What are the changes in menstruation before menopause?

What are the symptoms of premenopause in women? Menopause is an issue of concern to middle-aged women. Menopause usually heralds the onset of menopause in women. When menopause is approaching, menstrual conditions will usually change as well. So what changes occur in the menstrual period before menopause?

Generally speaking, there are three types of symptoms from ovarian decline to the end of menstruation, that is, premenopausal symptoms:

1. Infrequent menstruation

The menstrual cycle time is longer, from the normal 20 to 30 days to 2 to 3 months or longer. The menstrual flow may be normal or lower than before, and the interval gradually increases to once every 4 to 5 months or half a year, and then stops completely.

2. Disruption of menstrual cycle

The normal menstrual cycle becomes regular vaginal bleeding, and sometimes the menstruation is prolonged or becomes continuous vaginal bleeding, which lasts for more than 1 to 2 months; there may also be heavy vaginal bleeding, and the patient may develop anemia, sallow complexion, general fatigue, panic, chest tightness and shortness of breath. In severe cases, hemoglobin concentration may drop sharply. Some women have recurrent bleeding, but generally after 1 to 2 years, the menstrual period stops completely. At this time, the doctor needs to conduct a detailed examination, first of all, to check for bleeding caused by other tumors. For women over 40 years old, a comprehensive examination or a uterine wall biopsy should be performed.

After the tumor is diagnosed, the menopausal menstrual disorder is treated accordingly. Disrupted menstrual cycles are most common before menopause. Researchers observed 282 premenopausal women and found that 181 of them had menstrual cycle disorders, accounting for 63.8%.

3. Sudden menopause

A small number of women have had normal menstrual cycles and periods in the past, but now suddenly go into menopause; some women have normal cycles, with only a few episodes of gradual decrease in menstrual flow, followed by a sudden cessation of menstruation. A study of 282 women with natural menopause found that 40 of them had sudden menopause, accounting for 14.1%. Therefore, most of them are the first two manifestations.

Another part of patients mainly show abnormal uterine bleeding after a period of amenorrhea, which lasts for 2 to 4 weeks. The amount of blood and the duration of the bleeding are related to the duration of estrogen action and the withdrawal rate.

The diagnosis of menopause can only be confirmed in retrospect, and the diagnosis can be established if the absence of menstruation lasts for at least 6 months to 1 year.
