What is the best Pre and Post Post Gastric Sleeve Surgery Diet

Pre and Post Post Gastric Sleeve Surgery Diet and Nutrition: How Will Bariatric Procedures Affect Your Diet?

It is increasingly harder these days to lose weight AND keep any lost kilos from coming back to haunt us with meal times all over the place, readily available junk food and super busy lifestyles, that is why your Gastric Sleeve Surgery Diet is so important.

Many of us do not even realise that we are putting on weight until quite late into the ‘gaining cycle.’ When nothing fits anymore, panic can set in.  Then thought then of reducing excess weight starts to go through our minds. What can be done at this very important stage of the start of your weight loss journey?


The issue of obesity in today’s society?

Our busy lives, laden with sugary drinks and fast-food availability – along with “bulk buy” or super-size food purchases – there is now a national epidemic of obesity. Unfortunately, it’s not as easy to lose weight as it is to gain it, and our current lifestyles are definitely not helping.

Once we are at an unhealthy Body Mass Index (BMI), we also find that our joints don’t allow our bodies to safely exercise without pain or risk of injury to our overall health including joints and ligaments.


When Surgical Intervention becomes the only option when people cannot lose enough weight

Some people can struggle daily to lose weight after becoming grossly overweight or overweight to the point of being obese (which means having a BMI of over 29.9 or 30).  Despite exercising and healthy eating – no amount of dieting seems to move the excess weight. Reasons for this are often multi-faceted, including metabolic and hormonal changes, issues with the thyroid gland or even brain chemistry that fails to trigger a feeling of ‘fullness’ after eating.


Genetics, brain chemistry and lifestyle choices are all often intertwined in the development of obesity.

Obese people are likely at the point that their stomach has the capacity to consume far more calories than they should and could ever hope to burn off – no matter how much they persist with regular exercise.

Living with obesity is very dangerous to health and longevity of life. We also recognise that crash diets have adverse impacts on our health. Extreme diets can be very taxing on the organs and other body systems and functions. Extreme diet regimes are  unlikely to help keep the weight off over time; in fact, diets often lead to further weight gain once you go back to normal.


Weight, Waistline & BMI factor into Obesity and associated Health Problems

Where your weight, your waistline and your BMI are at dangerously high levels, your GP or Specialist may recommend weight loss surgery options such as a Gastric Sleeve, Gastric Band Surgery, Gastric Bypass or Lap Band surgery procedures.


What exactly is Gastric Sleeve Surgery?

  • Gastric sleeve surgery involves reducing the size of the stomach, which helps patients lose weight by limiting how much food they can comfortably or safely consume without feeling uncomfortable.
  • Once the size of the stomach is reduced, a person’s appetite is also reduced and they feel hungry less often.
  • A smaller stomach size gives the sensation of being fuller, faster, which also helps to decrease food intake and excessive calorie consumption.

Gastric Sleeve Surgery is gaining more popularity as it has a much shorter procedure time than Gastric Bypass or Lap Band Surgery and is effective at helping people lose weight to overcome obesity.

Unlike the lap band, no adjustments are needed with a Gastric Sleeve Procedure. It appears that surgical patients are able to lose more weight with a Gastric Sleeve compared to a Lap Band procedure or a Gastric Bypass.


Gastric Sleeve Diet and your Liver health BEFORE your surgery  

If you choose to have Gastric Sleeve surgery, your Specialist Bariatric Surgeon or Obesity Surgery Specialist has specific pre-surgery and post-op diet details that are beneficial to follow.

  • They will advise you of any potential complications and surgical risks of gastric surgery to overcome obesity and help you lose weight.
  • Several weeks prior to your surgery (at least 4 weeks before your surgery), you’ll likely be advised to undertake a special diet to help reduce the size of your liver.
  • This is due to an enlarged or ‘fatty’ liver impacting on your Surgeon’s access during your Bariatric operation.
  • A fatty liver also increases the risk of having serious complications from gastric surgery. Therefore, diligence is imperative when following your pre-op nutrition instructions and the prescribed liver-reducing diet click here for an example.

Changing your diet BEFORE your Gastric Sleeve Surgery not only helps to leave you healthier, it also helps you prepare for an altered diet that will need to be continued AFTER your gastric bypass surgery.

  • With your pre-surgery eating plan, you’ll likely be told to consume more protein and less carbohydrates than your normal eating regime.
  • Eliminate added sugars and avoid soft drinks (this will help to reduce your weight as these sugary drinks are a contributing factor in higher obesity rates).
  • Drink lots of fluids and clean liquids to stay well hydrated (water is best).
  • Your Gastric Sleeve Surgeon may advise you to undergo a strict liquid diettwo days out from your surgical date.
  • Your Bariatric Surgeon will likely give you specific instructions for the time (months, weeks and days) before your surgery.
  • Preparation and planning is very important for bariatric surgery patients and can take more time than most realise.
  • If you are considering Gastric Sleeve, Gastric Band Surgery, Gastric Bypass or Lap Band surgery procedures, be sure to book a consultation with your chosen Bariatric Surgeon as soon as you know you’re wanting the surgery to best prepare yourself for the procedure.

