What causes nausea?
Nausea can be caused by the cancer itself. It can also be a side effect of some types of chemotherapy, but anti-nausea medicines can often prevent or manage this.
Other causes of nausea include:
- treatment with radiation therapy
- stress or anxiety
- too much or too little of a mineral in the blood, e.g. calcium
- drugs used to control other symptoms, e.g. morphine for pain
- the kidneys not working properly
- an oral thrush infection, sometimes related to chemotherapy
- a bowel blockage (obstruction) or constipation
- increased pressure around the brain as a result of cancer in the brain or cancer affecting the fluid around the spinal cord.
Tips for easing nausea
- Eat small meals as often as you can.
- Eat cold foods, such as sandwiches, salads, stewed fruit or jelly.
- Avoid strong odours and cooking smells.
- Have food or drink that contains ginger, such as ginger ale, ginger tea or ginger cake.
- Use stress-reduction techniques such as meditation or relaxation.
- Talk to your doctor or nurse about anti-nausea drugs or treatments that can help relieve constipation.
