The workshop covers acute kidney injury (AKI), focusing on its clinical presentation, diagnosis, classification, and evidence-based nutritional management. It explains AKI as a sudden decline in kidney function that leads to fluid overload, waste accumulation, and electrolyte imbalances, commonly seen in hospital and ICU settings. The session highlights KDIGO diagnostic criteria and distinguishes between pre-renal, intrinsic, and post-renal causes. Overall, it emphasizes early medical intervention along with individualized nutrition therapy, including appropriate energy, protein, and fluid management to support recovery and prevent complications.
