women's health, a ten-place cohort
You are not imagining that something isn't right.
You have persistent symptoms.
You have tried the obvious.
You have been told it is normal, or to wait.
The Answer is my reading of your body as a whole.

The AnswerAbout ten days later, you get my written reading of what is most likely going on, and why. We talk it through on a 30-minute call, online or in person in London.
The first changeOne thing to try first. I tell you why, and what you should notice by when if I'm right.
Eight weeks laterI check in at weeks 2, 4 and 8. At week 8 we check The Answer: right, wrong, or still open.

what you've heard about your symptoms
Everyone and everything has a theory.
an example answer
Read a simplified example.
Every Answer is one of four: I know what this is / I have a strong hypothesis / These are the two most likely explanations / I don't know yet, and here is what we need to find out.
A 29-year-old woman. No period, but her tests came back “normal”.
- What I know
- No period for seven months. Negative pregnancy test. Standard blood and hormone tests came back in range. Marathon training six days a week. Lost 5 kg without trying. Often cold.
- What I think, and why it fits
- Her system is most likely running on empty. More energy is going out than coming in, so her brain has turned down the signal to her ovaries. “Normal” does not rule this out: in this pattern LH and FSH often sit at the low end of the range and oestrogen is low, which is easy to miss on one test with no cycle to compare against. Normal prolactin and thyroid make the other common causes less likely. The timing fits too: her period stopped when training stepped up, and the weight loss and feeling cold follow the same pattern.
- What is still open
- The actual numbers, not just “normal”. Where her LH, FSH and oestrogen sit within the range would support or weaken this reading. PMOS is less likely, with no history of long cycles or spots.
- What happens next
- Seven months without a period should be assessed by her GP now. Her plan asks for the actual values and raises bone health, because a bone density scan is usually considered after six months without a period. It asks about her eating patterns first and flags the weight she lost without trying. Then more fuel and less training.
- What I expect by week 8
- She feels warmer and less tired, and her weight is steady or rising. Her period may take longer to return. If nothing has changed by week 8, the reading changes.

questions women ask
The ones women ask first.
When does it start?
Intakes open on 9 December. Your Answer arrives about ten days after your intake.
Is it a diagnosis?
No. It's a reasoned Answer with the working shown. Your Body File includes a section for your GP, setting out your history, what the Answer found, and the questions to ask. Diagnosis, and any tests, stay with your GP. You arrive knowing what to ask, and why.
Is it AI?
I read every file and write every Answer. Software keeps your story organised. That's its job.
Why a nutritionist?
Most of what you describe sits where food, energy, sleep and your cycle meet. That is my training. I read your symptoms, history and past results together, which a ten-minute GP appointment can't. I don't diagnose or prescribe. Where something needs a doctor, the section for your GP says what to ask for and why.
Can I get a refund?
If you decide The Answer isn't right for you, tell me during your results call. If you feel you have gained no useful understanding of your health or what to do next, I will refund your £250. You do not need to prove your case or justify your decision. For a refund or cancellation, email me at contact@luisahowell.com.
Who isn't this for?
Anyone under 18. Anyone who might be pregnant: take a test first. Anyone with very heavy bleeding, severe pain, bleeding after sex or blood in their poo: see your GP first.
Why not just see my own GP?
You should. Then go back with this. A GP appointment is about ten minutes, and your story takes longer than that. I do the long read so your ten minutes count.
Why not ask ChatGPT?
It can list the causes of a missing period. It can't ask you the next question, notice what you left out, or check back at week 8 to see if it was right.
Can I get blood tests on the NHS?
Your GP decides which tests, if any, to order. The GP section of your Body File sets out which ones to ask about, and on which day of your cycle, so the question is clear first time.
Is it only about periods?
No. Sleep, skin, digestive issues and energy are read together with your cycle, because the body does not work in silos.
Can you help with stomach issues?
Yes, especially when they follow your cycle. I look at timing, food, stress and sleep together, and set out which tests to ask about first.
I'm on the pill, or just came off it.
On the combined pill, the monthly bleed is a withdrawal bleed, not a period, so it can hide what's happening underneath. If you've stopped and your period hasn't come back, this is exactly what The Answer is for.
I already have a PMOS or PCOS diagnosis.
Then you have a name (PMOS is what PCOS is now called). The Answer looks at what's driving yours, what's worth trying first, and how you'll know if it's working.
Who are the network?
Professionals I know and trust. If you need one, your Answer says so and I introduce you. Their fees are separate.
What if you find something serious?
If anything you tell me needs a doctor soon, I say so straight away. I don't wait for your Answer.
Who sees my information?
Only me. It's never sold, and never shared with advertisers.
Why not a blood test membership for the same money?
A blood test gives you numbers. It doesn't know that your period went when the marathon training started, or that you've been cold since March. I start with your story, then tell you which numbers matter and why, so the tests you do get are the right ones. Which tests, if any, is your GP's decision.
