Overview
- Hyperthyroidism (overactive thyroid) occurs when your thyroid gland produces too much of the hormone thyroxine. Hyperthyroidism can accelerate your body's metabolism, causing unintentional weight loss and a rapid or irregular heartbeat.Several treatments are available for hyperthyroidism. Doctors use anti-thyroid medications and radioactive iodine to slow the produc…
- In hyperthyroidism, an irritation of your thyroid known as thyroiditis allows too much thyroid hormone to enter your blood. This can lead to pain and discomfort. Thyroiditis can also occur as the result of pregnancy. This is usually short-term.
Treatment
- Hyperthyroidism can be treated with antithyroid medications that interfere with the production of thyroid hormones (primarily methimazole; propylthiouracil is now used only for women in the first trimester of pregnancy). Another option is radioactive iodine therapy to damage the cells that make thyroid hormones. In rare cases in which women do not respond to or have side effects fr…
- According to the American Thyroid Association, theres no cure for hypothyroidism. However, there are medications that can treat the disease. The goal of the medication is to improve your bodys thyroid function, restore hormone levels, and allow you to live a normal life.
- 1. Medication - the thyroid gland relies on iodine to make the thyroid hormones. Anti-thyroid drugs work by interfering with the gland's ability to use iodine. Around one in four people will experience a prolonged period of remission after one year or more of anti-thyroid medication. Side effects of the medications include skin rashes and joint pain. Patients on these drugs who experience feve…
- Exact treatment depends on the cause of the condition. There are three main methods of treatment for thyrotoxicosis:
Signs And Symptoms
- Hyperthyroidism can mimic other health problems, which can make it difficult for your doctor to diagnose. It can also cause a wide variety of signs and symptoms, including: 1. Unintentional weight loss, even when your appetite and food intake stay the same or increase 2. Rapid heartbeat (tachycardia) — commonly more than 100 beats a minute 3. Irregular heartbeat (arrhythmia) 4. P…
- Weight loss and increased appetite are among the most common clinical signs of this condition. Weight loss is seen in 95 to 98 percent of hyperthyroid cats, and a hearty appetite in 67 to 81 percent. Excessive thirst, increased urination, hyperactivity, unkempt appearance, panting, diarrhea and increased shedding have also been reported. Vomiting is seen in about 50 percent …
- The symptoms of hyperthyroidism include the following: 1. fatigue or muscle weakness 2. hand tremors 3. mood swings 4. nervousness or anxiety 5. rapid heartbeat 6. heart palpitations or irregular heartbeat 7. skin dryness 8. trouble sleeping 9. weight loss 10. increased frequency of bowel movements 11. light periods or skipping periods.Some people may develop a goiter, whic…
- Less than 10 percent of cats suffering from hyperthyroidism are referred to as apathetic. These patients exhibit atypical signs such as poor appetite, loss of appetite, depression, and weakness.
Diagnosis
- Because several common diseases of older cats-diabetes, inflammatory bowel disease, intestinal cancer and chronic kidney failure-share some of the clinical signs of hyperthyroidism, a battery of tests is in order. A CBC, chemistry panel and urinalysis alone will not diagnose hyperthyroidism, but they can certainly rule out diabetes and kidney failure. Hyperthyroid cats may have normal fi…
- Hyperthyroidism is diagnosed based on symptoms, physical exam, and blood tests to measure levels of thyroid stimulating hormone (TSH) and thyroid hormones T3 and T4. Your doctor may also decide to order either an ultrasound or a nuclear medicine scan of your thyroid to see if it has nodules, or whether it is inflamed or overactive.
- The signs of feline hyperthyroidism can overlap with those of chronic renal failure, chronic hepatic disease, and cancer (especially intestinal lymphoma). These diseases can be excluded on the basis of routine laboratory findings and thyroid function tests. Your veterinarian will conduct a battery of tests to zero in on a reliable diagnosis. Thoracic radiography and echocardiography m…
- In the United States, hypothyroidism is more common than hyperthyroidism. However, its not uncommon to have an overactive thyroid and then an underactive thyroid, or vice versa. Finding a skilled doctor who specializes in the thyroid, typically an endocrinologist, is an important part of your treatment plan.
