AP PSYCHOLOGY

Detailed explanation-1: -The thyroid gland is a vital hormone gland: It plays a major role in the metabolism, growth and development of the human body. It helps to regulate many body functions by constantly releasing a steady amount of thyroid hormones into the bloodstream.

Detailed explanation-2: -Hyperthyroidism, excess thyroid hormone, promotes a hypermetabolic state characterized by increased resting energy expenditure, weight loss, reduced cholesterol levels, increased lipolysis, and gluconeogenesis (26, 184).

Detailed explanation-3: -Metabolism: thyroid hormone increases the basal metabolic rate. It increases the gene expression of Na+/K+ ATPase in different tissues leading to increased oxygen consumption, respiration rate, and body temperature. Depending on the metabolic status, it can induce lipolysis or lipid synthesis.

Detailed explanation-4: -There are many reasons for experiencing tiredness and fatigue. In people living with an underactive thyroid (hypothyroidism), the body’s metabolism slows down. This can often lead to many symptoms, including lethargy and fatigue. In people with an overactive thyroid (hyperthyroidism), the body’s metabolism speeds up.

Detailed explanation-5: -An increased level of iodine in your body can cause your thyroid to produce excess thyroid hormones. This can occasionally happen if you’re taking medicine that contains iodine, such as amiodarone, which is sometimes used to control an irregular heartbeat (arrhythmia).
