High thyroid antibodies are typically associated with autoimmune thyroid conditions such as Hashimoto's thyroiditis and Graves' disease. The symptoms experienced may vary depending on the specific condition. In Hashimoto's thyroiditis, common symptoms include fatigue, weight gain, sensitivity to cold, depression, dry skin, and constipation. Graves' disease, on the other hand, is characterized by symptoms like weight loss, rapid heartbeat, anxiety, irritability, tremors, and heat sensitivity. It's important to note that not everyone with high thyroid antibodies will necessarily experience symptoms, as the severity and manifestation can vary among individuals.
