Perimenopause is a natural part of every woman's life and is characterised by hot flashes, insomnia, memory loss, mood swings, bone loss, irregular periods, excessive sweating, reduced fertility, and decreased libido. Many perimenopausal women today have demanding jobs and, in many cases, young children, which makes the symptoms unbearable.  Modern medicine, of course, cannot pass up an opportunity to make a buck and offers products that supposedly make the transition to menopause easier but actually cause more health problems.
