Therapy

The standard treatment for hypothyroidism is taking daily thyroid hormone replacement medication. Of course, medicines often come with side effects, and forgetting to take a pill might lead to more symptoms.

Self-care

13b. In adults requiring thyroid hormone replacement treatment for primary hypothyroidism, is combination treatment including levothyroxine and liothyronine superior to the use of levothyroxine alone? There is no consistently strong evidence of superiority of combination therapy over monotherapy with levothyroxine.

Nutrition

Clinical ethical principles in levothyroxine treatment for hypothyroidism revolve around two core ethical principles in medicine: the Principles of Beneficence and Non-Maleficence, which guide the risk/benefit analysis in clinical practice, and protect clinicians from deviating from practice to satisfy inappropriate patient demands.

What are the treatment options for hypothyroidism?

The challenges of titrating thyroid hormone therapy in specific groups such as the pediatric, pregnant, and elderly populations are considered. However, the topic of subclinical hypothyroidism (SCH) is not addressed, other than in the pediatric population, because of prior extensive reviews of this topic in adults ( 1–4 ).

What is the purpose of hypothyroidism treatment?

The treatment goals for hypothyroidism are to reverse clinical progression and correct metabolic derangements, as evidenced by normal blood levels of thyroid-stimulating hormone (TSH) and free thyroxine (T4). Thyroid hormone is administered to supplement or replace endogenous production.

Who should be treated for hypothyroidism?

Treatment is sometimes recommended already starting at TSH levels of over 6 mU/L in people with high levels of thyorid antibodies (Hashimoto's thyroiditis). That is done to prevent subclinical hypothyroidism from becoming overt hypothyroidism.

What is the primary goal of therapy for hyperthyroidism and hypothyroidism?

The goal of therapy is to correct the hypermetabolic state with the fewest side effects and the lowest incidence of hypothyroidism. Beta blockers and iodides are used as treatment adjuncts. Antithyroid drugs, radioactive iodine, and surgery are the main treatment options for persistent hyperthyroidism (Table 3).

When should you be treated for hypothyroidism?

If your TSH level is higher than 10 mIU/L, you should start treatment, because you will very likely develop symptoms of an underactive thyroid, even if you don't have them now.

What happens if you don't treat hypothyroidism?

Hypothyroidism may not cause noticeable symptoms in the early stages. Over time, untreated hypothyroidism can cause a number of health problems, such as obesity, joint pain, infertility and heart disease.

What happens hypothyroidism?

Hypothyroidism is a common condition where the thyroid doesn't create and release enough thyroid hormone into your bloodstream. This makes your metabolism slow down. Also called underactive thyroid, hypothyroidism can make you feel tired, gain weight and be unable to tolerate cold temperatures.

How do you treat hypothyroidism symptoms?

Standard treatment for hypothyroidism involves daily use of the synthetic thyroid hormone levothyroxine (Levo-T, Synthroid, others). This oral medication restores adequate hormone levels, reversing the signs and symptoms of hypothyroidism. You'll likely start to feel better soon after you start treatment.

Which of the following would be the goal in treating hyperthyroidism?

The ultimate goal for treating hyperthyroidism is to lower the amount of thyroid hormones to establish a healthy balance. This balance is essential to your body's ability to function at its best.

What is the goal for hyperthyroidism?

The goal of therapy is to correct the hypermetabolic state with the fewest side effects and the lowest incidence of hypothyroidism. Beta blockers and iodides are used as treatment adjuncts. Antithyroid drugs, radioactive iodine, and surgery are the main treatment options for persistent hyperthyroidism (Table 3).

Does mild hypothyroidism need to be treated?

ANSWER: For mild cases of hypothyroidism, not all patients need treatment. Occasionally, the condition may resolve without treatment. Follow-up appointments are important to monitor hypothyroidism over time, however. If hypothyroidism doesn't go away on its own within several months, then treatment is necessary.

What was the mainstay of thyroid hormone replacement therapy?

Until the 1970s, the mainstay of thyroid hormone replacement therapy was desiccated thyroid extracts. Three factors were likely responsible for LT 4 becoming the predominant therapy in the latter half of the 20th century: first, the isolation of T 4 in 1927 by Kendall ( 31 ); second, the synthesis of T 4 ( 32) and its better-absorbed sodium salt by Chalmers et al. ( 33 ); and third, the demonstration that the biologically active T 3 was generated from T 4 in humans ( 10 ).

