Halitosis Could be Sign of Ulcer Bug Infection
 (London, Reuters Health, 1/31/03)

Dr. Ender Serin and colleagues at Baskent University in Turkey, treated 148 people who had bad breath and dyspepsia, a form of indigestion. The researchers initiated therapy to eradicate H pylori infection in the subjects' intestinal tracts and then, four weeks later, evaluated the results. The doctors found that many of the subjects said that their halitosis (bad breath) was now gone, which raised the possibility that bad breath may be a marker for H. pylori, the bacteria that is associated with ulcers.
