Making changes in one's lifestyle may be helpful in relieving the symptoms and may improve the effectiveness of anti-Nausea and anti-Vomiting drugs.

Nutrition

Nausea and Vomiting caused by cancer treatment can affect the amount and kinds of food one can eat. The following points may, therefore, help to control them:

  • Eating before the treatments.
  • Rinsing the mouth before and after eating.
  • Eating foods that are bland, soft, and easy-to-digest, rather than heavy meals.

  •    Eating small meals several times a day.
  • Eating dry foods such as crackers, bread sticks, or toast throughout the day.
    • Sipping fluids throughout the day.

  • Sucking on hard candies such as peppermints or lemon.
    • Staying away from foods that are likely to cause Nausea, e.g. spicy, greasy and foods with strong odours.
    •   Sitting up or lying with the upper body raised for one hour after eating.

  • Avoiding eating in a room that has cooking odours or that is very warm; the living space should be maintained at a comfortable temperature, with exposure to plenty of fresh air.

  • Limiting the use of caffeine, including colas and other caffeinated soft drinks/preparations, coffee and tea.
  • Optimizing oral hygiene, especially after episodes of vomiting. Rinse mouth with a mixture of 1/2 tsp baking soda and 1/2 tsp salt in two cups of water.

Environmental Modification

  • Eliminating strong smells.
  • Wearing loose clothing.
