Causes
Natural menopause reflects the ovaries' gradual decline in hormone production with age. Menopause can also occur earlier for other reasons:- Surgical menopause: Removal of both ovaries causes immediate menopause, often with more abrupt symptoms.
- Cancer treatment: Chemotherapy and pelvic radiation can damage the ovaries.
- Primary ovarian insufficiency: In a small number of women, ovarian function declines before age 40, which deserves its own medical evaluation.
Symptoms
Every woman's experience is different; symptoms may last a few years or considerably longer:- Irregular periods: Cycles that shorten, lengthen, or skip are usually the first sign of perimenopause.
- Hot flashes and night sweats: Sudden waves of heat and flushing, sometimes drenching at night - the most common symptom of the transition.
- Sleep problems: Trouble falling or staying asleep, often worsened by night sweats.
- Mood and memory changes: Irritability, anxiety, low mood, and "brain fog" are common and tend to improve after the transition.
- Other physical changes: New joint aches, headaches, brief heart palpitations, thinning hair, drier skin, and weight that shifts toward the abdomen.
- Vaginal and urinary changes: Dryness, discomfort with intimacy, and urinary irritation - known as genitourinary syndrome of menopause - tend to persist without treatment.
Diagnosis
Menopause is usually diagnosed from age and the menstrual pattern alone; hormone testing is rarely required, because hormone levels fluctuate so widely during perimenopause that a single measurement can be misleading. Because thyroid problems can mimic menopausal symptoms, your physician may check thyroid function to rule out hypothyroidism when the picture is unclear, and may check a blood count if periods have been heavy, since iron-deficiency anemia is easy to miss. Two practical points are worth knowing: pregnancy is still possible until periods have stopped for a full year, so contraception is still needed during perimenopause; and any bleeding that occurs after menopause - even light spotting - is never considered normal and should be evaluated promptly, as should unusually heavy or prolonged bleeding during the transition.Treatment
Treatment is tailored to your symptoms, health history, and preferences:- Hormone therapy: Estrogen (such as conjugated estrogens) is the most effective treatment for hot flashes; women who still have a uterus take it with a progestogen such as norethindrone, or as a combined estrogen-bazedoxifene product, to protect the uterine lining. For healthy women under 60 who are within about ten years of menopause, benefits generally outweigh risks - a decision to make individually with your physician.
- Nonhormonal medications: Certain antidepressants, such as low-dose venlafaxine, reduce hot flashes for women who cannot or prefer not to take estrogen.
- Local vaginal estrogen: Low-dose creams, tablets, or rings treat vaginal and urinary symptoms with minimal absorption into the body.
- Vaginal moisturizers and lubricants: Nonhormonal over-the-counter products - moisturizers used on a regular schedule and lubricants used with intimacy - relieve dryness and are a sensible first step for many women.
- Lifestyle measures: Regular exercise, a cool bedroom, layered clothing, limiting alcohol and caffeine, and not smoking all help - worth emphasizing through St. Petersburg's long warm season.
Long-Term Health
After menopause, the loss of estrogen accelerates bone loss - from osteopenia toward osteoporosis - and cardiovascular risk gradually rises, making this an important time to review bone density screening, blood pressure, and cholesterol. Adequate calcium and vitamin D, weight-bearing and resistance exercise, and not smoking protect the skeleton, while staying current with recommended screenings - mammograms, colon cancer testing, and diabetes and lipid checks - matters more after menopause than before it. You do not have to simply endure this transition.

Most women who stop treatment for menopause symptoms do so for a reason that could have been fixed: the wrong form of estrogen, a dose never adjusted, or an alarm about risk that did not apply to them.
Patch or pill, and for how long
Estrogen absorbed through the skin from a patch, gel, or spray bypasses the liver and appears to carry less clot risk than tablets such as conjugated estrogens, which makes it the usual choice for women with migraine, higher weight, or elevated triglycerides. The starting dose is low and raised only if hot flashes persist after a few weeks. There is no fixed stop date: the decision is revisited each year, and women doing well past 60 can often continue at the lowest effective dose. A progestogen such as norethindrone, or the combined bazedoxifene-conjugated estrogens product, remains necessary whenever the uterus is present. Our hormone therapy risks and benefits article works through the evidence.
When estrogen is off the table
A history of breast cancer, a prior clot or stroke, active liver disease, or unexplained bleeding rules out systemic hormones. Low-dose paroxetine is the one antidepressant approved specifically for hot flashes, venlafaxine works comparably, and gabapentin at bedtime helps when night sweats are the main problem. Fezolinetant, a newer nonhormonal tablet acting on the brain's temperature center, is an option when those fail, with liver tests checked in the first months.
Sleep and mood are treated on their own terms
Night sweats explain some broken sleep but not all of it. Insomnia that persists once hot flashes are controlled responds to cognitive behavioral therapy, described in our CBT-I article, and obstructive sleep apnea becomes markedly more common after menopause. Low mood that does not lift with better sleep is screened as major depressive disorder rather than assumed to be hormonal.
Hot flashes in a hot climate
Heat, humidity, alcohol, and spicy food are the common triggers, and St. Petersburg supplies the first two most of the year. Moisture-wicking layers, a cooled bedroom, a cold drink at the first sign of a flash, and exercising early in the morning reduce the frequency. Weight that shifts to the abdomen raises cardiovascular risk, which our heart and bone health after menopause guide addresses, and our perimenopause guide covers the years before periods stop.
Bleeding, bones, and the symptoms that stay
Heavy perimenopausal bleeding responds to tranexamic acid taken during the period or to a hormonal IUD, which also serves as contraception. A bone density scan is due at 65, or earlier with risk factors, since bone loss is fastest in the first years after menopause; the osteoporosis page covers treatment. Vaginal dryness and urinary symptoms do not fade the way hot flashes do, and the genitourinary syndrome of menopause page explains why local estrogen is safe for almost everyone. Our endocrine team manages hormone therapy. The National Institute on Aging and MedlinePlus publish patient guidance on symptoms and treatment.
