What causes gastrointestinal polyps?

The cause of gastrointestinal polyps is not clear for the time being. It may be caused by genetic factors, chronic inflammation stimulation, bile reflux and other reasons.

1. Genetic factors

If there is a history of adenomatous polyps in family members, the incidence of gastrointestinal polyps in other family members is higher.

2. Chronic inflammation stimulation

patients with chronic gastritis, ulcerative colitis, Crohn's disease and other diseases will also lead to gastrointestinal mucosal damage. After repeated stimulation of gastrointestinal mucosa damage, polypoid protrusions will form.

3. Bile reflux

gastrointestinal motility decreases, bile reflux in duodenum repeatedly stimulates gastric mucosa, which will also lead to gastric polyps.
