(RxWiki News) People who are stressed out for long periods of time may face a higher risk of becoming obese, according to a new study.
The researchers behind this study looked at more than 2,500 patients. They tested patients' hair for levels of cortisol, a hormone associated with stress.
Over a four-year study period, participants who had higher levels of cortisol in their hair samples were more likely to be obese than those who had lower levels of cortisol.
"People who had higher hair cortisol levels also tended to have larger waist measurements, which is important because carrying excess fat around the abdomen is a risk factor for heart disease, diabetes and premature death," said lead study author Dr. Sarah Jackson, of University College London, in a press release.
These researchers noted that their findings do not necessarily establish a cause-and-effect relationship between stress and obesity.
