Obesity


Obesity is excess body fat, which leads to a too high weight. Increased predisposition to many diseases and reduces life expectancy.

In normal conditions the human body is constituted, in part, by fat. They serve as an energy reserve and stored in adipose tissue cells or adipose, they are called adipocytes. In many people, there is excess fat stored, giving rise to excessive weight. Depending on the importance of this excess, speaking of overweight (slightly higher weight) or obesity (weight too high).

Forms

Obesity can start from childhood or adulthood appear. Some obese have eating disorders. In some cases it may detect a specific triggering event, which is followed by a rapid increase in weight. In other situations, Obesity is becoming progressively, for years. Adipose tissue is distributed differently from one person to another. According to the body area dominated, there are two types of obesity:

Causes

There are three important factors that may be at the origin of obesity:

Hereditary factors. Children whose parents are obese are more at risk of being than children whose parents are of normal weight. Moreover, the importance and distribution of fat tissue are determined by genetic factors. Different aspects of the assimilation of food by the body and behavior that predisposes to obesity (p. for example., likes food and fat storage capacity) also have, in part, a genetic. The investigation of the genetic factors responsible for obesity is still in its infancy. at least 20 different genes appear to be associated with it.

Dietary factors. To become obese, overeating necessary regarding the energy requirements or consuming too much fat in relation to the ability to use. This excess supply is enhanced by the quantity and nature of food available, but also by family and cultural habits that lead to eating beyond satiety. The evolution of lifestyles in industrialized countries is manifested by an increase in consumption of sugars and especially fat. Simultaneously acquiring welfare (lifts, transport and heating) helps reduce physical activity and energy expenditure.

Psychological factors. Depression, anxiety often occur, as compensation, a tendency to overeat or decrease the degree of activity.Depression, anxiety often occur, as compensation, a tendency to overeat or decrease the degree of activity.

Diet   

Obesity treatment is to maintain a balanced diet that limits the intake of calories (decrease fat intake and often sugars). This diet should be accompanied by information and nutrition education. Strict diets produce quick weight loss, but do not give the best long-term results.


Obesity is a difficult disease to treat and relapses are frequent. Treatment requires active participation of the patient, you should get medical care and long-term monitoring. Before starting the treatment, the doctor and the patient set a goal, you must be realistic and that is usually less than what the patient wants. but even moderate (the order of 10 to 15% of initial weight), any thinning is beneficial to the health of obese and significantly decreases the risk of obesity-related diseases.
