Hashimoto’s Thyroiditis, also known as Hashimoto’s disease, is an autoimmune disorder where the body’s immune system mistakenly attacks the thyroid gland. This condition, first described by Japanese physician Dr. Hakaru Hashimoto in 1912, leads to chronic inflammation of the thyroid, often resulting in hypothyroidism (underactive thyroid). The thyroid gland, located at the base of the neck, produces hormones that regulate metabolism, energy levels, and overall hormonal balance. When the thyroid is under attack, its ability to produce these hormones diminishes, leading to various symptoms.
