Symptom #2: Nausea
Another thing that can occur quite commonly in people struggling with glioblastoma is nausea. Nausea is a queasy, sickly feeling that most of us are familiar with. It occurs in the abdomen, usually around where the stomach is, and indicates that the body may or may not need to vomit soon.
The nausea associated with glioblastoma can be quite persistent and remain for a long time. Some anti-emetic medications can be useful for helping to reverse the nausea.
