What symptoms are common in the gastrointestinal ROS?

The chosen answer highlights symptoms that are directly related to the gastrointestinal system, which is what the review of systems (ROS) in this context focuses on. Common gastrointestinal symptoms include issues such as pain associated with eating, which can indicate conditions like gastritis or peptic ulcers, and changes in bowel habits, which can reflect various disorders ranging from irritable bowel syndrome (IBS) to inflammatory bowel disease (IBD).

In evaluating the other options, they are linked to different organ systems. Joint swelling and stiffness pertain to the musculoskeletal system and may indicate arthritis or other rheumatic conditions. Muscle cramps and twitching relate to neuromuscular issues, while sensitivity to noise and ear pain are associated with auditory or neurological evaluations. Therefore, the correct choice relates specifically to symptoms indicative of gastrointestinal concerns.
