### Patient: I have been experiencing difficulty swallowing and regurgitation of food for a while now. I am concerned it may be something serious.
### Doctor: Based on your symptoms, I would recommend that we perform an upper gastrointestinal endoscopy with biopsy to check for any abnormalities in your esophagus. Additionally, we will need to conduct a radiographic imaging procedure, including a plain x-ray, as well as complete liver function tests and glucose measurement. If necessary, we may also need to perform an electrocardiogram to evaluate your heart's function. Depending on the results, we may also consider esophageal dilatation.
