Overview

Hyperthyroidism occurs when the thyroid gland produces too much thyroid hormone, accelerating the body's metabolism. The most common cause is Graves' disease (autoimmune), but it can also result from thyroid nodules, thyroiditis, or excessive iodine intake. Symptoms can be dramatic and affect nearly every system in the body. Treatment options include medication, radioactive iodine, or surgery, depending on the cause and severity.

Symptoms

Common Symptoms

  • Unintentional weight loss despite increased appetite
  • Rapid or irregular heartbeat (palpitations)
  • Anxiety, irritability, or nervousness
  • Heat intolerance and sweating
  • Fine tremor in the hands
  • Fatigue despite feeling 'wired'
  • More frequent bowel movements
  • Difficulty sleeping
  • Thin, warm, moist skin
  • Bulging eyes (in Graves' disease)

Diagnosis

Diagnosis typically involves clinical evaluation, medical history, blood tests, and appropriate imaging studies. A healthcare provider will assess symptoms, order relevant laboratory work, and may refer to a specialist for confirmation.

Treatments

Treatment depends on the underlying cause and severity. Options may include medication, lifestyle modifications (diet, exercise, stress management), and ongoing monitoring. Always work with a qualified healthcare provider to develop an appropriate treatment plan.
