  • Last Updated: 2 January 2023


The aim of this dietary advice is to help you re-introduce food following Laparoscopic Nissen’s Fundoplication.

As a result of your surgery, the top of your stomach is wrapped very tightly so the opening into your stomach has become very narrow. It is therefore important to follow this dietary advice to prevent a blockage, discomfort and vomiting.

Your stomach may have reduced in size slightly; therefore you may feel full easily.  We recommend you eat ‘little and often’.

If you have a milk intolerance, cow’s milk protein allergy or are vegan then you may wish to speak to a Dietitian for more tailored advice.

Main Aim of Diet

  • Week 1 Thin Pureed diet
  • Week 2 Thick Pureed diet
  • Week 3 Minced & Mashed diet
  • Week 4 Gradually introduce more textures

General Information

  • You may lose weight
  • It is important to have regular nutritious drinks to maintain your nutrition
  • Eat high calorie, high protein, little and often, aiming for 6-8 small meals/snacks daily
  • Avoid fizzy drinks for 8 weeks
  • Ensure you are sitting upright during meals and for 30 minutes after

High Energy or Protein Drinks

If you are struggling to eat, a drink can be taken between meals if necessary. The following options will count towards your fluid intake and will increase your energy and protein intake.


  • Complan or Build Up – both the sweet and savoury flavours can be made with cold or hot water but using cold or hot milk will give a creamier texture and extra calories
  • Milkshakes or yoghurt shakes, for example: supermarket own brands, Frijj, Yop, Kefir
  • Add milkshake flavouring and skimmed milk powder to ordinary milk to make enriched milk

You may be recommended to take nutritional supplement drinks to help increase your calorie and protein intake.


  • You may feel full quickly therefore take small bites, chew foods well and sip fluids slowly
  • Avoid fizzy drinks for at least 8 weeks
  • Ensure you are sitting upright during meals and for 30 minutes after
  • Fortify food where able by adding additional cream/cheese/butter/milk

If you are struggling with your intake your GP or practice nurse can refer you to your local community dietitians.

General Advice and Consent

Most of your questions should have been answered by this leaflet, but remember that this is only a starting point for discussion with the healthcare team.

Consent to treatment

Before any doctor, nurse or therapist examines or treats you, they must seek your consent or permission. In order to make a decision, you need to have information from health professionals about the treatment or investigation which is being offered to you. You should always ask them more questions if you do not understand or if you want more information.

The information you receive should be about your condition, the alternatives available to you, and whether it carries risks as well as the benefits. What is important is that your consent is genuine or valid. That means:

  • you must be able to give your consent
  • you must be given enough information to enable you to make a decision
  • you must be acting under your own free will and not under the strong influence of another person

As part of your care, information about you will be shared between members of a healthcare team, some of whom you may not meet. Your information may also be used to help train staff, to check the quality of our care, to manage and plan the health service, and to help with research. Wherever possible we use anonymous data.

We may pass on relevant information to other health organisations that provide you with care. All information is treated as strictly confidential and is not given to anyone who does not need it. If you have any concerns please ask your doctor, or the person caring for you.

Under the General Data Protection Regulation and the Data Protection Act 2018 we are responsible for maintaining the confidentiality of any information we hold about you. For further information visit the following page: Confidential Information about You.

If you or your carer needs information about your health and wellbeing and about your care and treatment in a different format, such as large print, braille or audio, due to disability, impairment or sensory loss, please advise a member of staff and this can be arranged.
