A Bixby native and Oklahoma State University student Andrew Steadley died from probable cardiac arrhythmia caused by Hashimoto's Disease, according to the Oklahoma State Medical Examiner's Office.
Andrew Steadley was found dead Friday, January 2, 2017, at his home in Stillwater. Steadley, 22, was an agri-business major and senior at OSU who was active in student government.
An autopsy report states Steadley suffered from chronic lymphocytic thyroiditis, also known as Hashimoto's disease. According to the Mayo Clinic, Hashimoto's disease is a condition in which your immune system attacks your thyroid gland.
Heart problems are listed as a possible complication of the disease.
