Upper Gastrointestinal Conditions: Nonmalignant Conditions of the Stomach.

Functional dyspepsia can be categorized into two syndromes: postprandial distress syndrome and epigastric pain syndrome. infection is one of the most common chronic infections worldwide. Acute infection causes dyspepsia, and chronic infection can cause peptic ulcer disease. also is one of the causative agents in gastric adenocarcinoma and mucosa-associated lymphoid tissue lymphoma. The incidence of infection varies among different ethnic populations and geographic locations. Screening for and eradication of infection in healthy asymptomatic high-risk individuals has reduced the incidence of gastric cancer significantly. eradication is the first-line treatment in patients with low-grade mucosa-associated lymphoid tissue lymphoma and may be curative. The monoclonal fecal antigen test and urea breath test identify active infection, confirm eradication, and have high negative and positive predictive values regardless of prevalence. Decreasing outpatient usage of antibiotics decreases resistance. The American Society for Gastrointestinal Endoscopy recommends screening for premalignant lesions in the stomach only in patients with a family history or from a high-risk ethnic group. Gastroparesis is a debilitating condition that requires care from a multidisciplinary team that can offer different management modalities.
