People with hypothyroidism often have no or only mild symptoms. Numerous symptoms and signs are associated with hypothyroidism and can be related to the underlying cause, or a direct effect of having not enough thyroid hormones. [14] [15] Hashimoto's thyroiditis may present with the mass effect of a goitre (enlarged thyroid gland). [14]
There are five general types of thyroid disease, each with their own symptoms. A person may have one or several different types at the same time. The five groups are: Hypothyroidism (low function) caused by not having enough free thyroid hormones [2] Hyperthyroidism (high function) caused by having too many free thyroid hormones [2]
Myxedema psychosis is a relatively uncommon consequence of hypothyroidism, such as in Hashimoto's thyroiditis or in patients who have had the thyroid surgically removed and are not taking thyroxine. A chronically under-active thyroid can lead to slowly progressive dementia , delirium , and in extreme cases to hallucinations , coma , or ...
Many symptoms are attributed to the development of Hashimoto's thyroiditis. Symptoms can include: fatigue, weight gain, pale or puffy face, feeling cold, joint and muscle pain, constipation, dry and thinning hair, heavy menstrual flow or irregular periods, depression, a slowed heart rate, problems getting pregnant, miscarriages, [19] and ...
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 ...
It is often possible to diagnose myxedema on clinical grounds alone. Characteristic symptoms are weakness, cold intolerance, mental and physical slowness, dry skin, typical facies, and hoarse voice. Results of the total serum thyroxine and free thyroxine index tests usually will confirm the diagnosis. [9]
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.
A low amount of thyroxine (one of the two thyroid hormones) in the blood, due to lack of dietary iodine to make it, gives rise to high levels of thyroid stimulating hormone (TSH), which stimulates the thyroid gland to increase many biochemical processes; the cellular growth and proliferation can result in the characteristic swelling or hyperplasia of the thyroid gland, or goiter.
