Preparing Your Body for Surgery

Many people may need surgery during their lives. For more major procedures, your body works hard to recover and may need extra support to heal properly.

If you're preparing for surgery, one thing that may help is supporting your body by boosting your energy and nutrient intake, if needed. 1,2

Fresubin explains how nutrition and surgery are linked: nutritional status matters as a better nutritional status is linked to better recovery; weight loss is common as illness and surgery can affect weight and muscle mass; and recovery support  through improving intake before surgery may help support recovery.

How Nutrition Support Helps Preparation

Taking oral nutritional supplements (ONS) before surgery can help provide your body with energy, protein and micronutrients when regular food alone isn't enough. ONS are available in different formats, flavours and textures that can fit into your everyday life. 

They are a key part of your pre- and post-operative care, as malnutrition can be a risk both before and after surgery. Taking ONS as part of a wider programme of support can improve your post-operative outcomes and quality of life. 1,2,3,5

What is prehabilitation? Fresubin explains that prehabilitation includes nutrition support, physical activity, stress or anxiety reduction and lifestyle changes.
