You are a candidate for gastric bypass surgery (weight loss surgery) if you are either
· morbidly obese with a BMI* over 40
· or if you are severely obese with a BMI over 35 and have comorbid conditions like hypertension, sleep apnea, Type 2 diabetes and high cholesterol
You should be thinking of bariatric/weight loss surgeries only if you satisfy the conditions above. There are also few other key factors that you should be considering before proceeding such as:
1. Finances for the procedure: Insurance may or may not cover bariatric surgery, so it is best to check with insurance company about this.
2. Commitment to change to a regulated diet and a healthier lifestyle
3. Understanding that you may be required to take vitamin supplements for the rest of the life.
4. Meet certain medical guidelines as specified by the surgeon. Pre-surgery tests may include blood tests, ECG, ultrasound scans of the gallbladder and nutritional tests. These tests help the surgeon to determine if the patient is fit to undergo surgery.
5. Your age: Ideally the age of the patient should be between 20 and 50. If you are over 50, the doctor would most likely require a cardiac evaluation.
You should also discuss with the surgeon in detail to understand whether you a good candidate for the surgery. Do ensure that doctor is aware of all your medical problems (if there are any) and your family medical history.
*BMI or Body Mass Index is a universally accepted measure to find out a person’s relative weight index. In metric system, this is calculated using a simple formula which is kg/m2 (weight in Kilograms/square of height in metres). In Imperial system when pounds (for weight) and inches(for height) are used, a conversion factor of 703 must be applied to get the BMI which then becomes (lb/in2)*703.
