Dear-thanks for using our service, dizziness could be secondary to multiples reasons for which you need a basic physical and laboratory examination to determine the causes. The most common are; hypoglycemia (specially if you don't eat regularly and starve for long hours), hypotension (including orthostatic hypotension which happens when you stand up fast), positional vertigo (mostly when moves the head fast) and carotid insufficiency (secondary to carotid artery stenosis). However, I will advise you to have the evaluation and will be able to have more tools for the correct diagnosis. I hope that my advice has been helpful Chat Doctor.
