Is episodes of light headiness of increasing intensity and frequency any serious indication ?
Patient: periods of light headiness of gradually increasing intensity and frequency over 2 months growing from 1-2 seconds to1-2 min without loss of conciousnes but progressing deminsished conciousness,Strong normal cardio pulmonary health.No unusual activity or intake.Is it a serious indication? Doctor: Hi,  There are a few possibilities. One would be hypoglycemia due to improper release of insulin and/or suboptimal eating habits (which could also include dehydration).    Another could be headache aura perhaps most likely related to migrainous vertigo where the spells you refer could be part of the vertigo portion of the disorder.    A 3rd possibility is that of orthostatic hypotension that may be occurring inappropriately or in response to overactivity/oversensitivity to medications used to control blood pressure, etc.   The only way to know for sure would be to have a thorough examination by your primary doctor followed up by a specialist as indicated if the primary is unable to figure out the problem.  Hope I have answered your query. Let me know if I can assist you further.  Regards, Dr. Dariush Saghafi, Neurologist