Nutritional Changes AFTER Gastric Sleeve Surgery

In the days, months and years following your gastric sleeve surgery, you’ll need to take the utmost care with your nutritional intake and eating routines. (ASK your Surgeon as this will differ between patients).

In general, here is the general eating advice given to patients who are about to have Gastric Sleeve operations – but YOUR instructions could vary so ask your Doctor or Surgeon for specific post-op care to suit your particular health needs.




Week One after Gastric Sleeve Surgery Diet – What Might Be Typical

*The information below is of a general nature and is not intended as advice.  It is NOT a substitute for the medical information or pre and post-op recommendations given to you by your GP and Gastric Surgeon or any other health professionals assisting you with your medical care. It is intended only as an information starting point for discussions with your specialist about how you’ll need to adapt your eating style after Surgery. Every patient, every procedure and every Bariatric Surgeon and Nutritional Team has a unique approach – so please, follow your Specialist’s instructions.


Week One After Gastric SleeveSurgery Diet: Consumption of Clear Liquids

  • First week after your gastric sleeve surgery, you may be allowed ONLY to take in clear liquids such as water, fresh juices, soups and or broths.
  • You’ll typically be told to take small sips of these liquids to ingest very slowly.
  • Decaffeinated tea and coffee are usually okay a few days after your Surgery (check this with your Surgeon, as this may not be permitted for you in relation to your health or specific procedure.
  • You should, avoid ALL carbonated beverages and drinks with added sugars.
  • If you’re readily able to tolerate liquids, then your Surgeon will advise you when you can advance to the next stage of your eating plan.


Week Two After Gastric Sleeve Surgery Diet: Pureed Foods

  • You may now typically take in foods in a pureed form
  • Things like, mashed potatoes, low-fat cottage cheese, sugar-free yogurt, soup with blended vegetables and hot watery oatmeal.
  • Don’t be tempted to overdo it. It’s not worth the risk and may cause discomfort very quickly if the wrong foods are consumed (or too much of the right ones) after surgery.


Week Three After Gastric Sleeve Surgery Diet: Protein Shakes and Soft Foods

  • Week three, you might be able take protein shakes around once a day.
  • Possible approval to eat hummus, steamed or boiled vegetables, soft cereals, scrambled eggs, mashed fruits, steamed fish, ground chicken with stock and soups.
  • Avoid Starchy foods like rice, pasta and bread.
  • Also avoid fibrous vegetables like broccoli, celery and asparagus as they are difficult to digest.




Week Four After Gastric Sleeve Surgery Diet: Some Solid Meals

  • Week four, your eating regime may now include some ‘solid’ meals.
  • You may start eating some fruits, sweet potatoes, baked potatoes, cereals, fish and chicken.
  • Avoid eating fried foods, desserts, lollies, whole milk and nuts as these are very difficult to digest.
  • Hard-boiled eggs, bananas or hummus with soft rice crackers are good options, but be sure to check with your Surgeon and or Nutritionist/Dietitian.
  • It’s important to keep in mind that your meals should have a high nutritional value (or be nutrient-dense) as well as remain sparse in calories.
  • During the following week, you can typically have one or two healthy snacks in-between meals.

During the months AFTER your surgery, you’ll have been given specific eating recommendations from your Surgeon, so monitoring your eating regime and portion control is a good idea.

How Long Before I see Weight Reduction after Gastric Sleeve Surgery?

Patients have been known to start seeing weight change results just weeks after their gastric surgery procedures. On average, with Gastric Surgery, you can anticipate losing around 60% of your pre-surgery weight. (Everyone is different, and It is important to follow your Surgeons advice to achieve the best results.)


What about my skin after Gastric Band or Gastric Sleeve procedures?

Gastric sleeve surgery and other weight loss procedures can leave you with extra ‘sagging’ baggy skin. Redundant Skin is the medical term used for the post-weight loss skin (rolls or sagging skin) and it typically needs to be surgically reduced (excised), usually along with liposuction.

Sadly, you can’t exercise skin off. Excess skin, along with stubborn fat stores, even after significant weight loss, means you’ll probably require more surgery. This is so you can achieve the body contours you are wanting after working so hard to get a healthier, more natural body shape after a massive weight loss.

If you need your redundant skin reduced to achieve smoother body contours, our leading Plastic Surgeons Directory offer many various Body Contouring procedures. The most common cosmetic surgeries or plastic surgeries after significant weight loss occurs include:
