Gastric Sleeve Regrets

Gastric sleeve surgery, also known as sleeve gastrectomy, can be a promising solution for individuals looking to lose weight and lead a healthier life. However, like any surgical procedure, it comes with its own set of challenges and potential unexpected side effects.


In this blog post, we will compile common regrets and complaints from those who have undergone gastric sleeve surgery. These real-life experiences can serve as a crucial guide for anyone considering the procedure.

We will delve into the most frequently reported issues post-surgery in detail. Understanding what to expect before and after the surgery can help you make informed and healthy decisions. Keep reading to learn about the potential challenges you may face during this process.


After Gastric Sleeve Surgery Loss of Taste Enjoyment

After gastric sleeve surgery, some patients experience a decreased sense of taste or a general disinterest in food. This can lead to significantly less enjoyment from meals. This regret is commonly observed, particularly among individuals who had a strong attachment to food before the surgery.


Changes in taste perception and the diminished pleasure from eating are part of the psychological and physical adjustment process following surgery. If this issue persists long-term, it can negatively impact mental health and increase the risk of weight regain. Old habits, such as food addiction, may resurface, leading to stomach stretching and weight gain.

To manage this situation, it is crucial to work with a trained dietitian, psychologist, or doctor who can help you repair your relationship with food and regain control. Experts can assist you in developing healthy eating habits and coping with food addiction.


Scientific Insight: Research indicates that 20-30% of patients report changes in taste perception after gastric sleeve surgery. This issue is typically more pronounced in the first six months post-surgery and tends to diminish over time.

After Gastric Sleeve Surgery Diet - Difficulty Adapting to Slow Eating Habits

After gastric sleeve surgery, eating quickly can become a significant problem. Developing the habit of slow eating before the surgery can make the adjustment period smoother. Eating too quickly can cause your small stomach to become overly full, leading to discomfort and pain.


To prevent food from getting stuck in the small stomach, you should eat slowly and chew your food thoroughly. Ensure that each bite is the consistency of mashed potatoes before swallowing. Take small bites and continue eating slowly. Each meal should involve consuming about 2 tablespoons of food over 10-15 minutes. These mindful eating practices make meal times more manageable and help you enjoy your food.

To better manage this situation, it is advisable to work with a trained dietitian, psychologist, or doctor who can help you develop mindful eating habits and break the cycle of overeating. Experts can guide you on how to eat slowly and adopt healthy eating practices.


Scientific Insight: Studies have shown that slow eating habits increase the feeling of fullness and aid in weight control. About 60% of patients who eat quickly post-surgery experience stomach discomfort and food impaction issues.

Loose Skin After Weight Loss

Rapid weight loss is a common outcome after gastric sleeve surgery and often results in excess skin. Depending on the amount of weight lost, your age, and skin elasticity, you may find yourself dealing with loose skin in various areas of your body. With the rise in obesity and subsequent weight loss surgeries, more individuals are facing this issue.

Loose Skin After Weight Loss

Body contouring surgery, a cosmetic procedure performed after bariatric surgery, aims to remove the excess skin caused by significant weight loss. This procedure can target areas like the neck, arms, shoulders, chest, abdomen, back, groin, and legs. It can enhance your self-confidence, improve comfort, make clothing fit better, and facilitate easier exercise.


One of the most common concerns after weight loss surgery is the loose, sagging skin that remains, particularly around the abdomen, upper arms, and thighs. Fortunately, there are various surgical and non-surgical skin tightening procedures available. When faced with this issue, consulting with a specialist can help you find the right solution.


Scientific Insight: Research indicates that 70-80% of patients experience excess skin problems after bariatric surgery. Skin removal surgeries have been shown to improve quality of life and self-confidence in 90% of these patients.

Body Dysmorphia and Mental Preparedness After Weight Loss

After gastric sleeve surgery, many individuals experience physical weight loss, but adjusting to their new body image can take time for their brains to adapt. Body dysmorphia is a mental health issue characterized by obsessively focusing on perceived flaws in one's body, and it can affect many obese patients post-surgery.


If you had known how mentally and emotionally challenging this situation could be, perhaps you would have reconsidered gastric sleeve surgery. Overcoming body dysmorphia takes time and numerous adjustments. During the first year post-surgery, you may still see your old body in the mirror, leading to stress, feelings of failure, and disappointment. However, as you notice progress, you'll begin to feel more confident and satisfied. The support of your family and friends will be crucial during this process.


