Vitamin B12 deficiency gradually worsens over time, leading to an increase in seemingly harmless symptoms.
However, because the nutrients are essential for the formation of healthy blood cells, the damage may become permanent.
Deformed red blood cells cause less oxygen to be transported throughout the body, and as everyone knows, oxygen is vital for survival. A lack of healthy blood cells first appears as signs of anemia, so pay attention to your color.
The NHS has confirmed that ‘pale skin’ is a warning sign of anemia.
Another typical symptom of having fewer healthy red blood cells is “hearing sounds from inside the body, not from an outside source.”
This is known as tinnitus, which is when you think you can hear something that no one else can hear.
The sound can be a ringing, a buzzing or a buzzing sound; For some, the condition can cause hissing, palpitations, or musical melody.
“You may hear these sounds in one or both ears, or in your head. They may come and go, or you may hear them all the time,” the NHS said.
There are specific symptoms of anemia caused by vitamin B12 deficiency (rather than the general symptoms of anemia that can also appear).
For example, a sore and red tongue — known as glossitis — indicates that your body lacks enough vital nutrients.
Another clue to a vitamin B12 deficiency is when you get mouth ulcers. Ulcers appear on the inside of the mouth, most notably on the cheeks, lips, or even the tongue.
Vitamin B12 deficiency can affect the eyes, where it can cause “vision disturbance”.
And many symptoms can be reversed – if treated early enough with vitamin B12 supplements.
However, the longer you leave symptoms, the more permanent they become.
People diagnosed with a vitamin B12 deficiency, after a blood test, are likely to recommend B12 injections.
