Diet and inoperable pancreatic cancer

What is the dietary advice for inoperable pancreatic cancer?

There is some research evidence that maintaining a stable weight can help improve survival and wellbeing in people with inoperable pancreatic cancer. If you have been diagnosed with inoperable pancreatic cancer and are having difficulty maintaining your weight or eating you can request an assessment with a dietitian. At this assessment you can discuss any dietary related symptoms you are experiencing as a result of the pancreatic cancer or treatment. The dietitian can provide advice to help you manage these symptoms and maintain a good diet.

If you have lost weight or developed steatorrhoea (clay coloured oily stools, which are difficult to flush, and have an offensive smell) the functioning of your pancreas may have been affected by the cancer. In particular you may have a blocked or partially blocked pancreatic duct. You may find it helpful to take pancreatic enzyme supplements to aid your digestion and help you absorb nutrients from food. You can ask your dietitian, healthcare team or GP about these supplements.

If you are finding it difficult to eat, try to get the calories and protein you need in a form that you are able to manage. See our diet tips section for tips on a coping with a small appetite. If you have lost your appetite or lost weight the dietitian or your specialist nurse may suggest you try taking a nutritional supplement.  Your healthcare team may also suggest the use of appetite stimulants such as steroids e.g. Dexamethasone or hormonal therapy e.g. megaestrol acetate.

What is cancer cachexia?

Cancer cachexia is common in people with pancreatic cancer. It is a condition that leads to dramatic weight loss, malnutrition, muscle wasting and fatigue. It is caused by metabolic changes that cannot be corrected through eating extra calories. Once the weight has been lost it can be very difficult to put it back on.

Research has suggested that in some people the use of Eicosapentaenoic acid supplements (EPA) can have an effect on weight, appetite and quality of life. Ask your dietitian or GP about these supplements if you have experienced significant weight loss.
