This isn’t a diagnosis tool. It’s a way to help you see whether your exhaustion, brain fog, and weight changes might be part of a bigger pattern rather than separate, random issues. Read each question carefully, then tap or click your answer.
For each question, choose the answer that feels most like you over the last 3 months. Score yourself honestly. There are no wrong answers here.
Pattern Recognition Assessment

Your Score
Answer the questions above and your pattern will appear here. You can see how many systems are under strain, and what that usually means.
Symptom Cluster Decoder
These three clusters show where fatigue tends to show up in your body. Look for the one where you recognise the most. It’s completely normal to tick boxes in more than one. The goal is to spot which cluster is loudest for you right now.
- Afternoon crash (often 2–4pm)
- Shaky, irritable, or “hangry” if meals are delayed
- Strong cravings for sugar, carbs, or caffeine
- Waking in the night
- Tired, but wired
- Light sleep, vivid dreams
- Waking at night with a busy mind
- Feeling “on edge,” more reactive than you used to be
- Feeling cold when others are fine
- Constipation or sluggish digestion
- Brain fog, slower thinking
- Unexplained weight changes, puffiness, or thinning hair
Decision Map
Look at whichever cluster you identified most with, and start there. If it’s a tie, start with the one that feels most doable for you right now. Progress over perfection, always.
- Include protein at every breakfast
- Avoid long gaps between meals
- Plan a nourishing snack if energy dips mid-afternoon
- Five slow breaths twice a day, or even just deep sighs
- Morning daylight when you can
- Reduce late caffeine if it makes your sleep lighter
- Take a copy of your symptoms to your GP
- Ask what testing makes sense based on symptoms
What to Ask Your Doctor
You deserve to understand what’s going on in your own body. You are not being difficult by asking questions. You are being responsible for your health.
“For the last few weeks / months, I’ve been in bed for 8–10+ hours but waking exhausted most / every morning. I’m also experiencing [brain fog / constipation / feeling cold all the time / extreme tiredness in the afternoons / low mood]. I’d like to understand what could be driving this and what we should investigate.”
“I understand my results are within range, but my symptoms are persisting / getting worse. What would be reasonable to check next based on symptoms?”
Tests you can ask about (your GP decides what’s appropriate) or choose to test privately:
