Clinical dieticians provide evidence-based therapeutic nutrition interventions for patients with complex medical conditions such as diabetes, renal disease, cardiovascular disorders, gastrointestinal conditions, and critical illness. They analyse medical histories, laboratory markers, nutritional deficiencies, and metabolic responses to create clinical diet plans. Working in hospitals, ICUs, specialty clinics, and rehabilitation centres, they collaborate with physicians, nurses, and allied health professionals to optimise treatment outcomes. Their role is expanding globally due to rising chronic disease burden, ageing populations, and demand for personalised nutrition therapy. Expertise in clinical assessment, documentation, and interdisciplinary coordination is essential.
