Decreased activity of the thyroid gland, which may be associated with dementia, depressed mood, hypoactive sexual desire disorder, and sleep disorders.
Underactivity of the thyroid gland, leading to reduced secretion of thyroid hormones and a reduction in basal metabolic rate. Commonly associated with goitre due to iodine deficiency.
Decreased activity of the thyroid gland accompanied by deficient release of thyroid hormone, which can result in a variety of signs and symptoms, sometimes including hypertension.
The condition resulting from an underactive thyroid gland.
The underproduction of thyroxin from the thyroid gland which results in listlessness, slow reactions, easily fatigued, and sluggishness, hyperthyroidism.
A disease in which the thyroid, a gland on the neck that helps to control the body’s rate of metabolism, produces abnormally slow burning of calories. Hypothyroidism can be screened for with simple blood tests. It is the most common medically-treatable cause of obesity.
Hypothyroidism results from depletion in the concentration of thyroid hormone in the body. Thyroid hormone is released by the thyroid gland situated at the base of the neck. This important hormone is fundamental for normal metabolic rates in adults and is essential for growth and maturation in children. Depletion of thyroid hormone may occur as a result of treatment for hyperthyroidism, damage to the thyroid gland (i.e., primary hypothyroidism), a deficiency of iodine in the diet, or by a disorder of the pituitary gland (i.e., secondary hypothyroidism). There are three major types of hypothyroidism, and these include congenital, juvenile, and adult.
Decreased activity of the thyroid gland.
Reduced secretion of hormones by the thyroid gland caused by removal of the thyroid, iodine or other drug therapy, disease, or endocrine deficiency. It may occur in infants as a congenital syndrome called cretinism.
A condition resulting from a deficiency of the thyroid hormone thyroxine, which regulates the metabolism of the body. When this hormone is decreased to abnormally low levels, there is a slowing of the metabolism. The decrease in energy production disrupts many vital functions, including heart rate and ability to regulate temperature. Older people tend to be more susceptible to hypothyroidism.
Subnormal artivity of the thyroid gland. If present at birth and untreated it leads to cretinism. In adult life it causes mental and physical slowing, undue sensitivity to cold, slowing of the pulse, weight gain, and coarsening of the skin (myxedema). The condition can be treated by administration of thyroxine.
The clinical consequences of inadequate levels of thyroid hormone in the body. When thyroid deficiency is long-standing or severe, it results in diminished basal metabolism, intolerance of the cold temperatures, fatigue, mental apathy, physical sluggishness, constipation, muscle aches, dry skin and hair, and coarsening of features. Collectively, these symptoms are called myxedema. In infancy, inadequate levels of thyroid hormone cause cretinism.
Condition caused by the thyroid gland being underactive and producing too little thyroid hormone.
A medical disorder characterized by an insufficient production of thyroid hormone by the thyroid gland.
Hypothyroidism refers to the inadequate production of thyroid hormones due to an underperforming thyroid gland. These hormones play a crucial role in metabolism, so a deficiency can cause many of the body’s functions to decelerate. The majority of hypothyroidism cases result from autoimmune disorders, such as Hashimoto’s thyroiditis. Less commonly, hypothyroidism can occur as a consequence of partial thyroid gland removal carried out to treat hyperthyroidism, which is an overactive thyroid condition.
Hypothyroidism symptoms encompass fatigue, lethargy, and an increased sensitivity to cold. Other possible symptoms include muscle weakness, cramps, a slower heart rate, dry skin, hair loss, constipation, a deepened voice, and weight gain. Women with the condition may have heavier menstrual periods. In some instances, a condition called myxedema can develop, leading to thickening of the skin and other tissues. The thyroid gland may also enlarge. If hypothyroidism develops during childhood, it can hinder growth and normal development.
The condition is diagnosed by evaluating the concentration of thyroid hormones in the blood. The treatment primarily involves hormone replacement therapy with thyroxine, generally a lifelong commitment. In adults, symptoms typically start to improve around three weeks after initiating the treatment. To ensure the dosage is correct, the hormone therapy is routinely monitored.
