Emotional agitation: a high metabolic rate suggests high sympathetic excitability, which may be characterized by irritability, irritability and anxiety. 2. Overeating, diarrhea: people with high metabolic rate have faster gastrointestinal peristalsis, increased bowel movements, and are prone to hunger, leading to an increase in the amount of food they eat. 3. Weight loss: People with high metabolic rate will have increased energy consumption and increased protein breakdown, so they will lose weight. Increased metabolism is commonly associated with hyperthyroidism. Therefore, it is recommended to go to the hospital to improve the relevant examinations and make a clear diagnosis when high metabolic rate manifestations or symptoms occur.
