One tablet of Metformin Hydrochloride per day does not usually result in weight loss. Metformin hydrochloride can reduce hepatic glucose production, inhibit the intestinal absorption of glucose, increase the uptake and utilization of glucose in peripheral tissues, thus improving insulin sensitivity, usually used for the treatment of type 2 diabetes mellitus that is ineffective in controlling blood glucose by simple diet and physical exercise, and generally not used for weight loss. When there is a need for weight loss, you can first start with diet control and physical exercise to reduce the intake of sugary substances, and exercise appropriately to increase the basal metabolic rate, promote fat consumption, and reduce fat hoarding. If the effect of diet control and physical exercise is not obvious, you can go to a professional medical institution for medical treatment under the guidance of a physician. It is recommended to use drugs strictly under the guidance of a physician, and not to take drugs to lose weight privately.
