Study Notes
Effects of Cancer Treatment on Nutrition
- Decreased sense of taste and smell due to cancer treatment
- Metabolic abnormalities, including cachexia, and hypoproteinemia
- Fatigue, fever, and bone pain as side effects of cancer treatment
Effects of Chemotherapy and Radiotherapy on Nutrition
- Decreased food intake and impaired absorption of nutrients
- Metabolic requirements increase during chemotherapy and radiotherapy
- Steroid-induced increase in blood sugar levels
- Filgrastim (G-CSF) and Sargramostim (GM-CSF) treatments for neutropenia and anemia
Effects of Radiotherapy on Nutrition
- Head and neck region: xerostomia, mucosal atrophy, dysphagia, and odynophagia
- Thorax region: dysphagia, esophageal fibrosis, stenosis, and necrosis
- Abdomen and pelvis: nausea, vomiting, diarrhea, and changes in bowel function
- Surgical effects: dumping syndrome, gastroparesis, and fat malabsorption
Nutritional Outcomes in Radical Resection of Systemic Organs
- Colorectal resection: diarrhea, dehydration, and vitamin-mineral malabsorption
- Gynecological resection: early saturation, bloating, and cramping
- Brain resection: nausea and vomiting, and hyperglycemia if taking corticosteroids
- Liver resection: transient hypoalbuminemia
- Jejunum resection: reduced absorption of glucose, fats, protein, and folic acid
- Ileum resection: malabsorption of vitamin B12, fats, and bile salts
- Small intestine resection: malabsorption of vitamin B12, fats, glucose, protein, and folic acid
- Pancreas resection: malabsorption and diabetes
- Colon resection: hydroelectrolyte loss
Aims of Medical Nutrition Therapy
- Preventing malnutrition
- Reducing nutrition-related side effects
- Helping individuals reach and maintain a healthy weight
