Obesity is a condition that describes a person who is overweight. It is a complex disorder of having excessive amount of body fat. It represents a big concern as it increases the risk for developing other health problems and diseases such as heart disease, high blood pressure and diabetes. Extremely obese people are more likely to develop health problems that are associated with weight. Even minor weight loss can improve the health problems or prevent possible medical conditions and diseases related to obesity. Obesity can be treated by changing the eating habits and increasing the level of physical activity. Additional treatment options can be medications and surgery.


Obesity means having too much body fat excess. Usually, obesity is diagnosed if a person has a body mass index that is 30 or higher. The body mass index or BMI can be calculated by dividing the weight in kilograms by the height in meters squared. A doctor or health provider can help in measuring a person’s BMI and further evaluation of the condition, the health risks and problems that may appear, as well as options on how to lose weight and fight obesity.
