I had the same experience – B-12 deficiency caused by having become an accidental vegetarian. The individual in this story likely had other causes – however the point is that B-12 deficiency is a very serious health problem.

For some years, Burchell had been grappling with debilitating brain fog and fatigue. She was concerned it was a sign of dementia or a brain tumour, but wasn’t getting any answers from her GP.

A few days later Burchell had a referral appointment with a haemotologist, and with the train driver’s words in her head, she told the doctor she was not leaving until things were sorted. Soon after she was diagnosed with pernicious anaemia, an autoimmune condition that affects your stomach and is the most common cause of vitamin B12 deficiency.

I thought my brain fog was dementia until I discovered it was a vitamin deficiency
