Subclinical hyperthyroidism is a milder form of hyperthyroidism characterized by low or undetectable serum TSH level, but with a normal serum free thyroxine level. [32] Although the evidence for doing so is not definitive, treatment of elderly persons having subclinical hyperthyroidism could reduce the number of cases of atrial fibrillation ...
In the US, hypothyroidism and hyperthyroidism were respectively found in 4.6 and 1.3% of the >12y old population (2002). [3] In some types, such as subacute thyroiditis or postpartum thyroiditis, symptoms may go away after a few months and laboratory tests may return to normal. [4] However most types of thyroid disease do not resolve on their own.
[vague] [13] [14] Individuals are at higher risk of thyroid storm if their hyperthyroidism is incompletely treated or if their anti-thyroid drugs are discontinued. Many of these individuals have underlying primary causes of hyperthyroidism (Graves' disease, toxic multi-nodular goiter, solitary toxic adenoma, or amiodarone). However, thyroid ...
Both NTIS and primary hypothyroidism may have reduced fT3 and fT4, and elevated TSH (which is common in the hospital, during the recovery phase of NTIS). [2] Prescribing thyroxine to treat this may lead to lifelong thyroid overtreatment. [2] Hyperthyroidism may be assumed due to decreased TSH and a transient fT4 increase.
Some do so only a few months after treatment while others may not be affected for 20–30 years. Hypothyroidism patients must begin a lifelong regimen of thyroid replacement hormones. While the onset of hypothyroidism is most common with radio-iodine treatment, the condition has been observed in patients treated with medication series and surgery.
The most common type of hyperthyroidism, Graves' disease, may additionally cause eye problems (Graves' ophthalmopathy) and skin changes of the legs (pretibial myxedema). [6] Thyroid disease may also cause muscle weakness in the form of thyrotoxic myopathy, but this is constant rather than episodic. [5]
Hyperthyroidism (an example is Graves' disease) is the clinical syndrome caused by an excess of circulating free thyroxine, free triiodothyronine, or both. It is a common disorder that affects approximately 2% of women and 0.2% of men. Thyrotoxicosis is often used interchangeably with hyperthyroidism, but there are subtle differences.
The term is sometimes used to refer to hyperthyroidism, but hyperthyroidism is a more general term. [2] When the level of thyroxine (T4) in the blood exceeds normal range, it can lead to symptoms such as irritability and unexplained weight loss. [3] Types include: Familial dysalbuminemic hyperthyroxinemia; Familial euthyroid hyperthyroxinemia
