Symptoms of low basal metabolic rate

If the basal metabolic rate is low, the body's own energy supply will be insufficient, and the person will show signs of weakness, dizziness, and decreased intelligence. Insufficient energy supply will also affect normal work and life. Memory will also decline, and the person will always be distracted when doing things, as if he or she has Alzheimer's disease. It may also cause drowsiness, cold body, weakness and night sweats.

Basal metabolic rate (BMR) refers to the energy metabolism rate of the human body when it is awake and extremely quiet, and is not affected by muscle activity, ambient temperature, food, mental stress, etc.

The energy metabolism rate of the human body when it is awake and extremely quiet, and is not affected by factors such as mental stress, muscle activity, food and ambient temperature. To measure the basal metabolic rate, you need to lie down and rest for half an hour in the early morning before breakfast (but stay awake), maintain the room temperature at around 20℃, and measure it using an indirect calorimetry instrument. The unit of basal metabolic rate is KJ/m2/h (kilojoules per square meter per hour), which is the kilojoules of heat dissipated per square meter of body surface per hour. The basal metabolic rate is very close among normal people of the same gender, weight and age group, and the metabolic rate of more than 90% of them does not differ from the average value by more than 15%. Therefore, this percentage is used as the limit of normal value in clinical practice. Exceeding this limit is considered a basal metabolic abnormality.

often. For example, patients with hyperthyroidism may have a basal metabolic rate 20 to 80% higher than normal, while those with hypothyroidism may have a basal metabolic rate 20 to 40% lower than normal. The determination of basal metabolic rate is a simple and effective method for clinically diagnosing thyroid diseases. Other factors, such as insufficient secretion of hormones from the adrenal cortex and anterior pituitary, may also manifest as a decrease in basal metabolic rate. When body temperature rises, the basal metabolic rate also increases. Generally, for every 1°C increase in body temperature, the basal metabolic rate increases by 13%. When people are hungry or malnourished for a long time, their basal metabolism will decrease. In addition, measuring the basal metabolic rate and the energy metabolism rate at different activity intensities is also the basis for rationally formulating nutritional standards and arranging people's meals.

The main manifestation is a slowing of the whole body metabolic rate. Symptoms of low basal metabolic rate: fatigue, dull sensation, slow movements, intellectual impairment, severe memory loss, drowsiness, inattention, chillness, fear of cold, dry and falling hair, slow beard growth in men, no sweat and body temperature below normal.
