Bariatric surgery is a well-researched and effective long-term weight-loss solution, but misinformation and outdated opinions often discourage people from exploring it. Understanding the facts is essential for anyone considering weight-loss surgery.
In this blog, Dr. Niruben Rajasagaram clears up many of the misperceptions people may have about intrusive surgical weight loss and gives the patients accurate, fact-based data to be able to make a better-informed decision about their options. Whether you are looking to have bariatric surgery in Melbourne or want to have a better understanding of the various options available for you to consider, separating the myths from the facts is the first step.
Understanding Bariatric Surgery
Bariatric surgical procedures are performed in many different ways to assist obese individuals in controlling their weight by modifying the body's mechanism for digesting food. These surgeries are not cosmetic, but rather surgical medical treatment to improve an individual's health, reduce obesity-related issues and promote an individual’s success in maintaining their weight in the long term. Bariatric surgical procedures include sleeve gastrectomy (referred to as vertical sleeve gastrectomy or gastric sleeve), gastric bypass and revisional (or second assistance) bariatric surgery.
All patients will go through a complete evaluation by a qualified bariatric specialist to ascertain their best option for a bariatric surgical procedure based on the individual’s medical history, body mass index (BMI) and current medical necessity of surgery.

Common Myths About Bariatric Surgery
Below are some of the most common myths surrounding bariatric surgery, clearly explained and addressed by Dr. Niruben Rajasagaram to help patients understand the facts.
Myth 1: Bariatric Surgery Is the “Easy Way Out”
Fact: Bariatric surgery is not a shortcut, it is a medical procedure.
Surgery by itself cannot cause sustainable long term weight loss. To have long-term successful weight loss surgery requires lifestyle changes in addition to surgery, such as nutrition, exercise, and medical follow-up. After surgery, patients must commit to making changes in their eating habits, how much they eat, and monitoring their progress regularly (at least once/month).
While bariatric surgery will help with reducing hunger, improving metabolism, and restricting food intake, patients need to have the desire and determination to make these lifestyle changes to achieve successful long-term results.
Myth 2: Only Extremely Obese People Qualify for Bariatric Surgery
Fact: Eligibility is based on health, not just weight.
Bodyweight is an important part of whether you qualify or not for bariatric surgery, but there are also clinical reasons (obesity-related health problems) for someone to have surgery. Many patients who will not be recognised as “extremely obese” may still qualify for bariatric surgery because of the associated medical risk of being overweight. A bariatric surgeon will assess a patient with acceptance of international medical criteria for eligibility.
Myth 3: Bariatric Surgery Is Unsafe
Fact: Modern bariatric surgery is highly safe when performed by experienced surgeons.
Improvements in surgical techniques, especially minimally invasive (laparoscopic) technologies, have reduced the risk of complications associated with bariatric surgery. Bariatric surgery today has safety outcomes comparable to other common surgical procedures, such as gallbladder removals.
There are risks with all types of surgery; however, by having a thorough pre-operative assessment and a structured aftercare program, the risk of developing complications can be reduced.
Myth 4: You Will Regain All the Weight After Surgery
Fact: Long-term weight loss is achievable with proper follow-up.
Weight regain can occur if lifestyle changes are not maintained, but most patients achieve sustained weight loss when they follow medical guidance. Bariatric surgery works by altering appetite hormones and digestion, making it easier to manage hunger and portion sizes. Ongoing support from healthcare professionals plays a critical role in long-term success.
Myth 5: Bariatric Surgery Means You Can Never Eat Normally Again
Fact: Eating patterns change, but food enjoyment remains.
After surgery, patients eat smaller portions and focus on nutrient-dense foods. This adjustment is necessary to support weight loss and health, but it does not mean giving up normal meals forever.
Over time, patients develop balanced eating habits that fit their lifestyle while protecting their surgical results.
Myth 6: Bariatric Surgery Is Only About Weight Loss
Fact: The primary goal is improved health.
Weight loss is important, but bariatric surgery also helps improve or resolve serious health conditions. Many patients experience better blood sugar control, reduced blood pressure, improved cholesterol levels, and relief from joint pain. For many, the greatest benefit is improved quality of life and increased mobility rather than the number on the scale.
Myth 7: Gastric Sleeve Surgery Is Reversible
Fact: Sleeve gastrectomy is a permanent procedure.
Gastric sleeve surgery in Melbourne is one of the most commonly performed bariatric procedures. It involves removing a portion of the stomach to reduce its size and appetite hormone production. Unlike some other procedures, it is not reversible. This is why careful evaluation and informed decision-making are essential before proceeding.
Myth 8: Bariatric Surgery Is a One-Time Fix
Fact: It is the beginning of a long-term health journey.
Surgery is only one part of obesity treatment. Lifelong medical follow-up, nutritional monitoring, and healthy habits are necessary. Some patients may require revisional bariatric surgery due to medical reasons, anatomical changes, or evolving health needs. Regular check-ups ensure early detection of issues and ongoing success.

Frequently Asked Questions
Who is eligible to have bariatric surgery?
Your weight and body mass index (BMI) are some of the characteristics that make you eligible for surgery. Some examples of obesity-related conditions include type 2 diabetes, hypertension, and sleep apnea. A consultation with a bariatric surgeon, reviewing your overall health, previous attempts at weight loss, and your medical history will help the surgeon determine if you are an appropriate candidate for surgery.
Which types of Bariatric Surgeries are available in Melbourne?
The three most common types of bariatric surgeries offered in Melbourne are gastric sleeve surgery, gastric bypass surgery, and to a lesser extent adjustable gastric band surgery. The final decision as to what type of surgery is the most appropriate for you will be based on your overall health, your goals for weight loss, and how you will choose to live your life after surgery.
How safe is Bariatric Surgery?
Bariatric Surgery is typically very safe if performed by a qualified surgeon. Minimally invasive bariatric procedures will also help reduce complications, speed up recovery, and lead to better long-term results.
Will I regain weight after having surgery?
It is normal for most patients to regain some weight after surgery; however, if a patient follows all of the necessary dietary recommendations, participates in post-operative appointments, and changes their lifestyle habits to maintain a healthy weight, they will usually be able to maintain substantial weight loss permanently. The procedure will serve as a foundation for long-term success, but the individual will be responsible for their own success.
How long is the recovery period after bariatric surgery?
Recovery varies by procedure but generally involves a hospital stay of 1–3 days for minimally invasive surgery. Most patients gradually return to normal activities within 2–4 weeks, with ongoing dietary and lifestyle support.
