Abstract:
We hypothesised that long-term inhibition of gastric acid secretion may be associated with increased frequency of colon polyps (CP) and colorectal cancer (CRC). In a case-control study using the inpatient datafile of the Centres for Medicare and Medicaid Services (CMS), we examined the concurrence of CP or CRC with non-erosive reflux disease (NERD), erosive oesophagitis (EE), Barrett's oesophagus (BE) and eosinophilic oesophagitis (EoE) in identical patients. The total CMS population comprised 6,462,321 individual patients. CP and CRC were significantly associated with EE, NERD and BE. Our results suggest that reflux disease is associated with an increased risk for colonic neoplasia.

Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...
