Body Mass Index (BMI) Calculator

Body Mass Index Calculator

At A Personal Choice, patients are required to have a body mass index (BMI) of less than
37 for tubal ligation reversal and 45 for vasectomy reversal at least 3 weeks prior to the date of surgery. This policy is for optimal patient safety when undergoing elective outpatient surgery.


Body mass index (BMI) is a calculation based on height (without shoes) and weight that correlates with the amount of body fat. Calculating your BMI will tell you if you are at a healthy weight. To use this calculator:

Step 1: Enter your weight in pounds 

Step 2: Enter your height measured without shoes. Height must be entered in inches only.

For metric measurements (kg and cm) use: Metric Calculator

Your height and weight will be measured on the day of your surgery consultation. Using the measurements obtained at the time of your consultation, your BMI will be officially calculated. If your BMI is over our maximal limit then your surgery will be canceled.

Is your BMI over 37 (women) or over 45 (men)?

If your body mass index is higher than the maximal limit, we recommend progressive weight loss through diet combined with regular exercise such as walking daily. Fasting, limiting fluid intake, or using diuretics to lose weight immediately before surgery should be avoided to minimize the risks of surgery and anesthesia.

It is essential that you provide accurate information regarding your height and weight when scheduling surgery and during your anesthesia consultation. Providing inaccurate information about your height and weight, past surgery, or medical conditions may result in your procedure being rescheduled or cancelled.
