Why Treat Hyperthyroidism?
Excess thyroid hormone puts stress on:
Timely treatment restores the body's balance and protects long-term health.
Treatment Option 1: Medication (First Line for Most Children)
The primary medication is methimazole (MMI).
Why MMI is preferred:
Carbimazole is used in some countries but converts to methimazole in the body.
What Parents Can Expect
MMI does not cure Graves' disease immediately — instead, it controls the hormone levels while the immune system gradually settles.
Possible Side Effects (Rare but Important)
- Extremely rare (1 in 1,000)
- Symptoms: fever, sore throat → stop medication → seek urgent care
Routine blood tests help ensure safety.
Treatment Option 2: Radioactive Iodine (RAI)
Used rarely in younger children but considered in:
RAI works by shrinking the thyroid and reducing hormone production.
Most children eventually become hypothyroid — which is easy to treat with daily levothyroxine.
Treatment Option 3: Surgery
Thyroidectomy may be recommended if:
Performed by an experienced surgeon, surgery is safe and definitive.
Children will need lifelong levothyroxine afterwards.
