K55-K64: Other diseases of intestines

The term "Other diseases of intestines" refers to a group of conditions that affect the intestinal part of the digestive system, which includes the small intestine and large intestine (colon). These conditions can result from various causes such as reduced blood supply (ischemia), infection, abnormal muscle or nerve function, and developmental dysfunctions. Common symptoms among these conditions include abdominal pain, nausea, constipation, diarrhea, weight loss, and rectal bleeding. The progression of these diseases varies greatly; some may resolve spontaneously or with targeted therapies, while others can lead to serious complications if left untreated, such as malnutrition, intestinal obstructions or perforations, and increased risk of intestinal cancer. The affected system is primarily the digestive system, which can result in malabsorption of nutrients and disruption in normal digestion process, additionally impacting overall health and wellness.
