Introduction
Hyperthyroidism, the full name of which is hyperfunction of the thyroid gland, is an endocrine disorder caused by the thyroid gland inappropriately and continuously producing and secreting excessive thyroid hormones. The severity of the condition depends on the individual case. If symptoms suggestive of hyperthyroidism occur, prompt medical attention is advised to obtain a definitive diagnosis through professional examination and to follow the physician's instructions for appropriate treatment, in order to prevent worsening of the condition.

Generally, hyperthyroidism, fully termed hyperthyroidism syndrome, is an endocrine disorder caused by the thyroid gland inappropriately and continuously producing and secreting excessive thyroid hormones. The severity of the condition depends on individual circumstances. A detailed analysis is as follows:

The pathogenesis of hyperthyroidism is associated with autoimmune thyroid nodules with autonomous hormone secretion, excessive intake of exogenous thyroid hormones, and other factors. It can lead to increased metabolic activity and sympathetic nervous system stimulation, causing symptoms such as excessive sweating, palpitations, hand tremors, increased appetite but weight loss, heat intolerance, insomnia, goiter, and exophthalmos (bulging eyes).

Most patients have a good prognosis with standardized treatment. However, if diagnosis and treatment are delayed or the condition is poorly controlled, serious complications may arise. For example, hyperthyroid heart disease can lead to arrhythmias, cardiac enlargement, and even heart failure. Thyroid storm is a severe and life-threatening emergency associated with hyperthyroidism that may present with high fever, profuse sweating, agitation, nausea, vomiting, diarrhea, and can be fatal if not promptly treated. Severe exophthalmos may lead to corneal ulcers, visual impairment, or even blindness. Additionally, prolonged hypermetabolism may affect bone health and increase the risk of osteoporosis.

If symptoms suggestive of hyperthyroidism appear, timely medical consultation is necessary. A definitive diagnosis should be made through professional examinations, and appropriate treatment should be conducted under medical guidance to prevent disease progression. Furthermore, maintaining a healthy lifestyle, balanced nutrition, moderate exercise, avoiding excessive fatigue and mental stress are important for recovery and prevention of recurrence.

How to tell if you have hyperthyroidism
To determine whether hyperthyroidism is present, symptoms such as persistent fever and unexplained rapid weight loss may serve as initial indicators. A definitive diagnosis requires medical evaluations including blood tests and imaging studies. A body temperature exceeding 37.3°C for more than three consecutive days, accompanied by chills, headache, or joint pain, may be related to infection, inflammation, or other diseases, and further examinations are needed to identify the underlying cause.

What does frequent premature ventricular contractions mean, and is it serious?
Physiological conditions are often related to lifestyle factors. Long-term sleep deprivation, mental stress, excessive consumption of coffee or strong tea may lead to abnormal myocardial excitability, triggering frequent ventricular premature beats. These cases are usually not serious; symptoms often improve once the triggers are removed, and they do not cause significant damage to cardiac structure or function. Pathological conditions, by contrast, are relatively complex.
