Thyroid antibodies themselves do not typically cause symptoms. However, the conditions associated with thyroid antibodies, such as Hashimoto's thyroiditis or Graves' disease, can present with symptoms related to thyroid dysfunction. Common symptoms of Hashimoto's thyroiditis include fatigue, weight gain, depression, and sensitivity to cold. Graves' disease, on the other hand, may manifest with symptoms like weight loss, anxiety, rapid heartbeat, and heat intolerance. It is important to note that symptoms can vary among individuals, and a comprehensive evaluation by a healthcare professional is necessary for accurate diagnosis and treatment.
