What Are the Causes of Malnutrition in Cancer Patients?
Several factors contribute to malnutrition in cancer patients, including:
Cancer-related metabolic changes: Tumors can alter the body's metabolism, leading to increased energy expenditure and nutrient deficiencies. Loss of appetite: Treatments and the cancer itself can cause nausea, vomiting, and a reduced desire to eat. Swallowing difficulties: Some cancers, particularly those affecting the head, neck, or esophagus, can make it challenging to swallow food. Side effects of treatments: Chemotherapy and radiation can cause sores in the mouth, taste changes, and digestive issues, all of which can reduce food intake. Psychological factors: Depression, anxiety, and stress related to the cancer diagnosis can also affect appetite and eating habits.
