Premenopause, or perimenopause, is a transitional period before menopause, during which the secretion of sex hormones changes. This phenomenon is related to the depletion of ovarian follicles associated with a progressive decrease in the secretion of progesterone and estrogen. It lasts a few years and starts in women between the ages of 40-45. Even if periods become irregular or stop completely, there is still a possibility of pregnancy. One must therefore be vigilant. This phenomenon affects the majority of women, but some are little prone to symptoms.


The symptoms of perimenopause are:
  • irregular menstrual periods;
  • hot flashes;
  • headaches;
  • pain in the chest and pelvis;
  • excessive secretion of sweat;
  • irritability;
  • sleep disorders;
  • a tendency to suffer from fatigue, depression sometimes moodiness.


The diagnosis of perimenopause is made through an interview and a physical examination. Hormone levels are very unstable, blood tests are rarely done and only measurements rate FSG or estrogens are occasionally made.


Treatments administered in premenopause aim to relieve symptoms and not to delay menopause. They will be prescribed only when the symptoms have a significant impact on the life of the patient. This will consist of rebalancing the dosages of estrogen and progesterone using hormone replacement therapy.
