What is BMI

BMI is the most commonly used measurement for obesity. The BMI approximates body mass using a mathematical ratio of weight and height.

A BMI of 30 or greater is regarded by most health agencies as the threshold for obesity. A BMI of 40 or greater generally qualifies as severe obesity. However, note that BMI measurements in body-builders and athletes may not be accurate determinants of obesity because the BMI does not distinguish between muscle and fat.

Federal Guidelines for Healthy Weight

  • Underweight. Your BMI is less than 18.5.
  • Ideal Weight for Your Height. Your BMI is between 18.5 and 24.9.
  • Overweight. Your BMI is between 25 and 29.9.
  • Obesity. Your BMI is 30 or greater.

Frequently Asked Questions About Bariatric Surgery

How long do I need to take off work for Bariatric Surgery?

There is no fixed timeframe for a bariatric patient who has undergone surgery to return to work—it typically takes around two to three weeks, and sometimes longer. The potential factor causing a delay is not necessarily pain but rather a lack of strength and the challenge of adapting to a new eating routine. Moreover, any medical complications that arise can also contribute to a delay in returning to work. To ensure sufficient recovery, we recommend planning to take three to four weeks off from your job. Individuals engaged in physically demanding occupations may require a longer healing period of 4-6 weeks. However, if feasible, arrangements can be made for a return to light-duty tasks earlier.

How much weight can I expect to lose?

The amount of weight a patient will lose depends on a wide range of variables like genetic makeup, what operation selected, how much he/she typically ate before surgery, how much he/she will be able to eat after, how much exercise the patient gets and his/her metabolic rate.

Those that only rely on surgery and do not change their behavior and become more active will not have the as favorable a result.

Which operation and what approach are best for me?

In medicine, there are no absolutes and each operation has advantages and disadvantages. It is important during your consultation that you and your doctor discuss your major health problems, concerns and expectations. Your surgeon will outline a strategy that works best for you.

Which insurance plans do you accept?

Insurance acceptance follows Northwell Health, which is the largest healthcare organization in New York State and can vary based on contracts done with the entire system.
