Pancreatic Cancer
The pancreas is an important organ that produces the digestive juices that help break down food and the hormones that help control blood sugar levels. Early warning symptoms of pancreatic cancer are either vague or non-existent and it is therefore hard to catch it in the early stages. Pancreatic cancer spreads quickly, is often found in the later stages and can be hard to treat. Symptoms may include yellowing of the skin and eyes, pain in the abdomen and back, weight loss and fatigue. Possible treatments include surgery, radiation and chemotherapy.
Any form of cancer and its treatment place extra energy demands on the body, greatly increasing nutrient and energy requirements. Early weight loss, even pre-diagnosis, contributes to fatigue and delayed recovery. Problems with eating and digestion compound these issues and lead to further weight loss. In addition, treatments such as surgery, chemo and radiotherapy increase nutritional needs whilst also hindering intake due to side effects such as nausea, vomiting, loss of appetite and taste changes.
A dietitian should be consulted to help ensure nutritional and kilojoule needs are being met pre and post-treatment for optimal recovery and to enhance quality of life. They can suggest practical solutions to barriers to eating, such as eating small, frequent meals and choosing foods that are easy to chew, swallow, digest, and absorb. Liquid supplements are likely to be recommended due to the very high caloric demands placed on the body.
If the pancreas is not functioning optimally a number of vital bodily functions will be affected. The pancreas may not be able to adequately produce insulin which regulates blood glucose levels. If this is the case, education on diabetic management is required. A diabetes educator will educate on insulin administration, whilst a dietitian will educate on a healthy diet and specifically focus on carbohydrate quality and quantity. The pancreas may also be inefficient at producing the pancreatic enzymes which help digest particular foods such as fats and proteins. Pancreatic enzymes can be supplemented to counteract any malabsorption of fat or protein. Symptoms of malabsorption include bloating, indigestion, diarrhoea, constipation, foul smelling stools, and muscle weakness. Pancreatic enzymes must be taken with all meals and snacks and the dosage will differ for individuals and depend on what is being eaten. A dietitian is vital in educating patients on how to use pancreatic enzymes efficiently.
