Many patients experience varying degrees of nutritional deficiency throughout their journey — not only due to reduced food intake, but also because of changes in metabolism, inflammation, and increased energy consumption. Understanding these common deficiencies helps patients take a more proactive and personalized approach to nutritional support.
