Hashimotos thyroiditis very often results in hypothyroidism with bouts of hyperthyroidism. Symptoms of Hashimotos thyroiditis include weight gain, depression, mania, sensitivity to heat and cold, paresthesia, chronic fatigue, panic, bradycardia, tachycardia, congestive heart failure, high cholesterol, reactive hypoglycemia, constipation, migraines, muscle weakness, joint stiffness, menorrhagia, myxedematous psychosis, cramps, memory loss, vision problems, infertility and hair loss. The thyroid gland may become firm, large, and lobulated in Hashimotos thyroiditis, but changes in the thyroid can also be nonpalpable.[2] Enlargement of the thyroid is due to lymphocytic infiltration and fibrosis rather than tissue hypertrophy. Physiologically, antibodies against thyroid peroxidase (TPO) and/or thyroglobulin cause gradual destruction of follicles in the thyroid gland. Accordingly, the disease can be detected clinically by looking for these antibodies in the blood. 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.
