Liquid Diet: Pre-Requisite For Nissen Surgery

what is the liquid diet before nissen surgery

Nissen fundoplication surgery is a procedure used to correct GERD or repair a hernia. After the surgery, patients must follow a specific diet to aid their recovery and avoid complications. This includes a liquid diet in the initial stages post-operation. The liquid diet helps to manage swelling and prevent irritation to the surgery site, which can make it difficult for food to pass through the digestive tract. Patients are advised to consume clear liquids for a few days, followed by a full liquid diet, and then a soft diet before introducing regular foods.

Clear liquid diet: Only liquids you can see through

A clear liquid diet is typically followed for about 2 days after Nissen fundoplication or hiatal hernia surgery. This diet includes only liquids that one can see through. Clear liquids are the easiest for the body to digest.

The clear liquid diet is also followed for 48 hours before surgery, during which patients are advised not to consume solid food or liquids that cannot be seen through. This is because the surgery cannot be performed with food in the oesophagus.

During the clear liquid diet, patients are advised to drink 8 to 10 cups of liquids per day, if possible. Recommended liquids include water, juices (such as prune juice), soups, and ice cream shakes. It is important to avoid liquids with caffeine, such as coffee and soda, as they can cause dehydration. Ginger tea, flat ginger ale, and saltine crackers softened with broth or another liquid can help with nausea.

It is also important to note that vomiting can weaken or undo the repair from surgery, so anti-nausea medication may be prescribed. If swallowing is difficult, patients are advised to drink warm liquids and contact their surgeon.

The clear liquid diet is followed by a full liquid diet, which includes all the liquids from the clear liquid diet, plus liquids that are thicker or opaque. This is followed by the Nissen soft diet, which includes all the liquids from the full liquid diet, plus physically soft foods.

Full liquid diet: Thicker liquids

A full liquid diet is made up of fluids and foods that are normally liquid or turn to liquid at room or body temperature, like ice cream. It also includes liquids that are thicker or not clear. This diet is nutritionally dense and provides the body with higher levels of protein and carbohydrates. It aims to promote the healing of the digestive tract, which includes everything from the mouth and throat to the colon and rectum.

A full liquid diet is often recommended after Nissen surgery. Nissen fundoplication is a procedure for treating a hiatal hernia. Following the surgery, the area where the oesophagus joins the stomach will be swollen, making it harder for food to move through the digestive tract. To help manage this, patients are advised to follow a liquid diet.

A full liquid diet includes liquids such as water, milk, and fruit or vegetable juice without pulp, like grape or tomato juice. It also includes strained soups, ice cream, milkshakes, and nutritional shakes. Patients can also consume foods that turn into liquids when eaten, such as yoghurt, pudding, and oatmeal prepared to a thin consistency.

It is important to follow this diet exactly to avoid complications with surgery or medical conditions. It is also important to note that a full liquid diet does not provide enough fibre, and patients may not get all the required vitamins and minerals. Therefore, supplements may be recommended by healthcare providers.

Nissen soft diet: Soft foods that require less chewing

A Nissen soft diet is usually followed for about two weeks after Nissen fundoplication or hiatal hernia surgery. This diet includes all liquids, plus physically soft foods that require less chewing and are easy to swallow. This is important because the area where your oesophagus joins your stomach will be swollen, making it harder for food to pass through.

Soft foods that require less chewing include:

  • Smoothies
  • Yogurt
  • Puddings
  • Porridge
  • Scrambled eggs
  • Mashed potatoes
  • Soft-cooked oatmeal
  • Fluffy, soft rice
  • Soft-cooked potatoes with sauce or gravy
  • Tofu cubes in marinara sauce or peanut butter sauce
  • Cottage cheese
  • Beans
  • Soups, especially brothy, drinkable soups

It is important to note that everyone's tolerance for food is different, and you should always follow the advice of your doctor.

Avoid caffeine and carbonated drinks

Nissen fundoplication surgery is a procedure that involves wrapping the top of the stomach around the bottom of the oesophagus. This can cause swelling in the area where the oesophagus joins the stomach, making it harder for food to move through the digestive tract. To prevent further swelling and promote healing, it is important to follow a liquid diet before progressing to soft, easy-to-swallow foods.

Caffeine and carbonated drinks should be avoided before and after Nissen surgery. Caffeine can cause dehydration by pulling fluid out of the body. Dehydration can further complicate the constipation that often occurs after this type of surgery due to prescription pain medications. Carbonated drinks, on the other hand, can cause unusual complications, as evidenced by a case study from the University of Adelaide Department of Surgery, Royal Adelaide Hospital, South Australia.

It is recommended that you avoid caffeine by refraining from drinking coffee and soda. Instead, aim to drink 8 to 10 cups of liquids daily, choosing liquids such as water, juices (e.g., prune juice), soups, and ice cream shakes. You can also opt for decaffeinated coffee or tea, but be mindful of the amount of caffeine you consume.

Regarding carbonated beverages, it is best to avoid them for at least 3 weeks after surgery. If you wish to consume them after this period, it is advisable to pour them into a glass first to allow the carbonation to escape.

By following these guidelines and avoiding caffeine and carbonated drinks, you can aid your recovery and reduce the risk of complications after Nissen fundoplication surgery.

No bread, meat, or gummy foods

Following Nissen fundoplication or hiatal hernia surgery, patients are typically placed on a clear liquid diet for about 2 days, followed by a full liquid diet for approximately 3 days, and then a Nissen soft diet for around 2 weeks. This gradual progression helps manage the swelling in the area where the oesophagus joins the stomach, making it easier for food to pass through.

During the Nissen soft diet phase, it is important to avoid bread, meat, and gummy foods. Bread and other dry bread products, such as crackers and baked goods, can swell with saliva and liquids, potentially forming a blockage in the oesophagus. Meat, especially large or tough pieces, can be challenging to pass through the oesophagus and into the stomach. Patients are advised to introduce meats last and in moderation, ensuring they are trimmed of fat and cooked to be easily breakable with a fork.

Gummy foods, such as green bananas and peanut butter, are also to be avoided as they can be difficult to swallow. Patients should opt for soft, moist, and well-cooked foods that can be easily chewed and broken down. This includes foods like soft-cooked oatmeal, finely chopped pasta, fluffy rice, and soft-cooked vegetables.

It is important to note that everyone's tolerance for food is different, and a patient's doctor will guide them in advancing through the diets at a suitable pace. Additionally, it is recommended to eat slowly, take small bites, and consume several small meals throughout the day instead of large ones to prevent overstretching the stomach, which can cause nausea and pain.
