Normal metabolism is mainly based on the basal metabolic rate, which is normal between -10% and +15%.
Basal metabolic rate refers to the metabolism of energy required for the body’s basal metabolism when fasting and without any stress. It should be measured when the body is awake and extremely quiet, unaffected by muscle activity, ambient temperature, food and stress. It is generally calculated as pulse rate plus pulse pressure minus 111.
Basal metabolic rate (BMR) varies physiologically with gender and age. It is on average higher in men than in women, and is higher in early childhood than in adulthood; the older the person, the lower the metabolic rate. In general, it is normal for the actual value of the basal metabolic rate to be within 10-15% of the normal average. If it exceeds 20% of the normal value, a pathological state is considered and is considered abnormal basal metabolism.
The normal range of basal metabolic rate is between -10% and +15%. If the basal metabolic rate is high, there is a possibility that the patient is suffering from hyperthyroidism, hyperadrenocorticism and other diseases, while a low basal metabolic rate may be due to cold conditions or malignant diseases, tumors, hypothyroidism and other diseases.
If a patient has an abnormal basal metabolic rate, he or she needs to go to the hospital in time for further examination and a clear diagnosis.
