End of Life Nutrition
Food is so important to each of us for many different reasons. Many of us associate food with comfort, memories of childhood, and happiness. So, when our family member can no longer eat, we automatically have negative feelings. We may feel that our loved one is starving or experiencing hunger. It is important to know how our digestive process changes in life-limiting illness, so that we can help our patients, families, and caregivers make informed decisions.
We eat to provide our body with nutrients that supply energy and help keep us healthy. But, in life-limiting illness, nutritional requirements change as our body is in the process of shutting down. We need fewer calories, so our appetite and desire for food decreases. It is very important to remember that a person at the end of life does not get hungry or thirsty in the same way a healthy person does. The decrease in appetite and the loss of thirst are natural processes that allow the body to prepare itself for death. Forcing food and drink can cause uncomfortable symptoms such as bloating, nausea, vomiting, diarrhea, constipation, edema, and/or gastric reflux leading to aspiration.
It is important to allow the patient to determine what, how much, and how often he/she chooses to eat or drink. Never force food and fluids, our bodies will tell us what they need and when they need it.
Artificial Nutrition and Hydration
Nutrition support at the end of life does not reverse or cure a disease. It is important to explain this fact to our patients and their families. Many studies have concluded that the use of feeding tubes/parenteral nutrition in cancer patients have no clinical benefit. Actually, the use of artificial feeding can increase suffering in the terminally ill by increasing nausea, vomiting, bleeding, edema, pulmonary edema, incontinence and infections. The side effects are the same with artificial hydration. Water deprivation increases the body’s production of endogenous opiates that can actually reduce pain. Many studies show that when mouth moisturizing steps are taken (ice chips, lip balm, moistened swabs), uncomfortable dry mouth can be alleviated without the use of artificial hydration.
Our goal is to allow the patient to be the guide. It is important to have a discussion about the patient’s wishes early on in the diagnosis and treatment if possible. Stress to families the importance of having this discussion prior to the dying process. Open and honest communication among the patient, family, and healthcare team can help the patient make the best decision. If the dying process has begun and the patient’s wishes are unknown, the healthcare team should explain the risks and benefits associated with end of life nutrition to the family/caregiver, so they can make the most informed decision.
