Can You Drink Milkshake After Gastric Sleeve Surgery? Explained.

Drinking milkshakes after gastric sleeve surgery is not recommended due to their high sugar and fat content. Opt for healthier alternatives instead.

Gastric sleeve surgery, also known as sleeve gastrectomy, is a weight-loss procedure that involves removing a large portion of the stomach, leaving behind a small sleeve-shaped stomach pouch. While this surgery can be life-changing for individuals struggling with obesity, it also requires significant lifestyle changes to maintain the weight loss.

One of the key factors in successful weight loss after gastric sleeve surgery is a healthy diet. Drinking milkshakes, which are often high in sugar and fat, can potentially hinder weight loss progress and cause discomfort post-surgery. Therefore, it is advisable to choose healthier alternatives such as protein shakes, smoothies, or low-fat milk instead of milkshakes to ensure a long-term success.

Understanding The Impact Of Gastric Sleeve Surgery On Digestion

If you’re planning on undergoing gastric sleeve surgery or have already been through the process, you may be wondering about the impact of the procedure on your digestive system. Here’s what you should know:

  • During the procedure, 75-80% of your stomach is removed, leaving behind a sleeve-shaped tube that can hold less food. This means you’ll feel fuller much quicker than before, encouraging you to eat smaller portions.
  • After gastric sleeve surgery, food passes through your digestive system differently. It goes directly from your small stomach pouch to your small intestine, bypassing much of your stomach. This can speed up digestion but affects the absorption process, leading to changes in nutrient availability.
  • The surgery can also affect your hunger hormones, particularly ghrelin, which is known to regulate food intake. Ghrelin is produced mostly in the part of the stomach that gets removed during the procedure, significantly reducing its levels.

Understanding The First Few Weeks Of Post-Surgery Recovery

Recovering from gastric sleeve surgery is a gradual process. Here’s what to expect in the first few weeks after your procedure:

  • You’ll likely spend an average of three days in the hospital to ensure you’re recovering well.
  • After returning home, you’ll need to give yourself time to rest, with most patients only able to manage short walks around the house.
  • You’ll be on a liquid diet for the first few days, gradually advancing to pureed and soft foods over a few weeks. Your surgeon can provide a customized plan for you to follow.
  • During this time, it’s essential to abstain from strenuous activities, lifting heavy objects, and drinking through a straw. Ensure you follow your surgeon’s post-operative instructions to avoid any complications.

Overview Of The Four-Phase Post-Surgery Diet

Following the post-surgery diet plan is imperative in ensuring optimal healing and successful weight loss. Here’s a brief overview of the four-phase diet:

  • Phase 1: Liquids only, including clear broth, sugar-free beverages, and protein shakes.
  • Phase 2: Pureed foods like cottage cheese, pureed scrambled eggs and baby food.
  • Phase 3: Soft foods like chicken and fish.
  • Phase 4: Regular foods but in smaller amounts and focusing on high-protein, nutrient-dense foods.

Remember, the importance of following the post-surgery diet can’t be overstated. Your body needs time to heal, and deviating from the prescribed meal plan can lead to complications. Ensure you work closely with your medical team to ensure a successful post-surgery recovery.

Explanation Of The Role Of Liquids In The Post-Surgery Diet

After gastric sleeve surgery, patients will need to follow a strict liquid diet to promote proper healing and recovery. Liquids are crucial because they help the body stay hydrated, prevent dehydration, and provide necessary nutrients. Drinking the recommended daily amount of liquids post-surgery can aid in maintaining weight loss, preventing complications, and promoting overall health.

Overview Of The Recommended Liquid Diet Options

Post-surgery, patients will need to consume a primarily liquid diet for several weeks. Here is an overview of recommended liquid diet options after gastric sleeve surgery:

  • Clear liquids such as water, broth, and sugar-free gelatin are initially recommended.
  • Full liquids such as soups, protein shakes, and pureed foods, are then introduced in small amounts.
  • Soft foods such as eggs, cooked vegetables, and canned fruits with no added sugar are recommended after a few weeks.

Understanding The Nutritional Content Of Milkshakes

Milkshakes are a tasty treat that many people love, especially during the hot summer months. However, after gastric sleeve surgery, it’s essential to understand the nutritional content of milkshakes. Here are some points to keep in mind:

  • Milkshakes can be high in calories, sugar, and fat.
  • Some milkshakes may contain more calories than an entire meal.
  • The nutritional value of milkshakes varies depending on the ingredients.

Pros And Cons Of Drinking Milkshakes After Gastric Sleeve Surgery

It’s natural to crave a milkshake after gastric sleeve surgery, but there are both pros and cons to drinking milkshakes post-surgery.


  • Milkshakes can help meet daily protein requirements.
  • They are easy to prepare and can be a quick meal replacement.
  • Milkshakes can help patients feel satisfied and prevent hunger.


  • Milkshakes can cause weight gain if consumed in excess.
  • The high sugar content can lead to dumping syndrome.
  • Some protein shakes can contain unhealthy additives.

Ultimately, it’s best to consume milkshakes in moderation and choose healthier options with fewer calories and sugar. It’s essential to prioritize nutrient-dense, low-calorie options to promote healthy weight loss and overall health after gastric sleeve surgery.

Alternatives To Milkshakes If Drinking Not Recommended

  • Protein shakes – they contain a high amount of protein essential for the recovery process.
  • Bone broth – it is considered a superfood as it helps in healing and is also very nutritious.
  • Vegetable puree – a puree made from vegetables like carrots, spinach, and peas can be very nutritious and easy to digest.
  • Fruit smoothies – a smoothie made from fruits like bananas, strawberries, or blueberries can provide you with similar nutritional content as a milkshake.

Explanation Of The Texture Of Food During The Post-Surgery Liquid Stage

During the post-surgery liquid stage, you will be consuming only liquids. This is because the stomach needs time to heal, and solid food can cause discomfort and interfere with the recovery process. The texture of the food during this stage will be thin and watery and will be easy to digest.

Tips And Tricks For Consuming Other Forms Of Liquid Nutrition

Consuming liquid nutrition after gastric sleeve surgery can be challenging. Here are some tips to make it easier:

  • Start slow – start by sipping small amounts of the liquid slowly. If it feels uncomfortable, take a break for a while.
  • Use a straw – using a straw can make it easier to swallow the liquid without discomfort.
  • Chew slowly – even though you’re drinking liquids, it’s important to chew slowly and thoroughly.
  • Avoid carbonated drinks – carbonated drinks can cause discomfort and are not recommended during the recovery process.

Remember to consult your doctor or nutritionist before changing your diet after surgery. Listen to your body and slowly introduce new foods to avoid any discomfort.


After undergoing gastric sleeve surgery, it is essential to follow a strict diet plan to promote a successful post-surgery recovery and long-term weight loss goals. While milkshakes may seem like a tasty treat, they can be high in calories, sugars, and fats and may not be the best choice for those with a reduced stomach size.

However, low-fat and sugar-free milkshakes can be consumed after a gastric sleeve surgery, especially during the liquid and pureed food diet phase. It’s important to work closely with a registered dietitian or a healthcare provider to determine the best and safest dietary options for your individual needs.

Remember, following a healthy and well-balanced diet plan, coupled with regular physical activity, is key to achieving and maintaining long-term weight loss goals after gastric sleeve surgery. Focus on making healthier food choices that nourish your body and support your overall health and wellness.
