Thyroid symptoms is an improper way to define the symptoms and signs of conditions affecting the thyroid gland.
Before proceeding with the list of the various symptoms, it is useful to briefly review what these diseases are and what they are characterized by:
- Hyperthyroidism. It is the direct consequence of an overactive thyroid producing excess thyroid hormones, even when they are not really needed.
In other words, hyperthyroidism occurs when the thyroid gland produces more thyroid hormones than the body needs. - Hypothyroidism. It is the exact opposite of hyperthyroidism. Therefore, it is the direct consequence of an underactive thyroid that does not produce enough thyroid hormones to meet the needs of the body.
- The goiter. It is the generalized pathological enlargement of the thyroid. Its onset can be associated with various problems, including the aforementioned hyperthyroidism and hypothyroidism.
- Thyroiditis. It is inflammation of the thyroid. Often it has an autoimmune origin.
- Nodules of the thyroid gland. They are anomalous protuberances of the thyroid gland, generally well delimited and circumscribed, having more often a benign than malignant nature.
- Thyroid cancer. It is the malignant tumor of the thyroid gland and represents a major cause of thyroidectomy, which is thyroid removal surgery.
