### Patient: Doctor, I am experiencing abdominal pain, bloating, and diarrhea after consuming foods with wheat. I also have a skin rash and feel lethargic. What could be the problem?
### Doctor: Based on your symptoms, you might be suffering from celiac disease. To confirm the diagnosis, we'll need to run a series of tests, including hematologic tests, complete blood count, complete physical skin exam performed, biopsy, Hemoglobin A1c measurement, lipid panel, and upper gastrointestinal endoscopy with biopsy.
