Weight loss surgery has become more common in Australia, with more people considering procedures like the gastric sleeve and gastric bypass to manage obesity and improve long-term health. Despite its increasing popularity, many myths and misconceptions still surround bariatric surgery. These misunderstandings can create confusion or discourage people from seeking help when they need it most.
In this article, we address the most common myths about weight loss surgery, using facts and current medical guidelines. Whether you are researching options for yourself or supporting someone you care about, this guide will help separate fact from fiction.
Myth 1: Bariatric surgery is the easy way out
A common misconception is that having weight loss surgery is a shortcut or cheat. The truth is, whether you undergo a gastric sleeve or gastric bypass, the process involves lifelong lifestyle changes.
Surgery helps by reducing hunger and limiting food intake, but it does not do the work for you. You still need to make healthy choices every day, commit to regular exercise, and attend follow-up appointments. It is a powerful tool, not a quick fix.
Myth 2: You will never enjoy food again
After bariatric surgery, your relationship with food changes, but enjoyment remains. As your body heals and adapts, you can gradually return to a balanced and varied diet that includes lean proteins, vegetables, fruits, and whole grains.
Whether you have a gastric sleeve or bypass, you will learn to eat slowly, savour flavours, and stop when full. Many patients say they enjoy food more after surgery because they eat with more intention and appreciation.
Myth 3: Everyone regains the weight
While a small amount of weight regain is common a few years after surgery, most people maintain substantial weight loss over time. Studies show that procedures like the gastric bypass and gastric sleeve result in long-term success for many patients.
Support from your surgical team, dietitian, and regular check-ups help you stay on track. Regain is not inevitable and can often be prevented or managed.
Myth 4: You will become vitamin deficient or malnourished
Vitamin deficiencies are rare when you follow your post-operative plan. All bariatric procedures, especially gastric bypass, can affect absorption of nutrients, but you will be guided through a supplement routine that meets your needs.
You will also have regular blood tests to monitor your levels. With the help of your dietitian and surgical team, your nutrition can remain balanced and healthy.
Myth 5: You cannot get pregnant after weight loss surgery
Fertility actually improves after weight loss surgery. Many women who struggled to conceive due to obesity or conditions like PCOS find that ovulation returns and hormonal balance improves after losing weight.
Women of childbearing age are advised to wait at least 12 months before trying for a baby. This gives the body time to stabilise and recover, reducing the risk of complications.
Myth 6: Surgery is only for people who are morbidly obese
In Australia, bariatric surgery is offered to individuals with a BMI over 40, or over 35 if there are health problems like type 2 diabetes, sleep apnoea, or fatty liver disease.
You do not need to be at your worst to qualify. Early intervention through procedures like the gastric sleeve can prevent long-term health problems and greatly improve quality of life.
Myth 7: It is too risky
Modern bariatric surgery is safe and reliable. Procedures like the gastric sleeve and gastric bypass are performed using keyhole (laparoscopic) techniques, reducing recovery time and complications.
In Australia, bariatric surgery is performed under strict safety standards with low complication rates, especially when done by experienced surgeons. The risks of untreated obesity are often much greater than the risks of surgery.
Myth 8: You will need plastic surgery afterwards
Not everyone ends up with loose skin, and not everyone who does chooses to have it removed. Skin changes depend on many factors, including age, amount of weight lost, and genetics.
Plastic surgery after weight loss is optional and often only considered by patients for comfort or cosmetic reasons.
Myth 9: Surgery causes depression
Mental health often improves after surgery. Many patients report feeling more confident, energetic, and motivated after weight loss.
That said, emotional changes can occur, especially as food is no longer used for comfort. Good surgical programs include access to psychologists or counsellors to support your wellbeing through all stages of the journey.
Myth 10: Surgery should be the last resort
Bariatric surgery is not about failure. It is a recognised medical treatment for a chronic health condition — not a last resort.
Delaying surgery until all else has failed often results in more complications and poorer health. Talking to a specialist early can help you avoid years of struggle and reduce your risk of developing serious illness.
