Characteristics of irregular menstruation caused by menopausal functional uterine bleeding

Dysfunctional uterine bleeding is one of the common gynecological diseases, about 50% of which occur during menopause. If menopausal women have irregular menstruation, and after examination, pregnancy, tumors, inflammation, trauma and blood system diseases are ruled out, and it is confirmed that there is no intrauterine device in the uterus, it can be diagnosed as menopausal functional uterine bleeding. Dysfunctional uterine bleeding is caused by neuroendocrine disorders, and is mainly manifested as irregular menstruation, including changes in menstrual cycle and volume, with the following characteristics:

Irregular menstrual cycles

One is a shortened menstrual cycle, and the other is a prolonged menstrual cycle. Prolonged menstrual cycle is more common. Generally, the longest one is 40-50 days, or even more than 2-3 months, and the shortest one is twice a month, or amenorrhea and regular menstruation alternate.

Irregular menstrual periods

The duration of the menstrual period changes, with the period being prolonged or shortened, with prolongation being the most common, often lasting more than ten days or longer.

Changes in menstrual flow

The menstrual volume increases or decreases, with an increase being more common; the menstrual blood is light red, dark red or purple, or accompanied by blood clots or fibrous tissue. Accompanied by large blood clots and heavy bleeding, severe cases may cause anemia symptoms such as palpitations and dizziness.

Menstrual cycle changes, abnormal menstruation, and abnormal menstrual volume caused by menopausal dysfunctional uterine bleeding may occur at the same time, or two or one of them may be abnormal. For example, the cycle is normal but the menstrual volume is abnormal, or the cycle is shortened or irregular but the menstrual volume is reduced, and the menstrual period is prolonged.
