Hashimoto’s disease (chronic lymphocytic thyroiditis), also called Hashimoto’s Thyroiditis, thyroiditis, or simply “Hashimoto’s,” is an autoimmune disease
in which the thyroid is attacked by the body’s immune system
. It's the most common form of thyroid disorder in the US
with over 14 million people suffering from its effects.
Our immune system is usually very good at keeping us healthy. When it recognizes foreign objects, such as bacteria or viruses, it sends an army of antibodies to attack those foreign objects and keep us healthy. But sometimes the immune system goes into attack against something that is not a foreign object, like the thyroid gland.
