I have achlorhydria. My stomach ph levels are 7.5. I have developed b-12, iron, and vitamin d deficiencies. I inject 1000mcg of cobalamin daily, take 27 mg iron along with vitamin d supplements daily. I have a history of carcinoid tumors (located only in the stomach) and go for annual endoscope to have them resected. My gastrin level typically exceeds 2000. I have daily nausea and have developed neurological problems such as balance issues and neuropathy. I also have severe weakness especially my legs. I currently take Creon to aid in my digestion but this falls short since I have bought a of loose stools which are fatty and very smelly. I m not sure what else I can do to manage my symptoms better. Any incite would help.
