Carrying extra body weight, especially around your middle, raises your risk for heartburn. So how do you know if you’re at risk? A BMI (body mass index) higher than 24 is considered overweight. BMI is a gender-free measurement that relates height to weight. To find out your BMI:
BMI = (W/H2) × 705
Translation:
Your weight (in pounds)
Divided by your height (in inches, squared)
Multiplied by 705
