Hyperthyroidism
Moderate
Hyperthyroidism occurs when the thyroid gland produces more thyroid hormone than the body needs. The excess hormone can increase metabolism and cause symptoms such as rapid or irregular heartbeat, nervousness, sweating, heat intolerance, weight loss, tremor, and difficulty sleeping. Some people have few noticeable symptoms, while severe untreated disease can cause serious complications.

When to Seek Medical Attention
Seek urgent medical attention for a very rapid or irregular heartbeat, severe chest pain, fainting, marked agitation or confusion, high fever, severe weakness, vomiting, or rapidly worsening symptoms. These may indicate a serious complication of excessive thyroid hormone activity.

Overview
Hyperthyroidism occurs when the thyroid gland produces more thyroid hormone than the body needs. The excess hormone can increase metabolism and cause symptoms such as rapid or irregular heartbeat, nervousness, sweating, heat intolerance, weight loss, tremor, and difficulty sleeping. Some people have few noticeable symptoms, while severe untreated disease can cause serious complications.

Causes 4
The most common cause of hyperthyroidism is Graves disease, an autoimmune disorder in which antibodies stimulate the thyroid to produce excess hormone. Other causes include toxic multinodular goiter, toxic thyroid nodules, thyroid inflammation, excessive iodine exposure, and excessive thyroid hormone medication. Rarely, pituitary or other disorders can contribute. The appropriate treatment depends on the underlying cause.

Genetics
Hormonal Imbalance
Smoking
Risk Factors
Risk factors for hyperthyroidism depend on the underlying cause. Graves disease is more common in people with a family history of thyroid or autoimmune disorders and may be associated with other autoimmune conditions. Older age increases the likelihood of toxic thyroid nodules. Excess iodine exposure and certain medicines can also trigger thyroid overactivity in susceptible individuals.
Diagnosis
Diagnosis is based on a patient's medical history,
symptoms, physical examination and, when necessary,
laboratory or imaging investigations.
Diagnosis of hyperthyroidism usually begins with a medical history and physical examination followed by thyroid blood tests. A low thyroid-stimulating hormone level with elevated thyroid hormone levels supports the diagnosis. Additional testing may include thyroid antibody tests, radioactive iodine uptake studies, or thyroid ultrasound to identify the cause. The choice of testing depends on symptoms, examination findings, and the suspected underlying disorder.
Prevention
Key Prevention Tips
Some causes of hyperthyroidism cannot be prevented
Avoiding unnecessary excessive iodine exposure and taking thyroid medicines only as prescribed may reduce preventable causes
People with thyroid disease should attend recommended follow-up appointments and report new symptoms such as persistent palpitations, unexplained weight loss, tremor, or heat intolerance
Appropriate treatment of the underlying thyroid disorder can help prevent complications
Prevention Guidance
Some causes of hyperthyroidism cannot be prevented. Avoiding unnecessary excessive iodine exposure and taking thyroid medicines only as prescribed may reduce preventable causes. People with thyroid disease should attend recommended follow-up appointments and report new symptoms such as persistent palpitations, unexplained weight loss, tremor, or heat intolerance. Appropriate treatment of the underlying thyroid disorder can help prevent complications.
Reminder: Prevention recommendations should be tailored to your personal health status and risk factors.
