Adelaide researchers have advised doctors to closely examine the link between depression and obesity in patients because the two health problems are strongly related.
Dr Evan Atlantis, the University of Adelaide's School of Medicine, said patients with symptoms of common mental illness should be considered for obesity and related chronic diseases, and vice versa.
The lead author of the editorial published in the British Medical Journal said: "A better understanding of the mechanisms for the apparent bi-directional risk between obesity and common mental disorders is needed for effective treatment and prevention.
"Obesity may constitute a chronic stressful state, which in turn can cause significant physiological dysfunction. Such dysfunction would then predispose individuals to depressed mood and associated symptoms."
The editorial offered remarks on a new research paper on the topic published in the same issue of the BMJ by Professor Mika Kivimaki from University College London.
