Chemotherapy is most commonly used to treat cancer. According to the Mayo Clinic, the process of chemotherapy is: "a drug treatment that uses powerful chemicals to kill fast-growing cells in your body." Chemotherapy treatments have several side effects that can lead to dehydration.
Appetite and Vomiting
Chemotherapy can cause a loss of appetite. This loss of appetite is often caused by pain and or sores in the mouth and throat. Vomiting is also a side effect of chemotherapy. The lack of fluids being taken in and digested can cause dehydration.
Diarrhea
Foods and fluids that are taken in during times of chemotherapy can also be quickly expelled by the body. The resulting diarrhea gives much-needed fluids and vitamins little time to reach muscles and organs in the body.
