About Dysphagia

Dysphagia (dis-FAY-jee-uh) is the medical term for pain or trouble when swallowing.

If you have trouble swallowing, it can be hard to eat and drink. Eating and drinking enough will help you heal, maintain your weight, and stay strong through your cancer treatments.

  • Trouble swallowing can happen in 3 different areas:
  • Your oral cavity (mouth, lips, soft palate, tongue, or gums)
  • Your pharynx (throat)
  • Your esophagus (the tube that carries food and liquid from your mouth to your stomach)

The ways you can manage your dysphagia depend on the area(s) affected:

If you have trouble swallowing you can be at a higher risk of:

  • Pneumonia (chest infection)
  • Obstruction (food getting caught in your esophagus)
  • Aspiration (food going down your wind pipe, into your lungs)
  • Malnutrition (lack of nutrients needed for the body to work it’s best)
  • Dehydration (losing more fluid than your body takes in)

Emotions That Come with Trouble Swallowing

Trouble swallowing can make meal times harder or more stressful. Many people who struggle with swallowing can have feelings of anxiety, sadness, fear or anger. These feelings can affect how you enjoy food and your relationship with eating. You might also feel overwhelmed having to manage these side effects at home. It’s normal to feel this way, as these side effects can impact your quality of life. Put simply, dealing with pain and trouble swallowing can be tough.

Ask for help at the first sign of changes to your swallow. This can stop your side effects from getting worse. Sharing your experiences with your healthcare team will let them support you best during your treatment.

Effects of Cancer & Cancer Treatment

Trouble swallowing can be the result of a side effect of cancer treatment or the cancer itself. This can include:

  • A tumour blocking your throat or esophagus
  • A tumour impacting nerves that help control your swallow
  • Side effects from radiation to or near your mouth, throat or esophagus
  • Side effects from systemic treatment (type of cancer treatment that travels through the bloodstream to reach cells all over the body, like: chemotherapy or checkpoint inhibitors)
  • Surgery

Cancer treatments can damage the mucous membranes that line the mouth, throat and esophagus. This can lead to pain or trouble swallowing. These side effects can start any time during your treatment. They may get worse over time. Sometimes side effects can last for weeks (or linger for months) after treatment is finished. Know that everyone is unique. No one can foresee who will get side effects, or how long they will last. The best way to manage pain or problems swallowing is to tell your healthcare team as soon as you notice changes.

When to Take Action

Tips to Manage Trouble Swallowing

  • Sit upright when eating
  • Choose soft or moist foods
  • Cut food into small, bite-sized pieces
  • Completely swallow each bite before taking another
  • Take your time and avoid too many distractions while eating
  • Add gravy, sauces or jams (or any extra moisteners) to foods to make them easier to swallow
  • Accept help from family/friends; if they offer to cook for you, let them. Tell them how to modify food to make it safe for you to swallow
  • Eat slowly and pause between bites. Put your fork/spoon down between bites to help pace yourself naturally
