Swallowing problems

Cancer and its treatments can sometimes cause trouble with swallowing. If you’re having problems swallowing, try eating soft or liquid foods. You may be able to swallow thick fluids more easily than thin liquids. If you’re unable to eat enough regular foods to meet your nutritional needs, drink high-calorie and high-protein liquids.

Your doctor may refer you to a speech therapist. This is an expert health professional who can teach you how to swallow better and how to decrease coughing and choking when you eat and drink.

What to do

  • Follow your speech therapist’s instructions for any special eating techniques.
  • Call your cancer care team right away if you cough or choke while eating, especially if you have developed a fever.
  • Eat small, frequent meals.
  • Use canned liquid nutritional supplements if you’re unable to eat enough food to meet your needs.
  • Chop or puree your food in a blender or food processor.
  • Drink 6 to 8 cups of fluid each day, and thicken the fluid to the consistency that’s easiest for you to swallow.
  • Try these thickening products:

    Use to help soften cakes, cookies, crackers, sandwiches, pureed fruits, and other cold food. Mix 1 tablespoon unflavored gelatin in 2 cups hot liquid until dissolved; pour over food. Allow food to sit until saturated.

    Tapioca, flour, and cornstarch:
    Use to thicken liquids. Note that these must be cooked before using.

    Commercial thickeners:
    Follow label instructions, and use to adjust a liquid’s thickness.

    Pureed vegetables and instant potatoes:
    Use in soups. Note that these change the food’s flavor.

    Baby rice cereal:
    Use to make a very thick product.

  • If thin liquids are recommended for you, try these: coffee, tea, soft drinks, liquid nutritional supplements, Italian ice, sherbet, broth, and thin cream-based soups.
  • If thick liquids are recommended for you, try these: buttermilk, eggnog, milk shakes, yogurt shakes, and ice cream.
