Malnutrition and Nutritional Support
Dec 09
Loss of appetite can lead to malnutrition.
Patients undergoing treatment for head and neck cancers are at high risk for malnutrition. The cancer itself, poor diet before diagnosis, and complications from surgery, radiation therapy, and chemotherapy can lead to nutritional shortfalls. Patients can lose the desire to eat due to nausea, vomiting, trouble swallowing, sores in the mouth, or dry mouth. When eating causes discomfort or pain, the patient’s quality of life and nutritional well-being suffer. The following suggestions may help patients with cancer meet their nutritional needs:
- Change the texture of food. Serving food chopped, ground, or blended can reduce the amount of time it needs to stay in the mouth before being swallowed.
- Eat between-meal snacks to add calories and nutrients.
- Choose foods high in calories and protein.
- Take supplements that provide vitamins, minerals, and calories.
Nutritional counseling may be helpful during and after treatment.
Nutritional support may include liquid diets and enteral feedings.
Many patients treated for head and neck cancers who receive radiation therapy alone are able to eat soft foods. As treatment progresses, most patients will include or switch to liquid diets using high-calorie, high-protein nutritional drinks. Some patients may need enteral tube feeding to meet their nutritional needs. Almost all patients who receive chemotherapy and head and/or neck radiation therapy at the same time will require enteral nutritional support within 3 to 4 weeks. Studies show that patients benefit when they begin enteral feedings at the start of treatment, before weight loss occurs.
Normal eating by mouth begins again when treatment is finished and the site that received radiation is healed. The return to normal eating often needs a team approach, including a speech and swallowing therapist to ease the adjustment back to solid foods. Tubefeedings are decreased as a patient’s intake by mouth increases, and are stopped when the patient is able to get enough nutrients by mouth. Although most patients will regain their ability to eat solid foods, many will have lasting complications such as taste
