pos: Hypothyroidism enough iodine in the diet, the most common cause of hypothyroidism is the autoimmune condition Hashimoto's thyroiditis. Less common causes include: previous treatment with radioactive iodine, injury to the hypothalamus or the anterior pituitary gland, certain medications, a lack of a functioning thyroid at birth, or previous thyroid surgery. The diagnosis of hypothyroidism, when suspected, can be confirmed with blood tests measuring thyroid-stimulating hormone (TSH) and thyroxine levels. Salt iodization has prevented hypothyroidism in many populations. Hypothyroidism can be treated with levothyroxine. The dose is adjusted according to symptoms and normalization of the thyroxine and TSH levels. Thyroid medication is

The thyroid may be affected by several diseases. Hyperthyroidism occurs when the gland produces excessive amounts of thyroid hormones, the most common cause being Graves' disease, an autoimmune disorder. In contrast, hypothyroidism is a state of insufficient thyroid hormone production. Worldwide, the most common cause is iodine deficiency. Thyroid hormones are important for development, and hypothyroidism secondary to iodine deficiency remains the leading cause of preventable intellectual disability. In iodine-sufficient regions, the most common cause of hypothyroidism is Hashimoto's thyroiditis, also

Neonatal hypothyroidism has been reported in cases of infants exposed to lithium, a mood stabilizer used to treat bipolar disorder, "in utero". In some instances, hypothyroidism detected by screening may be transient. One common cause of this is the presence of maternal antibodies that temporarily impair thyroid function for several weeks. The word "cretinism" is an old term for the state of mental and physical retardation resulting from untreated congenital hypothyroidism, usually due to iodine deficiency from birth because of low iodine levels in the soil and local food sources.

Transient hyperthyroid states in the acute phase, (a common observation in Hashimoto's thyroiditis), are rare in Ord's disease. Treatment is as with hypothyroidism, daily thyroxine(T4) and/or triiodothyronine(T3). Outside Europe a goitrous form of autoimmune thyroiditis (Hashimoto's Thyroiditis) is more common than Ord's disease.

Hashimoto's thyroiditis is an autoimmune disorder in which the thyroid gland is infltrated by the lymphocytes B-cell and T-cells. These progressively destroy the thyroid gland. In this way, Hasimoto's thyroiditis may have occurred insidiously, and only be noticed when thyroid hormone production decreases, causing symptoms of hypothyroidism. Hashimoto's is more common in females than males, much more common after the age of 60, and has known genetic risk factors. Also more common in individuals with Hashimoto's thyroiditis are type 1 diabetes, pernicious anaemia, Addison's disease vitiligo. Postpartum thyroiditis occurs in

In areas of the world with sufficient dietary iodine, hypothyroidism is most commonly caused by the autoimmune disease Hashimoto's thyroiditis (chronic autoimmune thyroiditis). Hashimoto's may be associated with a goiter. It is characterized by infiltration of the thyroid gland with T lymphocytes and autoantibodies against specific thyroid antigens such as thyroid peroxidase, thyroglobulin and the TSH receptor.

Primary thyroid B cell lymphoma affects fewer than one in a thousand persons, and it is more likely to affect those with long-standing autoimmune thyroiditis. This disorder is believed to be the most common cause of primary hypothyroidism in North America; as a cause of non-endemic goiter, it is among the most common. Hashimoto's thyroiditis affects about 5% of the population at some point in their life. About 1 to 1.5 in 1000 people have this disease at any point in time. It occurs between eight and fifteen times more often in women than in men.

Subclinical hypothyroidism is a milder form of hypothyroidism characterized by an elevated serum TSH level, but with a normal serum free thyroxine level. This milder form of hypothyroidism is most commonly caused by Hashimoto's thyroiditis. In adults it is diagnosed when TSH levels are greater than 5 mIU/L and less than 10mIU/L. The presentation of subclinical hypothyroidism is variable and classic signs and symptoms of hypothyroidism may not be observed. Of people with subclinical

