The basal metabolic rate is the rate of energy metabolism produced by the body in a waking and extremely quiet state, independent of muscle activity, ambient temperature, food and mental stress, and is the most basic physiological activity. The main hormone that increases the basal metabolic rate is thyroid hormone. Thyroid hormone mainly promotes catabolism, and when there is too much of it, the body’s catabolic ability will be enhanced. Patients may experience symptoms of high metabolism such as panic, sweating, hand trembling, diarrhea, weight loss, chills, fever and general weakness. In addition, high basal metabolic rate can also be seen in growth hormone and cortisol in glucocorticoids, among which growth hormone can promote protein synthesis and fat decomposition to achieve the effect of fat loss and muscle gain, while cortisol is less effective than thyroid hormone and growth hormone. If patients have high basal metabolic rate, it is recommended to consult a doctor in time to improve thyroid function and other tests to clarify the cause and treat the symptoms.
