What should you know about enlarged goitre symptoms?

A goitre is an enlarged thyroid gland. It may be visible as a fullness low in the neck, or noticed as a tight collar, throat pressure or a lump that moves when you swallow. Some goitres do not change hormone production. Others occur with an overactive thyroid, which may bring palpitations, tremor, heat intolerance or unexplained weight loss, or an underactive thyroid, which may bring tiredness, feeling cold, dry skin or constipation. A neck swelling is not enough to identify the cause.

Arrange a GP Consultation if the swelling is new, growing, uncomfortable or affecting swallowing. The clinician may examine your neck, ask about voice and breathing changes, and review medicines and family history. A Thyroid Function Test checks hormone signals in the blood and helps guide the next assessment. Do not squeeze the swelling or start thyroid products without medical advice. Note when you first noticed it and whether symptoms change with meals, exertion or lying down.

Seek urgent medical help if neck swelling causes marked difficulty breathing, inability to swallow fluids, rapidly worsening pressure or a sudden voice change. Arrange prompt clinical review for persistent hoarseness, pain, a firm or enlarging area, or swollen neck glands. These features need assessment; they do not by themselves establish a diagnosis.

Ask what might be enlarging the thyroid, whether your hormone levels are high or low, whether further imaging is appropriate, and which changes should prompt earlier review. Ask whether any current medicine or supplement could affect thyroid testing.
