If you’re in your 40s or early 50s and your sleep, mood, periods or body temperature have stopped behaving, changing hormones are a likely reason. Perimenopause can start years before your last period, and many women go a long time without a clear answer. Here’s how to tell what’s going on, what labs can and can’t show, and when hormone therapy is worth a conversation with a provider.
The Stages
What Stage Are You In?
Perimenopause
The transition before menopause. Estrogen and progesterone rise and fall unevenly. Often starts in your 40s and can last several years.
Menopause
12 months in a row without a period. In the U.S., the average age is 51.
Postmenopause
Everything after that. Some symptoms ease; bone and heart health matter more.
Symptoms
What It Can Feel Like.
- Hot flashes and night sweats
- Trouble falling or staying asleep
- Periods closer together, further apart, heavier or lighter
- Mood changes, anxiety or irritability
- Brain fog and trouble focusing
- Vaginal dryness or pain during sex
- Lower sex drive
- Weight shifting to the midsection
You may have a few of these or most of them. Many also overlap with thyroid problems, low iron and other conditions, which is where labs come in.
Labs
What Labs Can and Can’t Tell You.
During perimenopause, hormone levels can swing from one day to the next, so a single blood test can’t confirm or rule it out. A diagnosis is based mostly on your age, symptoms and cycle history. Labs still matter: they rule out other causes like a thyroid problem or anemia, set a baseline before treatment, and help check that treatment is safe for you.
Labs, made simple
Your provider orders your labs, and you get them drawn at a lab location near you.
What’s Changed
Hormone Therapy, Revisited.
For about two decades, many women were told hormone therapy was too risky, largely because of how early Women’s Health Initiative results were reported. The Menopause Society’s position today: for most healthy women with symptoms who are under 60 or within 10 years of menopause, the benefits outweigh the risks.

Is It Right for You?
When Hormone Therapy Makes Sense.
It’s the most effective treatment for hot flashes and night sweats, and it helps prevent bone loss. It may be a good fit when:
Symptoms affect your life
Hot flashes, night sweats or poor sleep are getting in the way of work, sleep or relationships.
Timing is on your side
You’re under 60, or within 10 years of your last period.
It’s safe for you
No history of breast cancer, blood clots, stroke, heart attack, liver disease or unexplained vaginal bleeding.
Other options
If you still have a uterus, estrogen is paired with progesterone to protect the uterine lining. Not a candidate, or not ready? Non-hormonal prescription options and low-dose vaginal estrogen for dryness are also available. Hormone therapy is prescribed only where clinically appropriate.