Cause
- Hyperthyroidism can be caused by a number of conditions, including Graves' disease, Plummer's disease and thyroiditis.Your thyroid is a small, butterfly-shaped gland at the base of your neck, just below your Adam's apple. The thyroid gland has an enormous impact on your health. Every aspect of your metabolism is regulated by thyroid hormones.Your thyroid gland produces two m…
- The thyroid gland makes the hormones thyroxine (T4) and triiodothyronine (T3) that play an important role in the way your whole body functions. If your thyroid gland makes too much T4 and T3, this is defined as hyperthyroidism. The most common cause of hyperthyroidism is the autoimmune disorder Graves’ disease. In this disorder, the body makes an antibody (a protein pr…
- Hashimotos thyroiditis is the most common cause of hypothyroidism. With this condition, your body attacks its own immune system. Over time, this attack causes the thyroid to stop producing hormones as it should which leads to hypothyroidism. Like many autoimmune diseases, Hashimotos thyroiditis occurs more frequently in women than men. As its name suggests, hyper…
- The main cause of thyrotoxicosis is hyperthyroidism, which is an overactivity of the thyroid gland resulting in it producing excess levels of thyroid hormones. If the hyperthyroidism is due to an autoimmune cause, it is called Graves' disease. Other rarer causes of thyrotoxicosis include excessive intake of thyroid hormone in patients treated for hypothyroidism (an underactive thyro…
Pathophysiology
- The most common difference between the two diseases relates to hormone levels. Hypothyroidism leads to a decrease in hormones. Hyperthyroidism leads to an increase in hormone production.
- Thyrotoxicosis is the name given to the clinical effects experienced due to an excess of thyroid hormones in the bloodstream. Hormones produced by the thyroid gland control how fast or slow the body works (metabolic rate). Too much thyroid hormone (thyroxine and triiodothyronine) speeds up the metabolism and results in the signs and symptoms of thyrotoxicosis.
- When functioning correctly, the thyroid is able to properly respond to changes in temperature by adjusting the bodys basal metabolic rate (BMR) and releasing hormones to promote cellular release (aka sweating) or retention of heat, allowing the body to remain at a comfortable temperature. With hyperthyroidism, the body cannot regulate these hormones as easily, therefor…
Epidemiology
- Thyroid disease tends to be commoner in women than men (up to 10 times more). Thyrotoxicosis can occur at any age and there is a 1 in 100 chance of a woman developing it in her lifetime and a 1 in 1,000 risk for men. The number of new cases diagnosed each year is 3 per 1,000 women.
- Toxic multinodular goiter causes 5 percent of the cases of hyperthyroidism in the United States and can be 10 times more common in iodine-deficient areas. It typically occurs in patients older than 40 years with a long-standing goiter, and has a more insidious onset than Graves disease.10 Lymphocytic thyroiditis and postpartum (subacute lymphocytic) thyroiditis are transient inflam…
- Hyperthyroid crisis is rare. It has an incidence of 0.2 cases per 100,000 population and approximately 1-2% of patients with hyperthyroidism progress to a hyperthyroid crisis.
Prognosis
- Long-term implications of treated thyrotoxicosis depend on which of the treatment methods are used, but often result in the need for lifelong medication (thyroid hormone tablets) to be taken daily. Patients on medication should have blood tests taken by their GP at regular intervals to confirm that the dose remains correct. The majority of patients are able to find a medication regi…
- Agranulocytosis is the most serious complication of antithyroid drug therapy and is estimated to occur in 0.1 to 0.5 percent of patients treated with these drugs.28 The risk is higher in the first several months of therapy and may be higher with PTU than methimazole.5,9,15 It is extremely rare in patients taking less than 30 mg per day of methimazole.9 The onset of agranulocytosis i…
- 1. Untreated hyperthyroid crisis is usually fatal. 2. Although hyperthyroid storm is rare, it is a critical illness that can lead to multiorgan failure and carries a high death rate. 3. Even with early diagnosis and targeted treatment, the mortality rate of hyperthyroid crisis ranges from 10-30%. 4. It has a fatality rate of 50-90% if left untreated.
- No matter what treatment your dog receives, he will most likely need medication every day for the rest of his life. With treatment, however, many dogs enjoy years of quality life.
Complications
- Hyperthyroidism can lead to a number of complications: 1. Heart problems. Some of the most serious complications of hyperthyroidism involve the heart. These include a rapid heart rate, a heart rhythm disorder called atrial fibrillation that increases your risk of stroke, and congestive heart failure — a condition in which your heart can't circulate enough blood to meet your body's n…
- Hyperthyroidism results in high levels of T4 and T3 circulating in the blood. These hormones will speed up metabolism. When this happens, the following symptoms may occur: 1. increased heart rate 2. abnormal heartbeat rhythm (palpitations or \"pounding\") 3. increased body heat, causing one to feel warm even in a cool room 4. moist skin because of perspiration 5. increased activity …
Risk Factors
- Risk factors for hyperthyroidism, include: 1. A family history, particularly of Graves' disease 2. Female sex 3. A personal history of certain chronic illnesses, such as type 1 diabetes, pernicious anemia and primary adrenal insufficiency...
