnosis. Mild adhesions can be treated by hysteroscopic separation, and estradiol gel needs to be used to promote endometrial repair after surgery.

4. Abnormal thyroid function

In hypothyroidism, metabolism slows down, which affects the function of the hypothalamic-pituitary-ovarian axis, resulting in reduced menstrual flow. Patients often suffer from symptoms such as sensitivity to cold and fatigue, and their TSH levels need to be tested. After diagnosis, follow the doctor's instructions to take levothyroxine sodium tablets to supplement the hormone.

5. Excessive mental pressure

Emotional stress such as long-term anxiety and tension can inhibit the secretion of GnRH in the hypothalamus and cause temporary reduction in menstrual flow. Improving sleep quality and exercising appropriately can help relieve symptoms. If necessary, Wuling Capsules can be used for a short period of time to regulate nerve function.

It is necessary to maintain a regular daily routine, avoid excessive dieting and weight loss, and pay attention to keeping warm to avoid uterine cold. You can add foods with high phytoestrogen content, such as soy products and nuts, to your diet in moderation, and avoid strenuous exercise during menstruation. If the menstrual flow continues to decrease for more than 3 months, or is accompanied by severe headaches, vision changes and other symptoms, you must go to a gynecological endocrinology department as soon as possible to check for organic diseases.
