TREATMENT OF OBESITY BY IMPROVING THE METABOLISM OF OBESE PEOPLE BY FECAL MICROBIOTA TRANSPLANTATION (FMT) AND FECAL CAPSULES (SYSTEMATIC REVIEW)

Over the past half-century, the prevalence of obesity and related metabolic disorders such as fat disorders, cardiovascular disease, myocardial infarction and stroke have increased dramatically. Various types of organisms, including bacteria, fungi, protozoan, and viruses, have evolved to live in the human gut, called microbiota. Scientists have found that thin people have a balanced microbiota in their gut that causes them to lose weight, so they use a method called fecal grafting and fecal capsules to treat obesity. The aim of this study is to introduce fecal graft and its capsule in the treatment of drug-resistant obesity.

This article is a systematic review of the study which English and Persian articles are obtained from regular search of Internet resources using logical AND, OR function between keywords in Pub Med, Google scholar databases using English keywords, FMT, obesity, poop capsule, weight loss has been done from 2010-2020. The total search for fecal transplant related resources was 474 articles. Then, by applying the time filter, this number was reduced to 237 articles. In the final stage, by eliminating duplicate articles and examining the relationship of articles with the subject under study, 23 articles were selected as relevant and final sources.

In the treatment of obesity with FMT, the donorchr('39')s stool is transferred to the recipient after screening and necessary tests using various methods such as enema or colonoscopy, and then the recipient gradually loses weight by receiving a balanced microbiota of the donor. Instead of a stool transplant, which is a relatively invasive procedure, stool capsules consisting of the donorchr('39')s dried stool can be used.

Stool transplantation and fecal capsule are an effective method in weight loss of obese people (BMI> 30) with due consideration. Due to the novelty of the treatment method, further studies in this field, especially clinical studies of this method in the treatment of obese people in the country are also recommended.
