A worrying number of Britons are caught in the grip of B12 deficiency with no end in sight
It is 2014 and Vickie wakes up in the middle of the night to find she's soaked in sweat.
It would take years and endless missed opportunities before she would learn the truth behind her symptoms: she was living with B12 deficiency.
Vickie's story is not unique: an untold number of Britons are suffering in silence as they seek out answers and ways of treating their B12 deficiency.
The symptoms are non-specific and the causes are manifold, which makes it fiendishly difficult to diagnose.

B12 performs several important functions in the body, including keeping the nervous system healthy, so becoming deficient in it can cause many problems.

"It was so bad that I had to get up regularly through the night to dry my body and bed," she told online patient community The B12 Society
Chronic fatigue and severe pain in her stomach soon followed.

"I came home and did as much research as I could on B12 deficiencies and pernicious anaemia and found out it runs in my family," she said.
Pernicious anaemia is an autoimmune condition that affects your stomach. It is the most common cause of vitamin B12 deficiency in the UK.
Unfortunately for Vickie, a test for pernicious anaemia came back negative but she remains determined to find the cause.
"I finally feel I have found a doctor who will listen and is willing to try everything to find out what has caused my deficiency. I will continue to fight for my own health, all thanks to the amazing files and group of people from the charity," she said.
How is B12 deficiency treated?
The treatment for vitamin B12 or folate deficiency anaemia depends on what's causing the condition.
Most people can be easily treated with injections or tablets to replace the missing vitamins.
