The topic Hyperactive Thyroid Gland you are seeking is a synonym, or alternative name, or is closely related to the medical condition Hyperthyroidism.

Quick Summary:

• Hyperthyroidism is a condition in which the thyroid gland (present in the neck) is overactive and produces too much of the hormone thyroxine, due to a variety of factors
• Thyroxine is responsible for regulating the body's metabolism. It stimulates cells of the body to produce proteins, and also increases the amount of oxygen used by them. It also has a very important role in fetal brain development
• There are two main forms of Hyperthyroidism:
  • Primary Hyperthyroidism: Hyperthyroidism is considered primary when it occurs due to dysfunction of the thyroid gland itself, and not due to factors extrinsic to the gland. This is a fairly common condition
  • Secondary Hyperthyroidism: Secondary Hyperthyroidism indicates that the dysfunction is caused by factors extrinsic to the thyroid gland (i.e., not due to a disorder within the thyroid). It is a much rarer form of Hyperthyroidism
• The cause depends on the type of Hyperthyroidism; this may include Graves’ disease (most common cause of the primary form) and thyroid stimulating hormone secreting pituitary adenoma (most common cause of the secondary form)
• The signs and symptoms of Hyperthyroidism may include rapid weight loss, irritability, heat sensitivity, diarrhea, irregular heartbeat, sweating, and fatigue. The associated symptoms of the underlying condition causing secondary Hyperthyroidism may be additionally noted
• The complications associated with Hyperthyroidism, particularly if it is unrecognized/untreated, may include osteoporosis, abnormal heart conditions, and thyroid storm or thyroid crisis
• A treatment of the condition may involve addressing the symptoms and treating the underlying cause. If necessary, the healthcare provider may administer certain anti-thyroid medications and recommend surgery too (to remove the thyroid gland)
• The prognosis is generally good with appropriate treatment, despite the requirement of medications for a lifetime in some cases. The prognosis also depends on the severity of the underlying associated condition (if any)
