The effect that obesity has on a person is wide-ranging and impacts a person’s whole life, from their health to their work. There are many assumptions and misconceptions about bariatric surgery.


Myth: Bariatric surgery is an easy fix.

Reality: Losing weight from bariatric surgery can be a relatively short process but the lifestyle changes are long term, lifetime changes that include eating healthy and daily exercise.

Myth: Bariatric surgery provides immediate results.

Reality: Weight loss is usually visible within weeks until about one year when the patient often notices they stop losing weight.  In this case, they have reached the plateau where the surgery has taken off as much weight as it can. The rest of the weight loss stems from diet and exercise.

Myth: Diet and exercise are not necessary after bariatric surgery.

Reality: Lifestyle modifications like healthy eating and exercise are essential to the success of weight loss surgery. At least 30 minutes of exercise a day and a diet high in protein and low in sugar are recommended to continue to lose weight and keep it off. Creating and maintaining healthy eating habits influences the sustainability of the weight loss. Make healthy eating and exercise a habit, a routine, a lifestyle.


Body Mass Index (BMI): BMI is the relation between height and weight.  A BMI calculator can be easily found on the web.

  • BMI 18.5-25: normal weight
  • BMI 25-30: Overweight, diet and exercise recommended
  • BMI 30-35:  Obesity, medications may be added to diet and exercise

Candidates for bariatric surgery:

  • A person with a BMI of 35 or more with one or more diseases associated with obesity, like diabetes, high blood pressure, sleep apnea, elevated cholesterol and lipids, osteoarthritis, etc.  However, a patient with a BMI of 40 or more is a candidate for bariatric surgery whether or not there are any associated diseases present.
  • The candidate must have no addictions to either drugs or alcohol.
  • The candidate should be in good health.
  • The candidate should be psychologically stable.

It is important that the candidate understands the procedure and the lifestyle changes that have to be made after the surgery.

Preparing for surgery:

Each candidate for bariatric surgery must go through a multidisciplinary preoperative evaluation to assess the patient’s overall health. The patient is evaluated by a cardiologist, a nutritionist, a psychologist, an endocrinologist and a pulmonary doctor, if necessary.


Bariatric surgery can have a deep impact on the patient’s health. Along with weight loss comes additional health benefits. Weight loss surgery can improve or even cure the diseases associated with obesity like diabetes, high blood pressure, high cholesterol, sleep apnea and bilateral knee osteoarthritis. Maintaining a healthy lifestyle after the surgery is essential. The most important impact of bariatric surgery is the overall health improvement.
