Weight loss surgery is becoming more common around the world, yet many misconceptions still circulate. These myths can create fear, confusion and unnecessary hesitation. Here are ten of the most common myths, and the truth behind them.
Myth 1: “Weight loss surgery is the easy way out.”
Surgery is not a shortcut. Patients still have to follow a structured eating plan, eat mindfully and stay active. The procedure is only a tool, and long-term success depends on healthy habits and consistent lifestyle changes.
Myth 2: “I will lose weight automatically after surgery.”
Most patients lose a significant amount of their excess weight, but this takes effort. Without regular exercise and healthy eating, some weight can return. The surgery changes your anatomy, but old habits can still bring the weight back over time.
Myth 3: “Weight loss surgery is cosmetic.”
This is not a cosmetic procedure. Weight loss surgery improves or even resolves conditions such as high blood pressure, type 2 diabetes, sleep apnoea and infertility. This is why it is also known as metabolic surgery.
Myth 4: “You have to be extremely heavy to qualify.”
Eligibility is not based on weight alone. Patients with a BMI of 30 to 35 may qualify if they have a condition such as type 2 diabetes or high blood pressure that would improve with surgery. It is your overall health, not a single number, that determines suitability.
Myth 5: “Recovery takes months.”
Recovery is often faster than people expect. Most patients return to everyday activities within one to two weeks, and many go back to work within a few weeks, depending on their job.
Myth 6: “If you are very ill, you cannot have surgery.”
Often, surgery is recommended precisely because a patient is very ill. Conditions such as heart failure, chronic lung disease, type 2 diabetes and high blood pressure can all improve significantly after weight loss. In some cases, a gastric balloon may be used first to help a patient lose some weight before surgery, which lowers the risk during the operation. This is more common at very high BMIs.
Myth 7: “You have to stay in hospital for a long time.”
Hospital stays are short. After laparoscopic (keyhole) surgery, most patients go home within a few days.
Myth 8: “I am too old for weight loss surgery.”
Age alone is not a barrier. If a patient can benefit medically from a gastric sleeve or gastric bypass, and there are no serious contraindications, surgery can still be a suitable option later in life.
Myth 9: “You will never eat normally again.”
Portions are small at first, and food choices need care in the early months. But over time, portion sizes increase and eating becomes normal again. Patients can still enjoy social events, family meals and celebrations, with the pleasure coming from flavour rather than quantity.
Myth 10: “Health insurance never pays for weight loss surgery.”
If the medical criteria are met, many insurers do cover the procedure. Clear guidelines set out when cover is approved, so that patients with a genuine medical need can get support.
