It sounds strange, but losing weight can also pose some health hazards, as concluded by a new study published in the International Journal of Obesity.

The researchers found that the concentration of persistent organic pollutants in the blood of people who lost weight was much higher, as compared to other persons with stabilized or increased weight.

The compounds called persistent organic pollutants (POPs) are formed in the humans during the industrial process. Theses industrial pollutants give way to disorders like type 2 diabetes, cancer, dementia, and heart disease.

Fat tissues accumulates the POPs, but when one loses weight and shuns extra fat, there are chances that these pollutants get discharged into the blood stream and effect brain and heart.

The study was carried out on 1,099 adults and analysis was done considering seven common persistent organic pollutants in them. It was found that POPs level was significant in adults, who reduced their major portion of weight. But in those who maintained their weight reduction at a steady rate for 10 years or more, comparatively less formation of POPs was experienced.

There is no clarity that if weight loss is the major reason of release of the persistent organic pollutants or there could be other obesity related factors for this. So, there is requirement of more studies to confirm the adverse effects of weight loss.
