Thyroid Symptom Checklist
Thyroid function can only be checked with a blood test. This page does not estimate a "thyroid age". It counts symptoms the NHS lists for underactive and overactive thyroid; many have other causes too.
Before you start
Method : Thyroid Symptom Checklist — a custom points score written by this site. Each answer adds or subtracts the points shown in the Methodology table below.
Validation : Unvalidated. The points have never been tested against any laboratory measurement or health outcome, and the result is not an age.
Review : not reviewed by a qualified clinician. Educational only — not a diagnosis or a medical test.
A lump or swelling in the neck that is growing, or difficulty swallowing or breathing, should be checked by a GP promptly.

Methodology & assumptions
Your score is the sum of the points below. The weights are our own judgement. The old version added made-up years for TSH results, autoimmune status, iodine intake and stress and gave a "thyroid age". Test results need a doctor, so they were removed with the age output.
| Factor | Answer | Points |
|---|---|---|
| Tiredness that doesn't improve with rest | No | 0 |
| Sometimes | +1 | |
| Most days | +2 | |
| Feeling unusually cold or unusually hot | No | 0 |
| Yes, often | +1 | |
| Unexplained weight gain or loss | No | 0 |
| Yes | +2 | |
| Racing or pounding heartbeat at rest | No | 0 |
| Yes | +1 | |
| Swelling at the front of the neck | No | 0 |
| Yes | +2 | |
| Close relative with a thyroid condition | No / don't know | 0 |
| Yes | +1 |
Worked examples
Tired most days, often cold or hot, unexplained weight change, racing heartbeat, neck swelling, family history: 2 + 1 + 2 + 1 + 2 + 1 = +9 points.
None of these symptoms, no family history: 0 points.
Understanding your result
This counts symptoms you reported. It is not a thyroid test and not an age; the same symptoms can have non-thyroid causes. Health-agency guidance linked below is general and based on populations, not on this score.
