Until recently, medical scientists believed that ulcer was solely caused by an overproduction of digestive fluids at the level of the stomach. Considering that stomach and duodenal ulcers occurred as a consequence of excessive acidity, doctors commonly prescribed antacids as a main form of treatment for gastric disorders. However, these medications alone were unable to completely overcome ulcer and medical scientists had to come up with more reliable drugs. In their attempt to find a better cure for ulcer, scientists have revealed new aspects of the disorder, findings that suggested the involvement of various other factors in the occurrence of digestive disorders.
In the 80s, the findings of Robin Warren and Barry Marshall revealed that ulcer was in fact caused by infection with bacteria. At that time, the discovery came as a great surprise for medical science, and most physicians denied the implication of bacteria in the occurrence and development of ulcer. Scientists believed that bacteria couldnt populate the interior of the stomach, as it was a very acidic and hostile environment, inappropriate for the proliferation of infectious microorganisms. However, the...
