Can having low or high blood sugar level cause dizziness and falls?

Can having low or high blood sugar level cause dizziness and falls?

Yes.: Low blood sugar (hypoglycemia) or high blood sugar (hyperglycemia) both affect mental status, and can affect balance. You could certainly attribute dizziness or falls to extreme low or high blood sugar. However there are multiple other causes too (heart problems, anemia, etc) so you need to discuss this with your doctor to make sure something important isn't missed. ...Read more

Every morning and afternoon I get really dizzy light headed and have no idea where I am. Is it low blood sugar?

Every morning and afternoon I get really dizzy light headed and have no idea where I am. Is it low blood sugar?

No: In my 35 years of practice, I have never seen a case of reactive hypoglycemia. The disorder doesn't exist, if you're overweight the symptoms are a natural response to your glucose level returning to normal. A glucose tolerance test (if you've had one) is not and never will be a valid diagnostic test for hypoglycemia. Don't waste your money o GTT or any fad diets of treatments. Lose wt if heavy. ...Read more

Red swollen legs: You ask about sudden onset red swollen lower legs. This sound very likely to be cellulitis. Especially urgent to treat if you are a diabetic patient. People who retain water with swollen legs are more prone. Further attacks can be prevented if swollen legs are prevented. Treatment would be with antibiotics. Most frequent germs: streptococcus or staphylococcus. ...Read more

My hb1ac came back slightly elevated and my blood sugar is slightly elevated also. I urinate frequently and get dizzy spells with rashes. Liver probs?

Test results: No, there is no reason to think your liver function is impaired. This does not affect the HGB A1C or the urine.

If your blood sugar is elevated, it can cause you to urinate and feel dizzy. If it is significantly elevated, then a plan may be needed to help- such as exercise, nutrition, and possibly medication. Did your doctor give you a plan including any of these? ...Read more

I always feel dizzy and low during the day when I've eaten. My blood sugar can drop from 130mg/dl to as low as 50mg/dl?

I always feel dizzy and low during the day when I've eaten. My blood sugar can drop from 130mg/dl to as low as 50mg/dl?

Adjust insulin/food: Assuming you have type 1 dm, chronically low blood sugar means that you're over insulinizing for your specific requirements. Discuss with your doctor how to manage that. Make sure you're not just eating carbs. Mixed meals are best. If you're exercising, then go low, you may still need less insulin. Someone needs to go over your total care regimen with you in detail. ...Read more

Haven't walked in years today is ny fourth day waking and at the end of my mile I started to feel real weird dizzy kinda checked my blood sugar 109?

Haven't walked in years today is ny fourth day waking and at the end of my mile I started to feel real weird dizzy kinda checked my blood sugar 109?

Start slower?: Obvious question is WHY haven't you walked in years until today? If you've been wheelchair or bedbound for that long then, to me I think walking a mile at a time is starting a bit too ambitiously. Has your cardiac status been tested? I know you're young but I still believe a stress test may do a body good in this case if you insist on the mile a day. I would be more conservative with distance. ...Read more

I am not diabetic but I always feel low and dizzy when I've eaten. My blood sugar can be 130-40mg/dl and can then drop to 50mg/dl throughout the day?

See your Dr.: Just curious how you happen to be checking your bs. You also need to have your hb1ac checked to see what your average bs is. Your doctor will probably also order a glucose tolerance test. There may be some medications that could possibly help you avoid developing full-blown diabetes which sounds like you could be developing. You need to get checked asap as complications could be developing. ...Read more
