Symptoms:
- Fatigue
- Weakness
- Shortness of breath
- Pale skin
- Headaches
- Dizziness
- Numbness or tingling in hands and feet
Diagnosis:
- Blood tests (e.g., complete blood count, vitamin B12 level)
- Physical examination
- Medical history
Treatment:
- Dietary changes (e.g., increasing animal product consumption)
- Supplements (e.g., vitamin B12 injections, oral tablets)
- Addressing underlying causes (e.g., managing celiac disease)
Complications:
- Anemia
- Nerve damage
- Increased risk of cardiovascular disease
- Increased risk of neurological disorders (e.g., dementia, multiple sclerosis)
Prevention:
- Ensure adequate dietary intake
- Consider supplements if necessary (e.g., vegans, vegetarians)
