Fecal microbiota transplantation (FMT) is a medical procedure that involves transferring stool from a healthy donor into the gastrointestinal tract of a patient. This process aims to restore the balance of beneficial bacteria in the gut, which can be disrupted by factors like antibiotics or infections. FMT is primarily used to treat conditions such as Clostridium difficile infection, which can cause severe diarrhea and other complications. The procedure can be performed in various ways, including through a colonoscopy, enema, or oral capsules. Research has shown that FMT can be effective in improving gut health and alleviating symptoms in patients with certain gastrointestinal disorders. However, it is essential to screen donors carefully to minimize the risk of transmitting infections.
