Metformin as the world’s number one diabetes drug, in recent years has been crowned as a “miracle drug”, was found to have “weight loss”, “lowering sugar”, ” Anti-aging”, “extend life” and other magical effects, and many patients in the process of taking metformin, but also found that it has a certain weight loss effect, taking metformin for a period of time, there will be a certain degree of weight loss, so metformin as a weight loss drug to use is really good? Generally speaking, BMI (Body Mass Index, also known as Body Mass Index, BodyMassIndex, BMI for short) is greater than 25 is overweight, more than 28 is obese. For this part of the people, metformin weight loss does have a certain effect, but for people who are already standard weight, there is no need to carry out drug weight loss, otherwise it will bring adverse effects, such as nutritional deficiencies, decreased resistance, abnormalities in the nervous system and other symptoms. For the weight loss effect of metformin, it is too weak and inaccurate in people who do not have diabetes, whose BMI does not reach obesity, and who do not have insulin resistance, and it is not recommended for use because of some side effects when taken, and the FDA has not approved it for use as a weight loss drug. Metformin only has a relatively mild weight loss effect for some specific groups, such as type 2 diabetes, polycystic ovary syndrome, and patients with a BMI of 28 or more. In short, for people who just look slightly fat, the most practical way to lose weight is still the same three golden rules that say the same thing: Watch your mouth! Open your legs! Drink more water!
