Thyrotoxicosis is a condition that is caused by excessive secretion of thyroid hormones from your thyroid gland. It can be caused by an overactive thyroid gland (hyperthyroidism) or by the intake of too much of the hormones thyroxine or triiodothyronine. It happens when your thyroid gland produces too much of the hormones that regulate your metabolism. Symptoms of thyrotoxicosis may include nervousness, anxiety, restlessness, weight loss, sweating, heat intolerance, sensitivity to light, eye problems, difficulty sleeping and an unusually rapid heart rate.

Thyrotoxicosis is usually treated with a combination of medications, such as radioactive iodine, antithyroid drugs and beta blockers. Surgery may be needed in some cases, and other treatments may include dietary changes and lifestyle modifications like exercise to help manage symptoms. Thyrotoxicosis can be managed with proper treatment, and it is important to work closely with your doctor to get the best possible outcome.

Signs and symptoms of Thyrotoxicosis

  • Nervousness
  • Anxiety
  • Restlessness
  • Weight loss
  • Sweating
  • Heat intolerance
  • Sensitivity to light
  • Eye problems
  • Difficulty sleeping
  • Rapid heart rate

Possible Complications of Thyrotoxicosis

When left untreated, thyrotoxicosis can cause a variety of complications. Possible complications include:

  • Goiter
  • Heart rhythm disturbances
  • High blood pressure
  • Infertility
  • Bone loss (osteoporosis)
  • Psychosis
  • Miscarriage
  • Heart failure
  • Eye muscle weakness

Diagnosis of Thyrotoxicosis

The diagnosis of thyrotoxicosis is made based on the medical history, physical examination, lab tests, imaging tests, and other tests. A blood sample is typically taken to measure levels of hormones produced by the thyroid gland. Imaging tests are used to check for an enlarged thyroid or tumors. Thyroid antibodies tests are necessary to rule out autoimmune diseases.

Treatment of Thyrotoxicosis

Treatment for thyrotoxicosis primarily involves medications, surgery, dietary changes, and lifestyle modifications such as regular exercise. Medications to reduce thyroid hormone production include antithyroid drugs, radioactive iodine, or thyroidectomy (surgical removal of the thyroid gland). Beta blockers may be prescribed to control symptoms like rapid heart rate and anxiousness. Dietary changes may include reducing dietary intake of iodine and limiting consumption of certain foods and supplements containing iodine.
