Background:
The association between Helicobacter pylori infection and overweight, as one of the most common health issues, remains controversial. In this study, we systematically reviewed the effect of H. pylori infection and overweight to get a reliable answer.
Methods:
We used the Preferred Reporting Items for the Systematic Review and Meta-Analysis statement. We searched the association between H. pylori and overweight infection in international databases including Medline, Web of knowledge and Scopus, without any limitations of language, publication type, and publication status in search step of this systematic review from 2000 to 2020. We surveyed the title, abstract and full text of each research studies, and we used Newcastle-Ottawa quality for assessing the quality of each paper. A random effects model was used to calculate the pooled odd ratio with 95% confidence intervals.
Results:
Fifteen papers were eligible for this review. The selected studies reported different Odd Ratio between overweight and H. pylori infection but Odds Ratio (95% confidence interval) in our systematic and meta-analysis study was estimated at 1.42 (95% CI; 1.12, 1.81) and it was statistically significant (P: 0.003).
Conclusion:
H. pylori infection is significantly associated with overweight, therefore, the eradication of H. pylori infection is suggested because this infectious might be resulted in overweight.

Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...

An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.

Few clinical manifestations differentiate gastric ulcers from duodenal ulcers. Distinctions in the location, timing, and pain relief are crucial for healthcare providers in differentiating between gastric and duodenal ulcers during clinical assessments.
01:17Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
