![]() ![]() This condition results from hormone-producing nodules in the thyroid gland becoming enlarged and releasing excess thyroid hormone. It is not clear why people develop Graves’ disease, although researchers believe that genetics plays a role.Īnother cause of hyperthyroidism is multinodular goiter. In Graves’ disease, the immune system creates antibodies that signal the thyroid gland to grow and produce significantly more thyroid hormone than the body needs. The most common cause of hyperthyroidism is Graves’ disease. A person with a heightened metabolic rate may experience a raised heart rate, high blood pressure, and fatigue. This can speed up their metabolic processes. Hyperthyroidism is when a person has too much thyroid hormone in their body. A person typically takes thyroid hormone replacement daily as an oral pill. There is no cure for hypothyroidism, but a person can manage the condition with thyroid hormone replacement. ![]() When the body senses low thyroid hormone levels, it releases more TSH, so a high level of TSH typically indicates hypothyroidism. The body releases TSH to signal the thyroid gland to release thyroid hormones. Low levels of thyroxine in the blood indicate hypothyroidism. Thyroxine is a hormone released by the thyroid gland. These will assess levels of the thyroid-stimulating hormone (TSH) and thyroxine in a person’s blood. This exam can include checking the thyroid gland area for swelling, measuring the patient’s heart rate, and checking their reflexes.ĭoctors may also carry out blood tests as part of the diagnosis. DiagnosisĪfter discussing a person’s symptoms and family history, a doctor may perform a physical exam. ![]() This condition occurs when the gland tries to compensate for the lack of thyroid hormone. Hypothyroid symptoms can vary, but may include:Ī person may also develop a goiter, or enlargement of the thyroid gland. Having another autoimmune disorder, such as rheumatoid arthritis, type 1 diabetes, or lupus, also increases the risk for Hashimoto’s.ĭevelopment of the disease can be prolonged, occurring over months or even years. If a person has close family members with the condition, their risk of developing it can be greater. The exact cause of Hashimoto’s thyroiditis is unclear, but heredity may play a role. ![]() The gland then becomes inflamed, and hormone production falls. This is a condition in which a person’s immune system attacks their thyroid gland. The most common cause of hypothyroidism is Hashimoto’s thyroiditis. Turner syndrome, a chromosomal disorder affecting females.too much or too little iodine intake in the diet.a damaged or missing thyroid gland, often occurring from birth.some medications, such as lithium for bipolar disorder and sulfonylureas for diabetes.radiation therapy for head and neck cancers.surgical removal of part or all of the thyroid gland.Hypothyroidism is more prevalent in birth-assigned females and is more common than hyperthyroidism. Not having enough thyroid hormone can slow down a person’s metabolism and lead to several adverse symptoms. Hypothyroidism is when a person’s thyroid does not produce enough thyroid hormone. ![]()
