It's good to run an up-to-the-head endoscopy with tissue tests to check the loss of the esophagus according to the symptoms. You also need to do radiation scans, liver function, and blood sugar measurements, including regular X-rays. If necessary, you may need to do an E.G.G. test to evaluate the heart function.
It's been hard to swallow food, it's been a while before, and it's been refluxing, and I'm worried about whether it's a serious disease or not.
