Is duodenal bulb inflammation contagious?

Duodenal bulb inflammation is not contagious. Duodenal bulb inflammation is a non-specific infectious disease belonging to digestive system disorders. It does not involve pathogens typically associated with contagious diseases, such as bacteria, viruses, or mycoplasma; therefore, it cannot be transmitted to family members through contact, air, food, or other routes. This condition is usually caused by factors such as excessive gastric acid secretion, Helicobacter pylori infection, long-term alcohol consumption, smoking, or the use of certain medications. Symptoms include upper abdominal pain, nausea, vomiting, and acid reflux. Treatment generally involves taking medications orally as directed by a physician to inhibit gastric acid secretion and protect the gastric and duodenal mucosa. If duodenal bulb inflammation is associated with Helicobacter pylori infection, the bacteria can be transmitted via the oral-oral route; however, this does not imply that duodenal bulb inflammation itself is contagious.
