Dietary management is a crucial part of recovery after oncological surgery. Understanding the changes your body is going through and adjusting your diet can help manage symptoms, promote healing, and improve your overall quality of life.

Undergoing surgery for cancer is a significant event that can impact various aspects of your life, including your diet.

How you eat and digest food may change, and you may need to adjust your eating habits to manage symptoms and promote healing.

Your diet will need to change after specific surgical procedures, including managing a chyle leak, esophagectomy, gastrectomy, and Whipple procedure.

Always consult your healthcare team, including your dietitian, to ensure your dietary plan meets your needs.

Dietary Management of Chyle Leak

Chyle is a milky fluid your intestines produce in response to dietary fat intake. A chyle leak can occur after surgery, leading to the need for a very low-fat diet to allow the leak to heal. The goal is to consume as little fat as possible.

Limit your total fat intake to no more than 25 grams daily, spread throughout the day.

Protein intake is crucial, and you may need to use nutrition supplements or protein powders to meet your protein needs. This diet is meant for short-term use and should be followed for 2-3 weeks before consulting a Registered Dietitian. (unsure about this fact)

Dietary Management Post-Esophagectomy

An esophagectomy is a surgical procedure to remove all or part of the esophagus. After this surgery, it is common to have some problems eating for a few months.

Your diet plan will progress through different stages, including clear liquids, full liquids, and a soft solid diet. Your surgeon and dietitian will advise you on when you can move to the next stage based on your recovery rate and how well you can tolerate food.

Dietary Management Post-Gastrectomy

A gastrectomy is the surgical removal of all or part of your stomach. After your gastrectomy, you may experience nausea, early satiety, diarrhea, and weight loss.

To manage these symptoms, eat small, frequent meals and snacks, include a good source of protein with each meal or snack, and consume dietary fats as tolerated.

Dumping Syndrome and Lactose Intolerance Post-Gastrectomy

Dumping Syndrome occurs when food or fluids move too quickly through your digestive system, often resulting in nausea, dizziness, lightheadedness, and diarrhea.

To prevent dumping syndrome, eat 5-6 small meals per day, eat protein at every meal/snack, limit carbohydrates, and eat more soluble fiber.

Some people may also develop lactose intolerance after a gastrectomy, leading to symptoms like gas, bloating, and diarrhea after consuming dairy products.

Dietary Management Post-Pancreaticoduodenectomy (Whipple Procedure)

A Whipple procedure involves the removal of part of the pancreas along with the gallbladder, common bile duct, part of the upper small intestine, and a portion of the stomach.

After surgery, you may experience complications such as fat malabsorption, early feelings of fullness, delayed gastric emptying, hyperglycemia, and weight loss.

Your diet will progress from clear liquids to full liquids and then to regular foods once you tolerate full liquids without any problem.
