Vitamin B12 deficiency

Vitamin B12 deficiency is quite common in IBD patients because B12 is absorbed at the end of the small intestine.

People with Crohn’s disease in this area may not be able to absorb B12 properly. People who have had surgery to remove the stomach or part of the small intestine which includes the end of the small intestine may also not be able to absorb vitamin B12. Annie and Roger talk about their lives with B12 deficiency in this video.

Vitamin B12 helps to keep the nervous system healthy and is needed to make new cells in the body.

Common symptoms of a vitamin B12 deficiency include:

• Tiredness
• Lethargy
• Feeling faint
• Breathlessness

Less common symptoms include:

• Headaches
• Heart palpitations
• Altered taste
• Loss of appetite
• Ringing in the ears (tinnitus)
• Looking pale
• Sore mouth and tongue

B12 deficiency diagnosis

If you think you may have vitamin B12 deficiency, you should see a healthcare professional. Diagnosis usually involves blood tests to measure B12 levels.

Doctors might also check for other markers like homocysteine and methylmalonic acid levels for a more comprehensive picture. It's crucial to consult with a healthcare professional for a proper diagnosis and guidance on the next steps.

B12 deficiency treatment

For B12 deficiency, the usual treatment involves B12 supplements. This can be in the form of injections or oral supplements. Foods rich in B12 like fish, meat, and dairy can also help. It's essential to consult with a healthcare professional for personalised advice based on individual health conditions.
