The primary purpose of dialysis is to remove waste products and excess fluid from the blood. This treatment is essential for individuals whose kidneys are not functioning properly, which can lead to the accumulation of toxins and fluids in the body. Dialysis artificially performs the vital functions of the kidneys, helping to maintain a proper balance of electrolytes, regulate blood pressure, and prevent complications that could arise from kidney failure.

While appetite improvement, diabetes management, and hormone level regulation are important aspects of overall health and may be associated with conditions requiring dialysis, they do not capture the fundamental role of dialysis itself. Dialysis specifically targets the removal of harmful substances that accumulate when the kidneys can no longer perform their filtering function effectively. This makes option C the clear correct choice regarding the primary purpose of dialysis.
