What does it mean to have polyps in the stomach?

The development of gastric polyps is not attributable to a single, specific cause. Current understanding suggests that gastric polyps are associated with several factors, including long-term smoking, chronic gastric inflammation, Helicobacter pylori infection, and genetic predisposition. Gastric polyps primarily represent localized, exophytic hyperplastic changes of the gastric mucosa. In most cases, such polyps are benign. If asymptomatic, they typically require no treatment, and observation alone is considered safe and appropriate.

In the early stages, gastric polyps are usually asymptomatic. However, as they grow larger, patients may experience upper abdominal pain or distension; some may develop nausea and vomiting. If a polyp becomes complicated by ulceration or erosion, gastrointestinal bleeding may occur.

Clinically, the most common presenting signs are melena (black, tarry stools) or positive fecal occult blood tests; hematemesis (vomiting blood), however, is rare.

Regarding management: polyps smaller than 2 mm generally require only surveillance, with repeat gastroscopy recommended every 6–12 months. Polyps measuring 3–5 mm—or up to 8 mm—typically warrant endoscopic polypectomy, commonly performed using a snare device. This minimally invasive procedure entails minimal trauma and rapid recovery, with most patients discharged within 3–5 days. Larger polyps that infiltrate the submucosal layer—or those showing evidence of malignancy—may necessitate surgical resection.
