Find your symptom.
Symptoms rarely arrive alone, and most have more than one possible cause. Type what you're feeling in your own words — each page explains what the symptom is, which hormones are commonly evaluated, what else can contribute, and what to do next.

One symptom, several possible explanations.
Hormones don't work in isolation. Estrogen, progesterone, testosterone, DHEA, cortisol and thyroid hormone all influence sleep, mood, temperature, metabolism and tissue health — so a single complaint like fatigue can point in several directions at once.
Life stage matters too. The same symptom means something different in perimenopause than it does five years after your final period, and conditions such as PCOS or thyroid disease can produce an almost identical picture. That's why every page here describes possibilities rather than verdicts, and why testing comes before treatment.

Explore the hormone guidesFour patterns behind most symptoms.
Recognizing the cluster you're in is the fastest way to know what's worth testing.
Estrogen & progesterone
Temperature and sleep unravel first
Hot flashes, night sweats and 3 a.m. waking often trace back to fluctuating estradiol and falling progesterone — though stress physiology and alcohol shape them too.
Progesterone & cortisol
Mood, calm and focus slip
Anxiety that arrives without a reason, a short fuse and word-finding pauses are commonly evaluated alongside progesterone, cortisol rhythm and thyroid function.
Insulin, cortisol & thyroid
Body composition changes
Midlife studies show fat shifting toward the abdomen and lean mass declining, partly independent of weight change — a metabolic picture, not a willpower one.
Testosterone, estrogen & DHEA
Drive, strength and intimacy fade
Low libido, thinning muscle and dryness are physiology. Testosterone, local estrogen and DHEA are usually part of the evaluation — as are sleep, medications and relationships.

The four symptoms women ask about most, each written as a full education page.
Hot flashes
Sudden waves of heat through the chest, neck, and face — most often driven by falling estradiol destabilizing the brain's thermostat.
Learn More Temperature & sleepInsomnia & broken sleep
Falling asleep is easy, staying asleep is not. Low progesterone is the classic driver of the 2–3 AM wake-up.
Learn More Mood & brainBrain fog & memory lapses
Losing words mid-sentence and walking into rooms blank. Estrogen is a major regulator of brain glucose use and acetylcholine.
Learn More Body & metabolismWeight gain & belly fat
Same diet, new shape. Falling estradiol shifts fat storage to the abdomen and drives insulin resistance.
Learn MoreBrowse the way symptoms actually cluster.
Temperature regulation
Flushing, sweating and feeling wildly out of step with the room around you.
Sleep
Falling asleep is rarely the problem — staying asleep usually is.
Mood
Anxiety, irritability and low mood that arrive without an obvious reason.
Cognitive
Word-finding pauses, lost names, and the sense that focus takes effort now.
Energy
Tiredness that sleep doesn't fix, and motivation that used to be automatic.
Weight & metabolism
Body composition and appetite shifting without a change in habits.
Skin & hair
Collagen, oil production and hair cycling all respond to hormones.
Intimacy
Desire, comfort and tissue health are physiology — not willpower.
Bones, joints & heart
The quiet changes that matter most for the next thirty years.
Cycle & fertility
Cycle length, flow and fertility often change years before periods stop.

