Menopause symptoms, which lead to significant changes in a woman’s life similar to those experienced during infancy or adolescence, manifest in different ways. This process, which spans three different stages known as “Premenopause,” “Menopause,” and “Postmenopause,” leads to a halt in estrogen production due to a decrease in the number of follicles in the ovaries.
In the final stage, estrogen production stops completely, the ovaries shrink, and the menstrual cycle ends, resulting in the loss of reproductive ability.
What is Menopause?
Menopause is a biological and natural process that signifies the end of a woman’s menstrual cycles. It is generally diagnosed after a woman has gone 12 consecutive months without a menstrual period. The transition period from the reproductive and menstruation phase to menopause is called perimenopause.
The term “perimenopause” means “around menopause” and helps to describe the condition of women who begin to experience this process in their 30s, in contrast to those who enter menopause in their 40s or 50s.
Is There a Specific Age for Menopause?
The age at which menopause occurs varies depending on genetic and environmental factors. When asked, “What is the average age for menopause?” statistics indicate that it generally occurs between 45-55 years worldwide, and between 46-48 years in our country. While menopause naturally manifests at these ages, it can also occur earlier or later due to various reasons.
Menopause is classified into three different groups based on its onset: “natural,” “early,” and “surgical.” Natural menopause, as described by WHO statistics, typically occurs between the ages of 40-50.
Early menopause refers to the onset of menopause before the age of 45. Causes can include unknown factors, autoimmune diseases, radiotherapy, chemotherapy, infections, environmental factors, abortions and miscarriages, obesity, and hypothyroidism.
Factors triggering early menopause can be divided into genetic and environmental categories. Genetic triggers include family history of menopause at similar ages, severe metabolic diseases, and irregular menstrual cycles. Environmental triggers include heavy smoking, geographic location, psychological traumas, and climatic conditions.
Some women may experience menopause earlier than usual due to surgical procedures. For instance, if a menstruating woman’s ovaries are surgically removed, her menstruation will cease, and menopause will occur. Additionally, radiation treatments can also lead to menopause.
What are the Symptoms of Menopause?
Menopause symptoms and signs can vary widely among women, including changes in the menstrual cycle. During the perimenopause phase, which encompasses the transition from regular reproductive and menstrual periods to menopause, women may experience a range of symptoms over the months or years leading up to menopause. These symptoms can include, but are not limited to:
- Skin dryness
- Night sweats
- Weight gain
- Slowed metabolism
- Loss of breast fullness
- Sudden mood swings
- Thinning hair
- Vaginal dryness
During the perimenopause stage, missed periods are common and expected. Often, menstrual periods may skip a month and then return, or they might skip several months and then resume. Additionally, menstrual cycles may tend to become shorter.
Despite irregular menstrual cycles, it is still possible to become pregnant. Therefore, healthcare professionals recommend that women who miss a period but are unsure about starting menopause should take a pregnancy test. However, if there is vaginal bleeding after the menopause process has ended, it is crucial to seek medical advice. Early intervention and diagnosis can benefit the treatment process.
What Causes Menopause?
Various factors can trigger menopause, but the most common cause is the natural decline in reproductive hormones due to aging. As women approach their late 30s, their ovaries start to produce less estrogen and progesterone, the hormones that regulate menstruation. This decline leads to reduced fertility.
A hysterectomy, in which the uterus is removed but the ovaries are left intact, usually does not cause immediate menopause. Although the woman no longer has periods, her ovaries still produce estrogen and progesterone.
However, a total hysterectomy, which involves the removal of both the uterus and ovaries, can directly cause menopause. This results in the immediate cessation of menstrual periods. Because the hormonal changes that would normally occur over several years happen abruptly, severe hot flashes, pain, and other menopause symptoms are likely to occur.
Early menopause, or primary ovarian insufficiency, affects about 1% of women before the age of 40. This condition can be caused by genetic factors or autoimmune diseases that prevent the ovaries from producing normal levels of reproductive hormones.
In many cases, the cause of early menopause is unknown. When this condition occurs, doctors often recommend hormone therapy until the natural age of menopause to protect the health of the brain, heart, and bones.
