Enlarged Thyroid Gland (goiter) – Causes, Diagnosis, and Treatment

Enlarged Thyroid Gland (Goiter) – Causes, Diagnosis, and Treatment at Emirates Hospitals Group

The thyroid gland plays a crucial role in regulating metabolism, energy production, and overall bodily functions. An enlarged thyroid gland, commonly referred to as a goiter, can develop due to various underlying health conditions. While some cases may be harmless, others require medical intervention to prevent complications.

Causes of an Enlarged Thyroid Gland (Goiter)

Goiter can occur due to multiple reasons, including:

1. Iodine Deficiency: The most common cause worldwide, a lack of iodine in the diet leads to thyroid enlargement as the gland attempts to produce enough hormones.
2. Hyperthyroidism: Conditions like Graves’ disease cause the thyroid to become overactive, leading to swelling.
3. Hypothyroidism: Inadequate thyroid hormone production, often due to Hashimoto’s thyroiditis, can cause the gland to enlarge.
4. Thyroid Nodules: Benign or malignant lumps in the thyroid can lead to noticeable swelling.
5. Pregnancy: Hormonal changes during pregnancy may trigger a temporary goiter.
6. Thyroid Cancer: Though rare, cancerous growths in the thyroid can result in significant enlargement.

Diagnosis of Goiter 

At Emirates Hospitals Group, diagnosing a goiter involves a thorough assessment through:

• Physical Examination: Doctors check for swelling and tenderness in the neck.
• Blood Tests: Thyroid function tests (TSH, T3, and T4) help evaluate hormone levels.
• Ultrasound: Imaging provides a clear view of thyroid size and detects nodules or cysts.
• Fine Needle Aspiration Biopsy (FNAB): A minimally invasive test that determines if nodules are benign or cancerous.
• Radioactive Iodine Scan: This test helps assess how the thyroid is functioning.

Treatment Options for Goiter 

The treatment for goiter depends on its cause and severity:

• Observation: Small, non-symptomatic goiters may require regular monitoring.
• Medication: Hormonal therapy for hypothyroidism, antithyroid drugs for hyperthyroidism, or iodine supplements if deficiency is the cause.
• Radioactive Iodine Therapy: Used to shrink an overactive thyroid gland.
• Surgery (Thyroidectomy): Recommended for large goiters, cancerous growths, or breathing difficulties.
