E66: Obesity

E66.0: Obesity due to excess calories

Obesity due to excess calories, designated by the ICD-10 code E66.0, is a medical condition characterized by the accumulation of excessive body fat. This type of obesity is a result of an imbalance between caloric intake and energy expenditure, where the consumed calories exceed the number of calories the body burns. Common signs include a Body Mass Index (BMI) of 30 or higher, increased waist circumference and excessive body weight. Progression may lead to a myriad of health issues such as heart disease, type 2 diabetes, high blood pressure, and certain types of cancer. At the heart of this condition is the digestive system, which absorbs the nutrients and calories from food. However, every part of the body may be adversely influenced by obesity as it hinges on various functions and health indicators.
