Obesity - Definition

Ask a question


Obesity is defined as when the concentration of fatty mass is too high in the body, with an increased volume of fatty tissue. It is assessed as standard by calculating the BMI, or body mass index, using the formula of weight (in kilograms) divided by height (in meters). A normal adult's BMI should fall between 19 and 25. If the value is over 25 but under 30, it is termed as overweight, and if over 30, as obese, categorized into different grades. Obesity can have serious consequences on the health, such as high blood pressure, diabetes, cardiovascular problems, and so on. The excess weight is often due to an unhealthy lifestyle (such as overeating, or insufficient physical activity), but genetic factors can also be the cause, as some people's bodies store much more fat than is normal. Treatments for obesity can take different routes, particularly implementing a specific diet or, in extreme cases, surgically implanting a gastric band, for example.
