The basics

What is the difference between perimenopause and menopause?

Perimenopause is the transition; menopause is the destination. In perimenopause, ovulation becomes less consistent, progesterone falls, and estrogen may remain present without enough progesterone to balance it. Menopause is when periods have stopped for good.

After menopause, estrone becomes the dominant estrogen. That is ordinary biology, not a problem in itself. For many women, the years before the last period are the most difficult, and the symptoms of that stage are easy to overlook.

Dr. McCarthy covers both in his podcast series Menopause Explained and how to recognize the signs.

What women describe

What are the symptoms of perimenopause and menopause?

Symptoms vary widely and often begin in the late thirties or forties. Each of these can have more than one cause, so your physician looks at the whole picture before recommending treatment.

  • Hot flashes and night sweats

    Among the most common symptoms of the transition, and a frequent reason sleep is disrupted.

  • Interrupted sleep

    Night sweats are one cause of broken sleep in midlife. Stress, mood and other health issues can contribute too.

  • Anxiety, irritability and low mood

    Progesterone acts in the brain, and mood changes are sometimes among the first things women notice.

  • Brain fog

    Memory and focus can feel less reliable during these years.

  • Changes in your menstrual cycle

    Heavier, lighter or less predictable periods are common in perimenopause and worth discussing with a physician.

  • Vaginal and urinary symptoms

    Dryness, pain with intimacy, urgency and repeat UTIs can reflect tissue changes after menopause. They are worth raising, not just accepting.

  • Questions about treatment options

    Whether hormone therapy makes sense for you, which hormones and routes exist, and what the research says about safety.

Know what you're taking

Why isn't HRT one thing?

"HRT" describes a category of treatment rather than a single plan. The benefits and risks depend on the details: which hormone, bioidentical or synthetic, by what route, at what dose, and how it is monitored.

Estrogen is a family name. Estradiol, estrone and estriol are different estrogens. A warning about one is not automatically about yours. Read the paper.

Progesterone is not a progestin. Bioidentical progesterone is the molecule your body makes; progestins are synthetic. Progesterone also reaches the brain, acting on the system responsible for calm and sleep. On his podcast, Dr. McCarthy calls it a "simple, humble hormone." One Word, Many Medicines

How the route changes what estradiol does
RouteWhat to know
PillLiver first; some estradiol becomes estrone. Expected, and worth monitoring.
Patch or creamSkips the liver and largely stays estradiol. Creams can transfer to others; patches avoid that.
InjectionThe ester sets the rise and fall, and when labs should be drawn.
PelletSteady for months. Once placed, the dose can be added to but not reduced.
Vaginal (local)Treats the tissue it reaches. Not expected to support bone.

Which route fits you is a conversation. More in Route Matters.

How it works

How does Protea approach menopause treatment?

Menopause care follows the same four steps as all hormone therapy at Protea, adapted to where you are in the transition.

  1. Your first visit

    What has changed, when it started, what you've already tried and what you would like to improve.

  2. Baseline labs

    Lab work before a hormone is prescribed. Hormones fluctuate in perimenopause, but results still give your physician useful information and a point of comparison.

  3. Your hormone, route and dose

    If hormone therapy is appropriate, your physician explains which hormone, which form and how much, and why.

  4. Follow-up

    Repeat labs, timed to how your hormone is given, and adjustments as your needs change.

The 5 questions to ask before starting hormone therapy

From Dr. McCarthy's episode The 5 Questions Every Woman Should Ask. Your physician should be able to answer each one clearly.

  1. What hormone am I taking?
  2. Why am I taking it?
  3. How does it get into my body?
  4. How will we monitor it?
  5. What would make us change the treatment plan?

See what we test on the lab testing page, and why perimenopausal labs do matter.

Safety

Is hormone therapy for menopause safe?

The answer depends on which hormone, by which route, for whom, and how it is monitored. Your physician will go through how the research applies to you.

The 2002 Women's Health Initiative studied one synthetic estrogen derived from horse urine, plus a synthetic partner hormone that is not the progesterone your body makes, both as pills, in women averaging around sixty-three. That combination increased breast cancer risk; the finding was real. A second group, on the estrogen alone, did not show the increase, and the trial found fewer hip fractures. Those details received far less attention.

In November 2025, the FDA announced it would remove the boxed breast cancer warning from menopausal estrogen products, while keeping the uterine lining warning for systemic estrogen taken alone. A label change is not, on its own, a reason to start hormone therapy, and a headline is not a reason to stop. Two Clinics, One Failure explains why these decisions should start from the individual patient.

Real cautions remain. For women with a uterus, systemic estrogen requires protection of the uterine lining. Oral estrogen carries a clotting concern that looks different with other routes. And estradiol is not, by itself, a complete plan for heart or memory health.

Who it's for

Who is menopause hormone therapy for?

Women in perimenopause or after menopause whose symptoms affect daily life, and who want to understand their options before deciding. Symptoms don't always point to hormones, and an evaluation may lead elsewhere, for example to stress, diet or thyroid function.

We're in south Tempe on Elliot Road near I-10, close to Chandler, Ahwatukee and Gilbert.

Talk with us first if

  • You've had a hormone-sensitive cancer. Decisions are made with your oncology team, not around them.
  • You have any bleeding after menopause. It should be evaluated, whatever treatment you use.
  • You have a history of blood clots. Route matters here.
  • You're on hormones from another clinic and something feels off. Don't stop on your own; bring it to us.

Questions

Menopause treatment questions

What is the difference between perimenopause and menopause?

Perimenopause is the transition: ovulation becomes less consistent and progesterone falls, often years before the last period. Menopause is when periods have stopped for good, and estrone becomes the dominant estrogen.

Do I need labs if my hormones fluctuate in perimenopause?

At Protea, yes, before hormones are prescribed. Hormones do fluctuate in perimenopause, but labs still give useful information, and they are how a plan is checked once you start. Repeat testing is timed to how your hormone is given.

Is menopause hormone therapy safe?

The answer depends on which hormone, by which route, for whom, and how it is monitored. The 2002 Women's Health Initiative findings were real for one synthetic estrogen and a synthetic progestin taken as pills, and they were later applied far more broadly than that data supported. Your physician will review your own history and risks with you.

I only have vaginal dryness or repeat UTIs. Do I need full hormone therapy?

Not necessarily. Local vaginal estrogen acts on the tissue where it is placed, and for urinary infections that keep returning after menopause it has trial evidence behind it. It is not expected to support bone, so your physician may still discuss bone health separately.

Can I stop my hormones because of something I read online?

Please do not change anything on your own. Starting, stopping, raising, lowering or switching a hormone are decisions to make with a physician who knows your history. Write the concern down and call your care team; you do not have to wait for your next visit.

Where is Protea, and do you see patients outside Tempe?
