I went to the GP and she said she thought it was vertigo but I must have an infection for my bp and bg to be so high. I had thought maybe my bp was low but it was extremely high also. She took blood tests which showed nothing but low potassium and gave me an antibiotic. I am better but she still didn't tell me what was causing it. Still a little dizzy.
"My blood sugar was almost 300 would that cause this?"
If your morning fasting levels are this high you need to first see what your bedtime levels are. There are several causes for high morning blood sugars, the most predominate is late night or just before bedtime eating. Another is insulin resistance. Go see your doctor, levels this high may warrant the addition of insulin.
BG of 300 is way too high need to see an MD that kind of BG is dangerous.
lots of things can raise BG infection, diabetes, some meds (you dont say what your med is) also BP meds can make you dizzy.
you need to see an MD not a forum on the internet where you can get advice from me
