How accurate is a hemoglobin A1c test in indicating hypoglycemia?

How accurate is a hemoglobin A1c test in indicating hypoglycemia?

Poor: Hba1c is fair at detecting chronically high bgs, but very poor at detecting low bgs. Fortunately, true low bgs are very rare and almost never sustained or recurrent. The sensation of "hypoglycemia", when related to sugar at all in people not treated with diabetes medications, is usually the normal response to low-ish sugars, which corrects them and keeps the body well. ...Read more

My A1c is 5.9 & cortisol after 8 am test 33.5, insulin 28.7. I always feel shaky after meals . Dr says I have reactive hypoglycemia are my test bad?

My A1c is 5.9 & cortisol after   8 am test 33.5, insulin 28.7. I always feel shaky after meals . Dr says I have reactive hypoglycemia are my test bad?

Needs evaluation: The hba1c is mildly high and could indicate pre-diabetes. You need a fasting glucose and lipid profile to see more. The cortisol level appears high, you need to do an overnight Dexamethasone suppression test to evaluate. Most people who feel shaky after meals do not have low sugars causing it. You should check your sugar with a glucose monitor when you have symptoms. ...Read more

How precise is hemoglobin A1c with indicating hypoglycemia?

How precise is hemoglobin A1c with indicating hypoglycemia?

Not good at all: Hgb a1c should not be used to assess for hypoglycemic episodes or trends. It indicates only average blood sugars over months, and if there is concern or symptoms of hypoglycemia, then fingerstick blood sugar levels should be checked. Do some random ones, especially at night, and after high demand glucose things like exercise. Also check if having any symptoms - don't drive if you are low! ...Read more

More I read about hypoglycemia more confused I get. If I miss bkf AND lunch I feel weak + hands shake, no other sx. A1c and 12h fasting gluc normal.

Most of it is bunk: Miss a few meals and your body will produce epinephrine to keep your blood sugar normal. That's why you shake. Please forgive me -- if you're so worried about "hypoglycemia", please adopt more sensible eating habits. Think about getting back into heavy-duty fitness. Almost everythingyou read about "hypoglycemia" apart from diabetes is rubbish. Best wishes. ...Read more

Fasting glucose 36mg/dl w/ fainting spells, after meal 82mg/dl, A1c 5.5 (math err?). Can a 8mm adrenal cyst cause hypoglycemia? Also-abd pain, acnes.

Fasting glucose 36mg/dl w/ fainting spells, after meal 82mg/dl, A1c 5.5 (math err?). Can a 8mm adrenal cyst cause hypoglycemia? Also-abd pain, acnes.

You don't: Have hypoglycemia after meals, as it's not a disease and doesn't exist in the absense of diabetes medication, cancer, end-stage liver or kidney disease, GI surgery, etc. If it's a finger-stick it's not accurate in that range. Your adrenal cyst is benign and has nothing to do with your complaints. Cyst should be followed over time. Glucose should be ignored ; it's a natural response to your obesity. ...Read more

Could taking thiazide affect your A1c test results?

In a way, yes: Diazide worsens control of diabetes and may raise blood sugar level and indirectly raise a1c levels. The drug diazide does not directly affect the assay for a1c. See this site for more information on side effects of diazide. http://hyper.ahajournals.org/content/54/2/196.full. ...Read more

My hb A1c test result shows 7. What exactly it means?

My hb A1c test result shows 7. What exactly it means?

Hb A1c test: A1c measures % of hemoglobin in blood which has glucose (blood sugar) attached to it. Normal for someone without diabetes should be around 4% or less. 7% is considered good control with diabetes. Too high (8% or above) increases risk of complications. If test was done for screening (not already on treatment for diabetes), your diabetes may be controllable with strict lifestyle changes. Good luck! ...Read more

Had my A1C checkefd about a year ago it was 7.2. I just did a home test and it is now 6.1 is that better?

Depends: An Aic level of 7.2 means that you are diabetic. Have you been on treatment for diabetes? If you were extremely compliant with the treatment, it is possible that your A1c level is 6.1 and that would be good. However, home tests are not as accurate as lab tests. If you have not been under treatment, you should consult your doctor at the earliest. ...Read more

Should I discontinue dmt2 med since my A1c is 6.5 and return in 3 months to test it again as experiment? Just die & exercise. I'm tired of taking med.

Not recommended: Don't stop any meds without talking to your doctor first. I know you are on metformin and onglyza (saxagliptin). At this point, i recommend continuing metformin but if you want to stop something, stop the Onglyza (saxagliptin) instead. Please see your doctor to discuss this before doing anything. Good luck. ...Read more
