Cancer treatments and eating problems
Some cancer treatments can cause eating problems. These can be temporary and improve when you finish treatment. Other problems may last longer.
In the short-term, surgery can slow down your digestion. If you have surgery to the mouth, throat, stomach or intestine, it can take some time for you to return to a more regular eating pattern.
If you’ve had radiotherapy to the head, neck or chest area you may experience eating problems such as taste changes, swallowing difficulties, a dry mouth and a very sore mouth and throat. Radiotherapy to the tummy (abdomen) or pelvic areas can make you feel sick (nauseous), or be sick (vomit), or it can cause diarrhoea.
Common side effects of some chemotherapy treatments can include loss of appetite, taste changes, constipation, diarrhoea, feeling sick or being sick and a sore mouth.
Biological therapies can affect your appetite or your ability to eat. Problems might include taste changes, a dry or sore mouth and feeling sick.
