Notice the signals
Pre-treatment nutrition should identify unintended weight loss, appetite loss, poor absorption, iron deficiency, low hemoglobin levels, and digestive difficulties. Weight loss above 5 percent over three months is a recognized marker of clinical malnutrition and can be associated with delayed healing.
Stable calorie intake and adequate protein help limit a catabolic state before treatment. A registered dietitian can help a patient interpret changing appetite, energy expenditure, and body-weight trends without relying on restrictive advice.
