Inadequate secretion and function of the thyroid.
Condition where the thyroid gland is less active than normal, resulting in symptoms such as a low metabolic rate and lack of energy.
deficiency of thyroid activity
a condition of decreased thyroid gland activity resulting to weight gain, sluggishness, dryness of the skin, constipation, arthritis and slowing of the processes of the body.
Under active thyroid, which can result in several symptoms like hair loss, drooping/swollen eyes, yellow-orange skin, yellow bumps on eyelids, fatigue.
abnormally decreased function of the thyroid gland, characterized by a low metabolic rate and sluggishness.

Deficient activity of the thyroid gland, resulting in decreased metabolic rate and a general loss of energy or strength
a condition where insufficient function of the thyroid gland produces a general retardation of physical growth and depressed metabolism.
A functional disturbance in your Great Dane's thyroid gland. If diagnosed, your Great Dane will have very little thyroid activity, or none at all. Symptoms of hyperthyroidism in Great Dane's usually include: dry or coarse coat; awkward and/or slow movement. Treatment is available.
underactive thyroid state.
A medical condition that occurs when the thyroid gland does not produce enough of the metabolism-regulating hormones that are required for proper metabolism levels. In iguanas, this is most often caused by the feeding of too many cruciferous plants (see above), which contain goiterogens which interfere with normal thyroid function. Symptoms of hypothyroidism are decreased appetite, decreased growth while maintaining a "chubby" look, and lethargy, or decreased activity levels.
Hypothyroidism is a condition that can happen when your body doesn't produce enough thyroid hormone. Some of the symptoms are weakness, hair loss, constipation and feeling tired all the time.
A condition in which the thyroid gland is underactive.
decreased production of thyroid hormone, leading to symptoms of thyroid insufficiency.
Recommendation Test Adrenal Function"Cortisol and DHEA are among the hormones produced by the adrenal glands..."
Diminished production of thyroid hormone, leading to thyroid insufficiency.
A condition characterized by insufficient thyroid hormone ( T4 or thyroxine), which may lead to delayed growth and mental retardation. Treatment consists of administering a thyroid tablet daily, which prevents the onset of these symptoms.
Decreased function of the thyroid gland. Associated with fertility problems and a higher rate of stillbirths. | Back to previous page
Diminished production of thyroid hormone, leading to low metabolic rate, tendency to gain weight, and sleepiness.
The insufficient production of thyroid hormones. 2 A pathological condition resulting from thyroid insufficiency, which may lead to cretinism of myxedema ? Calcium 2 TBL ? Iodine as directed ? Magnesium 4 TBL am and pm ? Potassium 1 TBL am ? Substitute Sea salt for table salt ? Vitamin B complex stress formula as directed
A condition characterized by a low level of circulating thyroid hormone, causing inadequate stimulation of metabolic activity in body cells.
In adults, it is most common in women and is characterised by decrease in basal metabolic rate, tiredness and lethargy, sensitivity to cold and menstrual disturbances. If untreated, it progresses to full blown myxoedema. In infants, severe hypothyroidism leads to cretinism. In juveniles, the manifestations are intermediate, with less severe mental and developmental retardation and only mild symptoms of the adult form. When due to pituitary deficiency of thyrotropin secretion it is called secondary hypothyroidism.
Deficient activity of the thyroid gland ; also : a resultant bodily condition characterized by lowered metabolic rate and general loss of vigor.
Underproduction of thyroid hormone by the thyroidgland. The resulting lowered metabolism can interfere with the normal breakdownof hormones and may lead to lethargy. Women may suffer from elevated levelsof prolactin and estrogen, which can interfere with fertility.
An underactive thyroid gland.
(high-po-thy-royd-ism) Also known as myxoedema (mix-ee-dee-ma). When the thyroid gland fails to make enough thyroid hormone. Can present as obstructive sleep apnoea and snoring.
The medical definition is a thyroid hormone secretion deficiency. We expand the definition to mean any deficiency in thyroid gland activity. Hormone levels may be normal and yet thyroid activity can be low. This is due to other imbalances that prevent the thyroid hormone from acting.
A condition in which the thyroid gland produces an insufficient amount of thyroid hormone. The resulting lowered metabolism interferes with the normal breakdown of 'old' hormones and causes lethargy. Men will suffer from a lower sex drive and elevated prolactin (see Hyperprolactinemia), and women will suffer from elevated prolactin and estrogen, both of which will interfere with fertility.
Caused by an underactive thyroid, this affects hormone production and can cause irregular periods and breast milk production in women who aren’t pregnant.
a condition in which the baby is born with too little thyroid hormone.
a medical condition in which the thyroid gland produces too little thyroid hormone.
decreased production of thyroid hormone leading to low metabolic rate, weight gain, chronic drowsiness, dry skin and hair, and/or fluid accumulation and retention in connective tissues.
the result of a lowered level of circulating thyroid hormone

A condition that results in the thyroid gland's producing deficient amounts of thyroid hormone. Children with hypothyroidism may experience growth retardation.
Under production of the thyroid hormone by the thyroid gland.
Too little thyroid hormone. Symptoms include weight gain, constipation, dry skin, and sensitivity to the cold. Also called underactive thyroid.
underactivity of the thyroid gland
a treatable disorder which is a disease tested for by many newborn screening programs. Low thyroid levels in a newborn can cause major problems if left untreated.
A condition in which there is lower than normal production of thyroid hormone. Low thyroid levels can lead to a variety of effects, including weight gain and sleepiness.
Having too little thyroid hormone, which regulates the way the body converts food into energy. Return to previous page.

under-activity of the thyroid gland, causing tiredness, cramps, a slowed heart rate, and possibly weight gain
A condition caused by the underproduction of thyroid hormone, and one of the causes of Reinke's edema (see below).
Hypothyroidism is the disease state in humans and animals caused by insufficient production of thyroid hormone by the thyroid gland. There are several distinct causes for chronic hypothyroidism in human beings, the most common being Hashimoto's thyroiditis (an autoimmune disease) and radioiodine therapy for hyperthyroidism. Historically, iodine deficiency was the most common cause of hypothyroidism world-wide.