Worldwide, over 90% of goitre cases are caused by iodine deficiency. The term is from the Latin "gutturia", meaning throat. Most goitres are of a benign nature. A goitre, associated with hypothyroidism or hyperthyroidism, may be present with symptoms of the underlying disorder. For hyperthyroidism, the most common symptoms are associated with adrenergic stimulation: tachycardia (increased heart rate), palpitations, nervousness, tremor, increased blood pressure and heat intolerance. Clinical manifestations are often

neg: Thyroid disease with a prevalence of 0.5% in males and 3% in females. Although thyroid nodules are common, thyroid cancer is rare. Thyroid cancer accounts for less than 1% of all cancer in the UK, though it is the most common endocrine tumor and makes up greater than 90% of all cancers of the endocrine glands. Symptoms of the condition vary with type: hypo- vs. hyperthyroidism, which are further described below. Possible symptoms of hypothyroidism are: Possible symptoms of hyperthyroidism are:Note: certain symptoms and physical changes can be seen in both hypothyroidism and hyperthyroidism —fatigue, fine / thinning hair, menstrual cycle irregularities,

neg: Telogen effluvium Telogen effluvium Telogen effluvium is a scalp disorder characterized by the thinning or shedding of hair resulting from the early entry of hair in the telogen phase (the resting phase of the hair follicle). Emotional or physiological stress may result in an alteration of the normal hair cycle and cause the disorder, with potential causes including eating disorders, fever, pregnancy and childbirth, chronic illness, major surgery, anemia, severe emotional disorders, crash diets, hypothyroidism, and drugs. Diagnostic tests, which may be performed to verify the diagnosis, include a trichogram, trichoscopy and biopsy. Effluvium can present with similar appearance to alopecia totalis,

neg: Canine pancreatitis It is suggested that genetics may play a part in the risk factor. Dogs suffering from diabetes mellitus, Cushing's disease (hyperadrenocorticism), hypothyroidism and epilepsy are at increased risk for pancreatitis. Diabetes and hypothyroidism are also associated with hyperlipidemia. Those with other types of gastrointestinal conditions and dogs who have had previous pancreatitis attacks are also at increased risk for the disorder. There are no approved treatments for canine pancreatitis. Treatment for this disease is supportive, and may require hospitalization to attend to the dog's nutritional and fluid needs, pain management, and addressing any other disease processes (infection, diabetes, etc.) while

neg: Young–Simpson syndrome Young–Simpson syndrome Young–Simpson syndrome (YSS) is a rare congenital disorder with symptoms including hypothyroidism, heart defects, facial dysmorphism, cryptorchidism in males, hypotonia, mental retardation and postnatal growth retardation. Other symptoms include transient hypothyroidism, macular degeneration and torticollis. The condition was discovered in 1987 and the name arose from the individuals who first reported the syndrome. An individual with YSS has been identified with having symptoms to a similar syndrome known as Ohdo Blepharophimosis syndrome, showing that it is quite difficult to diagnose the correct condition based on the symptoms present. Some doctors therefore consider these syndromes to be the same.

neg: Hypothyroidism form of thyroxine, known as levothyroxine (-thyroxine). In young and otherwise healthy people with overt hypothyroidism, a full replacement dose (adjusted by weight) can be started immediately; in the elderly and people with heart disease a lower starting dose is recommended to prevent over supplementation and risk of complications. Lower doses may be sufficient in those with subclinical hypothyroidism, while people with central hypothyroidism may require a higher than average dose. Blood free thyroxine and TSH levels are monitored to help determine whether the dose is adequate. This is done 4–8 weeks after the start of treatment or a change

neg: 18p- with 18p-, though not at the same frequency as in the distal 18q- population. Panhypopituitarism and hypothyroidism have each been diagnosed in a handful of individuals. Also, ketotic hypoglycemia has been reported in several individuals and usually presents itself around the age of three. There is an increased incidence of psychiatric conditions within the distal 18p- population. In one study, 2 of 3 people with 18p- had an anxiety disorder, 1 of 3 had a communication disorder, and 1 of 3 had a motor skills disorders, and 1 of 3 had a stereotypic movement disorder. Additional research with a larger

