Nutrition impact symptoms

aka NIS, Eating-related symptoms

The side-effects of cancer and its treatment that stop people eating: nausea, mouth soreness, taste changes, difficulty swallowing, early fullness, constipation, pain and low mood. Treating them is often the most effective nutrition intervention.

Nutrition impact symptoms explain much of the weight loss in head and neck, oesophageal, gastric and pancreatic cancer and during chemotherapy, and unlike cachexia they are reversible with targeted treatment (antiemetics, mouthcare, dysphagia diets, pancreatic enzyme replacement, laxatives, analgesia). Systematic screening with the PG-SGA symptom checklist or patient-reported outcome tools identifies them earlier than clinician assessment. Pancreatic exocrine insufficiency, present in most pancreatic cancer patients, is under-treated.
