Weight loss interventions are proven to improve glycemic control and cardiovascular risk factors, and successful weight loss is associated with improved albuminuria in patients with preexisting chronic kidney disease.

Understanding the dynamics of the gut-kidney axis provides new insights into potential therapeutic strategies to mitigate CKD progression. Diet is the primary driver of gut microbiota composition. Therefore, an approach emphasizing healthy nutritional patterns is recommended for improving overall health, cardiovascular disease, and profoundly altered metabolic patterns in CKD patients. Dietary modifications have been explored as therapeutic strategies targeting the microbiome to improve outcomes in CKD. An emerging therapeutic target is the production of dysmetabolites by the gut microbiota, which may help alleviate uremic and cardiovascular toxicity. Additionally, future research should broaden the scope to include other microorganisms, such as fungi, archaea, and viruses. This expanded focus will enable a more comprehensive understanding of the gut-kidney axis and pave the way for more personalized and effective treatment strategies for CKD patients.
