Short answer: perimenopause is the transition before menopause when your ovaries produce less regular hormones. You’re likely in perimenopause if you have changing menstrual patterns plus typical symptoms (see below). A clinician can confirm and rule out other causes. What to look for Menstrual changes: cycles get shorter or longer, heavier or lighter, or skip periods. Pattern becomes unpredictable. Vasomotor symptoms: hot flashes and night sweats. Sleep problems and fatigue. Mood changes: irritability, anxiety or low mood. Vaginal dryness, discomfort with sex, or decreased libido. Other: breast tenderness, headaches, urinary frequency/urgency, trouble concentrating or memory slips. Typical age and timing Most people start perimenopause in their 40s (can start late 30s or earlier). Perimenopause can last months to several years; menopause is defined as 12 consecutive months without a period. How it’s diagnosed Largely clinical: your symptoms and changes in bleeding pattern are the main clues. Tests that may be done: pregnancy test (if applicable), TSH (to rule out thyroid), CBC if heavy bleeding, and sometimes FSH and estradiol. FSH can fluctuate and may not be definitive in early perimenopause. Imaging (pelvic ultrasound) or referral to gynecology may be needed for abnormal/heavy bleeding to exclude fibroids, polyps, or other conditions. When to see a clinician sooner Very heavy bleeding (soaking through pads/tampons in an hour), bleeding between periods or after sex, severe symptoms affecting daily life, or if you’re under 45 with new irregular bleeding. Also see a clinician to discuss contraception — pregnancy is still possible during perimenopause until menopause is confirmed. What can help (brief treatment options) Lifestyle: cool strategies for hot flashes, sleep hygiene, regular exercise, limit caffeine/alcohol/smoking, weight management. Vaginal dryness: OTC lubricants (K-Y, Astroglide) or Replens; prescription vaginal estrogen (Estrace cream, Estring) if needed. Systemic hormone options for bothersome hot flashes or heavy symptoms: menopausal hormone therapy (transdermal estradiol patches like Climara or Vivelle-Dot; oral estradiol products such as Estrace; combined regimens if you still have a uterus include adding a progestogen such as micronized progesterone [Prometrium] or medroxyprogesterone acetate [Provera]). Non-hormonal for hot flashes: low-dose paroxetine (Brisdelle, specifically FDA‑labeled for hot flashes), SNRIs (venlafaxine), or gabapentin. If contraception is needed, combined oral contraceptives or an IUD can also help regulate bleeding and manage symptoms — discuss options with your clinician. Practical next steps Track your periods and symptoms (apps like Clue, Flo, or Apple Health) for several months. Make an appointment with your primary care clinician or gynecologist. Bring your symptom log, ask about tests to rule out other causes, and discuss treatment options suited to your health history. If you have severe bleeding, new pelvic pain, or symptoms that interfere with daily life, seek care promptly. If you want, tell me your age, specific symptoms, and menstrual pattern and I can help you decide what to discuss with your provider and what tests/treatments might be appropriate.
