Why do I keep feeling dizzy?
Not a diagnosis: a head start. These are the three drivers most worth checking first, based on what the evidence says gets missed most often.
Spinning vs fading
True spinning (vertigo) is inner ear or neurological; fading/greying is blood pressure or blood flow. Different paths.
Standing drops
Lightheaded on standing suggests orthostatic blood pressure issues. Easily tested at home.
Iron and B12 again
Anaemia steals oxygen from the brain; dizziness is an early note.
Lying/standing blood pressure, full blood count, B12
1. Start a two-minute note so the pattern becomes visible.
2. Take the test list above with you so you can explain the pattern clearly.
3. Read the evidence: Blood Pressure: The Things Your Doctor Doesn't Have Time to Explain.
