Chemotherapy side effects refer to the negative effects that can occur as a result of receiving chemotherapy treatment for cancer. These side effects can vary greatly depending on the specific type of chemotherapy drugs being used, the dosage, and the individual's overall health. Common side effects of chemotherapy may include nausea and vomiting, hair loss, fatigue, loss of appetite, and increased susceptibility to infections. Other potential side effects may include diarrhea, constipation, nerve damage, and increased risk of developing other health conditions such as heart problems or infertility. Management of chemotherapy side effects typically involves a combination of medication, lifestyle changes, and supportive care to help alleviate symptoms and improve quality of life for patients undergoing cancer treatment.