Neurologic diseases such as multiple sclerosis, complex partial seizures, strokes, brain tumors, Wilson's disease, traumatic brain injury, Huntington's disease, and complex migraines can mimic features of bipolar disorder. An EEG may be used to exclude neurological disorders such as epilepsy, and a CT scan or MRI of the head may be used to exclude brain lesions. Additionally, disorders of the endocrine system such as hypothyroidism, hyperthyroidism, and Cushing's disease are in the differential as is the connective tissue disease systemic lupus erythematosus. Infectious causes of mania that may appear similar to bipolar mania include

neg: LECT2 amyloidosis LECT2 amyloidosis LECT2 Amyloidosis (ALECT2) is a form of amyloidosis caused by the LECT2 protein. It was found to be the third most common (~3% of total) cause of amyloidosis in a set of more than 4,000 individuals studied at the Mayo Clinic; the first and second most common forms the disorder were AL amyloidosis and AA amyloidosis, respectively. Amyloidosis is a disorder in which the abnormal deposition of a protein in organs and/or tissues gradually leads to organ failure and/or tissue injury. Although more than 30 different proteins can cause amyloidosis, the disorder caused by LECT2 is distinctive in

neg: Hyperthyroidism iodine treatment, as small amounts of radioactive iodine may be found in breast milk even several weeks after the radioactive iodine treatment. A common outcome following radioiodine is a swing from hyperthyroidism to the easily treatable hypothyroidism, which occurs in 78% of those treated for Graves' thyrotoxicosis and in 40% of those with toxic multinodular goiter or solitary toxic adenoma. Use of higher doses of radioiodine reduces the incidence of treatment failure, with penalty for higher response to treatment consisting mostly of higher rates of eventual hypothyroidism which requires hormone treatment for life. There is increased sensitivity to radioiodine therapy

neg: Ord's thyroiditis Ord's thyroiditis Ord's thyroiditis is a common form of thyroiditis, an autoimmune disease where the body's own antibodies fight the cells of the thyroid. It is named after the physician, William Miller Ord, who first described it in 1877 and again in 1888. It is more common among women than men. Symptoms of Ord's thyroiditis include symptoms of hypothyroidism and atrophy of the thyroid gland. Physiologically, antibodies to thyroid peroxidase and/or thyroglobulin cause gradual destruction of follicles in the thyroid gland. Accordingly, the disease can be detected clinically by looking for these antibodies in the blood. It is also characterised

neg: Hypothyroidism women. As many women will not achieve this from dietary sources alone, the American Thyroid Association recommends a 150 µg daily supplement by mouth. Screening for hypothyroidism is performed in the newborn period in many countries, generally using TSH. This has led to the early identification of many cases and thus the prevention of developmental delay. It is the most widely used newborn screening test worldwide. While TSH-based screening will identify the most common causes, the addition of T testing is required to pick up the rarer central causes of neonatal hypothyroidism. If T determination is included in the screening

neg: Subacute thyroiditis Subacute thyroiditis Subacute thyroiditis is a form of thyroiditis that can be a cause of both thyrotoxicosis and hypothyroidism. It is uncommon and can affect individuals of both sexes and people of all ages. The most common form, subacute granulomatous, or de Quervain's, thyroiditis manifests as a sudden and painful enlargement of the thyroid gland accompanied with fever, malaise and muscle aches. Indirect evidence has implicated viral infection in the etiology of subacute thyroiditis. This evidence is limited to preceding upper respiratory tract infection, elevated viral antibody levels, and both seasonal and geographical clustering of cases. There may be a

Genetics play a role. The use of birth control pills does not affect the risk. Carpal tunnel is a feature of a form of Charcot-Marie-Tooth syndrome type 1 called hereditary neuropathy with susceptibility to pressure palsies. Other causes of this condition include intrinsic factors that exert pressure within the tunnel, and extrinsic factors (pressure exerted from outside the tunnel), which include benign tumors such as lipomas, ganglion, and vascular malformation. Severe carpal tunnel syndrome often is a symptom of

Mitochondrial haplogroup M, most common in Indian subjects and rare outside Southern Asia, accounts for nearly 30% of Romani people. A more detailed study of Polish Romani shows this to be of the M5 lineage, which is specific to India. Moreover, a form of the inherited disorder congenital myasthenia is found in Romani subjects. This form of the disorder, caused by the 1267delG mutation, is otherwise only known

neg: Obesity them can increase risk of obesity. Medical illnesses that increase obesity risk include several rare genetic syndromes (listed above) as well as some congenital or acquired conditions: hypothyroidism, Cushing's syndrome, growth hormone deficiency, and the eating disorders: binge eating disorder and night eating syndrome. However, obesity is not regarded as a psychiatric disorder, and therefore is not listed in the DSM-IVR as a psychiatric illness. The risk of overweight and obesity is higher in patients with psychiatric disorders than in persons without psychiatric disorders. Certain medications may cause weight gain or changes in body composition; these include insulin, sulfonylureas, thiazolidinediones,

