Question

Why does chemotherapy cause side effects such as nausea?

Answer 1

Answer :It sets off warning signals in your brain and digestive system. This flips the on switch in a part of your brain called the vomiting center. It puts out chemicals that make you queasy. Chemo can harm your digestive tract, too, which could also lead to nausea.

Explanation:

Such side effects as nose bleeds, bleeding gums, blood in the urine or stool, and unusually heavy menstrual flow, may be experienced by the patient receiving chemotherapy. Nausea and vomiting occur when certain drugs stimulate an area of the brain called the chemoreceptor trigger zone.
