4. You deal with a vitamin B12 deficiency
If you’re wondering what a vitamin B12 deficiency has to do with gastritis, note that H. pylori infection can restrain your body’s natural ability to break down the protein needed to get B12 from the foods you eat.
Vitamin B12 is crucial for maintaining good energy levels. Dairy, eggs, fish, and poultry are the best sources of vitamin B12, but if you have an H. pylori infection, it doesn’t matter how many B12 sources you consume.
So, when you left an H. pylori infection untreated, and you also struggle with a vitamin B12 deficiency, you are more likely to develop a chronic inflammatory disease called autoimmune gastritis. Any coordination issues or loss of balance indicate a vitamin B12 deficiency.
