Five diseases of the digestive system?

1. Gastroesophageal Reflux Disease (GERD)

GERD is a condition where stomach contents, including acid and bile, flow back into the esophagus. This can cause a burning sensation, pain, and inflammation.

2. Peptic Ulcer Disease

Peptic ulcer disease is a group of conditions that involve ulcers in the lining of the stomach or duodenum (the first part of the small intestine). These ulcers can cause pain, bleeding, and other symptoms.

3. Irritable Bowel Syndrome (IBS)

IBS is a functional disorder of the digestive system that affects the large intestine. It causes abdominal pain, bloating, diarrhea, and constipation.

4. Crohn's Disease

Crohn's disease is a chronic inflammatory bowel disease (IBD) that can affect any part of the digestive tract from the mouth to the anus. It causes inflammation, damage, and scarring of the digestive tract.

5. Celiac Disease

Celiac disease is an autoimmune disorder that is triggered by the ingestion of gluten, a protein found in wheat, barley, and rye. It can cause damage to the villi (small, finger-like projections) that line the small intestine, which leads to malabsorption of nutrients and a variety of other symptoms.
