It's always interesting when people come in complaining about something that they don't think is in my scope of work, as though basic analysis isn't important before any work is done.
Doesn't mean anyone is always right (even wives!)
Dizzyness is often mentioned in passing.
Here's a few things considered when this happens:
What are the causes of dizzyness?
At first glance it’s a brain dysfunction so problems with the function and / or structure of the brain can cause it.
What can cause those?
Rupture of artery or vein in the brain can cause sudden onset dizzyness.
Raised intracranial pressure, distorting the brain structure as a result of failure of drainage can do the same, if slightly slower acting until it reaches a threshold level where total blockage suddenly applies.
Dropping blood pressure can do the same.
How else to affect brain function?
Toxicity, insufficient oxygen, insufficient carbon dioxide, insufficient glucose.
Insufficient oxygen could be a failure of the heart to output enough blood, obstruction of the arteries that supply the brain, failure of the lungs to transfer oxygen to the blood.
Insufficient carbon dioxide usually comes from overbreathing and blowing off too much CO2. A certain level of CO2 is needed to stimulate the arteries of the heart and central nervous system to open wide. Slight narrowing of those vessels dramatically reduces blood flow.
Insufficient glucose can come from disorders of digestion, hormonal problems (diabetes), problems with the liver.
Toxicity can be from localised infection, kidney and liver failure, sepsis and generalised tissue breakdown like seen with crush injuries and medication or other drugs.
Brain processing can be affected by all the above as well as emotions, history and habits as the brain struggles to come to terms with sensory inputs.
The eyes, middle ears and the nerves associated with them can contribute to dizzyness as well as the proprioceptive nerves that inform the brain of where the parts of the body are and what they are doing. :)
