Everything you need to know about this condition
What is Crohn's disease of large intestine with fistula?
Crohn's disease of the large intestine with fistula is a type of inflammatory bowel disease (IBD) that affects the large intestine, also known as the colon. It is characterized by chronic inflammation and irritation of the colon, which can lead to the development of fistulas, or abnormal connections, between the colon and other organs or the skin. This condition can cause a range of symptoms, including diarrhea, abdominal pain, weight loss, and fatigue.
Causes and Risk Factors
The exact cause of Crohn's disease is not known, but it is believed to be the result of a combination of genetic, environmental, and immune system factors. According to the World Health Organization (WHO), people with a family history of IBD are more likely to develop Crohn's disease. Other risk factors include smoking, a diet high in processed foods and sugar, and a lack of physical activity. Additionally, people with certain genetic mutations, such as NOD2/CARD15, are more likely to develop Crohn's disease.
Signs and Symptoms
The symptoms of Crohn's disease of the large intestine with fistula can vary from person to person, but common signs and symptoms include:
- Diarrhea, which may be bloody
- Abdominal pain, which may be crampy or constant
