Hypothyroidism is more common in women than in men. [3] People over the age of 60 are more commonly affected. [3] Dogs are also known to develop hypothyroidism, as are cats and horses, albeit more rarely. [13] The word hypothyroidism is from Greek hypo-'reduced', thyreos 'shield', and eidos 'form', where the two latter parts refer to the ...
The secular trends of hypothyroidism reveal how the disease has changed over the course of time given changes in technology and treatment options. Even though ultrasound technology and treatment options have improved, the incidence of hypothyroidism has increased according to data focused on the US and Europe.
Thyroid disease is a medical condition that affects the structure and/or function of the thyroid gland.The thyroid gland is located at the front of the neck and produces thyroid hormones [1] that travel through the blood to help regulate many other organs, meaning that it is an endocrine organ.
Myxedema is known to occur in various forms of hypothyroidism, as well as hyperthyroidism, including Graves disease. One of the hallmarks of Grave's disease is pretibial myxedema, myxedema of the lower limb. [2] Myxedema is more common in women than in men. [3] Myxedema can occur in:
Thyroiditis is generally caused by an immune system attack on the thyroid, resulting in inflammation and damage to the thyroid cells. This disease is often considered a malfunction of the immune system and can be associated with IgG4-related systemic disease, in which symptoms of autoimmune pancreatitis, retroperitoneal fibrosis and noninfectious aortitis also occur.
The condition typically resolves within three to six months. However, 20-56% of adult patients experience transient hypothyroidism, which can persist for years. Recurrent hypothyroidism is rare, occurring in about 2% of cases, and usually manifests within a year after diagnosis. Late recurrences have been reported.
In all three types of thyroiditis, there is inflammation of the thyroid gland which leads to clinical symptoms in three phases. The initial thyrotoxic phase is followed by hypothyroid phase before reaching a euthyroid phase where normal thyroid function in restored.
Myxedema coma is an extreme or decompensated form of hypothyroidism and while uncommon, is potentially lethal. [1] [2] [3] A person may have laboratory values identical to a "normal" hypothyroid state, but a stressful event (such as an infection, myocardial infarction, or stroke) precipitates the myxedema coma state, usually in the elderly.
