Diet for Gastric Sleeves
If you want to undergo gastric sleeve surgery, you must adhere to a rigorous diet that begins two weeks before the operation.
The goal of your gastric sleeve pre-op diet is to lower the size and weight of your liver in order to make the procedure simpler.
Your gastric sleeve post-op diet will aid in your recovery and help you prevent issues.
You will go from liquids, pureed, and soft meals to a final diet of nutritious protein-rich, low-calorie solid foods that you will need to follow for the rest of your life to achieve and maintain your weight reduction objectives.
Your ability to maintain a healthy diet and lifestyle will be critical to the success of your gastric sleeve operation.
Your bariatric team will educate you on your gastric sleeve diet and accompany you throughout your weight loss journey.
Pre-Gastric Sleeve Diet
If you are overweight, your liver will suffer as well. Because your liver is located directly adjacent to your stomach, having a bigger liver complicates gastric sleeve surgery and increases your chance of problems.
Your liver may rapidly diminish in size. If you adhere to a strict pre-op diet two weeks before your planned gastric sleeve surgery date, your liver will shrink, making the operation safer, faster, and simpler. This diet also prepares you for your post-op gastric sleeve diet.
A gastric sleeve pre-op diet often reduces calorie intake, decreases carbohydrate consumption, and removes sugar from the diet. You should expect to go on a clear liquid diet two days before your operation, avoiding coffee and fizzy beverages.
It is critical that you adhere to your weight loss surgeon’s two-week gastric sleeve pre-op diet. Your surgeon may also advise you to take daily bariatric multivitamins to ensure that your body receives all of the nutrition it needs.
Your body will need nutrition after your gastric sleeve surgery in order to repair your wounds and properly recover.
You will go through five eating phases: clear liquid, full liquid, pureed, soft food, and eventually a continuing protein-rich healthy diet. Each step will take around one week. You should not skip any of the stages.
Clear Liquids-Week 1
During the first week after your gastric sleeve surgery, you will continue with the clear liquid diet you began a few days before the procedure. This will allow your body to recuperate and will help you prevent post-op issues like diarrhoea, constipation, and dehydration.
You may believe that sticking to a clear liquid diet would be difficult, yet many individuals experience little or no appetite immediately after gastric sleeve surgery.
To prevent being sick, begin with sips of a clear drink. You may gradually increase the quantity of medication you take in one sitting. To prevent dehydration, make sure you drink lots of clear fluids. You should strive to consume at least 2.5 litres of water every day. Drink it when you get up in the morning and throughout the day until you go to bed.
You will be advised to take vitamin supplements in chewable or soluble form for the first two weeks after surgery. Your surgeon will provide you with further information on vitamin supplements.
Clear liquids may contain the following:
- coffee or tea that has been decaffeinated, such as herbal, fruit, or green tea.
- Broth that is clear, such as chicken, beef, or vegetable broth.
- Drinks with Marmite or Bovril
- Fruit juice, such as apple, grape, or cranberry juice, diluted.
- Squash diluted with sugar-free syrup.
- Sugar-free beverages, flavored water, and popsicles
What you should not do:
Caffeine may cause acid reflux and dehydration.
Sugary beverages may cause nausea, tiredness, diarrhea, and even vomiting. Sugar also contains a lot of empty calories.
Carbonated beverages may cause gas and bloating.
Week 2 – Finish Liquids
During the second week after your sleeve surgery, you will continue to drink lots of clear fluids while also including richer liquids high in protein in your diet. Although your hunger may grow, your digestive system is not yet prepared to handle solid foods. You should consume a wide range of nourishing drinks.
In addition to transparent liquids, full liquid options include:
Milk with a low fat content, such as semi-skimmed or skimmed, Low-calorie hot chocolate may be added to milk.

You must consume 60 grams of protein every day, so include protein in each meal. When blending your meals, consider adding milk to ensure that it is free of lumps and has a yoghurt-like texture.
You may be having a difficult time right now. Consume small servings slowly. Slowly reintroduce new meals, allowing your body time to respond to each one, so you can identify any items that are unpleasant and cause gas, stomach distress, or diarrhea.
Once you can accept pureed meals, you may choose a full A-Z vitamin and mineral supplement in tablet form to help avoid nutritional deficiencies such as iron, folate, vitamin D, and calcium.
Foods that can be pureed include:

Long-term dietary advice after gastric sleeve surgery
To accomplish and maintain your weight goals, you will need to eat a nutritious, high-protein, low-fat, calorie-controlled diet for the rest of your life.
Here are a few pointers:
Limit yourself to three modest meals every day.
Include protein in each meal and consume it first.
Introduce new meals one at a time.
As instructed by your bariatric team, take a daily vitamin and mineral supplement in tablet form. In addition, you will need vitamin B12 injections (100 mg every three months).
Consume your meal slowly and completely. The more you chew, the simpler it is to swallow and digest your meal.
Plan your meals so that you are not tempted by forbidden items.
Drink lots of water and have some on hand at all times.
If you’re hungry between meals, consider drinking something first since your body may be confusing hunger with thirst. If you’re still hungry, try a little snack like a piece of fruit or a low-fat yogurt.
Ask for half servings at restaurants; they may be cheaper, plus it may save you from overeating.
Foods to avoid include:
Foods with low nutritional value: Make wise dietary choices and avoid foods with low or no nutritional value.
- Alcohol is abundant in calories, and your absorption of alcohol will rise considerably following surgery.
- Fizzy beverages should be avoided since they promote bloating and possibly expand your tiny stomach.
- Foods high in fat might make you feel nauseated and will not help you lose weight.
- Tough meats are difficult to chew and digest.
Things to avoid include:
Eat and drink separately if possible; wait at least thirty minutes between meals. Drinking fluids with meals may result in a bloated stomach and vomiting. It may also cause your stomach to expand and “wash” your meal through too rapidly, causing you to miss early symptoms of fullness and lead to overeating.
Avoid overeating by stopping when you’re full. Overeating can cause your stomach pouch to expand and may cause you to vomit.
Avoid nibbling since it adds additional calories to your restricted diet. It also impairs your body’s capacity to burn fat since insulin levels are continually increased.
