Low basal metabolic rate can be caused by excessive dieting, lack of exercise, hypothyroidism, etc. Measures can be taken to improve the basal metabolic rate by adjusting the diet, strengthening exercise and taking medication. 1. Excessive dieting: If you lose weight by excessive dieting, your basal metabolic rate may be low due to low energy intake. This can be alleviated by adjusting the diet, such as paying attention to balanced nutrition and increasing dietary intake in moderation. 2. Lack of exercise: A long-term lack of exercise can lead to a decrease in muscle content and an increase in fat content, which may cause a low basal metabolic rate. The patient can effectively relieve the symptoms by strengthening the exercise and exercising properly. 3. Hypothyroidism: Low basal metabolic rate can be caused by insufficient synthesis and secretion of thyroid hormones by the thyroid gland. It can be treated with oral medication such as levothyroxine sodium tablets. When the patient has a low basal metabolic rate, it is recommended to go to the hospital in time for a detailed examination to find out the cause of the disease, and then follow the doctor’s instructions to use medication to treat the disease, do not use medication privately, so as not to aggravate the condition.