neg: Thyroid needs. In order to detect hypothyroidism in newborn babies, to prevent growth and development abnormalities in later life, many countries have newborn screening programs at birth. Infants with thyroid hormone deficiency (congenital hypothyroidism) can manifest problems of physical growth and development as well as brain development, termed cretinism. Children with congenital hypothyroidism are treated supplementally with levothyroxine, which facilitates normal growth and development. Mucinous, clear secretions may collect within these cysts to form either spherical masses or fusiform swellings, rarely larger than 2 to 3 cm in diameter. These are present in the midline of the neck anterior to the

Yearly thyroid function tests are recommended in people with Down syndrome, as they are at higher risk of thyroid disease. Most people with hypothyroidism symptoms and confirmed thyroxine deficiency are treated with a synthetic long-acting

Mitochondrial haplogroup M, most common in Indian subjects and rare outside Southern Asia, accounts for nearly 30% of Romani people. A more detailed study of Polish Roma shows this to be of the M5 lineage, which is specific to India. Moreover, a form of the inherited disorder congenital myasthenia is found in Romani subjects. This form of the disorder, caused by the 1267delG mutation, is otherwise known only in subjects of Indian ancestry. This is considered to be the best evidence of the Indian

neg: Hypothyroidism important in making decisions about treatment, and should, therefore, be determined in women with abnormal thyroid function tests. Determination of TPO antibodies may be considered as part of the assessment of recurrent miscarriage, as subtle thyroid dysfunction can be associated with pregnancy loss, but this recommendation is not universal, and presence of thyroid antibodies may not predict future outcome. Hypothyroidism may be prevented in a population by adding iodine to commonly used foods. This public health measure has eliminated endemic childhood hypothyroidism in countries where it was once common. In addition to promoting the consumption of iodine-rich foods such as

As the child grows up, these levels are checked regularly to maintain the right dose. The dose increases as the child grows. Most children born with congenital hypothyroidism and correctly treated with thyroxine grow and develop normally in all respects. Even most of those with athyreosis and undetectable T levels at birth develop with normal intelligence, although as a population academic performance tends to be below that of siblings and mild learning problems occur in some. Congenital hypothyroidism is the most common

neg: Thought disorder Thought disorder Thought disorder (TD) or formal thought disorder (FTD) refers to disorganized thinking as evidenced by disorganized speech. Specific thought disorders include derailment, poverty of speech, tangentiality, illogicality, perseveration, and thought blocking. Psychiatrists consider formal thought disorder as being one of two types of disordered thinking, with the other type being delusions. The latter involves "content" while the former involves "form". Although the term "thought disorder" can refer to either type, in common parlance it refers most often to a disorder of thought "form" also known as formal thought disorder. Eugen Bleuler, who named schizophrenia, held that thought disorder

neg: Delusional parasitosis this phenomenon as "monosymptomatic hypochondriacal psychosis", and sometimes as "true" delusional parasitosis. In the DSM-IV, it corresponds with "delusional disorder, somatic type". Secondary functional delusional parasitosis occurs when the delusions are associated with a psychiatric condition such as schizophrenia, obsessive-compulsive disorder or clinical depression. Secondary organic delusional parasitosis occurs when a medical illness or substance (medical or recreational) use causes the patient's symptoms. In the DSM-IV this situation corresponds with "psychotic disorder due to general medical condition". Physical illnesses that can underlie secondary organic delusional parasitosis include: hypothyroidism, cancer, cerebrovascular disease, tuberculosis, neurological disorders, vitamin B12 deficiency, and diabetes mellitus.

neg: Mental health in education some form of mental disorder. About 21% will suffer from a disorder that is categorized as “severe,” meaning that the disorder impairs their daily functioning, but almost two-thirds of these adolescents will not receive formal mental health support. The most common types of disorders among adolescents as reported by the NIMH is anxiety disorders (including Generalized Anxiety Disorder, phobias, post-traumatic stress disorder, obsessive-compulsive disorder, and others), with a lifetime prevalence of about 25% in youth aged 13-18 and 6% of those cases being categorized as severe. Next is mood disorders (major depressive disorder, dysthymic disorder, and/or bipolar disorder), with a

