Optimising your weight prior to surgery will reduce your risk of surgical complications.

A healthy diet consists of a wide variety of foods, the right amount of carbohydrates, fibre, vitamins and minerals, healthy fats and protein.

Nutrition

Good nutrition will promote good wound healing, the ability to get back on your feet quicker, the ability to fight infections more effectively and allow you to maintain your strength.

Obesity and being overweight

Being overweight makes the surgical journey more difficult. Reducing excess weight before surgery might help you to have a smooth recovery after surgery. See your GP for guidance on weight loss before surgery if your Body Mass Index (BMI) is more than 30.

Depending on your weight, it may be appropriate for you to follow a Very Low Energy Diet for a short period of time. Please discuss this option with your GP before starting this on your own.

Malnutrition

Poor nutrition or malnutrition before your surgery may increase the risk of complications and infections after surgery. This could lead to you staying in hospital longer. If you have experienced unplanned weight loss or a recent reduction in your dietary intake it is important you speak to your GP.

If you are unsure about your nutrition status please complete the malnutrition self-screening tool to find out if you are at risk.
