Some people with symptoms or side effects of treatment can have difficulty eating. Problems like a sore mouth, diarrhoea, constipation, tiredness or feeling sick can affect how well they eat. They may also find chewing or swallowing difficult. Cancer can also change the way the body uses food, so they may lose weight even if they are eating normally.
If the person you are looking after is having trouble eating, it may help to ask the health and social care professionals in charge of their care for advice. You can ask the GP or district nurse, or ask to speak to a dietitian. Dietitians give specialist advice to people who have eating problems or who struggle to maintain a healthy weight. They may give you a supply of supplements or nutritional drinks.
