This diet and sample menu is for people who have recently had Nissen fundoplication surgery to correct GERD — short for gastroesophageal (GAS-trow-ee-soff-uh-GEE-ol) reflux disease — or to repair various types of hernias, such as hiatal hernia and intrathoracic stomach.

This diet may also be useful after other gastrointestinal (GI) surgeries, such as Heller myotomy and achalasia repair.

After Nissen fundoplication surgery, your surgeon will slowly advance your diet through the following stages:

  1. A clear liquid diet, generally for the first few meals.
  2. A full liquid diet for a meal or two.
  3. And, eventually a Nissen soft diet.

Please note: Because each person’s tolerance to food is unique, your doctor will advance your diet depending on how well you progress after surgery.

The diet will help control issues that may occur after GI surgery, such as:

  • Diarrhea
  • Excess gas
  • Swallowing problems

Clear Liquid Diet After Nissen Fundoplication Surgery

The first diet after Nissen fundoplication surgery includes the following clear liquids:

  • Apple juice
  • Cranberry juice
  • Grape juice
  • Chicken and beef broth
  • Flavored gelatin (Jell-O®)
  • Decaf tea and coffee
  • Caffeinated beverages (based on tolerance)
  • Popsicles
  • Italian ice

Note: You’ll need to avoid carbonated drinks (sodas) for the first six to eight weeks after surgery. After this time, you can try them again in small amounts.

Full Liquid Diet After Nissen Fundoplication Surgery

The full liquid diet contains anything on the clear liquid diet, plus:

  • Milk, soy, rice, and almond (no chocolate)
  • Cream of wheat, cream of rice, grits
  • Strained creamed soups (no tomato or broccoli)
  • Blended, custard style, or whipped yogurt (plain or vanilla only)
  • Vanilla and strawberry-flavored ice cream
  • Sherbet
  • Vanilla and butterscotch pudding (no chocolate or coconut)
  • Nutritional drinks including Ensure®, Boost®, Carnation Instant Breakfast® (no chocolate-flavored)

Note: Dairy products — such as milk, ice cream, and pudding — may cause diarrhea in some people just after GI surgery. You may need to avoid milk products. If so, substitute them with lactose-free beverages such as soy, rice, Lactaid®, or almond milks.

Nissen Soft Diet Tips and Foods to Choose

Tips for keeping your stomach from stretching and avoiding gas after GI surgery

  • Eat small, frequent meals (six to eight per day). This will help you consume the majority of the nutrients you need without causing your stomach to feel full or distended.
  • Eat very slowly. Take small bites and chew your food well to help aid in swallowing and digestion.
  • Sit upright while eating and stay upright for 30 minutes after each meal. Gravity can help food move through your digestive tract. Do not lie down after eating. Sit upright for 2 hours after your last meal or snack of the day.
  • Avoid sticky, gummy foods such as bananas. These types of foods can be hard to swallow.
  • Eat desserts and sweets at the end of your meal to avoid “dumping syndrome.” This describes the rapid emptying of foods from the stomach to the small intestine. Sweets move more rapidly and dump quickly into the intestines. This can cause symptoms of nausea, weakness, cold sweats, cramps, diarrhea, and dizzy spells.
  • Drinking large amounts of fluids with meals can stretch your stomach. You may drink fluids between meals as often as you like, but limit fluids to 1/2 cup (4 fluid ounces) with meals and one cup (8 fluid ounces) with snacks.
  • Avoid drinking through a straw and chewing gum or tobacco. These actions cause you to swallow air, which produces excess gas in your stomach. Chew with your mouth closed.
  • Avoid any foods that cause stomach gas and distention. These include many raw vegetables, dried beans and peas, and any food from the cabbage family.
