Peptic Ulcer DiseasePeptic Ulcer Disease
A peptic ulcer is a break (an ulceration) in the protective mucous lining (mucosa) of the lower esophagus, stomach or duodenum

Common MisconceptionsCommon Misconceptions
A peptic ulcer is NOT: A stress ulcer Chronic gastritis (a symptom as well as a disease state
that may lead to peptic ulcers) Dyspepsia (the symptoms that may or may not be
diagnosed as an ulcer)
Peptic Ulcers cannot be diagnosed solely on the basis of clinical presentation (Werdmuller et al. 1996)

Dyspepsia - Definition
A group of symptoms which alert clinicians to consider disease of the upper gastrointestinal tract
(British Society of Gastroenterology, 1996)(British Society of Gastroenterology, 1996)

Peptic Ulcers and StressPeptic Ulcers and Stress
Experimental stress results in decreased upper gastrointestinal blood flow in animals
(Kauffman, 1997; Livingston 1993)
Effect of stress seems to be reversible (Levenstein et al., 1996)

Peptic Ulcer and PersonalityPeptic Ulcer and Personality
Studies have found a strong association between dependency and peptic ulcers
Patients with peptic ulcer have significantly more personality disturbances than control subjects (Feldman et al.)
Ulcer patients also more inclined to pessimism and excessive dependence (Akram et al.)

Human Studies.Human Studies.Comparative evaluation of Sucralfate &
Cimetidine efficacy in treatment of chronic erosive gastritis.
The results of patients with chronic erosive gastritis treated with Sucralfate & Cimetidine were compared. The result of examinations indicate that chronic erosive gastritis is difficult to be heal; Sucralfate proved to be more efficient than Cimetidine.

Glycosulfatase activity of H. Pylori towards human gastric mucin; effect of Sucrafate.
Results demonstrate that H. Pylori, through its Glycosulfatase activity affects the sulphated mucin & glycero-gluco-lipid content of the protective mucous layer & that anti-ulcer drug Sucralfate is able to counteract the detrimental action of this enzyme.
