10 Radiation Therapy Side Effects That Might Surprise You

2. Loss Of Appetite

It is not uncommon for a patient undergoing radiation therapy as part of their treatment to experience loss of appetite. Appetite loss begins during the first few weeks of radiation therapy and may persist after the treatment ends. Patients having radiation therapy close to their neck and head are more likely to experience loss of appetite. This is because the cellular damage inflicted on healthy cells in these regions can result in taste and smell alterations. An individual may feel that many types of food are no longer appealing because they cannot smell or taste properly. Other mechanisms play a role in appetite loss precipitated by radiation therapy. Nausea and vomiting are common occurrences in patients receiving radiation therapy. They can cause individuals to be unable to consume food regularly. Radiation therapy can also damage the tissues responsible for the production of saliva and fluids. This can result in dry mouth, sore mouth, and issues swallowing food.
