Information & support Download resources Blocked Bowel . Download fact sheet . A blocked bowel (also known as bowel obstruction) is a possible complication of ovarian cancer. This can happen for several reasons. As the tumour grows it can press on the bowel, causing a blockage. Sticky tissue called adhesions can form after surgery and can stop food passing down the gut. If you have experienced or are at risk of a blocked bowel, you may be advised to eat less fibre. This is known as a fibre-restricted diet or a low residue diet. This sort of diet may not be suitable for you. If you are not sure whether this applies to you, please check with your doctor or specialist cancer dietitian. . Why should I eat less fibre? Fibre (also called roughage) is the part of food that you do not digest which passes down into the lower part of the gut where harmless bacteria ferment it and produce gas (wind). Eating less fibre will reduce the amount of waste you produce and, as a result, ease symptoms such as bloating and stomach pains. It may also reduce the risk of your bowel becoming blocked. . Will this type of diet work? It is difficult to study the possible benefits of a fibre-restricted diet for a blocked bowel. Most of the evidence to suggest this type of diet is helpful comes from the experience of doctors, nurses and dieticians working with women with ovarian cancer. . What is a fibre-restricted diet? This type of diet includes low-fibre foods and a reduced amount of fruit, vegetables and wholemeal products. Below are examples of foods you should avoid and foods which are allowed. . What about constipation? A fibre-restricted diet still contains some fibre. If you are worried about being constipated, talk to your doctor as you may need laxatives. For our bowels to work properly, it is important to have enough to drink. We normally need about eight to 10 cups of liquid each day. . What about vitamins and minerals? When some foods are limited in your diet, it can be difficult to make sure you get the right amount of vitamins and minerals. It may be necessary to take a multivitamin and mineral supplement. There are lots of supplements available in chemists, health food shops and supermarkets. A dietitian can give you advice about whether you need to take supplements, and they can also recommend which type to buy. . What if the diet is too difficult to follow? As part of a healthy diet, we are all being encouraged to eat more fibre. Like many women who have been diagnosed with ovarian cancer, you may have been eating lots of fruit and vegetables, wholemeal bread and high-fibre breakfast cereals. So, a fibre-restricted diet can be completely different to your normal diet. If you are finding it difficult to follow a fibre restricted diet, ask for a referral to a dietitian who can give you further advice on suitable food choices. . What if I’m losing weight? If your stomach is bloated and uncomfortable, it is often difficult to eat a normal-sized meal. This can eventually lead to you losing weight. It is usually better to have several small meals and snacks during the day. If you have a poor appetite and you lose weight, try to eat foods high in energy such as those containing fat and sugar. Your doctor or dietitian may also recommend nourishing drinks and supplements to help stabilise your weight. These may be available on prescription. . Is a fibre-restricted diet suitable for women with ovarian cancer? This type of diet is not suitable or necessary for all women with ovarian cancer. It is likely only to be a benefit if you have or are at risk of a blocked bowel. If you would like more information on the sources and references for this fact sheet, please call us on 0800 008 7054.
