What is Graves disease?
Graves’ disease (GD) is the most common cause of hyperthyroidism in children. This review gives an overview and update of management of GD.

What hormones are elevated in thyroid glands?
The secretion of T3 and T4, which occurs in thyroid gland follicles, is normally controlled by thyroid stimulating hormone (TSH), a protein secreted from the anterior pituitary. The secretion of TSH from the anterior pituitary is regulated by thyrotropin releasing hormone (TRH), a tripeptide produced in the hypothalamus. Thus, hypothalamic TRH stimulates the secretion of pituitary TSH which, in turn, stimulates secretion of T3 and T4 from the thyroid. When serum concentrations of thyroid hormones are elevated, TSH secretion is suppressed by a negative feed-back mechanism. While some cases of hyperthyroidism are secondary to pituitary tumors that secrete excess TSH, leading to over-stimulation of the thyroid and enhanced secretion of thyroid hormones, most cases of hyperthyroidism are due to either activating thyroid antibodies or intrathyroid nodules.
What is the most common treatment for hyperthyroidism?
Radioactive iodine is the most common treatment for hyperthyroidism. This treatment is where patients are given a pill containing actual radioactive iodine. When you take this pill the radioactive iodine is processed by your thyroid, and the thyroid dies.
How to treat hyperthyroidism?
Traditional treatment for hyperthyroidism can include medication and surgery. If the thyroid is completely removed, technically hyperthyroidism is reversed, however, now the patient has hypothyroidism and has to be on levothyroxine (synthetic thyroid hormone) for life.
What are the symptoms of hyperthyroidism?
Hyperthyroidism symptoms can include unexplained weight loss, heart palpitations, diarrhea, anxiety, insomnia, and excessive sweating.

In this article we'll explore conventional treatments ...
What does it mean when your thyroid is producing too much thyroxine?
While hyperthyroidism means that the thyroid is producing too much thyroxine, in hypothyroidism, the thyroid is producing too little thyroxine. Thyroxine or T4 is the inactive hormone produced by your thyroid. Hyperthyroidism can alternate with hypothyroid symptoms, which can make it confusing for patients.
How do beta blockers work?
Beta Blockers. Beta Blockers work by blocking the stimulatory effect of excitatory neurotransmitters, so they don’t affect thyroid levels directly. However, they are often prescribed to help with the rapid heart rate and racing heartbeat issues that many patients with hyperthyroidism experience.
Does thyroid hormone cause weight gain?
Hormones produced by the thyroid regulate metabolism. This can be a tricky dance, as women who are hyperthyroid typically experience weight loss, and those who are hypothyroid have weight gain. However, hyperthyroidism also can come with increased appetite.

Treatment
Signs and symptoms
- Hyperthyroidism presents with multiple symptoms that vary according to the age of the patient, duration of illness, magnitude of hormone excess, and presence of comorbid conditions. Symptoms are related to the thyroid hormones stimulation of catabolic enzymopathic activity and catabolism, and enhancement of sensitivity to catecholamines. Common symptoms and signs a…
Epidemiology
- 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…
Clinical significance
- Toxic adenomas are autonomously functioning nodules that are found most commonly in younger patients and in iodine-deficient areas.10
Symptoms
- Subacute thyroiditis produces an abrupt onset of thyrotoxic symptoms as hormone leaks from an inflamed gland. It often follows a viral illness. Symptoms usually resolve within eight months. This condition can be recurrent in some patients.11
Cause
- Iodine-induced hyperthyroidism can occur after intake of excess iodine in the diet, exposure to radiographic contrast media, or medications. Excess iodine increases the synthesis and release of thyroid hormone in iodine-deficient patients and in older patients with preexisting multinodular goiters.5 Amiodarone- (Cordarone-) induced hyperthyroidism can be found in up to 12 percent o…
Diagnosis
- A diagnostic approach to patients who present with signs and symptoms of hyperthyroidism is summarized in Figure 2.5,13 Measurement of the TSH level is the only initial test necessary in a patient with a possible diagnosis of hyperthyroidism without evidence of pituitary disease. Further testing is warranted if the TSH level is abnormal. An undetectable TSH level is diagnostic of hyp…
Mechanism of action
- Iodides block the peripheral conversion of thyroxine (T4) to triiodothyronine (T3) and inhibit hormone release. Iodides also are used as adjunctive therapy before emergency nonthyroid surgery, if beta blockers are unable to control the hyperthyroidism, and to reduce gland vascularity before surgery for Graves disease.9 Iodides are not used in the routine treatment of hyperthyroid…
Usage
- PTU is preferred for pregnant women because methimazole has been associated with rare congenital abnormalities. The starting dosage of PTU is 100 mg three times per day with a maintenance dosage of 100 to 200 mg daily.28 The goal is to keep the freeT4 level at the upper level of normal.9
Prognosis
- 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…
Prevention
- In 15 percent of patients, Graves ophthalmopathy can develop or be worsened by the use of radioactive iodine.17,19 The use of prednisone, 40 to 80 mg per day tapered over at least three months, can prevent or improve severe eye disease in two thirds of patients.19 Lower-dose radioactive iodine sometimes is used in patients with ophthalmopathy because posttreatment h…

Lifestyle and Home Remedies
- Once you begin treatment, symptoms of hyperthyroidism should subside and you should start feeling much better.
