Menopause (also known as the climacteric) marks the end of a woman's reproductive life and is officially diagnosed after she has gone 12 consecutive months without a menstrual period. While it typically occurs around age 51, the transition leading up to it, known as perimenopause, often begins around age 46. During this phase, menstrual cycles become irregular—becoming heavier, lighter, longer, or shorter—as the body begins to undergo significant hormonal shifts.

Physiological Changes

The primary driver of menopause is the decline in estrogen levels. As women age, their ovaries produce fewer eggs, causing estrogen production to fluctuate and eventually drop. This hormone is crucial because it controls the menstrual cycle and affects various organs, including the brain, skin, and muscles. Other hormones, such as progesterone and testosterone, also decrease during this time. While their impact is less dominant than estrogen's, the drop in testosterone can lead to lower energy levels and a reduced sex drive.

Key Symptoms

Menopause affects every woman differently; approximately 75% of women experience symptoms, and for about one-quarter, these symptoms are severe. Common indicators include:

• Vasomotor symptoms: Hot flashes and night sweats, caused by the brain's "thermostat" malfunctioning due to low estrogen.

• Physical changes: Vaginal dryness, bladder problems, joint pain, and dry skin.

• Cognitive and emotional shifts: Often referred to as "brain fog," many women experience memory and concentration issues, as well as irritability, anxiety, and low mood.

• Long-term health impacts: Decreased estrogen can eventually affect bone density and heart health.

Management and Treatment

There are several ways to manage the discomfort associated with menopause:

• Hormone Replacement Therapy (HRT): This involves supplementing estrogen (sometimes with progesteron) to stabilize hormone levels. However, it may not be suitable for women with a history of certain cancers, blood clots, or high blood pressure.

• Lifestyle Adjustments: A calcium-rich, low-fat diet and regular physical activity can protect the heart and bones while reducing stress. Quitting smoking and limiting alcohol may also reduce the frequency of hot flashes.

• Alternative Options: Some studies suggest that plant-based estrogens (like soy or red clover) and Vitamin D supplements can be beneficial. Cognitive Behavioral Therapy (CBT) is also recommended for some women to help manage the psychological impact of the transition.

Diagnosis and Duration

Symptoms last an average of seven years, though they can persist longer for about a third of women. Experts generally advise against using diagnostic blood tests (which measure FSH levels) for women over 45, as hormone levels fluctuate too wildly to provide an accurate reading. Instead, a clinical conversation with a healthcare professional regarding menstrual patterns and symptoms is considered the most effective way to monitor the transition. It is also important to note that women can still become pregnant if their periods are irregular, and contraception is typically recommended until age 55.
