Most people infected with H. pylori never experience any symptoms or complications, but will have a 10% to 20% risk of developing peptic ulcers or a 0.5% to 2% risk of stomach cancer. [ 8 ] [ 65 ] H. pylori induced gastritis may present as acute gastritis with stomach ache , nausea , and ongoing dyspepsia (indigestion) that is sometimes ...
Gastritis caused by H. pylori infection is termed Helicobacter pylori induced gastritis, and listed as a disease in ICD11. [6] [7] More than 80% of individuals infected with the bacterium are asymptomatic and it has been postulated that it may play an important role in the natural stomach ecology. [17]
The role of H. pylori in functional dyspepsia is controversial, and treatment for H. pylori may not lead to complete improvement of a patient's dyspepsia. [6] However, a recent systemic review and meta-analysis of 29 studies published in 2022 suggests that successful treatment of H. pylori modestly improves indigestion symptoms. [18]
Helicobacter heilmannii s.s. (H. heilmannii s.s.) is a species within the Helicobacter genus of Gram negative bacteria. [1] Helicobacter pylori (H. pylori) is by far the best known Helicobacter species primarily because humans infected with it may develop gastrointestinal tract diseases such as stomach inflammation, stomach ulcers, duodenal ulcers, stomach cancers of the non-lymphoma type, and ...
It can be caused by persistent infection with Helicobacter pylori, or can be autoimmune in origin. Those with autoimmune atrophic gastritis (Type A gastritis) are statistically more likely to develop gastric carcinoma (a form of stomach cancer), Hashimoto's thyroiditis, and achlorhydria.
Causes of constipation may include faecal impaction and bowel obstruction, which may in turn be caused by ileus, intussusception, volvulus. Inflammatory bowel disease is a condition of unknown aetiology, classified as either Crohn's disease or ulcerative colitis , that can affect the intestines and other parts of the gastrointestinal tract.
Noninvasive urea breath tests or stool antigen testing for H pylori should be performed on these patients. [15] People who have chronic symptoms should be considered candidates for endoscopy. Gastric biopsies should also be taken, and if H pylori is found, treatment for the infection should begin. [59] [60]
Stomach cancers usually occur due to fluctuations in acidity level and may present with vague symptoms of abdominal fullness, weight loss and pain. The actual cause of stomach cancer is not known but has been linked to infection with Helicobacter pylori, pernicious anemia, Menetriere's disease, and nitrogenous preservatives in food. [4]
