Self-check guide
Thyroid Neck Self-Check
A quick mirror check you can do at home to spot swelling or a new bulge in the lower front of your neck — an early, gentle way to stay aware of thyroid changes.
When to see a doctor
- A new swelling or lump that stays in the lower front of your neck
- Trouble swallowing or a feeling of fullness in the throat
- Hoarseness or other voice changes that do not go away
- Neck pressure or pain
- Thyroid-type symptoms that persist (fatigue, weight changes, mood, irregular periods)
This guide is for general education and does not replace professional medical advice. A neck self-check cannot diagnose a thyroid condition — a simple blood test can.

How is this calculated?
This is a visual self-check, not a calculator. A doctor confirms a thyroid lump with examination and a TSH blood test and (if needed) an ultrasound — the guide here helps you spot when to ask for one.
When to talk to a doctor
See a doctor if you notice a visible lump, persistent swelling, hoarseness, swallowing trouble, unexplained weight change, fatigue, or hair changes — especially in pregnancy or postpartum.
