Graves' disease is an autoimmune condition which causes hyperthyroidism. Autoantibodies against the thyroid gland are present. This may be antithyroid peroxidase antibodies or antithyroglobulin antibodies (neither are specific as they may also found in Hashimotos) or TSH receptor antibody (specific)

- eye disease (see revision battle 29.2 to recap which features are Graves' disease specific)
- pretibial myxoedema - only found in Graves
- thyroid acropachy = clubbing, painful toe and finger swelling - also only in Graves
- diffuse thyroid enlargement
