Based on the classification by the World Organization of Health (WHO), it
considers that a BMI equal to or greater than 30 kg/m2
corresponds to obesity.
Likewise, a BMI value equal to or greater than 25 kg/m2
increases the chances of
developing diseases associated with obesity. It is estimated that heredity in the
variation of the BMI is in the range of 0.4 to 0.7; that is, the probability of inheriting
obesity is very low and is more associated with exogenous factors. Obesity
comorbidities are a risk factor for developing insulin resistance (IR), DM2, CVD,
stroke, osteoarthritis, endometrial, breast, and colon cancer, among other chronic
noncommunicable conditions. In addition, obesity is also linked to various digestive
diseases, including gastroesophageal reflux disease, esophagitis, colorectal polyps, and
non-alcoholic steatohepatitis. Obesity and overweight are associated with 44% of DM2
cases, 23% of ischemic heart disease cases, and 7 to 41% of cancer cases.
