Which symptom is commonly associated with Crohn's disease?

Weight loss is commonly associated with Crohn's disease due to the inflammation and damage it causes in the gastrointestinal tract, leading to malabsorption of nutrients and calories. Patients with Crohn's disease often experience a range of gastrointestinal symptoms such as diarrhea, cramping, and abdominal pain, which can also contribute to a decreased appetite and subsequent weight loss.

In contrast, right shoulder pain is not directly related to Crohn's disease; it might be more indicative of referred pain from abdominal issues or other unrelated conditions. A persistent cough is typically associated with respiratory conditions, not gastrointestinal disorders like Crohn's. Similarly, chest pain could arise from a variety of causes, but it is not a recognized symptom of Crohn's disease. Thus, weight loss stands out as a key indicator of the nutritional and systemic impacts that Crohn's disease can impose on a patient.
