Advice after your nerve block for surgery
On this page…
This information is for patients who have had an operation on the stomach or oesophagus. This includes anti-reflux or fundoplication surgery, repair of a hiatus hernia and surgery to treat achalasia (cadiomyotomy).
Why do I need to change my diet after surgery?
Surgery can cause swelling and bruising of the stomach or oesophagus. This can temporarily make swallowing difficult. This usually improves after several weeks but, in order to avoid food getting stuck in the oesophagus, we ask patients to follow a special diet after surgery.
What does this involve?
There are three stages to the post-surgery diet. These are:
- Liquid diet
- Puree diet
- Soft/fork-mashable diet
Most patients start on a liquid diet, then move on to a puree diet followed by a soft diet. Patients can then slowly return to a normal diet.
How long will I need to follow this diet?
The amount of time you spend on each stage will depend on what type of operation you have had. Your surgeon will tell you how long to be on each stage and when you can return to your normal diet.
General tips
- Eat smaller meals more frequently rather than three big meals a day (aim for 6-8 smaller meals spaced throughout day)
- Try to eat moist foods with a sauce or gravy
- Take your time with eating and drinking
- Chew your food well and carefully
- Sit upright when eating and for 30 minutes after eating
Are there any things that I should avoid completely?
Yes. Very dry foods and lumps can all get stuck in the food pipe. This can be uncomfortable and, in some cases, may need you to return to the hospital.
Foods to avoid
- Dry meat, tough meat, gristle, crackling
- Fish with bones Fish in crispy batter or breadcrumbs
- Lumps of hard cheese Food with grilled cheese toppings Dairy products containing hard pieces e.g. nuts, dried fruit
- Fried egg
- Undercooked beans or peas such as those in salads
- Soups containing large/hard lumps
- Wild rice
- Hard fibrous cereals e.g. All bran, shredded wheat, muesli
- Any type of bread or toast Dough-based foods e.g. chapatti, naan Pizza Cakes, crumpets, etc
- Green salad Raw uncooked vegetables Vegetables with tough shells e.g. peas and sweetcorn Stringy vegetables e.g. celery, green beans Gas producing vegetables e.g. cabbage, onion, Brussels sprouts
- Hard fruits Skins of fruit Dried fruit Seeds and pips
- Miscellaneous: Hard sweets, toffees, popcorn, crisps, chewing gum, biscuits, crackers
How can I prepare?
You may not feel like shopping and cooking in the first few days after surgery. It is a good idea to get some things ready before you are admitted to hospital. This includes:
- A blender or food processor
- A sieve
- Prepare some puree and soft meals in advance and store them in the freezer
- Go to the shops/ supermarket so that you have some food ready to eat for when you get home.
What do I do if my swallowing is not getting better?
If at any point you are struggling with a certain stage, please drop back to the previous stage. Try to move to the next stage again after a few days. If your swallowing fails to improve, you will need to get in contact with the hospital.
If you are unable to swallow liquids, you will need to come back into hospital.
What do I do with my medications?
This will depend on the type of operation you have had. Some people may be able to take medication as normal. Some people may need to crush their tablets or take them in liquid form. A pharmacist or your surgeon will let you know how to take any medication.
