Welcome to Cancer Chat, Dreaming79.

I'm sorry to hear that you're concerned about what the levels of your B12 might mean. Unfortunately, we're not doctors here so I'm afraid you'll need to speak with your medical team in order to find that out.

In the meantime, if you feel that speaking with someone else with a medical background might help, feel free to reach out to our nurses and ask any question you might have. They're available on this phone number 0808 800 4040, Monday - Friday between 9 a.m. - 5 p.m.

Best wishes,

Hi , I too have a b12 deficiency, I have Addison pernicious anemia, which basically means , my body doesn't absorb b12 , it caused me to get numbness and tingling in legs feet and hands , extremely tired and feel very low .I get heart palpitations and irregular heart beat ,  It is hard to diagnose until you have tried iron medication, and nothing works , they took me into hospital for tests , then they found the problem, I had b12 injections every week to build up . I now get them every three month at the doctors. They make a massive difference. The doctor told me , years and years ago , people died , because not enough iron for their organs , that's what pernicious means . Deadly, it sounds scarier than it is , they will hopefully get you sorted . Hope this helps .   Try not to over think . I know that's easy to say , but stay positive and take care . Keep in touch if it helps to talk .
