Sept. 7, 2011 -- Many people who were exposed to the dust cloud after the terror attacks on Sept. 11, 2001, may have developed lasting heartburn, indigestion, acid reflux, and other symptoms of gastroesophageal reflux disease (GERD).
The new findings appear in the American Journal of Gastroenterology. They bolster the results of another recent study that looked at the lingering health effects, including heartburn and acid reflux, seen among rescue and recovery workers at Ground Zero.
“This study provides more evidence to support that there could be a relationship between 9/11 exposure and GERD symptoms,” says researcher Jiehui Li, MBBS. She is with the New York City Department of Health and Mental Hygiene in Long Island City, N.Y.
Researchers surveyed more than 37,000 adults who lived or worked near Ground Zero who did not report any GERD symptoms prior to 9/11. Of these, 20% had some new GERD symptoms after 9/11. For 13%, these symptoms persisted for at least five to six years, the study showed.
The researchers speculate that alkaline cement -- one of the components seen in the dust cloud that enveloped lower Manhattan after the terror attacks - may have contributed to causing asthma and GERD.
