To identify the false statement about Graves' disease, let's analyze each option:
- Results in hyperthyroidism: Graves' disease causes the thyroid gland to produce too much thyroid hormone, leading to hyperthyroidism. This statement is true.
- Autoimmune disorder: Graves' disease is indeed an autoimmune disorder in which the immune system mistakenly attacks healthy thyroid tissue. This statement is true.
- Common in Male: Graves' disease affects more women than men. Statistically, it is more prevalent in females. Therefore, this statement is false.
- Referred as Toxic diffuse goitre: This is accurate. Graves' disease is characterized by an enlarged thyroid (goitre) and is often referred to as toxic diffuse goitre. This statement is true.
Hence, the false statement is Common in Male.
