Low fat mass in dialysis patients most clearly indicates what?

• A. High energy stores and strong coping with stress
• B. Low body stores of energy and poor coping with catabolic stress
• C. Adequate energy reserves with good recovery
• D. Excess fat storage that is beneficial under stress

Answer: (B)

Low fat mass reflects depleted energy reserves. In dialysis patients, catabolic stress from inflammation, the treatment itself, and illness raises energy needs. When fat stores are low, there are fewer substrates available to fuel metabolism during stress, leading to impaired recovery and poorer outcomes. This is why low fat mass most clearly indicates low body stores of energy and poor coping with catabolic stress. The other statements imply adequate or excessive energy reserves, which don’t fit the situation of a catabolic state and malnutrition risk seen with low fat mass.
