- Pseudomembranous enterocolitis / pseudomembranous colitis – inflammation of the intestinal mucosa, which usually occurs after taking antibiotics; the cause is an overgrowth of the intestine with the bacterium Clostridium difficile.

- Crohn’s disease – chronic inflammatory bowel disease; it usually progresses in episodes and can affect the entire digestive tract; characteristic is the segmental affection of the intestinal mucosa, that is, several intestinal sections may be affected, which are separated by healthy sections.
- Whipple’s disease – rare systemic infectious disease; caused by the gram-positive rod bacterium Tropheryma whippelii (from the actinomycete group), which can affect various other organ systems in addition to the obligately affected intestinal system and is a chronic recurrent disease; symptoms: Fever, arthralgia (joint pain), brain dysfunction, weight loss, diarrhea (diarrhea), abdominal pain (abdominal pain), and more.
- Food allergy
- Irritable bowel syndrome (irritable colon)
