The three indicators of grandpa's three inspections are:
1, thyroxine (T4, commonly known as "thyroid hormone"): T4 is a hormone secreted by the thyroid gland and plays an important role in the metabolism, growth and development of the body. Among the three items of A function, total thyroxine is usually measured.
2. Free thyroxine (FT4): Free thyroxine refers to thyroxine without binding protein, which exists in blood in free form. It is a direct reflection of thyroid activity and more accurately reflects the functional state of thyroid.
3. Thyroid stimulating hormone (TSH): TSH is a hormone secreted by the pituitary gland and plays a regulatory role in thyroid function. When thyroid function declines, the pituitary gland secretes more TSH, which stimulates the thyroid gland to produce more thyroxine.
By measuring the levels of thyroxine and TSH, the functional status of thyroid can be preliminarily evaluated, which is of great significance for the diagnosis and monitoring of thyroid diseases.
Thyroid gland is an important endocrine gland, which plays an important role in regulating the metabolism, growth and development of the body.
Common thyroid diseases and related symptoms
1. hyperthyroidism: hyperthyroidism is a disease caused by overactive thyroid. Common symptoms include palpitation, weight loss, anxiety, shaking hands and sweating.
2, hypothyroidism (hypothyroidism): hypothyroidism is a disease caused by thyroid insufficiency. Common symptoms include fatigue, weight gain, constipation, dry skin and depression.
3. Thyroid nodules and thyroiditis: Thyroid nodules are masses in thyroid tissue, which can be benign or malignant. Nodules are usually asymptomatic, but larger nodules may cause symptoms such as pharyngeal pressure and dysphagia. Thyroiditis is an inflammatory disease of the thyroid gland, including subacute thyroiditis and chronic thyroiditis. Common symptoms include sore throat, goiter, fever and fatigue.
