Esophageal Dilation


Esophageal dilation is a procedure to widen a narrow part of your esophagus. Your healthcare provider will use a dilator (inflatable balloon or another tool that expands) to make the area wider. He or she may also do an endoscopy before or during your esophageal dilation. During an endoscopy, your healthcare provider will use a scope to see inside your esophagus.


Call your local emergency number (911 in the US) if:

  • You vomit blood.
  • You have a fast heartbeat, chest pain, or sudden trouble breathing.
  • Your abdomen suddenly becomes tender and hard.

Call your doctor if:

  • You are not able to swallow any food.
  • You have a fever.
  • You feel very full or bloated.
  • You have nausea or are vomiting.
  • You have questions or concerns about your condition or care.


  • Medicines may be given to decrease stomach acid that can irritate your esophagus.
  • Take your medicine as directed. Contact your healthcare provider if you think your medicine is not helping or if you have side effects. Tell him or her if you are allergic to any medicine. Keep a list of the medicines, vitamins, and herbs you take. Include the amounts, and when and why you take them. Bring the list or the pill bottles to follow-up visits. Carry your medicine list with you in case of an emergency.


Your healthcare provider will tell you how long to wait after the procedure before you eat or drink anything. You may need to wait until any numbness in your throat is gone. When it is okay to eat, chew your food well. Eat soft foods if you still have problems swallowing. Soft foods include applesauce, bananas, cooked cereal, cottage cheese, eggs, pudding, and yogurt.

Follow up with your healthcare provider as directed:

Write down your questions so you remember to ask them during your visits.
