A 36-year-old man complains of frequent bouts of diarrhea, especially after consuming meals. He states he also suffers from intermittent abdominal cramps and bloating. He does not report any blood in the stool, fever, or unintentional weight loss. What could be the diagnosis?
This patient's frequent postprandial diarrhea, abdominal cramps, and bloating suggest Irritable Bowel Syndrome with Diarrhea (IBS-D). This form of IBS is characterized by loose or watery stools and can be exacerbated by certain foods or stress. It's crucial to rule out other causes of these symptoms, including food intolerances, infections, and other gastrointestinal disorders.
