What is the most useful thing I can tell the doctor?
Whether the room spins, or whether you feel like you might faint. Those two answers lead down entirely different paths — spinning points at the inner ear, faintness points at blood pressure, blood or the heart. Almost everything else follows from that one distinction, and it is why "dizzy" on its own is such an unhelpful word.
Could it be my tablets?
Very possibly — in older adults, medication is the commonest cause. Blood pressure tablets, alpha blockers like tamsulosin, diuretics, antidepressants and codeine are frequent culprits, and several together are worse than any one. A proper medication review is the single most effective step, and the one most often skipped. Bring a written list.
How do I know if it is my heart?
Three features. Fainting or dizziness during exercise. Fainting with no warning whatsoever. Palpitations or chest pain alongside. Any of those needs urgent assessment with an ECG — they are not situations for reassurance. A family history of sudden death under 40 raises the same concern.
Why am I worse in the dark?
Because balance relies on three inputs — inner ear, sensation from the feet, and vision. If one is impaired, vision compensates — and in the dark that compensation disappears. Being noticeably worse in the dark or on uneven ground points towards the nerves in the feet or the balance organs rather than towards fainting.
I've been dizzy for months and told nothing is wrong.
It may be persistent postural-perceptual dizziness — a constant low-level unsteadiness that often follows an initial vertigo episode, worse in busy visual environments like supermarkets. It is a real, recognised condition, not anxiety, and it responds to vestibular rehabilitation rather than to more scans. Being told nothing is wrong is a common and demoralising experience here.
What can I do about dizziness on standing?
Two things. Stand up in stages — sit on the edge of the bed for a minute first. And before you rise, pump your ankles and clench your calves and buttocks for 30 seconds, which measurably raises your blood pressure beforehand. Also check whether a lying-and-standing reading confirms it, and get your medications reviewed.
Should I keep taking my dizziness tablets?
Probably not, if you have been on them for weeks. Prochlorperazine and similar drugs are for short-term use in acute vertigo only. Taken longer, they stop the brain compensating, prolong the dizziness, and cause drowsiness and movement side effects. Long-term use is one of the commonest prescribing problems in this area and is worth reviewing.
Can I still drive?
Not if dizziness or fainting could happen without warning. Depending on the cause — and particularly after unexplained loss of consciousness — there may be a legal duty to notify the DVLA. It is worth asking directly rather than assuming, and we will tell you where it applies.
