Vitamin B12 is found in animal products, such as eggs, meat and dairy. However, even if you do eat such foods, you might have a malabsorption issue. How can you tell? Red blood cells that grow too large become deformed and can’t function correctly. Responsible for transporting blood and oxygen around the body, red blood cells can’t do this when they’re the wrong shape.
People diagnosed with ARDS will most likely be admitted to a hospital’s intensive care unit (ICU).
NICE added that older people might experience angina if they’re suffering from a vitamin B12 deficiency.
It’s also possible for a person to experience angular cheilitis – red, swollen patches in the corners of the mouth.
Some people might develop “brown pigmentation” on their nails beds and creases in their skin.
Examples of neurological complications include:
- Loss of cutaneous sensation
- Loss of mental and physical drive
- Muscle weakness
- Optic neuropathy
- Psychiatric disturbances – these range from mild neurosis to severe dementia
- Symmetrical neuropathy affecting the legs more than the arms — this usually presents with ataxia or paraesthesia
- Urinary or faecal incontinence.
The best way to determine if you’re lacking healthy red blood cells is to go for a quick blood test at your nearest medical centre.
Your GP will get in contact with you if there is evidence of a vitamin B12 deficiency from your blood sample.
