gut disease refers to any medical condition or disorder that affects the gastrointestinal tract, which includes the stomach, intestines, liver, and other associated organs involved in digestion and nutrient absorption. These diseases can range from inflammatory conditions like Crohn's disease and ulcerative colitis to infections, functional disorders such as irritable bowel syndrome (IBS), and more severe conditions like colorectal cancer. Symptoms may vary depending on the specific disease but commonly include abdominal pain, diarrhea, constipation, bloating, and changes in bowel habits.
