I was diagnosed with gastroparesis few months back but I have persistent nausea. Its all day pretty much every single day and no medicine helps. My Dr said people who have gastroparesis shouldn't persistently be nauseated. So she thinks I could have anxiety/stress which I dont think I do. I do have a small tumor on my pituitary gland which I recently looked up causes nausea... I will talk to my endocrinologist about that but at this point my gastro Dr is kinda clueless about my nausea symptom and so am I. Any help on what can be causing it?
