Abbreviations: BMI, body mass index (calculated as weight in kilograms divided by height in meters squared); GERD, gastroesophageal reflux disease; HDL, high-density lipoprotein; LDL, low-density lipoprotein; NAFLD, nonalcoholic fatty liver disease.

SI conversion factors: To convert glucose to millimoles per liter, multiply by 0.0555; hemoglobin A_1c to proportion of total hemoglobin, multiply by 0.01; total cholesterol, HDL cholesterol, and LDL cholesterol to millimoles per liter, multiply by 0.0259; and triglycerides to millimoles per liter, multiply by 0.0113.

^a Class 1 obesity: BMI of 30 to less than 35; class 2 obesity: BMI of 35 to less than 40; and class 3 obesity: BMI of 40 or higher.
