Basal metabolism mostly refers to the basal metabolic rate. The formula for calculating basal metabolic rate is basal metabolic rate % = (pulse rate + pulse pressure) – 111. Pulse rate refers to the heart rate, and pulse pressure = systolic – diastolic blood pressure, the normal range of which is related to age, sex, etc.
Basal metabolic rate refers to the rate at which the body metabolizes the energy it expends on its own in the absence of external interference. It is measured in a fasting, non-exercising state at room temperature in a quiet, awake state.
There are many factors affecting the basal metabolic rate, and its normal range is within plus or minus 10%. A basal metabolic rate of <10% suggests a low basal metabolic rate; a basal metabolic rate of >20% suggests a high basal metabolic rate.
The increase or decrease of basal metabolic rate can be seen in hypothyroidism, hyperthyroidism, diabetes, malignant tumors and other diseases, but also can be seen in the healthy people who love to exercise. However, if the basal metabolic rate suddenly changes within a short period of time, it is mostly caused by diseases, and it is recommended to consult a doctor in time, under the guidance of the doctor, improve the relevant examinations, clarify the cause of the disease and standardize the treatment.
