BMI Calculator

Health dangers due to obesity

These risks are associated with overweight and obese adults

Adults whose BMI is larger than 25 (overweight) or whose BMI is over than 30 (obese) have an elevated risk for many diseases and health conditions, including,:

• Hypertension (elevated blood pressure)
• Dyslipidemia (increased LDL cholesterol, reduced HDL cholesterol)
• Diabetes mellitus type 2 (high blood sugar)
• Coronary heart disease (plaque build-up along the inner walls of the arteries of the heart)
• Stroke (loss of brain function due to a disturbance in the blood supply to the brain)
• Gallbladder disease (gallstones, disruption of bile functions )
• Osteoarthritis (degenerative joint disease)
• Sleep apnea and respiratory problems (problems breathing during sleep, chest and lung problems)
• Some cancers (endometrial, breast, and colon)

Explanation

Body Mass Index Prime is method of using the results of the BMI calculations to quickly and easily rank a person into a category. Eg:

• BMI Prime less than 0.74 = Underweight.
• BMI Prime greater than 0.74 and less than 1.00 = Optimal weight.
• BMI Prime greater than 1 = Overweight

Calculate your BMI and tell you if you are underweight, overweight or if your weight is optimal. Just enter your vital statistics and click the button. The results will be graphed out for you.

How it's calculated

The formula below is used to measure BMI

• BMI = weight(kilograms) / height² (metres²)         (Metric Units)
• BMI = 703 . weight(pounds) / height² (inches²)         (Imperial Units)

BMI limitations

BMI is proportional to the mass and inversely proportional to the square of the height. So, if all body dimensions double, and mass scales naturally with the cube of the height, then BMI doubles instead of remaining the same. This results in taller people having a reported BMI that is uncharacteristically high, compared to their actual body fat levels.
