Thyroid nodule causes, symptoms and treatment A thyroid nodule is a lump on the thyroid. The thyroid is located in the neck and is responsible for the regulation and release of hormones. Thyroid nodules – or cysts – can often be symptomless and go undetected, unless a doctor locates them during a check-up. If a thyroid nodule is large it may be easily visible and disrupt breathing. Often thyroid nodules are of low concern, but your doctor may run tests to ensure they are safe and won’t lead to further health concerns.


Causes and symptoms of thyroid nodules

causes of Thyroid nodulesMany factors can contribute to the cause of thyroid nodules. Common causes of thyroid nodules include:

  • Iodine deficiency: Iodine is used by the thyroid, but low levels can result in thyroid nodules. Although iodine deficiency can cause thyroid nodules, it is uncommon in America.
  • Overgrowth of thyroid tissue (adenoma): It is unknown as to why thyroid tissue would overgrow, but it can be a cause of thyroid nodules. Non-cancerous overgrowth of thyroid tissue may become bothersome due to size and can lead to hyperthyroidism.
  • Thyroid cyst: This usually occurs when an adenoma begins to break down.
  • Chronic thyroid inflammation (thyroiditis): An underlying illness can result in the thyroid becoming inflamed, like Hashimoto’s disease. This is commonly associated with hypothyroidism.
  • Multinodular goiter: This is the enlargement of the thyroid, either caused by a thyroid disorder or iodine deficiency.
  • Thyroid cancer: Only a small percentage of thyroid nodules are cancerous. A large thyroid nodule which causes pain is more inclined to be checked for cancer.

Thyroid nodules are typically symptomless, but to know if you have one they can often be felt by touching the neck. If it’s large, it can be seen on the neck and may lead to shortness of breath if it pushes on your esophagus.

Some symptoms, though, that may be associated with thyroid nodules are:

  • Unexplained weight loss
  • Intolerance to heat
  • Tremor
  • Nervousness
  • Rapid or irregular heartbeat

Treatment of thyroid nodules

treatment of thyroid nodulesWhether the thyroid nodule is cancerous or not determines the mode of treatment. Treatment for a benign thyroid nodule includes:

  • Monitoring the nodule
  • Thyroid hormone suppressant therapy
  • Surgery – if the nodule is bothersome
  • Radioactive iodine – if the nodule is causing hyperthyroidism
  • Anti-thyroid medications – if the nodule is causing hyperthyroidism

Unfortunately, there is no clear-cut way to prevent thyroid nodules. They are something that has to be monitored to ensure they don’t lead to more serious conditions.