What is the purpose of levothyroxine replacement therapy?

These are (i) to provide resolution of the patients' symptoms and hypothyroid signs, including biological and physiologic markers of hypothyroidism, ( ii) to achieve normalization of serum thyrotropin with improvement in thyroid hormone concentrations, and (iii) to avoid overtreatment (iatrogenic thyrotoxicosis), especially in the elderly.

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 ).

How long does it take for levothyroxine to work?

Intravenous levothyroxine treatment in severely hypothyroid patients may lead to improvement in cardiovascular, renal, pulmonary, and metabolic parameters within a week. Serum thyroxine and triiodothyronine concentrations may improve or normalize with a similar time frame, with more gradual improvement in serum TSH. Thus, the therapeutic endpoints in myxedema coma should be improved mental status, improved cardiac function, and improved pulmonary function. Measurement of thyroid hormones every 1–2 days is reasonable to ensure a favorable trajectory in the biochemical parameters. While optimal levels for serum TSH and thyroid hormones are not well defined in this circumstance, failure of TSH to trend down or for thyroid hormone levels to improve could be considered indications to increase levothyroxine therapy and/or add liothyronine therapy, whereas high serum triiodothyronine could be considered an indication to decrease therapy given safety concerns.

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 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 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.

HOW IS THE DOSE OF THYROID HORMONE CHOSEN?

When someone is first started on thyroid hormone the initial dose is carefully selected based on information such as a person’s weight, age, and other medical conditions. The dose will then need to be adjusted by a physician to keep the thyroid function normal. The physician will make sure the thyroid hormone dose is correct by performing a physical examination and checking TSH levels.

HOW DO I TAKE THYROID HORMONE?

When thyroid hormone is used to treat hypothyroidism, the goal of treatment is to keep thyroid function within the same range as people without thyroid problems. Keeping the TSH level in the normal range does this. The best time to take thyroid hormone is probably first thing in the morning on an empty stomach. This is because food in the stomach can affect the absorption of thyroid hormone. However, the most important thing is to be consistent, and take your thyroid hormone at the same time, and in the same way, every day. If you are taking several other medications, you should discuss the timing of your thyroid hormone dose with your physician. Sometimes taking your thyroid hormone at night can make it simpler to prevent your thyroid hormone from interacting with food or other medications.

WHAT ABOUT “NATURAL” THYROID HORMONES?

It is also available still as a prescription. Since pills made from animal thyroid are not purified, they contain hormones and proteins that never exist in the body outside of the thyroid gland. While desiccated thyroid contains both T4 and T3, the balance of T4 and T3 in animals is not the same as in humans, so the hormones in animal thyroid pills aren’t necessarily “natural” for the human body. Further, the amounts of both T4 and T3 can vary in every batch of desiccated thyroid, making it harder to keep blood levels right. Finally, even desiccated thyroid pills have chemicals (binders) in them to hold the pill together, so they are not completely “natural”. Desiccated animal thyroid is rarely prescribed today, and there is no evidence that desiccated thyroid has any advantage over synthetic T4.

WHAT ABOUT COMBINED T4 AND T3 TREATMENT?

Some hormone preparations containing both T4 and T3 are available in the United States ( Thyrolar ® ). Combination T4/T3 preparations contain much more T3 than is usually produced naturally within the body. Because of this, they can have the same side effects as T3 given by itself. It is also given once a day, ignoring the short life span of T3 in the body. There has been interest in whether a combination of T4 and T3, with a lower amount of T3 given more than once a day, might result in better treatment of hypothyroidism, especially in those patients that do not feel completely normal on T4 alone. In these cases, Cytomel ® (T3) is taken in addition to T4. A trial period of 3 – 6 months is reasonable to determine if combination T4 and T3 therapy will help.

What is the treatment for thyroid cancer?

After surgery for thyroid cancer, thyroid hormone is needed both to replace the function of the removed thyroid gland and to keep any small or residual amounts of thyroid cancer cells from growing (see Thyroid Cancer brochure ). Thyroid hormone suppression therapy is also an important part of the treatment ...

Why is thyroid hormone suppression used?
