These conditions have different physiological manifestations and can affect multiple organ systems in the body. Hyperthyroidism is characterized by excessive thyroid hormone production by the thyroid gland. The most common cause of hyperthyroidism is Graves' disease, an autoimmune disorder in which the body's immune system produces antibodies that stimulate the thyroid gland to produce more thyroid hormones. Hyperthyroidism can also be caused by thyroid nodules or inflammation of the thyroid gland (thyroiditis). Physiologically, hyperthyroidism is associated with increased metabolic rate, heat production, and oxygen consumption. This results in symptoms such as weight loss, heat intolerance, increased heart rate, palpitations, and tremors. Hyperthyroidism can also lead to muscle weakness, fatigue, and decreased bone density. On the other hand, hypothyroidism is characterized by low thyroid hormone production by the thyroid gland. The most common cause of hypothyroidism is Hashimoto's thyroiditis, an autoimmune disorder in which the body's immune system attacks and damages the thyroid gland. Hypothyroidism can also be caused by thyroid surgery or radiation therapy. Physiologically, hypothyroidism is associated with decreased metabolic rate, heat production, and oxygen consumption. This results in symptoms such as weight gain, cold intolerance, fatigue, constipation, and dry skin. Hypothyroidism can also lead to cognitive impairment, depression, and decreased heart rate. In terms of laboratory tests, hyperthyroidism is characterized by low thyroid-stimulating hormone (TSH) levels and high levels of free thyroxine (T4) and triiodothyronine (T3) in the blood. In contrast, hypothyroidism is characterized by high TSH levels and low levels of T4 and T3 in the blood. In summary, hyperthyroidism and hypothyroidism are two common endocrine disorders that affect thyroid function and have different physiological manifestations. Hyperthyroidism is associated with increased metabolic rate and heat production, while hypothyroidism is associated with decreased metabolic rate and heat production. Understanding the physiology of these conditions is essential for their diagnosis and management in the context of the USMLE Step 1 exam. #endocrinephysiology #endocrinesystem #endocrineglands #fmge #fmgevideos #rapidrevisionfmge #fmgejan2023 #mbbslectures #nationalexitexam #nationalexittest #neetpg #usmlepreparation #usmlestep1 #fmge #usmle #drgbhanuprakash #medicalstudents #medicalstudent #medicalcollege #neetpg2023 #usmleprep #usmlephysiology #neetpgphysiology #mbbsphysiology #fmgephysiology
