Now hyperthyroidism can happen a few different ways.

甲亢的产生有不同的原因。

It can develop when someone with hyperthyroidism stops their treatment, develops an infection or has surgery.

这可能发生于甲亢患者停止治疗时、发生感染或手术时。

Diagnosing hyperthyroidism is done by measuring blood levels of TSH, T3 , and T4 .

甲亢的诊断是通过测量血液中的TSH、T3和T4水平来实现的。

A thyroid storm is a life-threatening complication of hyperthyroidism where the body goes into a state of severe hypermetabolism.

甲状腺风暴是甲亢危及生命的并发症，即身体进入严重代谢亢进的状态。

There are ways to treat hyperthyroidism in cats, though.

不过，有一些方法可以治疗猫的甲状腺功能亢进症。

Hyperthyroidism is a common disease among older cats, and it can have seriously dangerous side effects.

甲状腺功能亢进症是老年猫的一种常见疾病，它会产生严重危险的副作用。

If the hyperthyroidism has been ongoing for a long time, there is a risk of developing congestive heart failure and osteoporosis.

如果甲亢已持续了很长时间，也有发生充血性心力衰竭和骨质疏松的风险。

And hypo- and hyperthyroidism occur when the thyroid gland makes too little or too much thyroid hormone.

当甲状腺产生的甲状腺激素过少或过多时，就会发生甲状腺功能减退症和甲状腺功能亢进症。

Hyperthyroidism can make the left ventricle of the heart grow larger and thicker, which in turn can cause heart failure.

甲状腺功能亢进会使心脏的左心室变大变厚，进而导致心力衰竭。

Once hyperthyroidism is confirmed, a radioactive iodine uptake test and a thyroid scan help determine the specific cause of the disorder.

一旦确诊甲亢，放射性碘摄取试验和甲状腺扫描将有助于确定该疾病的具体原因。

One example, is a struma ovarii tumor which is made up of only thyroid tissue and can release thyroid hormone which leads to hyperthyroidism.

其中一个例子是卵巢甲状腺肿，只由甲状腺组织组成，并且可以分泌甲状腺素，造成甲亢。

All the normal symptoms of hyperthyroidism become exaggerated, for example, heat intolerance turns into high fever and rapid heart rate turns into cardiac arrhythmia.

此时，甲亢的所有常见症状都会更严重，例如，热不耐受转变成高烧，心率加快转变成心律失常。

A secondary cause of hyperthyroidism is when there's a healthy thyroid that generates a lot of thyroid hormone in response to a TCH-secreting tumor in the anterior pituitary.

甲亢的一个继发性病因是健康的甲状腺在垂体前叶TSH分泌性肿瘤的作用下分泌过多甲状腺激素。

Treatment varies based on the exact cause of hyperthyroidism but generally involves drugs like beta blockers to treat the immediate symptoms and anti-thyroid drugs to block thyroid hormone production and release.

治疗方法因甲亢的确切病因而有所差异，但通常涉及用如β受体阻滞剂这类药物来治疗常见症状，以及抗甲状腺药物来阻止甲状腺激素的产生和释放。

Lots of different endocrine-related illnesses — like diabetes or hyperthyroidism — tend to be the result of either hyper (too much) or hypo (too little) secretion of certain hormones, which throw your homeostasis off balance.

许多不同的内分泌相关疾病——如糖尿病或甲状腺功能亢进——往往是某些激素分泌过多或过少的结果，这会使你的体内平衡失衡。

Fifth, the symptoms are not attributable to the physiologic effects of a drugs or medication, or due to a medical condition like hyperthyroidism which creates an excess of thyroid hormone, which can sometimes cause symptoms of anxiety and worry.

第五，这些症状不由药物、毒品的生理作用引起，也并非由如甲状腺功能亢进等疾病导致；甲亢产生过量的甲状腺激素，会引起焦虑和担忧的症状。
