Start my hormone assessment
Which of these sound like you?
Perimenopause and menopause show up in a dozen quiet ways. If a few of these feel familiar, a two-minute assessment is the place to start.
What perimenopause and menopause actually feel like.
As estrogen and progesterone shift, symptoms can start in your forties, sometimes earlier, years before periods stop. They're easy to dismiss or attribute to stress, which is why a diagnosis is built on your symptoms and bloodwork with a clinician's review, never a guess.
Hot flashes and night sweats
Sudden heat, flushing, and sweating that disrupt your day and wake you at night.
Sleep that won't hold
Trouble falling or staying asleep, and waking unrested even after a full night.
Mood and anxiety
Irritability, low mood, or a new edge of anxiety that doesn't feel like you.
Brain fog
Trouble concentrating, word-finding lapses, and a duller sense of recall.
Low libido and dryness
A drop in desire, and vaginal dryness or discomfort that affects intimacy.
Aches and body changes
Joint aches, slower recovery, and shifts in weight and body composition.
A licensed clinician confirms what's driving your symptoms with the right testing before recommending treatment. If something else fits better, they'll tell you, and help you find the right path.

Your hormones, replaced and balanced.
Replace what's declining
As estrogen and progesterone fall through perimenopause and menopause, symptoms follow. When your symptoms and labs point to it, a clinician restores those hormones with bioidentical forms your body recognizes, dosed to how you want to feel.
Keep it balanced
Hormones work together. If you have a uterus, your provider pairs estrogen with progesterone to protect the uterine lining, rather than using estrogen alone, so one part of the picture isn't supported at the expense of another.
Add support when labs show it
Some women benefit from low-dose testosterone for libido and energy, DHEA, or localized vaginal estrogen for dryness. A licensed clinician adds these only when your symptoms and bloodwork make the case.
Hormones a provider may consider for you.
Estradiol
Replaces the estrogen your body makes less of, easing hot flashes, night sweats, and dryness.
Progesterone
Bioidentical progesterone for cycle balance, sleep, and protecting the uterine lining.
Testosterone (for women)
Low-dose testosterone to support libido, energy, and mood when a clinician finds it appropriate.
DHEA
A precursor hormone that can support energy, libido, and overall hormone balance.
Vaginal Estrogen
Localized estrogen for dryness, discomfort, and intimacy without significant systemic exposure.
Estriol
A gentler estrogen often used in compounded blends for menopausal symptom relief.
Which hormones are appropriate, and at what dose, is a clinical decision your provider makes from your symptoms and bloodwork. Some products are compounded, are not FDA-approved, and require a prescription. Individual results vary.

Bioidentical hormone therapy FAQ.
What is bioidentical hormone therapy?
BHRT uses hormones that are structurally identical to the ones your body makes, like estradiol, progesterone, and testosterone, to replace what declines during perimenopause and menopause. A licensed clinician reviews your symptoms and labs to decide whether it's right for you and to build a personalized plan.
What's the difference between bioidentical and synthetic hormones?
Bioidentical hormones match the molecular structure of the hormones your body produces, while older synthetic versions differ slightly. Your KAYU clinician selects FDA-approved bioidentical options where appropriate and, when a compounded formula fits your needs, explains what that means before anything is prescribed.
What symptoms can BHRT help with?
Many women come to BHRT for hot flashes, night sweats, low energy, mood changes, poor sleep, low libido, brain fog, and vaginal dryness. These symptoms often trace back to shifting hormones, which is why a clinician evaluates the whole picture before recommending treatment. Individual results vary.
What's the difference between perimenopause and menopause?
Perimenopause is the transition leading up to menopause, when hormones fluctuate and symptoms often begin. It can start years before periods stop. Menopause is reached once you've gone 12 months without a period. KAYU clinicians treat women across both stages and tailor care to where you are.
Do I need bloodwork before starting?
In most cases, yes. A licensed clinician reviews relevant hormone and health markers alongside your symptoms to confirm what's driving how you feel and to choose a safe, personalized protocol, then monitors you over time and adjusts as needed.
Is BHRT safe, and what about breast cancer or clot risk?
A licensed clinician reviews your health history and labs before anything is prescribed, and declines or adjusts treatment if it isn't appropriate for you. Hormone therapy has both benefits and risks, including considerations around breast cancer and blood clots that depend on your history, the hormones used, and how they're delivered. Your provider reviews these with you, and ongoing monitoring is part of staying safe.
How quickly will I notice a difference?
Many women notice relief from hot flashes, sleep issues, and mood within a few weeks, with fuller benefits building over the following months as your provider fine-tunes your protocol. Everyone's timeline is different, which is why follow-up and monitoring are part of care. Individual results vary.
Can I do this online, and do you take insurance or HSA / FSA?
Yes. Your assessment, video consult, and follow-ups happen online, and medication ships to your door, with bloodwork through an at-home kit or a nearby lab. You pay for your provider and care; if medication is prescribed, the pharmacy bills it separately at cost. No insurance is required, and many patients use HSA or FSA funds toward eligible care.
Who's a candidate, and can I cancel anytime?
Women experiencing perimenopausal or menopausal symptoms are common candidates, but it isn't right for everyone. A licensed clinician reviews your symptoms, labs, and health history, including any conditions that affect hormone therapy, to determine whether BHRT or another path is the better fit. There's no long-term commitment, and you can cancel anytime.
