H. pylori Might or Might Not Trigger Rosacea

Limited studies have suggested that a bacterium commonly associated with peptic ulcers and other gastric disorders, called Helicobacter pylori, may play a role in triggering rosacea in some patients.

Evidence of H. pylori was found in 19 of 20 rosacea patients in one study and in 26 of 31 rosacea patients in another, according to Dr. Richard B. Odom, chairman of dermatology at the University of California at San Francisco.