33 symptoms
Hot flashes
Sudden waves of heat through the chest, neck, and face — most often driven by falling estradiol destabilizing the brain's thermostat.
Learn More Temperature & sleepNight sweats
Hot flashes that arrive during sleep, soaking sheets and fragmenting rest — usually low estradiol paired with low progesterone.
Learn More Temperature & sleepInsomnia & broken sleep
Falling asleep is easy, staying asleep is not. Low progesterone is the classic driver of the 2–3 AM wake-up.
Learn More Body & metabolismFatigue & low energy
Bone-deep tiredness that sleep doesn't fix — usually a stack of low hormones, thyroid drift, and depleted iron, B12, or vitamin D.
Learn More Mood & brainBrain fog & memory lapses
Losing words mid-sentence and walking into rooms blank. Estrogen is a major regulator of brain glucose use and acetylcholine.
Learn More Mood & brainAnxiety & panic
New or worsening anxiety in your 40s is frequently hormonal — progesterone withdrawal removes the brain's natural calming signal.
Learn More Mood & brainMood swings & irritability
Up one minute, flattened the next. Estradiol drives serotonin; progesterone steadies the response.
Learn More Mood & brainLow mood & depression
A flat, joyless baseline that arrives with the hormone transition — a documented window of increased depression risk.
Learn More Body & metabolismWeight gain & belly fat
Same diet, new shape. Falling estradiol shifts fat storage to the abdomen and drives insulin resistance.
Learn More Body & metabolismBloating & digestive changes
New bloating in midlife often traces to estrogen–progesterone imbalance and shifts in gut motility and the estrobolome.
Learn More Intimacy & urinaryLow libido
Desire that disappeared. Testosterone is the most under-tested hormone in women — and often the missing piece.
Learn More Intimacy & urinaryVaginal dryness & painful sex
Thinning, dryness, and pain caused by loss of local estrogen — one of the few menopause symptoms that worsens without treatment.
Learn More Intimacy & urinaryUrinary urgency & recurrent UTIs
The bladder and urethra are estrogen-dependent too. Loss of estradiol drives urgency, leaking, and repeat infections.
Learn More Skin, hair & appearanceHair thinning & loss
Widening part and less volume — falling estrogen leaves androgens relatively dominant at the follicle, often on top of low ferritin.
Learn More Skin, hair & appearanceDry, crepey skin & new wrinkles
Women lose roughly 30% of skin collagen in the first five years after menopause. Estrogen is the reason.
Learn More Heart, bone & jointsJoint pain & stiffness
Waking stiff at 47 is not just aging. Estrogen is anti-inflammatory and directly supports cartilage and tendon.
Learn More Heart, bone & jointsHeart palpitations
Fluttering or pounding — often hormonal, but always worth a cardiac evaluation first.
Learn More Heart, bone & jointsBone loss, osteopenia & osteoporosis
Women can lose up to 20% of bone density in the five to seven years after menopause. It's silent until it isn't.
Learn More Cycle & fertilityIrregular or heavy periods
Cycles that shorten, skip, or flood are the defining sign of perimenopause — usually estrogen high relative to progesterone.
Learn More Cycle & fertilityBreast tenderness & swelling
Tender, heavy, or lumpy breasts most often reflect estrogen high relative to progesterone.
Learn More Cycle & fertilityTrouble conceiving after 35
Declining egg quality plus low progesterone and nutrient gaps — much of which is measurable and modifiable.
Learn More Body & metabolismMuscle loss & weakness
Losing strength and definition despite the same workouts — estrogen and testosterone both protect muscle.
Learn More Mood & brainDizziness & vertigo
Lightheadedness or spinning that arrives with the hormone transition — estrogen affects the inner ear and blood-pressure regulation.
Learn More Mood & brainHeadaches & hormonal migraines
Migraines that worsen or start in perimenopause are usually triggered by estradiol withdrawal, not by a high level.
Learn More Skin, hair & appearanceItchy skin & crawling sensations
Itching, prickling, or a crawling sensation under the skin — an under-discussed effect of estrogen loss on skin and nerves.
Learn More Skin, hair & appearanceVoice changes & hoarseness
A deeper, rougher, or more easily tired voice — the vocal folds are hormone-responsive tissue.
Learn More Skin, hair & appearanceDry eyes & dry mouth
Every mucous membrane is estrogen-dependent — including your eyes and mouth.
Learn More Mood & brainElectric shock sensations & tingling
Brief zaps under the skin, often right before a hot flash — thought to reflect estrogen's role in nerve conduction.
Learn More Skin, hair & appearanceBurning mouth & taste changes
A scalded, burning feeling in the tongue or lips with no visible cause — most common in postmenopausal women.
Learn More Skin, hair & appearanceBody odor changes
A new or stronger scent that your usual deodorant no longer handles — sweat composition changes with hormones.
Learn More Skin, hair & appearanceGum sensitivity & dental changes
Bleeding or receding gums and new sensitivity — the jaw and gums lose estrogen support like the rest of the skeleton.
Learn More Temperature & sleepFeeling cold or temperature intolerance
Not everyone runs hot. Chills, cold hands, and temperature swings often point to thyroid, iron, or blood flow.
Learn More Skin, hair & appearanceAdult & hormonal acne
Deep breakouts along the jaw and chin in your 40s — relative androgen excess as estrogen falls.
