Which is a common side effect of radiation therapy?

Hair loss is indeed a common side effect of radiation therapy, particularly when the treatment is directed at areas of the body where hair follicles are located, such as the head or neck. This occurs because radiation can damage the rapidly dividing cells in hair follicles, leading to hair loss in the treated area. The degree of hair loss can vary depending on the dose and type of radiation, as well as the individual’s overall health and hair type.

While diarrhea is a potential side effect related to radiation, it is more commonly associated with radiation treatment directed at the abdomen or pelvis rather than being a general side effect. Weight gain is not a typical reaction to radiation therapy; rather, some patients may experience weight loss due to factors like nausea, changes in appetite, or metabolic changes during treatment. Increased energy is also not a known side effect of radiation therapy, as many patients report fatigue as a result of their treatment. Understanding the specific side effects helps in managing patient care and setting realistic expectations throughout the radiation therapy process.
