A goitre is an enlarged thyroid gland.
It may be diffusely enlarged (such as in the case of Graves disease) or have multiple nodules (called a multi-nodular goitre).
A goitre may require surgery if:
- It causes pressure symptoms (such as difficulty swallowing or breathing).
- It is overactive (produces too much thyroid hormone).
- It has suspicious or cancerous nodules.
- It has enlarged down into the chest (retrosternal goitre).
- Is unsightly (for cosmetic purposes).
