Which specialist treats vitamin B12 deficiency?

Vitamin B12 is needed for healthy blood cells and normal nerve function. A clinician can review your symptoms, diet, medicines, medical history, and blood results. They may look for reduced intake, difficulty absorbing B12, or an underlying digestive or immune-related condition. Referral to a gastroenterologist may help when absorption is a concern, while a haematologist or neurologist may be involved for anaemia, unusual blood results, or nerve symptoms.

Book an appointment if you have persistent fatigue, dizziness, tingling, numbness, balance changes, a sore tongue, or difficulty concentrating. Take details of supplements you already use and a list of regular medicines. Treatment depends on the cause and may include dietary advice, tablets, or a vitamin B12 injection. Follow the clinician's plan for repeat tests and do not rely on supplements alone before the reason for deficiency has been assessed.

Seek prompt medical advice for new or worsening numbness, weakness, trouble walking, marked breathlessness, chest discomfort, or fainting. These symptoms can have several causes, including problems affecting nerves or blood cells, and need an individual assessment. Contact a clinician soon if symptoms are progressing while you are awaiting tests or if you have a condition that may affect nutrient absorption.

Ask what may be causing the deficiency, whether any medicines or digestive conditions could contribute, and which tests will guide treatment. Ask whether tablets or injections suit your situation, when symptoms should improve, and which neurological changes need an earlier review.
