Thyroid disease

Hypothyroidism

  • Overt hypothyroidism occurs in 1–5% of young people with type 1 diabetes
  • Compensated hypothyroidism — asymptomatic, normal thyroxine level, modestly raised thyroid-stimulating hormone (TSH) — occurs in 1–10%

Diagnostic pointers

  • Goiter
  • Increased weight gain (facial fullness)
  • Decreased growth rate
  • Tiredness, lethargy

Hypothyroidism may not significantly affect metabolic control
