The above answers don't know what liraglutide is. Liraglutide is an insulin substitute produced by Novo Nordisk in Denmark for the treatment of type 2 diabetes, which has related side effects. The instructions have been clearly stated, but there are new literature reports that the experiment of oral liraglutide in rats transplanted with human "β" cells has indeed recovered in a short time. However, long-term use (memory is not particularly clear after more than 36 months) will accelerate the apoptosis of "β" cells, resulting in complete loss of islet function. Short-term use has obvious weight loss effect and islet function can be restored. It is suggested that if it is used to lose weight, the course of treatment should be controlled within three months, which should be relatively safe. This drug is a widely used weight loss product in clinic, which is relatively safe. After all, it is a new drug, and the obvious side effects have not been fully highlighted. But it is definitely much better than health care products. As for safety, health care products do not need any cell, animal or human experiments, and clinical drugs must pass these experiments, so the credibility is still very high.
