7 Nausea, diarrhea, and vomiting

The digestive system might be adversely affected by a lack of vitamin B-12. Due to a deficiency in red blood cells, insufficient oxygen is delivered to the gut. A lack of oxygen in this area may cause a person to feel nauseous and fall ill. Most of the time, nausea causes vomiting, but diarrhea may also be a side effect.

8 Weight loss and a decreased appetite

People with vitamin B-12 deficiency may lose their appetite due to digestive issues like nausea. This makes a person even lose their appetite because whatever they ingest makes them feel uncomfortable.
