Nausea and vomiting caused by neurological conditions
- Headache: especially migraine, is commonly associated with nausea and vomiting.
- Inner ear: Motion sickness, labyrinthitis, benign positional vertigo, or Meniere's disease
- Increased intracranial pressure: Any illness or injury that increases the pressure within the skull can cause vomiting.
- Brain swelling due to trauma (includes bleeding within the brain)
- Infection (meningitis or encephalitis)
- Tumors (benign or malignant)
- Abnormal electrolyte concentrations in the bloodstream and associated water imbalance
- Concussion, patients with head injuries do not have to have detectable bleeding in the brain or brain swelling to have symptoms of brain irritation, which can include headache, nausea, vomiting, changes in vision, confusion, difficulty concentrating, and difficulty sleeping.
- Noxious stimulae: Certain smells or sounds can cause nausea and vomiting that originates in the brain. Whether it is the pain of a broken bone or the emotional shock of observing an event, vasovagal events can cause significant symptoms. In a vasovagal episode, the vagus nerve (one of the nerves that helps control basic body functions like heart rate, breathing, and blood pressure) is overly stimulated and can cause the heart rate to slow and blood vessels to dilate. This decreases the flow of blood to the brain and can cause fainting (syncope).
- Heat related illness: For example heat exhaustion, extreme sunburn, or dehydration
