Women's hormone conditions, explained without jargon
Plain-English explainers on the conditions we test for most often. Each page lists symptoms, the biomarkers that identify it, and what changes when you actually know what's driving things.
Perimenopause
The 4–10 year hormonal transition before menopause — usually starts in the late 30s or 40s.
Read explainer →Menopause
Defined as 12 consecutive months without a period — the start of the postmenopausal chapter.
Read explainer →PCOS (Polycystic Ovary Syndrome)
The most common hormonal condition in women — driven mostly by insulin resistance, not by 'cysts'.
Read explainer →Hypothyroidism
An under-active thyroid — far more common in women, and routinely missed.
Read explainer →Hyperthyroidism
An over-active thyroid — less common than hypothyroidism but more urgent.
Read explainer →Low Progesterone (Luteal-phase deficiency)
The first hormone to fall in perimenopause — and a common cause of PMS and short cycles.
Read explainer →Ovarian Reserve & Fertility
How many eggs you have left — and what that means for your timeline.
Read explainer →Estrogen Dominance
An imbalance — usually too little progesterone for the estrogen present — rather than truly 'high' estrogen.
Read explainer →Hormonal Acne
Adult, cyclical acne along the jawline — almost always driven by androgens and insulin.
Read explainer →Insulin Resistance in Women
The metabolic engine behind PCOS, perimenopausal weight gain, brain fog and stubborn cravings.
Read explainer →Adrenal Stress & Cortisol in Women
HPA-axis dysregulation — the 'wired but tired' picture that overlaps perimenopause and thyroid disease.
Read explainer →PMDD & Severe PMS
Premenstrual dysphoric disorder — the severe end of PMS, driven by an abnormal brain response to normal hormone shifts.
Read explainer →Hair Loss in Women & Hormones
Diffuse thinning, a widening part or a shrinking ponytail — usually thyroid, ferritin or androgens behind it.
Read explainer →Endometriosis
A common, under-diagnosed inflammatory condition — endometrial-like tissue growing outside the uterus.
Read explainer →Symptoms but no diagnosis?
Our health specialists helps you map your symptoms to the right panel — and reads the results in the context of your life, not a lab handbook.
