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.

FAQ About Bariatric Surgery in New York, NY

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

There is no fixed timeframe for returning to work after bariatric surgery, but on average, most patients recover for two to three weeks before returning. A delay in returning to work is not necessarily due to 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 who work in more physically demanding occupations may require a longer healing period, such as four to six weeks. However, if feasible, arrangements can be made for an earlier return to light-duty tasks.

How much weight can I expect to lose?

The amount of weight a patient will lose depends on a wide range of variables such as genetics, the operation selected, portion sizes prior to surgery, portion sizes and food choices after surgery, exercise, and metabolic rate.

Patients who rely completely on the surgery and do not change their food choices and lifestyle behaviors will not have 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.