Gastric sleeve surgery is a serious and life-changing experience that can be challenging. The best support system often begins with your family and close friends and is reinforced with the support of a registered dietitian, therapist, and doctor. Experts can help you maintain your mental and emotional health post-surgery.


Scientific Insight: Research indicates that 30-50% of patients who undergo bariatric surgery experience body dysmorphia during the post-operative period. Additionally, 25% of these patients develop serious long-term mental health issues. Therefore, receiving psychological support both before and after surgery is crucial for successfully managing the process.

Hair Loss After Bariatric Surgery

Rapid weight loss following gastric sleeve surgery can bring about a common side effect: hair loss. This usually begins around 3 to 6 months post-surgery and can last up to 12 months.

Hair Loss After Bariatric Surgery

Consuming less food and decreased nutrient absorption due to the surgery lead to rapid hormonal changes in your body, increasing stress and causing hair loss. While hair loss is temporary and your hair will eventually grow back, this process can be quite distressing.

Don't worry; your hair will naturally regrow thicker and stronger. If your hair was thin before the surgery, the loss may be more noticeable, but you can minimize this issue with proper

nutrition and care.


Quick Tips to Minimize Hair Loss:

Protein Intake: Consume at least 60 grams of protein daily.

Vitamin Supplements: Regularly take recommended bariatric vitamin supplements.

Biotin and Zinc: Add biotin and zinc to your supplement regimen.

Use Special Shampoos: Use effective shampoos against hair loss, such as Nioxin.

Consumption of Seafood: Add seafood rich in omega-3 fatty acids to your diet.


These steps can help you control hair loss and support healthy hair growth. Many individuals experiencing hair loss after gastric sleeve surgery have observed their hair returning stronger and healthier with proper nutrition and care.


Scientific Insight: Research shows that 30-40% of patients experience hair loss after gastric sleeve surgery. Adequate protein and vitamin intake play a significant role in reducing hair loss and improving hair health. The use of supplements like biotin and zinc during this process can reduce hair loss by up to 50%.

Altered Relationship with Food After Obesity Surgery

Being unprepared for how profoundly your relationship with food will change after gastric sleeve surgery ranks 5th on our list of regrets. Before the surgery, eating was not only about sustenance but also about socializing, self-reward, and an emotional outlet.


However, post-surgery, the shift to eating as a necessity can be surprising and challenging for many patients.

Altered Relationship with Food After Obesity Surgery

Now, eating may feel like a chore rather than a pleasure. Many patients express not enjoying eating and doing it out of necessity. This significant emotional shift requires a significant adjustment period post-surgery. Eating is no longer a source of pleasure but rather a task to fulfill your body's needs.


A patient's experience might be: "I'm definitely not regretting the surgery. I just wish I had been more prepared for the significant emotional change I would have to deal with regarding food." Such experiences underscore the importance of understanding how deeply your relationship with food will change.


To avoid developing eating disorders, it's essential to stay in touch with your body and emotions. Working with a registered dietitian, therapist, or doctor during this process can help you maintain your emotional and physical health.


Scientific Insight: According to research, 50-60% of patients report significant changes in their relationship with food post gastric sleeve surgery, finding it emotionally challenging. Getting psychological support post-surgery reduces the risk of developing eating disorders in 40% of patients. Hence, seeking expert support to manage your relationship with food healthily is crucial.

Choosing Gastric Sleeve Surgery Over Gastric Bypass

Gastric sleeve surgery may not yield perfect results for everyone. The reality is that some patients who opt for this surgery may experience regret for not choosing gastric bypass surgery instead. There are two main reasons for this regret:


Gastric Bypass

Acid Reflux and GERD: 

Patients with acid reflux or gastroesophageal reflux disease (GERD) before surgery are typically advised to opt for gastric bypass surgery instead of gastric sleeve. The restriction in the stomach post gastric sleeve surgery can worsen acid reflux and GERD. Gastric bypass surgery often manages these reflux issues better.

Inadequate Weight Loss: 

Some patients feel they haven't lost as much weight as they expected after gastric sleeve surgery. This may lead to a feeling that they should have opted for gastric bypass surgery, which is believed to provide more significant weight loss.


However, gastric sleeve surgery has many advantages. It is less invasive than Roux-en-Y gastric bypass and does not alter the direction of the intestines. Additionally, if you don't achieve the desired results, gastric sleeve surgery can be easily revised.

