Low basal metabolism may be caused by physiological factors or diseases such as hypothyroidism. The former can be alleviated by adjusting lifestyle, while the latter requires corresponding treatment according to the cause. 1. Physiological factors: prolonged sedentary life or lack of exercise, ageing and other factors may cause a decrease in basal metabolism, which can be improved through appropriate physical exercise, drinking more water and avoiding a sedentary lifestyle. 2. Disease factors: Hypothyroidism can lead to low metabolic syndrome, resulting in a decrease in basal metabolism, which needs to be treated with levothyroxine sodium tablets under the guidance of a doctor to keep thyroid hormones within a reasonable range, so that the decrease in basal metabolism can be alleviated. It is recommended to go to the hospital after eliminating physiological factors when the basal metabolism becomes low.
