Common Nutrient Losses in Colorectal Cancer Patients
In colorectal cancer, prolonged diarrhea, surgery, poor appetite, and tumor consumption almost always lead to hypoalbuminemia (serum albumin < 3.5 g/dL, often dropping to 2.5–2.8 g/dL in severe cases). Albumin is far more than just a “nutrition marker”—it is the body’s core transport protein. When it stays low for weeks or months, a vicious cycle begins: edema, delayed wound healing, immune collapse, ascites, and even forced treatment breaks.
