What is the difference between thyrotoxicosis and hyperthyroidism?

Is thyrotoxicosis an emergency?
Background. Thyroid storm is a rare clinical picture seen in severe thyrotoxicosis. The condition is a critical emergency presentation occurring in 1-2% of hyperthyroid patients, with treated mortality rates reported between 10-30%.
How serious is thyrotoxicosis?
Untreated, thyrotoxicosis can lead to serious medical complications such as heart rhythm disturbances and Osteoporosis, caused from the long-term effects of hormone overproduction.
What triggers thyrotoxicosis?
In thyrotoxicosis, thyroid hormone levels are elevated with or without increased thyroid hormone synthesis. The most common forms of thyrotoxicosis are caused by excess intake of the thyroid hormone medication levothyroxine or result from a temporary excess release of thyroid hormone due to subacute thyroiditis.
What are the signs of thyrotoxicosis?
Symptoms of overt thyrotoxicosis include heat intolerance, palpitations, anxiety, fatigue, weight loss, muscle weakness, and, in women, irregular menses. Clinical findings may include tremor, tachycardia, lid lag, and warm moist skin.
How long does thyrotoxicosis last?
The thyrotoxic phase lasts for 1-3 months and is associated with symptoms including anxiety, insomnia, palpitations (fast heart rate), fatigue, weight loss, and irritability. The hypothyroid phase typically occurs 1-3 months after the thyrotoxic phase and may last up to 9 – 12 months.
What is the treatment of thyrotoxicosis?
