What is a common symptom of Crohn's disease?

Crohn's disease is an inflammatory bowel disease that can affect any part of the gastrointestinal tract, and its symptoms can vary widely among individuals. Abdominal pain is one of the hallmark symptoms of Crohn's disease, often resulting from inflammation and ulceration in the intestines. This pain can be chronic and may be accompanied by other gastrointestinal issues like diarrhea or weight loss.

Joint pain is also a common manifestation associated with Crohn's, as the inflammation can extend beyond the intestines and cause arthritis-like symptoms in the joints. This is due to the systemic nature of the inflammatory response in Crohn's disease, which can affect various tissues in the body.
