The Centers for Disease Control define Body Mass Index (BMI) as a number calculated from a person’s weight and height used as a fairly reliable indicator of body fatness for most people. CDC uses Body Mass Index as a screening tool to identify possible weight problems for adults. If you have a calculated BMI in one of the ‘risk’ ranges, you may want to contact a healthcare provider to perform further assessments to determine if your excess weight is a health risk. Weighing too much may increase your risk for developing many health problems including: pregnancy complications, fatty livery disease, gallbladder disease, osteoarthritis, sleep apnea, metabolic syndrome, coronary heart disease/stroke, and type 2 diabetes.    Use our bmi calculator to calculate your body mass index.  If you have more questions about BMI, take a look at the BMI questions page.
