8. Digestive Discomfort That Lingers
Bloating, reduced appetite, or occasional diarrhea can sometimes appear alongside other signs. While digestive issues have many triggers, certain nutritional shortfalls—including B12—have been observed in connection with changes in gut comfort or appetite.
This sign often flies under the radar because it overlaps with so many other common experiences.
Here’s a quick summary of these eight signs for easy reference:
- Tingling or numbness in hands, feet, or legs
- Thinning hair or increased shedding
- Mouth sores or cracks at lip corners
- Feeling unusually cold in hands and feet
- Brain fog, memory issues, or mood changes
- Pale or slightly yellowish skin
- Muscle weakness or balance difficulties
- Persistent digestive discomfort or low appetite
