Yes, small intestinal bacterial overgrowth (SIBO) is curable in most cases, but requires a structured and individualized treatment concept. Successful treatment consists not only of eliminating the excessive bacteria, but also of investigating the causes and providing long-term support for intestinal function. Particularly important are the promotion of intestinal motility, the restoration of healthy intestinal flora and a balanced diet. Although relapses are possible, they can be significantly reduced through preventative measures. If the therapy is implemented consistently, the prognosis is very good.