Sometimes, "temporomandibular joint dysfunction" is described as the most common form of temporomandibular disorder, whereas many other sources use the term temporomandibular disorder synonymously, or instead of the term temporomandibular joint dysfunction. In turn, the term temporomandibular disorder is described as "a clinical term [referring to] musculoskeletal disorders affecting the temporomandibular joints and their associated musculature. It is a collective term which represents a diverse group of pathologies involving the temporomandibular joint, the muscles of mastication, or both". Another definition of temporomandibular disorders is "a group of conditions with similar signs

The Sheltie carries type III of von Willebrands, which is the most severe of the three levels. There are DNA tests that were developed to find von Willebrands in Shelties. It can be done at any age, and it will give three results: affected, carrier or non-affected. Shelties may also suffer from hypothyroidism, which is the under-functioning thyroid gland. It is an autoimmune disease where the immune system attacks the thyroid gland. Clinical symptoms include hair loss or lack of

One of these fragments gives rise to fibrils of beta-amyloid, which form clumps that deposit outside neurons in dense formations known as senile plaques. Parkinson's disease is the second most common neurodegenerative disorder and manifests as bradykinesia, rigidity, resting tremor and posture instability. The crude prevalence rate of PD has been reported to range from 15 per 100,000 to 12,500 per 100,000, and the incidence of PD from 15 per 100,000 to 328 per 100,000, with the disease being less common in Asian countries.

At 6 months postpartum, 21% of women still report perineal pain and 11-49% report sexual problems or painful intercourse. Peripartum cardiomyopathy is decrease in heart function which occurs in the last month of pregnancy, or up to 6 months post-pregnancy. It increases the risk of congestive heart failure, heart arrhythmias, thromboembolism, and cardiac arrest. Postpartum thyroiditis is a phenomenon observed following pregnancy and may involve hyperthyroidism, hypothyroidism or the two sequentially. It affects about 5% of all women within a year after giving

It may cause depressed patients to be noncompliant in their treatment, and the effects of certain substances can worsen the effects of depression. Other psychiatric disorders that may predict treatment-resistant depression include personality disorders, obsessive compulsive disorder, and eating disorders. Some people who are diagnosed with treatment-resistant depression may have an underlying undiagnosed health condition that is causing or contributing to their depression. Endocrine disorders like hypothyroidism, Cushing's disease, and Addison's disease are among the most commonly identified

neg: Maternal hypothyroidism suppressed psychomotor development and slightly lower IQ. In a study of induced hypothyroidism in pregnant rats they were able to find lower levels of growth hormone in both the blood and pituitary gland of the offspring. This study also looked at neural development in rats and found that maternal hypothyroidism in rat mothers is related to deterioration, damage, disorganization and malformation of neurons and dendrites in the pups, which may result from an impaired antioxidant defense system and high levels of oxidative stress. Maternal hypothyroidism Maternal hypothyroidism is hypothyroidism in pregnant mothers. Even with appropriate treatment, it may pose risks

The main goal is to make sure that patients do not harm themselves. The most common treatment for reducing bipolar II disorder symptoms is medication, usually in the form of mood stabilizers. However, treatment with mood stabilizers may produce a flat affect in the patient, which is dose-dependent. Concurrent use of SSRI antidepressants may help some with bipolar II disorder, though these medications should be used with caution because it is believed that they may cause a hypomanic

It is either autosomal recessive or autosomal dominant. The signs/symptoms of this condition are consistent with the following: 2-hydroxyglutaric aciduria is an organic aciduria, and because of the stereoisomeric property of 2-hydroxyglutarate different variants of this disorder are distinguished: The L-2 form is more common, severe, and mainly affects the central nervous system.

Symptoms may include weakness, trouble breathing, and loss of appetite. Complications may include seizures, coma, rhabdomyolysis, or softening of the bones. Causes include alcoholism, refeeding in those with malnutrition, diabetic ketoacidosis, burns, hyperventilation, and certain medications. It may also occur in the setting of hyperparathyroidism, hypothyroidism, and Cushing syndrome. It is diagnosed based on a blood phosphate concentration of less than 0.81 mmol/L (2.5 mg/dL). When levels are below 0.32 mmol/L (1.0 mg/dL) it is deemed to be severe. Treatment depends on

