Everything we know, written for you.

Ten symptom pages grouped under the five systems we test. Find the one that sounds like your life.

• No. 01

  Struggling with everything.

  When everything is off — sleep, mood, energy, gut, periods — it's almost never one diagnosis.

  →
• No. 02

  My period destroys me.

  Heavy bleeding and brutal PMS aren't normal. They're hormone signal. What we look for.

  →
• No. 03

  I'm constantly exhausted.

  Fatigue with normal-looking bloods is almost always thyroid, ferritin or cortisol. Often two of three.

  →
• No. 04

  My gut is slow and bloated.

  Restriction diets manage symptoms; they don't treat causes. Where the actual driver usually lives.

  →
• No. 05

  I can't shift the weight.

  After 35, body composition responds to insulin and cortisol — not willpower. What we test first.

  →
• No. 06

  I'm anxious about everything.

  3am wake-ups, ‘wired but tired’, cortisol face. Anxiety with no trigger is biochemistry.

  →
• No. 07

  I'm ashamed of my skin.

  The surface is the symptom. Adult acne at 35 is almost always androgens, gut or oestrogen clearance.

  →
• No. 08

  I don't feel like myself after 40.

  Perimenopause can begin a decade before your final period. Progesterone falls first, then everything moves.

  →
• No. 09

  My immune system feels broken.

  A Hashimoto's diagnosis without a plan is the norm. The functional approach to thyroid antibodies.

  →
• No. 10

  I'm losing my hair and my drive.

  Hair, ferritin, thyroid, hormones, cortisol. Same root causes drive shedding and lost drive.
