If the low basal metabolism is caused by disease factors, such as hypothyroidism, patients can take levothyroxine and other medications as prescribed by the doctor to improve basal metabolism; if the low basal metabolism is caused by non-disease factors, the basal metabolism can be increased by increasing the intensity of physical activity or adjusting the intake of the three major nutrients, and other ways to improve the basal metabolism. Specifics need to follow the doctor’s advice. 1. Disease factors: Hypothyroidism is a generalized low metabolic syndrome caused by hypothyroidism or thyroid hormone resistance. Typical hypothyroid patients may show symptoms such as chills, fatigue, swelling of hands and feet, drowsiness, memory loss, etc. Symptoms can be effectively improved by taking drugs such as levothyroxine. 2. Non-disease factors: Increasing activity can effectively improve cardiopulmonary function, promote circulation and metabolism, which can effectively improve the effect of basal metabolism. Dietary increase in protein intake, reduce carbohydrate and fat intake, can effectively improve basal metabolism. It takes time to adjust to the increase in basal metabolism, so consult a medical professional if necessary.
