NHS Inform says: “Eating problems can be caused by some cancer treatments. These can be temporary but sometimes last longer.
“If you have treatment to your mouth, throat, stomach or intestine, it will take time to return to a regular eating pattern.
“Treatment such as radiotherapy to the head and neck area may cause a dry mouth and difficulty swallowing.
“Chemotherapy and targeted therapies can cause sickness, diarrhoea or constipation, taste changes and soreness to your mouth.”
