There is not a specific age when menopause should start. It is estimated that, on average, it begins when the woman is between 45 to 55 years old. Should it begin earlier than age 45, it is considered early menopause. Conversely, in case it you go through it later than age 55, it would be considered a case of late menopause.
The average age for menopause to show up is 51, with symptoms like hot flashes, alterations in the menstrual period, and mood swings.
