What does dizziness feel like with vitamin B12 deficiency?

The sensation may occur with tiredness, reduced exercise tolerance, pale skin, a sore tongue, or breathlessness linked with anaemia. Numbness, tingling, a burning feeling in the feet, clumsiness, or difficulty judging where your feet are can point to nerve involvement. These symptoms can develop gradually, and dizziness may also come from dehydration, low blood pressure, inner-ear problems, medication, or other conditions. A blood test and clinical history are needed to identify the cause.

Arrange an appointment if dizziness persists, returns, or appears with tingling, balance changes, or unusual fatigue. A clinician may assess blood counts, vitamin levels, diet, absorption problems, and medicines. Avoid starting high-dose supplements as a substitute for assessment, because treatment depends on why the level is low. Rise carefully, use support when unsteady, and avoid driving if your balance or concentration is impaired.

Get urgent help for sudden weakness or numbness on one side, trouble speaking, fainting, severe breathlessness, chest pain, confusion, or inability to walk safely. Seek prompt medical advice for worsening numbness, repeated falls, or new bladder or bowel control problems.

Ask which tests could clarify whether vitamin B12 deficiency is involved, whether nerve symptoms need prompt treatment, and what may be affecting absorption or intake. Mention dietary restrictions, stomach or bowel conditions, previous surgery, and all medicines and supplements.
