What are the Different Types of Thyroid Disease?

Rate This

There are several types of thyroiditis: postpartum thyroiditis, subacute thyroiditis, silent thyroiditis, Hashimoto’s thyroiditis, acute thyroiditis, drug-induced thyroiditis and radiation-induced thyroiditis.

Thyroiditis can cause hypothyroidism, hyperthyroidism or both. For example, with postpartum thyroiditis, patients start having symptoms of hyperthyroidism, followed by symptoms of hypothyroidism.

Thyroid Cancer

There are several types of thyroid cancer: anaplastic thyroid cancer, papillary thyroid cancer, follicular thyroid cancer, medullary thyroid cancer and thyroid lymphoma.

MedlinePlus pointed out that the most common type of thyroid cancer is papillary thyroid cancer, which is also the least dangerous type. Patients with thyroid cancer may undergo surgery, radiation therapy or thyroid hormone treatment.


When a patient has a goiter, she has an enlarged thyroid gland. Goiters are not a cancerous form of thyroid disease. Most cases of sporadic goiters have an unknown cause. Other cases result from certain medications, such as lithium.

MedlinePlus noted that colloid goiters tend to occur in areas where the soil is poor in iodine. With a toxic nodular goiter, the patient has an enlarged thyroid gland with nodules that produce excess thyroid hormone.

Graves’ Disease

An autoimmune disease, Graves’ diseases causes the thyroid gland to produce too much of the thyroid hormones. This thyroid disease is most common among women who are older than age 20, according to MedlinePlus.

Patients with Graves’ disease may experience anxiety, double vision, insomnia and menstrual irregularities.

Thyroid Nodules

A patient with thyroid nodules has growths in her thyroid, which may be solid or fluid-filled. Thyroid nodules may have benign nodules, which may not cause symptoms.

Thyroid cancer is the cancer that is increasing the fastest in cases. It also like hyperthyroidism and hypothyroidism affects women more than men with a ratio of 3 to 1. Why the numbers are on the rise is not definite. It may be because of the advanced technology for detection, or may be the changes in the environment (pollution and chemicals). The environmental changes affect the food chain dramatically.
