High basal metabolic rate is characterized by excessive sweating, easy hunger (easily hungry), as well as emotional excitement or palpitations, and overeating. Common diseases with high basal metabolic rate include hyperthyroidism and tumor. Basal metabolic rate refers to the basal metabolism measured in the basal state, such as awake and lying still in the early morning, without the influence of body temperature or mood fluctuations, and is mainly measured by blood pressure and pulse rate. The normal basal metabolic rate is at 10%-15%, the basal metabolic rate of hyperthyroid patients is at 20%-40%, the basal metabolic rate of hypothyroid patients is 20%-40% lower than the normal value, and the basal metabolic rate will also increase when fever is present.
