Global Burden
- Thyroid disorders are among the most common endocrine diseases worldwide.
- Hypothyroidism prevalence: ~4–10% in Western populations
- Hyperthyroidism is less common (~1–2%) but clinically significant.
- Increasing trends due to: Aging population, Better diagnostic testing, Lifestyle & iodine imbalance
Prevalence in the UAE & the Gulf Region
- Approximately ~5% of the UAE population is affected by thyroid disorders
- Local data shows: Hypothyroidism prevalence ~2–2.5% in tested populations. Higher in women and middle-aged adults
- Thyroid cancer incidence is rising and is now among the top cancers in the UAE
- A significant proportion remains undiagnosed or subclinical
Why It Matters: A Silent Disease
- Up to 60% of patients may be unaware of thyroid dysfunction
- Symptoms are often non-specific and gradual, leading to delayed diagnosis
Clinical Features
Hypothyroidism
- Fatigue, weight gain
- Cold intolerance
- Constipation, depression
- Bradycardia
Hyperthyroidism
- Weight loss, palpitations
- Heat intolerance
- Anxiety, tremors
- Atrial fibrillation (elderly)
Key Investigations
- TSH (most sensitive screening test)
- Free T4 / T3
- Thyroid antibodies (TPO, Tg)
- Ultrasound (nodules/structural disease)
Management Overview
- Hypothyroidism → Levothyroxine replacement
- Hyperthyroidism → Antithyroid drugs, radioactive iodine, or surgery
- Regular monitoring (TSH-guided titration) is essential
Preventable Morbidity & Mortality
Untreated thyroid disease can lead to:
- Cardiovascular disease (HF, arrhythmias)
- Infertility & pregnancy complications
- Neurocognitive impairment
- Myxedema coma/thyroid storm (life-threatening)
Early detection = highly preventable complications
Key Takeaway
Thyroid disorders are common, underdiagnosed, and often silent, yet easily treatable. Routine screening in high-risk groups can significantly reduce avoidable morbidity and mortality.
