What is the reason for delayed menstruation?

Menstruation refers to the menstrual cycle of women. In addition to considering irregular menstruation, other factors should also be considered when the menstrual cycle is abnormal. Delayed menstruation is a problem that most women have, and the causes are varied. Some gynecological diseases may also cause delayed menstruation.

1. Neuroendocrine dysfunction causes:

The main problem is that the function of the hypothalamus-pituitary-ovarian axis is unstable or defective, that is, menstrual disease.

2. Cervical adhesions:

There is menstrual blood, but the menstrual blood cannot be discharged normally due to adhesion of the cervix and accumulates in the uterus. The patient will have periodic abdominal pain. B-ultrasound examination can show dark areas in the uterine cavity, and the patient often needs to go to the hospital for cervical dilation. If this situation is not improved in time, it will lead to endometriosis.

3. Premature ovarian failure:

It is caused by abnormal ovarian function. It often manifests as delayed menstruation, infrequent menstruation, amenorrhea and infertility. Symptoms similar to menopause such as vaginal dryness, dyspareunia, hot flashes and insomnia may occur.

4. Side effects of drugs:

Endocrine disorders after long-term use of contraceptives can also cause delayed menstruation.

5. Polycystic ovary syndrome:

In addition to infrequent menstruation, it also has three other characteristics: anovulation, obesity, and hirsutism. This disease can not only cause irregular menstruation and infertility, but also is likely to increase the risk of hypertension, diabetes, and endometrial cancer.

6. Abnormal thyroid function:

Thyroid problems seem to be more common in women. Whether it is hyperthyroidism or hypothyroidism, it will affect menstruation. When the thyroid gland is overactive, the frequency and volume of menstruation decreases, and the time between periods becomes longer. When the thyroid function is low, the menstrual blood increases and the bleeding time is prolonged, but patients with long-term illness will have less menstruation or even no menstruation.
