• Vaginal dryness and skin
• Minor psychological disorders (depression, fatigue, insomnia, decreased libido, etc)
• Hot flashes, especially with night sweats often associated
• Final Amenorrhea (cessation of blood flow)
• Asthenia with insomnia
• Accelerated loss of bone density, making up an osteoporosis
• Weight gain. Average of 3 to 15 kg

Later, the genitals (vagina, vulva, uterus) atrophy and mammary glands, with accentuation of prolapse.

All these symptoms are only disadvantages. The risks of osteoporosis (decreased bone density: fracture risk and therefore most important repair more difficult and longer; accentuated bone loss at menopause) and increased cardiovascular disease.

Weight gain is not due to menopause per se but to the significant decrease of basal metabolism which occurs at approximately the same period
