Exposure to the defoliant herbicide Agent Orange during the Vietnam War may be raising blood pressure levels for the aging veterans of that conflict. This was reported by a panel of the U.S. Institute of Medicine.
Two recent studies of Vietnam veterans who handled Agent Orange and other defoliants indicated that these veterans have higher rates of high blood pressure.
This report is the first step in a process used by the government to determine which health problems are connected to war service and therefore qualified for veteran’s health benefits.
If the government decides that Agent Orange is a cause of high blood pressure, it could entitle up to an estimated 3 million Vietnam veterans to health care benefits they did not previously have.
The IOM, an arm of the National Academy of Sciences, has been studying the effects of the herbicide Agent Orange on veterans since the early 1990s.
"In two new studies, Vietnam veterans with the highest exposure to herbicides exhibited distinct increases in the prevalence of hypertension; the prevalence of heart disease was also increased," the report found, although the IOM committee stopped short of suggesting that wartime exposure to Agent Orange is currently raising veterans' risk of ischemic heart disease.
The panel, which reviewed about 350 epidemiological and animal studies, also pointed to evidence linking those chemicals to AL amyloidosis, a rare disease in which protein builds up around organs. Those findings add both conditions to a list of Agent Orange-linked health problems that already includes several rare cancers, type II diabetes and birth defects in the children of the veterans exposed.
