Blood Sugar (Definition)

The blood sugar concentration or blood glucose level is the amount of glucose (sugar) present in the blood of a human or animal. The body naturally tightly regulates blood glucose levels as a part of metabolic homeostasis. Glucose is the primary source of energy for the body's cells, and blood lipids (in the form of fats and oils) are primarily ...Read more

Would a blood glucose monitor with a low battery, but still working, give a false reading?

Would a blood glucose monitor with a low battery, but still working, give a false reading?

It Might: Like any other electronic device a good battery supply is essential if we want to get accurate readings. Your numbers may be coming out accurate but change the battery to make sure. If you have already done that then your number should be accurate. I wouldn't place a whole lot of stock in blood sugars before you changed the battery as they may have been off. Start for now and you will be confident. ...Read more

What is a blood glucose monitor?

What is a blood glucose monitor?

Checks blood sugar: A blood glucose monitor is used to check the concentration of blood sugar (glucose). This is helpful for people with diabetes, a disease in which high blood glucose causes damage to the body over time or, if the glucose is severely high or has risen very quickly, can be fatal rapidly if left untreated. A normal blood glucose before eating is under 100, diabetic is over 125. ...Read more

Is there a blood glucose monitor that does not require a prick to get results?

Is there a blood glucose monitor that does not require a prick to get results?

Sorry, no: At this time, real time blood sugar monitoring requires capillary blood, which involves a needle prick. Some meters allow for use on palms an thighs, but the result is less accurate. Continuous glucose monitors can check bgs every 5 min to let your dr see 'the overall trend' over several days, but even then you still have to check finger stick 2-4 times daily to calibrate the monitor... ...Read more

Without diabetes you don't have to do home checks, but follow up with your doctor. ...Read more

What method is used for monitoring blood glucose levels in diabetic patients?

3 means: Hi. There are fundamentally 3 means to assess blood sugar. Finger stick blood glucose is the old standard, around since about 1980. A1c reflects a roughly 3-month average blood glucose. Lastly, continuous glucose monitoring (CGM) is an amazing new tool I use tons in my practice; patients (myself included) LOVE it! All 3 have their places in diabetes management. Good luck! ...Read more

I am up urinating every hour and can't sleep. My hubby got me a blood glucose test monitor and it was 98. Is this high? Normal?

I am up urinating every hour and can't sleep. My hubby got me a blood glucose test monitor and it was 98. Is this high? Normal?

Nope: No, that's a normal number, especially if you hadn't been fasting beforehand. For fasting glucose levels, we consider normal to bee under 100. For non fasting, under 220. Maybe it'd be a good idea to go have your urine tested by your doctor. Urinary frequency can also be a sign of infection. ...Read more

Is safe to have blood glucose & still feels fine? Is that a good sign of diabetes or false readings the meter gives? I've taken medicine everyday & exercise. I don't know it's the meds that work or false readings.

Is safe to have blood glucose & still feels fine? Is that a good sign of diabetes or false readings the meter gives? I've taken medicine everyday & exercise. I don't know it's the meds that work or false readings.

No symptoms: Unfortunately, the complications of diabetes are insidious. Most don't know they have complications until the doctor starts looking or when things are very far along. Good blood sugar control and mgmnt of other co-occurring illness like high bp, dyslipidemia, obesity, and maybe sleep apnea will help also. Your meter can be checked thru your doctor's office. Meds may need to be adjusted, too. ...Read more
