Crohn’s disease is a chronic inflammatory condition affecting the digestive system, potentially leading to serious health issues. It manifests in five distinct forms, each presenting unique symptoms and treatment pathways. The disease primarily impacts the lower small intestine and the colon, with increased prevalence among individuals aged 15 to 35, though it can affect all age groups. Crohn’s causes inflammation, thickening, or scarring of bowel tissue, resulting in blockages and ulcers. Consequently, malabsorption of nutrients occurs, impairing digestion and health.
The five key types of Crohn’s disease include:
- Crohn’s Colitis: This affects the colon, causing ulcers, fistulas, and abscesses around the anal area. Symptoms include rectal bleeding, diarrhea, joint pain, and skin issues, with discomfort ranging from moderate to severe.
- Jejunoileitis: Involving the jejunum, the upper section of the small intestine, it causes cramps after eating, fistulas near the anus, abdominal pain, and diarrhea.
- Ileocolitis: The most common form, impacting the ileum and colon, leading to weight loss, severe diarrhea, and abdominal cramps.
- Ileitis: Primarily affecting the ileum, it can cause fistulas and abscesses, similar to ileocolitis, with significant inflammation.
- Gastroduodenal Crohn’s Disease: This form targets the stomach and duodenum, with symptoms like nausea and loss of appetite, often resulting in weight loss.
