High fibre diet
 
After you have been on a medium fibre diet for a while you may find that you need to increase your fibre intake.

As your symptoms improve and your bowel motions normalise you may be able to start reintroducing some high fibre foods. Do this slowly and add one new food at half a cup at a time so you can identify any foods that cause bowel upset.

Eating Well


Some important points
 
If you experience constipation or any sign of blockage – not opening your bowels for two to three days, please contact your specialist or healthcare professional.
 
You may have reintroduced some of your high fibre foods too quickly and may need to go back onto a medium fibre diet and start more slowly.
 
If you experience extremely loose watery bowel motions and leakage, pain or fever please contact your specialist or healthcare professional.
 
High fibre diets may be suitable for diabetics, please discuss this with your healthcare professional.

Tips for managing your bowel

Write a food diary. Some foods may make your symptoms worse. Everybody is different, therefore only you can tell what aggravates your symptoms. Writing a food diary helps you to identify what foods make your bowel work better or worse.

Eat normally and try to keep your weight stable. This is particularly important if you are undergoing treatment.

If you are losing weight drink some protein drinks in between meals with a milk of your choice, you can add a little psyllium husk or slippery elm powder to make your drink thicker and more fibrous.

Lactose intolerance may persist beyond surgery in some people, a food diary will help you determine this or speak to your health care professional. Lactose is found in dairy products such as milk, cheese, yoghurt and ice cream and some processed and packaged foods.

Make sure you have plenty of water. This is particularly important when you are consuming a higher fibre diet to avoid constipation. Aim for 6-8 cups of water a day, if you like some flavour in water enjoy some sliced fruit in water to infuse some healthy sugars.
 
Introducing a wider range and variety of foods may mean you do not need a multivitamin supplement. Check with your health care professional.

Food choices

Foods may not need to be peeled; nuts, seeds and pips may be added to your diet, write a food diary you if they are not suitable to understand which ones are causing issues. Fruit and vegetables may be able to be consumed raw, steamed and cooked.

Add small amounts - such as one teaspoon of whole nuts, coconuts, seeds, you may be able to eat less tender pieces of meat, chicken and you may start to eat lentils and beans, wholemeal wholegrain and multigrain bread, and dried fruit and fruit with peel.

NOTE: if you experience bowel upset revert to the medium fibre diet again for a few days to settle your bowel

Talk to a health care professional if you are experiencing any soreness internally or externally.

You can add Psyllium husk or Metamucil daily to food or drinks to ensure a well formed and completely evacuated bowel motion. This is a fibre and would need to be introduced slowly to avoid constipation, remembering to increase water intake at the same time.
 
This is a sample menu guide please ensure you read our Modifiable Bowel Cancer Risk Factors on the website to ensure you are eating within the World Cancer Research Fund guidelines to modify bowel cancer risk.
 
You can eat most fruit and vegetables and other lower fibre foods, however, aim to add at least two to three cups of higher fibre foods suggested per day.
