Preparing for surgery
Nutrition before and after neurosurgery
Good nutrition heals wounds faster and reduces infection risk. The rules are simple, not restrictive.
In the weeks before surgery, eat normally and well. Focus on adequate protein (fish, chicken, eggs, beans, dairy), plenty of vegetables and fruit, and enough calories to maintain your weight. This is not the time to start a restrictive diet.
If you are underweight or have been eating poorly, we may add a nutritional supplement drink for a few weeks pre-operatively. If you are significantly overweight, modest weight loss over months helps outcomes — but crash dieting immediately before surgery does not.
On the day of surgery, follow the fasting instructions exactly: usually no solid food from midnight and clear fluids allowed up to two hours before anaesthesia. Modern anaesthesia is safer with a shorter clear-fluid fast.
After surgery, start with what you feel like eating — often that is plain toast or fruit initially. Move to a normal balanced diet as your appetite returns. Aim for protein at every meal to support wound healing.
Stay well hydrated, aim for regular gentle activity, and prioritise sleep. These do more for recovery than any specific superfood or supplement.
