Bariatric surgery – where you will meet a dietitian

Bariatric seminar

When you attend the seminar you will have your weight and height recorded. This will be confidential and not disclosed to anyone else attending the group.  Following a talk by one of the surgeons we will also give a presentation. This will include information on the dietary changes you will need to make before and after surgery. You will have an opportunity to ask questions.


If you decide you wish to continue on the surgery pathway you will have the opportunity to ‘opt in’ on the evening. If you require more time you will be able to ring within one month to make an appointment.


The next step

If you decide to ‘opt in’ for surgery you will attend an assessment appointment. Your medical history will be discussed with a bariatric nurse and you will see one of the dietetic team. We will talk about your weight history, your attempts at losing weight and your eating habits. Please be honest with us as this will help us decide the best treatment plan for you. It is also a chance for you to ask questions and discuss any concerns you may have.


At this point you will be given an individual weight loss target. This is an amount of weight we expect you to lose before your next appointment. You will also be encouraged to make other lifestyle changes. You will be required to complete the dietetic led Wear Living Well programme. This will help you achieve these changes. 


Before surgery

Having any weight loss surgery is not an easy option – it will not force you to follow a healthy diet. Surgery can help you lose weight but the amount you lose and how healthy you become depends on your hard work and determination.


Surgery restricts how much you can take in at a time. This helps you to limit your food intake and therefore lose weight. However, the procedures do not physically stop you from eating any foods you want to eat. You are still ultimately responsible for the food you choose to eat. You will need to use willpower to stop eating energy dense foods such as crisps, chocolate, biscuits etc. Even small amounts of these foods can slow down your weight loss.


It is quite common to eat to provide comfort or to help cope with stressful or distressing situations. Realistically we cannot change the fact that you are likely to experience stressful or difficult things at some point in your life. It is very important to find alternative ways of coping with these. If this is an ongoing problem you may be asked to see our clinical psychologist.


If you continue comfort eating, you may find you don’t lose the amount of weight you want even following surgery. Food can no longer be your way of coping if you wish to lose weight and it is important to be aware that you will need to make many adjustments.


We recommend that people start making changes to their diet and behaviour before surgery because surgery alone will not change your eating habits

You need to gradually prepare yourself for the changes ahead. Use the time before surgery wisely as you will cope better afterwards.


Preparing for surgery

When you are placed on the waiting list you will then receive a copy of the pre op diet information sheet.

Bariatrics Pre Op Diets (May 2015)

This is a diet that must be followed for 10 days prior to surgery ONLY. The purpose of the diet is to reduce the size of your liver and make the operation safer.  It must not be used at any other time. There are 3 options:-

Option 1 – Menu one food choices and menu ideas
Unless you are diabetic this is the diet you are encouraged to follow.

Diet One – food choices and menu ideas

Option 2 – Menu two food choices and menu ideas

This is suitable for diabetics on insulin.

Diet Three – food choices and menu ideas

You must keep to one diet and not combine or change options. This diet must only be used for the 10 days prior to surgery. It is not a diet to lose weight and must not be used at any other time.



During your stay in hospital you will be visited by a dietitan. We will go through the post surgery dietary advice in detail and answer any questions you may have.  Written information will be given.  You will need to follow a pureed diet for 4 weeks after this surgery.  This is important to aid the healing process.

Vitamins after your surgery

You will need to take vitamin/ mineral supplements for the rest of your life. This is a multi vitamin and mineral following a gastric sleeve or gastric band.

Following a gastric bypass you will need a multivitamin, calcium/vitamin D, and iron daily. You will also need to have a vitamin B12 injection every 3 months.


Medications after a gastric bypass 

Following your surgery you will have regular blood tests and be advised on any changes you need to make to your ongoing vitamin supplements.  Please see attached booklet.
