Obesity destroys the brain


Obesity destroys the brain 

Obesity provokes the development of inflammatory processes in the brain in adolescents, scientists from the University of São Paulo (Brazil) found out.
The problem of obesity among young people and adolescents in developed countries is becoming more serious every year. According to the WHO, in 1990 there were 32 million children under five who were overweight or obese in the world, and in 2016, already 41 million.

Usually, obesity is associated with the development of type 2 diabetes, cardiovascular diseases, and diseases of the musculoskeletal system. However, experts identified another risk.

As part of a new study, scientists tried to better understand the possible consequences of being overweight. In the analysis, they used diffusion-tensor visualization. This is the direction of MRI, which tracks the diffusion of water along the brain tracts of white matter - a component of the central nervous system.

A total of 59 teenagers participated in the experiment, and all of them were obese.

“The brain changes found in obese adolescents are associated with important areas that are responsible for controlling appetite, emotions and cognitive functions,” the scientists noted.

It turned out that with obesity in humans, the brain's response to leptin decreases - a hormone that regulates energy metabolism. It suppresses appetite, but a decrease in its concentration contributes to obesity.
With obesity, inflammatory processes occur in the brain that are responsible for regulating food intake, which further contributes to the collection of extra pounds.
