Various authors have suggested that thyrotoxic myopathy is a result of the weight loss and generalized asthenia associated with hyperthyroidism. Muscle involvement has been reported to occur in about 80% of thyrotoxic patients (see section #Epidemiology ), [ 7 ] and the most common causes of hyperthyroidism are Graves’ disease , toxic ...
Hyperthyroidism is the condition that occurs due to excessive production of thyroid hormones by the thyroid gland. [3] Thyrotoxicosis is the condition that occurs due to excessive thyroid hormone of any cause and therefore includes hyperthyroidism. [3]
Pretibial myxedema is almost always preceded by the ocular signs found in Graves' disease.

Periodic paralysis is an autosomal dominant myopathy with considerable variation in penetrance, leading to a spectrum of familial phenotypes (only one parent needs to carry the gene mutation to affect the children, but not all family members who share the gene are affected to the same degree).
Levothyroxine is a frequently prescribed drug in the United States, particularly for older people, as lower thyroid function can be associated with aging. Questions remain over how appropriately ...
Thyroid function tests (TFTs) is a collective term for blood tests used to check the function of the thyroid. [1] TFTs may be requested if a patient is thought to suffer from hyperthyroidism (overactive thyroid) or hypothyroidism (underactive thyroid), or to monitor the effectiveness of either thyroid-suppression or hormone replacement therapy.
