Diet After Nissen Fundoplication Surgery

After surgery, you will have swelling where the esophagus connects to the stomach. The swelling will make it hard for you to swallow or burp because the opening will be about the size of a straw. The feeling of tightness and trouble swallowing will go away over the next 3 to 12 weeks. Follow these diet guidelines to prevent problems from surgery.

Eating and drinking are key to getting enough calories and other nutrients to help you heal. To protect the area, prevent more swelling and to promote healing, follow a diet of soft, easy-to-swallow and easily chewed foods for at least 4 to 6 weeks after surgery. Follow this diet to prevent problems that could occur from swallowing food chunks that are too large or too rough to pass through your swollen tube. This diet will also help to control nausea, extra gas, diarrhea or problems swallowing.

Avoid stretching your stomach

Because the top of your stomach was wrapped around the bottom of your esophagus, your stomach will not be able to hold large amounts of food. Over-stretching your stomach could put stress on the site and cause you to have nausea, retching or pain.

  • Eat 5 or 6 small meals each day instead of 3 large meals.
  • Eat slowly and eat in a calm and relaxing placeDrink at least 6 to 8 cups of liquid each day, but limit your liquids to 4oz or 1/2 cup with meals and 8oz or 1 cup with snacks. Drink the rest of your liquids to between meals and snacks.
  • Drink at least 6 to 8 cups of liquid each day, but limit your liquids to 4oz or 1/2 cup with meals and 8oz or 1 cup with snacks. Drink the rest of your liquids to between meals and snacks.
  • Eat sweet foods and desserts at the end of your meals as these food make digestion occur more quickly.

Avoid problems swallowing

  • Sit upright when eating and for at least one hour after eating
  • Take small bites and chew all of your food to baby food consistency before swallowing. If your food cannot pass through a straw, it cannot be swallowed.
  • Eat only foods that you can tolerate. If you have trouble swallowing or you feel pressure or food getting stuck, stop eating and give the food time to pass. After the food passes, begin to eat again and chew more food and add more liquid to moisten the food. If soft food continues to cause problems, go back to pureed or liquid diet for a few days.
  • Keep food soft, well-cooked and moist. Avoid gummy foods, such as breads, green bananas and peanut butter, that can be hard to swallow.
  • Do not eat dry bread products. These foods can swell with your saliva or other liquids and could form a ball in your esophagus and cause blockage.
  • Do not eat meat for at least the first 2 weeks. No large or tough pieces of meat after that as they can be hard to pass through the esophagus into the stomach.
  • Do not eat raw, crunchy fruits or vegetables. These foods can have sharp edges that could irritate and cause more swelling.

Avoid gas and bloating

  • Avoid liquids that are either hot or very cold as they can cause spasms and pain in the esophagus
  • Avoid talking during meals, drinking from a straw or bottle, and do not chew gum or tobacco.
  • Limit or avoid foods that cause stomach gas or bloating. These may include milk and other dairy products, sugar, broccoli, cauliflower, cabbage, onions, and beans or legumes
  • Avoid carbonated beverages, including beer for at least 3 to 4 weeks. After that, be sure to pour the carbonated drink into a cup or glass to allow some of the fizz or carbonation to escape.
