Nausea and vomiting

What it is

Nausea and vomiting can be symptoms of a glioma, often resulting from raised intracranial pressure (increased pressure inside the skull). They may be worse in the morning and can occur with headache. They can also be side effects of treatment such as chemotherapy or radiation.

Understanding Nausea and vomiting

When a glioma raises the pressure inside the skull — through its mass, surrounding swelling, or blockage of fluid flow — it can stimulate the brain's vomiting centers, causing nausea and vomiting. A classic pattern is vomiting that is worse in the morning (when pressure tends to be higher after lying down overnight) and that may occur with morning headache; sometimes vomiting can occur without much preceding nausea. In children especially, persistent or unexplained vomiting (particularly with morning headaches or other symptoms) can be a sign of a brain tumor and warrants evaluation. Nausea and vomiting can also be caused by glioma treatments, in which case anti-nausea medications and supportive care help. Distinguishing tumor-related from treatment-related causes guides management. Understanding nausea and vomiting in gliomas clarifies these symptoms and their link to raised pressure.

Why it matters

Understanding nausea and vomiting helps patients and families recognize them as possible signs of raised pressure from a glioma — especially morning vomiting with headache — warranting evaluation, while also being manageable treatment side effects.
