Answer:
Options A, E, and F: heat intolerance, weight loss, and tremor
Step-by-step explanation:
In hyperthyroidism, the thyroid gland overproduces thyroid hormone (TH) which are responsible for the regulation of the metabolism, specifically the basal metabolic rate. Excessive amounts of TH increase the basal metabolic rate which can cause the body to expend energy in the form of heat. The result of this is patient experiencing signs and symptoms of heat intolerance -- the sensation of feeling overheated, causing diaphoresis, or excessive sweating -- and weight loss without a concerted effort. Tremors of the hands are also common due to TH offsetting the expected physiology of the sympathetic nervous system, the "fight or flight" portion of the nervous system.
Weight gain would be a characteristic of hypothyroidism, the condition in which the patient's body is underproducing TH. Diarrhea can occur as the the patient's increased metabolism can cause a change in bowel habits, but more likely is a change in the frequency of bowel movements. Patients with hyperthyroidism may experience excessive amounts of urine production, which is known as polyuria, however, this does not translate automatically to increased frequency in urination.
The common symptoms of hyperthyroidism are heat intolerance, weight loss, and tremor as a result of too much TH increasing metabolic rate.
