What is hyperthyroidism?
When the thyroid produces too much hormone, symptoms can include palpitations, heat intolerance, tremor, anxiety or weight loss. Symptoms differ between individuals.
Why examination and blood tests matter
A clinician assesses symptoms and blood tests to investigate the cause. Treatment depends on the cause and the person's circumstances. Medication names in an illustration do not determine the right treatment for a reader.
The role of family and caregivers
Keep a record of prescribed medication times and follow-up appointments. Avoid iodine supplements or treatment changes without advice. Severe illness with fever, a very rapid heartbeat or altered consciousness needs urgent care.
