The most common symptoms include: fatigue, weight gain, pale or puffy face, feeling cold, joint and muscle pain, constipation, dry and thinning hair, heavy menstrual flow or irregular periods, depression, panic disorder, a slowed heart rate, and problems getting pregnant and miscarriages.[12] Hashimoto's disease is about seven times more common in women than in men. It can occur in teens and young women, but more commonly appears in middle age, particularly for men. People who develop Hashimoto's disease often have family members who have thyroid or other autoimmune diseases, and sometimes have other autoimmune diseases themselves.[13] The thyroid gland may become firm, large, and lobulated in Hashimoto's thyroiditis, but changes in the thyroid can also be nonpalpable.[14] Enlargement of the thyroid is due to lymphocytic infiltration and fibrosis, rather than tissue hypertrophy. While their role in the initial destruction of the follicles is unclear, antibodies against thyroid peroxidase or thyroglobulin are relevant, as they serve as markers for detecting the disease and its severity.[15] They are thought to be the secondary products of the T cell-mediated destruction of the gland.[16] It is also characterized by invasion of the thyroid tissue by leukocytes, mainly T-lymphocytes. A rare but serious complication is thyroid lymphoma, generally the B-cell type, non-Hodgkin lymphoma.[17]
