Signs & Symptoms

HOW CAN A B12 DEFICIENCY AFFECT US?

When a B12 deficiency occurs it can cause symptoms to manifest almost anywhere in the body. Some sufferers will show many symptoms whilst others will show no physical symptoms at all.

 

Intensity of symptoms can vary greatly from person to person. Some will experience a vague feeling of being unwell but find it difficult to describe, whilst in others their symptoms are so severe that they impact on everyday life.

 

Short, sharp stabbing pains can come and go instantaneously but other symptoms creep up over a number of years. When these occur in older people they are often just put down to old age and the B12 deficiency goes undiagnosed and untreated.

 

Some symptoms can disappear soon after treatment begins, but for most people it takes months or even years to regain full health. If diagnosis or treatment has been delayed it is quite possible for irreversible damage to have occurred.
