Constipation is common complaint during cancer therapies. This is usually brought on by the general disruption of the daily routine resulting from extra travelling, stays in hospital or waiting in hospital waiting rooms. 

Other general contributory factors include: 

Symptoms of constipation We are all familiar with the symptoms of constipation which most commonly include an uncomfortable feeling in the back passage, bloating and abdominal cramps. There are many other symptoms which are not so immediately obvious. A recent survey of patients with regular constipation reported the following symptoms:


Despite the frequency of this complaint, it is often looked and only addressed when it becomes a significant problem. With some logical foresight however constipation can often be prevented. For example if anti-sickness drugs such as ondansetron are give with chemotherapy consider changing the diet the day before chemotherapy (especially if constipation has been a problem in previous cycles). Try eating three or four dried prunes (or something equivalent if you don’t like prunes) the night before and the morning of chemotherapy. Immediately after chemotherapy it is more difficult to modify diet as there is usually some impairment of appetite but not to worry the fibre will already be in the system. Another good manoeuvre is also to try and go for a brief walk in the fresh air in the evening after the chemotherapy – this may seem alien but not only will it help prevent constipation but it will help the nausea.  Painkiller such a codeine also commonly cause constipation; consider changing the diet before the stools harden rather than wait for the uncomfortable circle of complaint setting it and self perpetuating.
