Dr. Smart, you are shadowing with a gastroenterologist, someone who specializes in the digestive system. While shadowing your friend Dr. Bright, you encounter a patient with an interesting case. A 63 year old male patient names Cramer comes to the clinic in a panic. He has been waking during the night most nights due to dyspepsia or stomach pains, they also occur between meals. Pain is a burning type pain that he rates at around a 4/10. He points to his epigastric region and says that is the location of his pain. When he eats the pain subsides but then returns 2-4 hours after eating. He feels bloated after eating and has tried over the counter acid reducing medications that provide some relief.
