What is a common symptom of Crohn's Disease?

Tenesmus, which refers to the feeling of incomplete evacuation after a bowel movement or a persistent urge to have a bowel movement, is commonly associated with Crohn's Disease. This inflammatory bowel disease affects the gastrointestinal tract and can lead to symptoms such as abdominal pain, diarrhea, and changes in bowel habits. Tenesmus specifically occurs due to inflammation and irritation of the rectal area and can be quite distressing for those suffering from the condition. This symptom is a direct result of the disease's impact on the intestines, making it particularly relevant in the context of Crohn's Disease, whereas the other options do not specifically relate to the gastrointestinal symptoms commonly experienced by patients.
