Enlarged thyroid gland

(Redirected from Goiter)

An enlarged thyroid gland, also known as a goitre, is a condition that can occur in dogs. The thyroid gland is a small organ in the neck that produces hormones that regulate metabolism and other bodily functions. When the thyroid gland becomes too large, it can cause problems such as shortness of breath, difficulty swallowing, weight loss or behavioral changes. In this blog post, you can find out more about the causes, symptoms and treatment options for an enlarged thyroid gland in dogs.

Causes of an enlarged thyroid gland in dogs

There are various factors that can lead to an enlarged thyroid gland in dogs. The most common are:

  • Underactive thyroid (hypothyroidism): This is a condition where the thyroid gland does not produce enough hormones. This can lead to a slowed metabolism, weight gain, hair loss, fatigue and other symptoms. To compensate for the lack of hormones, the thyroid gland can increase in size.
  • Hyperthyroidism (overactive thyroid): This is a condition in which the thyroid gland produces too much hormone. This can lead to an accelerated metabolism, weight loss, nervousness, palpitations and other symptoms. To regulate hormone production, the thyroid gland can increase in size.
  • Thyroiditis: This is an inflammation of the thyroid gland that can be triggered by an infection, an autoimmune disease or another cause. This can lead to pain, fever, loss of appetite and other symptoms. The inflammation can also lead to an enlargement of the thyroid gland.
  • Thyroid tumors: These are growths in the thyroid gland that can be benign or malignant. They can affect hormone production and lead to an enlargement of the thyroid gland. They can also exert pressure on the surrounding structures and lead to shortness of breath or difficulty swallowing.

Treatment options for an enlarged thyroid gland in dogs

Treatment of an enlarged thyroid gland in dogs depends on the cause and severity of the condition. Some possible options are:

  • Medication: there are several medications that can regulate the hormone production of the thyroid gland. They are used as needed to treat an underactive or overactive thyroid. The medication must be taken and monitored regularly.
  • Surgery: In some cases, surgery may be necessary to remove part or all of the thyroid gland. This may be the case for thyroid tumors or a severely enlarged thyroid gland that interferes with breathing or swallowing. Hormone replacement therapy may be necessary after an operation.
  • Radioiodine therapy: This is a special form of radiotherapy that uses radioactive iodine to destroy the thyroid gland. This can be used for thyroid tumors or hyperthyroidism. The treatment is very effective, but also expensive and requires a special facility.
