Biochemistry Biochemical tests can be used in conjunction with clinical history , examination, comorbidities and drug history . Albumin, C-reactive protein and white cell counts can be markers of infection or inflammation, which can compromise nutritional stat...

Clinical evaluation Clinical assessment of nutritional status should begin by consideration of any important symptoms that may suggest malnutrition. Upper abdominal symptoms such as nausea and vomiting, early satiety , dysphagia, reflux or bloating as well as...

EFFECTS OF INTESTINAL RESECTION ON FLUID AND NUTRIENT ABSORPTION The main role of the intestine is the absorption of fluid, nutrients and electrolytes, and as such it has a large capacity for adaptation to the loss of intestinal length by increasing the abso...
