The disease is hereditary and may develop at any age in men or women, but it's much more common in women ages 20 to 30, according to the Department of Health and Human Services . Other risk factors include stress, pregnancy, and smoking.
What are the symptoms of hypothyroidism?
The signs and symptoms associated with hypothyroidism are well known and include, but are not limited to, dry skin, cold intolerance, constipation, slowed thinking, weight gain, coarse skin, puffiness, slowed heart rate, and delayed relaxation of ankle reflexes. The symptoms often have an insidious onset and overlap significantly between patients with thyroid disease and those without. Many signs and symptoms of thyroid dysfunction are neither sensitive nor specific ( 57 ). For example, signs and symptoms associated with hypothyroidism such as dry skin, fatigue, and constipation may not reveal themselves with modest degrees of hypothyroidism and could have other causes. Several studies report a correlation between signs and symptoms of hypothyroidism and biochemical disease either based on an increasing cumulative number of symptoms ( 57) or on an abnormal clinical score ( 58 ). Unfortunately, while several signs or symptoms show relatively high specificity, such as puffiness and slowed movements, the sensitivity is relatively low. Physiological, psychological, and biochemical biomarkers of thyroid status, in addition to thyroid hormone levels, are available. Physiological parameters include heart rate, pulse wave arrival time ( 59, 60 ), echocardiographic parameters of left ventricular function, Achilles reflex time ( 58 ), voice fundamental frequency, and basal metabolic rate ( 61–63 ). To illustrate the lack of specificity, basal metabolic rate, although profoundly affected by extreme hypothyroidism, is also affected by other conditions such as fever, malignancy, and nutritional status ( 64, 65 ). Pulse wave arrival time can also be affected by atherosclerosis and systemic sclerosis. Achilles reflex time seems to have a reasonable sensitivity of 77% and a good specificity of 93% to confirm or exclude hypothyroidism ( 58 ), but it is limited by the fact that a small percentage of euthyroid individuals have an abnormal reflex time. Other clinical indices used to assess thyroid function include psychiatric and neuropsychological measures. Various rating scales have been used to assess the degree of hypothyroidism ( 57, 58, 66–68 ). However, such clinical scores may not be sufficiently sensitive to signal subtle changes in thyroid status ( 69 ).
What is desiccated thyroid?
Desiccated thyroid or thyroid extract refers to preparations that are derived from the thyroid gland of animals. These preparations were the primary therapy for hypothyroidism until the advent of synthetic T 4 preparations in the 1960s. All commercially available prescription desiccated preparations are derived from pigs. As per the United States Pharmacopeia (USP), desiccated thyroid is “the cleaned, dried, and powdered thyroid gland previously deprived of connective tissue and fat. It is obtained from domesticated animals that are used for food by humans.” Tablets are measured for T 4 and T 3 content and are formulated into doses expressed as “grains” with 1 grain (65 mg) tablets containing 38 μg of T 4; 9 μg of T 3; protein-bound iodine; and unmeasured quantities of diiodothyronine, monoiodothyronine, and calcitonin, to which inactive ingredients are added for tablet stability. Varying strengths from fractions to multiples of a grain are commercially available. One process used to achieve specific dosage strengths is to mix different batches of the product during manufacture. The bioavailability of the T 4 and T 3 components has been shown to be the same between desiccated thyroid and synthetic preparations ( 473 ).
What is the TSH range for thyroid disease?
The TSH range for each trimester should be defined within the medical system in which care is being provided, with a generalized range as follows: 0.1–2.5 mIU/L for the first trimester, 0.2–3.0 mIU/L for the second trimester, and 0.3–3.0 mIU/L for the third trimester, as outlined in the ATA guidelines for the management of thyroid disease during pregnancy ( 1 ). Several studies, including the Generation R study by Medici et al. ( 262 ), have reported a higher TSH reference range during pregnancy, suggesting that ethnicity-based polymorphisms and dietary factors may play an important role in the thyroid axis response to pregnancy ( 262–266 ). The use of FT 4 immunoassays to further define the thyroid status during pregnancy is complicated by interferences associated with physiological changes during pregnancy. These changes include increases in TBG and nonesterified fatty acids, as well as lower concentrations of albumin. Liquid chromatography–tandem mass spectrometry (LC/MS/MS) assays eliminate some of these confounding factors ( 267 ). However, these assays are time consuming and more expensive. The increasing availability of LC/MS/MS assays may increase their acceptance and decrease their cost. LC/MS/MS appears to be associated with improved accuracy and reliability of FT 4 measurements ( 268) and is the method endorsed by the ATA guidelines for the diagnosis and management of thyroid disease during pregnancy ( 1 ).
