Detailed Answer:
Dear friend,
Welcome to Health Care Magic
You are right.
Fall of pressure (
Postural Hypotension) or sugar (
Hypoglycaemia) could account for his symptoms.
However, other issues should be investigated…
It can be simple anaemia – what is his haemoglobin?
The body's balancing mechanism is in the
inner ear. An ENT (Ear Nose Throat) specialist is the one to see - they have special tests to confirm or exclude the contribution of the ear.
If the ear is excluded, he should be seen by a
neurologist. / MRI may be needed. MRA (MRI
angiography) shows blood vessels and is generally done at the same sitting. The same process affects the blood vessels there too...
If there are no clues, he has to be investigated again by his Cardiologist! HOLTER (24 to 48 hour ambulatory monitoring – for
arrhythmia) /
ECHOcardiogram (for clot) / TMT (Treadmill exercise ECG – for ischemia / preferably with thallium isotope) / LABORATORY work-up – may all be necessary for further assessment and assistance.
CT angio is non-invasive study for the anatomy (structure). If positive, he will need catheterisation, anyway, which though invasive is the gold standard for this. TMT tests the function and is the first choice to evaluate ischemia
The treating doctor may suggest them depending on need, based on his assessment of the situation.
Good luck
Take care
Wishing all well
God bless
