Goitre in Nigeria
Swelling in the neck — what it means and when to worry
A goitre is any enlargement of the thyroid gland. It is visible as a swelling at the front of the neck that moves up with swallowing. In Nigeria, goitre is common — driven by iodine deficiency in inland areas, autoimmune thyroid disease, and thyroid nodules. Most goitres are benign, but any new or growing thyroid swelling must be assessed — thyroid cancer, though rare, must be excluded.
Signs and Symptoms
✓ Visible or palpable swelling at the front of the neck
✓ Swelling moves up when swallowing — distinguishes thyroid from other neck swellings
✓ Feeling of tightness or fullness in the throat
✓ Difficulty swallowing (dysphagia) — if the goitre is large
✓ Difficulty breathing or stridor — from tracheal compression by a large goitre
✓ Symptoms of hypothyroidism or hyperthyroidism if the gland is dysfunctional
✓ A hard, irregular, or rapidly growing lump — must raise suspicion of thyroid cancer
When to Seek Help
Any new neck swellingSee a doctor for assessment — thyroid cancer, though uncommon, must be excluded with imaging and possibly biopsy.
Rapidly growing thyroid swellingUrgent assessment — may represent anaplastic thyroid cancer or thyroid lymphoma — both fast-growing.
Difficulty swallowing or breathingLarge compressive goitre — requires imaging and likely surgical assessment.
Hard, fixed, or irregular thyroid swellingSuspicious for malignancy — urgent ultrasound and fine needle aspiration.
Tests & Diagnosis
🧪 TSH + free T4
Determines thyroid function — is the goitre causing hypothyroidism or hyperthyroidism?
🧪 Thyroid ultrasound
The most important imaging test — assesses goitre size, shows whether it is diffuse or nodular, and characterises nodules for malignancy risk (TIRADS scoring).
🧪 Fine needle aspiration cytology (FNAC)
Biopsy of a thyroid nodule using a thin needle — the definitive test for thyroid cancer. Recommended for nodules above 1 cm with suspicious ultrasound features.
🧪 Anti-TPO and anti-thyroglobulin antibodies
Elevated in Hashimoto's thyroiditis.
🧪 TSH receptor antibodies (TRAb)
Elevated in Graves' disease.
🧪 CT or MRI neck/chest
For large goitres extending into the chest (retrosternal goitre) — guides surgical planning.
Frequently Asked Questions
Can cassava cause goitre?
Yes — cassava contains cyanogenic glycosides (linamarin) that are converted to thiocyanate in the body. Thiocyanate blocks thyroid iodine uptake. Where both iodine deficiency and high cassava consumption co-exist (as in some Nigerian communities), the risk of goitre is particularly high. Ensuring adequate iodine intake mitigates this risk.
Is every neck swelling a goitre?
No — the key distinguishing feature of thyroid swelling is that it moves upward with swallowing. Other neck swellings (lymph nodes, lipoma, branchial cyst, sarotid body tumour) do not move with swallowing. An ultrasound confirms the anatomy.
Is thyroid cancer common in Nigeria?
Thyroid cancer is relatively uncommon in Nigeria compared to Western countries, but incidence is increasing. Papillary thyroid cancer is the most common type — well-differentiated and usually curable. Follicular thyroid cancer is associated with iodine deficiency. All suspicious thyroid nodules must be biopsied.
Can I feel my own thyroid?
A normal thyroid gland is usually not visible or palpable. You can check for goitre by: standing in front of a mirror, tilting your head back slightly, swallowing (take a sip of water), and observing the front of the neck for a bulge below the Adam's apple that rises with swallowing. Any visible swelling should be assessed.
Will my goitre go away?
It depends on the cause. Iodine deficiency goitre reduces with iodine supplementation. Hashimoto's goitre may partially respond to levothyroxine. Graves' goitre improves with treatment. Multinodular goitre (the most common type in older adults) does not resolve without intervention — it may remain stable, grow slowly, or require surgery.
