Discuss the nutrition-related effects of radiation treatment to the head and neck
Radiation of the head or neck can cause a decrease in salivary secretions, which causes dry mouth (xerostomia) and difficulty in swallowing (dysphagia). It can also cause damage to the taste buds and could also affect taste and smell, causing loss of appetite and weight loss. This reduction in saliva also causes tooth decay and sometimes the loss of teeth. Severe weight loss from not eating enough can also result from radiation therapy. Radiation reduces the amount of absorptive tissue in the small intestine. In addition, it can cause bowel obstruction or diarrhea. ?