Over time, the weight loss achieved with gastric sleeve surgery may be comparable to that with gastric bypass surgery. Therefore, gastric sleeve surgery is considered an effective option with a high chance of success.


Scientific Insight: Studies show that 20-30% of patients experience worsening symptoms of acid reflux or GERD after gastric sleeve surgery. Gastric bypass surgery may be more effective in improving these symptoms. Furthermore, it's noted that there is a 5-10% difference in weight loss between gastric sleeve surgery and gastric bypass surgery in the long term, with both surgeries having similar success rates.

Unrealistic Expectations After Gastric Sleeve Surgery

Many individuals undergoing obesity surgery believe that miraculously all their weight problems will be solved after the surgery, and they will never have to struggle with weight again. However, this expectation is incorrect.

After gastric sleeve surgery, adhering to post-operative diet, nutrition plans, and regular exercise is necessary to achieve permanent weight loss and a healthy lifestyle.


The surgery is just a beginning, and a disciplined approach is essential for the success of your weight loss journey. After surgery, incorporating healthy eating habits and regular physical activity into your life is crucial. During this process, doctors, nutritionists, and support groups will guide you to help maintain your motivation.

Remember, this life transformation can be challenging, but like all challenges in life, overcoming them will bring you more satisfaction and confidence. Knowing that you are not alone in your journey will give you strength and motivation.


Scientific Insight: Research shows that 80% of patients who undergo gastric sleeve surgery lose a significant amount of weight within the first year post-surgery. However, to sustain this success, 60% of patients must adhere strictly to diet and exercise plans for the first five years post-surgery. Patients who participate in support groups have been observed to achieve more successful long-term weight loss results.

Post-Surgery Workload and Challenges

Gastric sleeve surgery isn't just a journey during the operation; it requires significant effort even after the procedure. If you're not ready to make permanent changes, this life-altering experience won't yield the expected results. Those who think surgery offers an easy way out are mistaken; this is entirely untrue.

Gastric sleeve surgery can lead to losing 100 kilograms or more, bringing about a significant transformation in your life. However, you must remain committed to a strict diet and exercise regimen post-surgery. This process won't be easy, but the results will be highly rewarding when you put in the effort.



Post-surgery challenges manifest not only physically but also psychologically and socially. For instance, people may inquire about how little you eat when you dine out. This involves challenges such as meal preparation, pre-planning your meals, and avoiding tempting foods at every turn. It requires constant attention and discipline.


Scientific Insight: In the first year after gastric sleeve surgery, 70-80% of patients achieve their desired weight loss. However, maintaining this success requires strict adherence to diet and exercise plans. Research shows that patients who adhere to diet and exercise plans in the first five years post-surgery maintain 60% of their weight loss.

During the post-surgery period, regular doctor check-ups, consultations with dietitians, and participation in support groups enhance your success rate and guide you through this challenging process. Feeling prepared and disciplined is critical for long-term success.



Not Having Surgery Sooner

One of the most common regrets among those who undergo weight loss surgery is, "Why didn't I do this sooner?" When health improves significantly and all health indicators are in excellent condition, this thought often lingers. "I no longer have diabetes, I no longer suffer from sleep apnea... Everything became so much easier..."


Making the decision to undergo surgery requires courage. People often spend a long time contemplating this choice without telling anyone because they don't want to hear discouraging comments. However, once the decision is made, the process usually progresses much more smoothly than anticipated. Even the diet, despite the initial challenges of caffeine and sugar withdrawal, leads to the body feeling better almost immediately.



As seen in this person's story, the journey of weight loss and adopting lifestyle changes post-surgery can be incredibly rewarding. Losing 50% of their original body weight, amounting to 171 pounds in 14 months, is a remarkable achievement. Engaging in daily exercise, running distances, and lifting weights has significantly enhanced this person's quality of life.

In conclusion, being ready to take a major step like weight loss surgery is the most crucial factor in ensuring the process is successful. When you are prepared, this transformation in your life awaits you.



Success after weight loss surgery depends on the patient's preparation before the surgery and the lifestyle changes they adopt afterward. Research shows that postoperative weight loss is linked to how well patients adhere to their diet and exercise plans. For long-term success, it is essential for patients to maintain these lifestyle changes post-surgery.
