How common is thyrotoxicosis? Thyroid disease tends to be commoner in women than men (up to 10 times more). Thyrotoxicosis can occur at any age and there is a 1 in 100 chance of a woman developing it in her lifetime and a 1 in 1,000 risk for men. The number of new cases diagnosed each year is 3 per 1,000 women.
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 is the most common cause of thyrotoxicosis?
The most common cause of thyrotoxicosis is Graves’ disease, followed by toxic multinodular goiter (TMNG) and toxic adenoma (TA). Other causes include thyroiditis, subacute thyroiditis, painless thyroiditis, and gestational hyperthyroidism.
What percentage of the population has hyperthyroidism?
About 1.2 percent of people in the United States have hyperthyroidism.
Does thyrotoxicosis go away?
Hyperthyroidism typically does not go away on its own. Most people need treatment to make hyperthyroidism go away. After treatment, many people develop hypothyroidism (too little thyroid hormone).
What triggers thyrotoxicosis?
What causes thyrotoxicosis? The main cause of thyrotoxicosis is hyperthyroidism, which is an overactivity of the thyroid gland resulting in it producing excess levels of thyroid hormones. If the hyperthyroidism is due to an autoimmune cause, it is called Graves’ disease.
Is thyrotoxicosis an emergency?
The extreme manifestation of thyrotoxicosis is thyroid storm, which manifests as an acute, severe, life‐threatening hypermetabolic state caused either by excessive release of thyroid hormones, causing adrenergic hyperactivity, or altered peripheral response to thyroid hormone following the presence of one or more …
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.
What are the signs of thyrotoxicosis in hyperthyroidism?
Symptoms and signs of GD are usually due to the underlying hyperthyroidism or immune-mediated cellular infiltration. The most common manifestations are weight loss, fatigue, palpitations, tremor, and goiter.
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.
Why thyroid disorders are more common in females?
The risk for women is about 10 times higher than for men. One reason for this is that thyroid disorders are often triggered by autoimmune responses, which happen when the body’s immune system starts to attack its own cells.
What happens if a goiter is left untreated?
If hypothyroidism is not treated, it can lead to various complications, such as : Goiter: The lack of thyroid hormone causes constant stimulation of the thyroid gland that eventually leads to its enlargement. This is called a goiter. Goiter can cause cosmetic concerns and affect breathing and swallowing.

What is the treatment of thyrotoxicosis?
Generally, thyrotoxicosis should be evaluated and treated by an endocrinologist. Therapy, including radioactive iodine and antithyroid medication, requires careful follow-up, which is best performed by a specialist.
Is hyperthyroidism and thyrotoxicosis the same?
Hyperthyroidism is characterised by increased thyroid hormone synthesis and secretion from the thyroid gland, whereas thyrotoxicosis refers to the clinical syndrome of excess circulating thyroid hormones, irrespective of the source.
How does thyrotoxicosis affect the body?
Hyperthyroidism (overactive thyroid) occurs when your thyroid gland produces too much of the hormone thyroxine. Hyperthyroidism can accelerate your body’s metabolism, causing unintentional weight loss and a rapid or irregular heartbeat.
