Thyrotoxicosis and thyroid storm. The diagnosis of hyperthyroidism is made on the basis of symptoms and physical exam findings, and it is confirmed by laboratory tests showing excess thyroid hormones (see the Hyperthyroidism brochure). Grillo HC, Soldin SJ. Depending on how much the nodule shrinks, it may require continued surveillance and monitoring after the iodine treatment, and ultimately may need to be removed for other reasons, such as a concerning biopsy or large size that causes neck pressure. Remaley AT, 6. Most patients develop permanent hypothyroidism between two and six months after radioactive iodine ablation and require thyroid hormone supplementation.1,33 Free T4 and total T3 should be measured four to eight weeks after ablation; if hyperthyroidism persists, these indices should be monitored every four to six weeks and thyroid hormone replacement started in the early stages of hypothyroidism.1, Thyroidectomy. 2005;8(2):127–134.

Antithyroid drug regimen for treating Graves' hyperthyroidism. Bevan JS. Hyperthyroidism: Diagnosis and Treatment. The thyroid gland is a butterfly-shaped endocrine gland that is normally located in the lower front of the neck. Werner SC, Ingbar SH, Braverman LE, Utiger RD. (T3 = triiodothyronine; T4 = thyroxine; TSH = thyroid-stimulating hormone.). Patient information: See related handout on overactive thyroid gland (hyperthyroidism), written by the author of this article.

Greenberg DA, On the other hand, Hyperthyroidism is the state of the increased level of free thyroxin hormones is known as hyperthyroidism.
Nat Clin Pract Endocrinol Metab. Gulseren S, / afp Subsequent routine monitoring of CBC is unnecessary, but CBC with differential should be obtained if fever and/or pharyngitis develop. 27.

Toxic adenoma on radioactive iodine scan. The uptake is very low (0% to 2%) in patients with thyroiditis and high in patients with Graves disease, a toxic adenoma, or a toxic multinodular goiter.23,24, Iodine 123 is concentrated in multiple spots, The thyroid scan shows the distribution of radiotracer in the gland. Olesen JB, 2008;65(1):99–103.
The key difference between Graves Disease and hyperthyroidism is that the Graves’ disease is a pathological condition while the hyperthyroidism is a functional abnormality which is a result of an ongoing pathological process. Thyroid-adrenergic interactions: physiological and clinical implications. While medication works to control the production of thyroid hormone, it does not fix the underlying toxic nodule. Lee WJ, Hegediüs L, 5. In a Danish study, its prevalence among patients with thyrotoxicosis was 0.5%, as evaluated by scintigraphy.6 Painless thyroiditis can be triggered by childbirth (postpartum thyroiditis) or by use of medications such as lithium, interferon alfa, interleukin-2, and amiodarone.7, Gestational hyperthyroidism develops in the first trimester of pregnancy as a result of the stimulatory action of placental beta human chorionic gonadotropin (β-hCG), which shares structural features with TSH, on the thyroid gland.8 β-hCG-mediated hyperthyroidism can occasionally be caused by hyperemesis gravidarum and, rarely, by a gestational trophoblastic tumor.8, Other rare causes of hyperthyroidism are TSH-secreting pituitary adenoma, metastatic follicular thyroid cancer, and struma ovarii.9. 2016 Mar 1;93(5):363-370.

Order TSH, and if abnormal, follow up with additional evaluation or treatment depending on the findings. Miyauchi A, Clinical suspicion of hyperthyroidism should prompt laboratory testing (Figure 120–23). The increased stimulation by the thyroid hormones expands the volume of retro-orbital connective tissues. Qiang W, 9. It is the primary imaging modality used during pregnancy, lactation, and in amiodarone-induced thyrotoxicosis.24, Regardless of the cause of hyperthyroidism, the adrenergic symptoms are controlled by beta blockers (Table 5).25–28 Propranolol has the theoretical advantage of also inhibiting 5′-monodeiodinase, thus blocking peripheral conversion of T4 to T3.25 The choice of treatment modality for hyperthyroidism caused by overproduction of thyroid hormones depends on the patient's age, symptoms, comorbidities, and preference.25,26, Selective beta1 blocker; safer than propranolol in asthma or chronic obstructive pulmonary disease; once-daily dosing improves compliance, Immediate release: 10 to 40 mg orally every eight hours, Extended release: 80 to 160 mg orally once per day, Exacerbation of congestive heart failure or asthma, Decreases T4 to T3 conversion; nonselective beta blocker, 5 to 120 mg orally per day (can be given in divided doses), Contraindicated in the first trimester of pregnancy, Agranulocytosis not related to dose; liver dysfunction; rash, including ANCA-associated vasculitis, Drug of choice in the first trimester of pregnancy; carries a higher risk of liver failure than methimazole, Usually 10 to 30 millicurie, depending on uptake and the size of the thyroid gland, May aggravate hyperthyroidism in the early posttreatment period, Causes hypothyroidism three to six months after treatment, Contraindicated in severe Graves orbitopathy and in patients who are pregnant or nursing, Binds thyroid hormones in the intestine and thus increases fecal excretion, Prednisone: 20 to 40 mg orally per day for up to four weeks, Hydrocortisone: 100 mg intravenously every eight hours with subsequent taper, Hyperglycemia in patients with diabetes mellitus, otherwise few short-term adverse effects, Used in severe hyperthyroidism or thyroid storm to reduce T4 to T3 conversion; also used in severe subacute thyroiditis, Nephrotoxicity; gastrointestinal bleeding, May aggravate hyperthyroidism if given before an antithyroid agent, Give at least one hour after methimazole or propylthiouracil, Do not give before radioactive iodine treatment.
