What’s the difference between hyperthyroidism and hypothyroidism?
Hyperthyroidism is an overactive thyroid, when it produces too much thyroid hormone. Hypothyroidism is an underactive thyroid, when it does not produce enough. Hypothyroidism is more common than hyperthyroidism. Although the two conditions have different signs and symptoms, sometimes they overlap. For example, enlargement of the thyroid, called a goiter, can happen in both types of thyroid disease.

What Causes Hyperthyroidism and Hypothyroidism?
The causes and treatments of hyperthyroidism and hypothyroidism are very different. Graves’ disease is the most common cause of hyperthyroidism. It is an autoimmune disease in which your immune system attacks the thyroid, causing it to grow and release too much hormone. Other causes of hyperthyroidism include:
Small masses within the thyroid (called a toxic nodular goiter).
Thyroiditis, an inflammation of the thyroid due to a virus.
Postpartum thyroiditis (after giving birth).
Taking too much thyroid hormone.
Hypothyroidism occurs when your thyroid is either no longer working properly or has been removed or destroyed for medical reasons . It is more common in women and with age. Hashimoto’s thyroiditis, another autoimmune disease, is the most common cause of hypothyroidism
Causes of hypothyroidism:
Previous radioiodine or surgical treatment for hyperthyroidism,
thyroid cancer or other thyroid disease.
Previous radiation for other head and neck cancer.
Conditions that affect the pituitary gland in the brain
Hypothyroidism present at birth.
Medications.