What is factitious thyrotoxicosis?
Factitious thyrotoxicosis (thyrotoxicosis factitia) has traditionally been defined as a syndrome wherein patients surreptitiously ingest TH ( 452 ). It can be associated with Münchausen's syndrome (in which physical symptoms and signs of illness are intentionally produced) and is also associated with neuroses related to poor body image and concerns about increased body weight. More recently, the term factitious thyrotoxicosis has been expanded ( 453) to include instances of accidental LT 4 ingestion, such as in pediatric poisoning or pharmacy error, or through intentional or unintentional ingestion of supplements that contain thyroid gland extract ( 454 ). The treatment is the discontinuation of TH. In individuals with psychiatric disorders who are secretly taking TH, psychiatric consultation is warranted. Such a consult may not only provide relief for the underlying disorder, but also serves to protect the patient from thyrotoxic-related events. Factitious thyrotoxicosis has not been studied in a systematic manner. A strong recommendation is made despite low-quality evidence because there are benefits, but few risks.
What is the main molecule secreted by the thyroid gland?
The thyroid gland secretes a variety of iodinated and noniodinated molecules that collectively play important roles during prenatal and adult lives. Understanding what these molecules are and what they do informs our understanding of the therapy for hypothyroidism. The main noniodinated molecule secreted by the thyroid is calcitonin, an endogenous hormone with probable effects on calcium and bone metabolism. The other iodine-containing molecules include T 4, T 3, rT 3, 3,3′-diiodothyronine, 3,5-diiodothyronine (3,5-T 2 ), monoiodothyronine, and their decarboxylated forms known as thyronamines.
What is NTIS in patients?
As patients with normal thyroid function become critically ill, a progressive decline in circulating T 3 is observed, followed by decreases in serum T 4 and TSH if the clinical course does not improve. This stereotypic pattern, known as NTIS or alternatively “euthyroid-sick syndrome,” occurs without regard to the etiology of the primary illness, suggesting a physiologic, adaptive role. At the same time, since untreated hypothyroidism can itself lead to critical illness in the form of myxedema coma, debate continues as to whether NTIS patients might benefit from TH replacement.
What is LT 4?
An oral gel preparation that contains only LT 4, glycerin, gelatin, and water has been developed. The gelatin capsule contains LT 4 as a liquid ( 109 ). This formulation is in contrast to standard solid LT 4 tablets that contain excipients and dyes. Pabla et al. ( 110) studied in vitro dissolution of gel capsules and noted rapid and efficient dissolution at low pH concentrations. Colucci et al. ( 111) observed that gel capsules met the revised FDA potency guidelines of 95%–105% ( 103, 104) and also met equivalence criteria. At present, there are no prospective, randomized clinical trials in hypothyroid individuals comparing gel capsules to other commercial LT 4 preparations in terms of the serum FT 4, T 3, and TSH concentrations achieved during chronic therapy.
What percentage of the population is affected by hypothyroidism?

Hormone replacement should be initiated in a low dosage, ...
Is TSH elevated in primary hypothyroidism?
The evaluation of patients with new-onset hypothyroidism is quite limited. In patients with primary hypothyroidism, the thyroid-stimulating hormone (TSH) level is elevated, indicating that thyroid hormone production is insufficient to meet metabolic demands, and free thyroid hormone levels are depressed. In contrast, patients with secondary hypothyroidism have a low or undetectable TSH level.
What does TSH mean in medical terms?
Initiation and monitoring of treatment for hypothyroidism. (TSH = thyroid-stimulating hormone; T4 = thyroxine) [ corrected] Thyroid hormone replacement may have some benefits in patients with subclinical hypothyroidism, but there is also a potential for adverse effects, particularly in older patients.
Is there a screening for hypothyroidism?
The U.S. Preventive Services Task Force 23 does not recommend routine screening for hypothyroidism in asymptomatic persons. Recently, some expert panels 24 noted that screening may be beneficial in high-risk populations such as elderly women. However, widespread screening is not likely to be cost-effective.
Why is thyroid hormone highly protein bound?
Because thyroid hormone is highly protein bound, medical conditions that alter the amount of binding hormones and drugs that compete for binding may change the amount of available free thyroid hormone. The thyroid replacement dosage must be changed in response to alterations in binding status.
