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.
Following surgery,
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:
·
Water
·
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.

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.

your meals, consider adding milk to ensure that it is free of lumps and has a
yoghurt-like texture.

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.

deficiencies such as iron, folate, vitamin D, and calcium.

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.
