Is it caused from using Stevia? I have been suffering from pain in my upper stomach, with nausea, burping, bloating, and dizziness. I feel generally unwell, I feel a raw gnawing in my stomach. H Pylori was normal. I was given an ultrasound that came back normal, however, blood work revealed my iron is low. From here, should I be scoped? And.......what do you think it may be? Can I have an ulcer without it being H Pylori?