Medications can also cause side effects that mimic symptoms of CFS. Central sensitization, or increased sensitivity to sensory stimuli such as pain have been observed in CFS. Sensitivity to pain increases post-exertionally, which is opposite to the normal pattern. Gradual or sudden onset of the illness may occur, and studies have mixed results as to which occurs

Juvenile cellulitis, also known as puppy strangles, is a skin disease of puppies of unknown etiology, which most likely has a hereditary component related to the immune system. Some systemic diseases can become symptomatic as a skin disorder. These include many endocrine (hormonal) abnormalities, such as hypothyroidism, Cushing's syndrome (hyperadrenalcorticism), and tumors of the ovaries or testicles. Many canine skin disorders can have a basis in poor nutrition. The supplementation of both omega fatty acids, 3 and 6, have been shown to mediate the inflammatory skin response seen in

The differential diagnosis is made during the evaluation on the basis of the person's medical history, physical examination, and laboratory investigations. As with many other medically unexplained syndromes, there is no universally accepted treatment or cure for fibromyalgia, and treatment typically consists of symptom management. Developments in the understanding of the pathophysiology of the disorder have led to improvements in treatment, which include prescription

neg: Tic as an "other specified" or "unspecified" tic disorder. Tests may be ordered as necessary to rule out other conditions: For example, when diagnostic confusion between tics and seizure activity exists, an EEG may be ordered, or symptoms may indicate that an MRI is needed to rule out brain abnormalities. TSH levels can be measured to rule out hypothyroidism, which can be a cause of tics. Brain imaging studies are not usually warranted. In teenagers and adults presenting with a sudden onset of tics and other behavioral symptoms, a urine drug screen for cocaine and stimulants might be necessary. If a

On long-distance races, they require considerable care and attention on the trail at rest stops. The Alaskan husky is generally a healthy dog. Some strains are prone to genetic health problems similar to those found in purebred dog breeds. These may include PRA, hypothyroidism, etc. Dogs with a congenital deformation of the larynx, termed "wheezers", occasionally occur. This disorder typically causes the dog to make a wheezing

neg: Major depressive disorder this has improved somewhat in more recent studies. Before diagnosing a major depressive disorder, in general a doctor performs a medical examination and selected investigations to rule out other causes of symptoms. These include blood tests measuring TSH and thyroxine to exclude hypothyroidism; basic electrolytes and serum calcium to rule out a metabolic disturbance; and a full blood count including ESR to rule out a systemic infection or chronic disease. Adverse affective reactions to medications or alcohol misuse are often ruled out, as well. Testosterone levels may be evaluated to diagnose hypogonadism, a cause of depression in men. Vitamin D

Myxedema can occur in the lower leg (pretibial myxedema) and behind the eyes (exophthalmos). Severe cases, requiring hospitalization can exhibit signs of hypothermia, hypoglycemia, hypotension, respiratory depression, and coma. Myxedema is known to occur in various forms of hypothyroidism, and also in Graves' disease. One of the hallmarks of Grave's disease is pretibial myxedema, myxedema of the lower limb. Myxedema is more common in women than in men. Myxedema can occur in: Myxedema describes a specific form of cutaneous

Muscle weakness and pain are not as common in patients with hemolytic PFK deficiency. Presentation of the canine form of the disease is similar to that of the human form. Most notably, PFK deficient dogs suffer from mild, but persistent, anemia with hemolytic episodes, exercise intolerance, hemoglobinuria, and pale or jaundiced mucous membranes. Muscle weakness and cramping are not uncommon symptoms, but they are not as common as they are in human PFKM deficiency. In order

The severity of myxedema, and its associated risk of mortality and complications, created interest in discovering effective treatments for hypothyroidism. Transplantation of thyroid tissue demonstrated some efficacy, but recurrences of hypothyroidism was relatively common, and sometimes required multiple repeat transplantations of thyroid tissue. In 1891, the English physician George Redmayne Murray introduced subcutaneously injected sheep thyroid extract, followed shortly after by an oral formulation. Purified thyroxine was introduced in 1914 and

Barnes treated hypothyroidism by prescribing patients a daily dose of thyroid hormone. He recommended starting with a small dose, and then slowly increasing the dosage in monthly intervals until symptoms resolved and waking body temperature was between 97.8F and 98.2F. He also recommended never surpassing 3 grains of desiccated thyroid. For most patients, he recommended continuing thyroid medication for life at that optimal dose, though some
