DOES THIS SOUND LIKE YOU

You are good at your job.
But something has shifted.

The brain fog.

You lose words mid-sentence. In meetings, on calls, in conversations you have had a hundred times. You used to be sharp. Now you second-guess yourself constantly. You assume it is overwork.

The sleep.

You wake at 3am and cannot get back. Not anxious about anything specific. Just wide awake, sometimes hot, sometimes with a racing heart. You start every day already exhausted.

The GP appointment.

You went. You explained. Bloods came back normal. You were told you are fine. You know you are not fine. So you go back to work and push through.

These are not signs of burnout or ageing. They are recognised symptoms. And there is a pattern underneath them.

WHAT SUMM ACTUALLY DOES

Five questions. Answered plainly.

What does the check do?

15 questions about your symptoms, sleep, energy, and how they relate to stress. It identifies which pattern (perimenopause, thyroid, or burnout) best fits your answers. You get a plain-English result and a GP summary you can download.

What data is stored?

Your answers are stored anonymously. No name, no email, no account required. We store the pattern of answers and the result type only, to improve the tool. If you choose to provide your email, it is stored separately and only used for that purpose.

How is data used?

Anonymised results help us improve the question logic. No data is sold, shared with third parties, or used for advertising. GDPR compliant. Request deletion at any time: hello@summnutrition.co.uk

What do the results look like?

A result type (hormonal pattern, thyroid pattern, or stress pattern), a plain-English explanation, a visual breakdown of your signal scores, and a downloadable one-page GP summary with your full answers and three questions to raise at your appointment.

What do I do with the result?

Download the GP summary and take it to your next appointment. If your result points to thyroid, ask for a full thyroid panel including antibodies. If hormonal, ask about perimenopause assessment. The result links to recommended blood tests and further reading.

WHY IT IS HARD TO DIAGNOSE

Three conditions. Almost identical symptoms.

Clinicians call this the differential diagnosis problem. The same symptoms point in three directions.

PERIMENOPAUSE

Hormonal

  • Hot flushes or night sweats
  • Sleep disrupted by physical symptoms
  • Anxiety without a trigger
  • Cycle changes
  • Brain fog regardless of workload
  • Fatigue that does not improve with rest

Key signal: symptoms persist on holiday

THYROID

Endocrine

  • Fatigue: sluggish, not tired
  • Feeling cold when others are warm
  • Weight gain without dietary change
  • Hair thinning and dry skin
  • Slower cognition and processing
  • Constipation or sluggish digestion

Key signal: feeling cold, not hot

BURNOUT

Stress response

  • Exhaustion tied to workload
  • Sleep disrupted by racing thoughts
  • Anxiety about specific situations
  • Brain fog worse under pressure
  • Better on weekends and holidays
  • No physical symptoms

Key signal: improves with rest

The European Menopause and Andropause Society (EMAS, 2024) recommends broad thyroid screening in perimenopausal women because the symptoms are clinically indistinguishable without investigation.
