My husband, age 82, Type 2 diabetes, has experienced dizzy spells that last for about 10-15 seconds & says head area heats up. Seems to be worse when bending over & then stand up. Recently blacked out, fell & hurt his head, but seemed to recover within a few minutes. He has had 2 TIA s in the last 2 years. Taking Metformin & Glipizide. Hasn t had high blood pressue. What types of issues cause these symptoms? My email is: YYYY@YYYY Thank you for your response. Our local DR hasn t responded as of yet to our inquiry.
