Difficulty swallowing: safe, comfortable eating
Mouth and throat sores, infections and radiotherapy can make swallowing painful or hard. Sometimes food or drink "goes down the wrong way" and causes coughing. This section covers foods that make swallowing easier and the warning signs.

01Short answer
02Simple explanation
Smooth, moist food.
Small bites, slowly.
Sit upright.
Coughing or choking? Tell us.
03Scientific explanation
Dysphagia: aspiration (food entering the airway) raises pneumonia risk; swallowing assessment and texture-modified diets reduce it.
ESPEN: enough energy and protein matter for preventing weight and muscle loss in people with cancer, and nutritional status should be assessed regularly.
NCI: practical eating tips exist for treatment side effects such as nausea, taste changes and mouth sores.
04What happens in the body?
Textures
Purée, minced and moist, thickened fluids: a specialist chooses the level.

Pain
Pain relief prescribed by your doctor before meals may help.

Dietitian
If you are losing weight, have no appetite or need a special diet, ask to see the hospital dietitian.
Food safety
Food-safety rules for neutropenia (see “Handwashing: the simplest protection” and “Eggs and dairy: safe choices”) apply at every stage.
05Nutrition: four steps
Assess, swap the risky, cook safely, eat regularly.
