According to a pilot study published in the medical journal Acta Dermato-Venereologica by Dr. Camilo Diaz and colleagues in England, there may be a relationship between the bumps (papules) and pimples (pustules) of subtype 2 rosacea and infection with Helicobacter pylori bacteria.1
In the study of 49 rosacea patients, 46 percent who had subtype 2 rosacea tested positive on a breath test for the presence of H. pylori. This compared with only 25 percent of the patients with subtype 1 rosacea, characterized by redness and sometimes visible blood vessels.
