What is a liver reduction diet?
A liver reduction diet is a diet low in calories and carbohydrates. You must only drink liquids for two weeks and not eat any food. It is enough nutrition to keep you well. It is likely you will lose weight but it is not a diet for weight loss.
Why do I need to follow this diet?
Your surgeon has advised you to follow this diet to shrink your liver. This means the surgeon will have safer access to your stomach and reduce the risk of damage to your liver during the operation.
Are there any side effects?
• You might feel tired as you are eating less than 1000kcal a day.
• If you are constipated, take a laxative like lactulose, milk of magnesia or movicol.
• If you have diarrhoea, take immodium and switch to lactofree or soya milk. If the diarrhoea continues, ring your doctor for further advice.
What is the risk of not following the diet?
Your surgery will be stopped if your liver is too large and it is not safe to continue with the surgery.
Do you have diabetes?
Please speak to your diabetes team before starting this diet. Your diabetes team will advise you on any changes to your medications for diabetes as you will only be having 120g of carbohydrate per day. If you take insulin or tablets that can cause hypos, you need to check your blood sugar levels at least 4 times per day.
Do you have kidney problems?
This diet is often not suitable if you have problems with your kidneys. Speak to your kidney doctor before starting this diet.
How long do I need to follow the diet?
You must follow the diet for two weeks before your operation.
