How many years does a woman have amenorrhea?

Menstruation first appears in women around the age of 13 and will accompany them for most of their lives. Therefore, women’s menstrual condition is a problem they are more concerned about, especially amenorrhea. They want to know the age at which amenorrhea occurs. However, the timing of women's menopause is affected by many factors and is not necessarily fixed. So, at what age does a woman begin menopause? Let’s take a closer look.

At what age do women have to stop menstruating? For women who stop menstruating before the age of 40, the risk of death is 39% higher than that of women who stop menstruating at 40-44 years old, 60% higher than that of women who stop menstruating at 45-49 years old, and 95% higher than that of women who stop menstruating at 50-54 years old. Therefore, understanding the various factors that affect menopause and delaying the age of menopause are issues that cannot be ignored in the health care of middle-aged and elderly women.

The most important factor determining a woman's age of menopause is the number of oocytes. When a baby is born, there are about one million oocytes in each ovary, and the number of oocytes continues to decrease after birth. When the number of oocytes decreases to a critical number, menopause will occur. The mechanism that controls or regulates the rate of oocyte reduction is not yet fully understood, but the following factors are clearly related to the early or late onset of amenorrhea.

The age at which women reach menopause is closely related to nutrition: compared with women with long-term malnutrition, short stature and light weight, the average age of menopause is 43.6 years old, while that of women with better nutrition, relatively tall stature and relatively heavy weight is 47.3 years old.

Smoking is an important factor in early age of menopause. Benzopyrene in cigarettes is a lethal factor to oocytes. Animal experiments have confirmed that a small dose of benzopyrene can destroy 25% of oocytes, while a large dose of benzopyrene can destroy 98% of oocytes. Women who smoke enter menopause 54 years earlier than non-smoking women on average.

Disease: It is generally believed that chronic wasting diseases, metabolic and endocrine diseases, tumors, mumps complicated with oophoritis, etc. can all cause ovarian dysfunction, abnormal secretion of hormones such as adrenal cortex, thyroid, pituitary gland, etc., and premature menopause.

Radiation therapy can also cause premature menopause in women. Chemotherapy and some autoimmune diseases can also cause premature ovarian failure and amenorrhea.

The age of menopause is also related to various mental and psychological factors. Women who have harmonious marital relationships and harmonious sex lives reach menopause relatively later than women who have disharmonious marital relationships, indulge in lust or lack sex lives. Especially for women who suffer from mental and psychological stress, overwork, long-term depression and anxiety, their neuroendocrine function may be affected and they may experience premature menopause.

The average age of menopause for urban women is 49.5 years old, while that for rural women is 47.5 years old. In the late century, the age of menarche has tended to be earlier, but the age of menopause has not changed significantly. Amenorrhea before the age of 40 is called premature amenorrhea or premature ovarian failure.

The above is an introduction to the age at which women experience menopause. Women should be clear about this. The time of female amenorrhea is not fixed, and there are many factors that cause female amenorrhea, many of which are caused by other diseases. When it is discovered, it is necessary to go to a regular hospital for diagnosis in time, find the cause and actively treat it to avoid greater harm.
