Some women feel very few side effects. However, others may experience an increasing number of menopausal symptoms as estrogen levels drop rapidly. Symptoms include irregular periods, hot flashes, increased PMS, fatigue, vaginal dryness, mood swings, tender breasts, and a lowered libido. Vertigo or dizziness, acute anxiety, and feelings of an impending disaster have also been reported in some instances.
Suggested treatments include some birth control treatments (to alleviate hot flashes) and antidepressants (to reduce mood swings). Exercising, quitting smoking, and reducing alcohol intake are also recommended.
Fertility declines during perimenopause, however, it is still possible to get pregnant during this period, and birth control should be used until the onset of menopause.
A doctor can usually assess symptoms to diagnose perimenopause, and a blood test assessing hormone levels may confirm the diagnosis. Due to hormonal fluctuations, several blood tests may be required.
