What are the causes of irregular menstruation?

Irregular menstruation is a common gynecological disease, manifested as abnormal menstrual cycle or bleeding. The cause may be organic disease or functional disorder, which may be affected by many factors.

The main causes of irregular menstruation are as follows:

1. Neuroendocrine dysfunction: mainly the instability or defect of the hypothalamus-pituitary-ovarian axis, that is, menstrual disease.

2. Ovarian problems: Irregular menstruation in women of childbearing age is generally due to poor ovarian corpus luteum function, which often manifests as cyclical, but shortened cycles, or heavy menstrual bleeding.

3. Organic diseases or drugs: including local inflammation, tumors, developmental abnormalities, malnutrition, intracranial diseases, thyroid and adrenal cortex dysfunction, diabetes, Sheehan's disease and other endocrine dysfunctions; liver disease, blood diseases, etc.

4. People who use drugs for the treatment of mental illness, endocrine preparations or intrauterine contraceptive devices may experience irregular menstruation. People in certain professions, such as long-distance runners, are prone to amenorrhea.

5. Reasons for irregular menstruation after childbirth: The most common reason is that breastfeeding inhibits ovarian ovulation and delays the resumption of menstruation after childbirth. Generally speaking, irregular menstruation after childbirth is normal for women. Irregularity may occur in the first few times after childbirth, but it will gradually return to normal.

6. Psychological and emotional reasons: Emotions are often unstable and prone to anxiety, depression or excessive mental stress leading to depression. You may unknowingly find that your menstrual patterns are abnormal or even long-term amenorrhea.
