Thyroid pathology: hyperthyroidism and hypothyroidism

THYROID PATHOLOGY

Occurs when the thyroid does not function properly, either because it is secreting too much T4 hormone or because it is not secreting enough

The most common cause of an overactive thyroid is Graves' disease. It occurs when the immune system creates antibodies that cause the thyroid to grow and produce more thyroid hormone T4 than the body needs.

Symptoms of an underactive thyroid include: high cholesterol. depression. fatigue. hair loss. Loss of memory. extremely dry skin. feeling of cold constipation.

Causes Graves' disease (the most common cause of hyperthyroidism) Inflammation (thyroiditis) of the thyroid due to viral infections, some medicines, or after pregnancy. Taking too much thyroid hormone (common) Noncancerous tumors of the thyroid or pituitary gland (rare)
