There are significant individual differences in the duration of perimenopause in women, with most women lasting 1-2 years, while some may last 10-20 years. Common symptoms include irregular menstruation, hot flashes, sweating and emotional instability. Perimenopause refers to the period from the decline of ovarian function until 1 year after menopause. When a woman is in perimenopause, the ovarian function will gradually decline and the secretion of estrogen will gradually decrease, which may lead to some perimenopausal discomforts, such as gradual irregular menstruation, hot flashes, night sweats, dizziness, headache, insomnia, lack of concentration, and mood swings. When a woman is in perimenopause, it is recommended to face it with an optimistic mindset, appropriate physical exercise, healthy diet, sunbathing more often, and adequate intake of protein and calcium. If the symptoms of perimenopause are obvious, it is recommended to consult a doctor in time for symptomatic treatment.
