Would an ordinary blood test catch low blood sugar/hypoglycemia?

Would an ordinary blood test catch low blood sugar/hypoglycemia?

Only if it is tested: Your doctor has to request the test for blood sugar and indicate if it is fasting or random blood sugar level. Most testing doe snot include blood sugar unless the doctor orders a complete metabolic panel of tests. ...Read more

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

Help please. Could an ordinary "blood test" catch low blood sugar/hypoglycemia?

Help please. Could an ordinary "blood test" catch low blood sugar/hypoglycemia?

Yes: If the sample is obtained when the blood sugar is low and collected and run appropriately (in a hospital lab) it can be diagnostic for hypoglycemia. Tests can also be done for causes. Other ways to look for low sugars include continuous glucose monitoring systems and hemoglobin a1c that evaluates average blood sugar over time. Glucose meters are not usually useful in diagnosing hypoglycemia. ...Read more

I'm not sure but is hypoglycemia/low blood sugar hereditary?

I'm not sure but is hypoglycemia/low blood sugar hereditary?

Are you on insulin?: Hi. Unless you take insulin or have a vanishingly rare genetic syndrome, your "hypoglycemia" is not real, and has nothing to do with blood sugar. Unfortunately, "hypoglycemia" is a very popular self diagnosis, but it is not true hypoglycemia and has nothing to do with your blood sugar. Diabetes can be hereditary, and if treated with insulin, that would be true hypoglycemia. ...Read more

I took a blood sugar test due to having symptoms related to hypoglycemia for several months. It was 69mg/dL, is this low? What should I do now?

I took a blood sugar test due to having symptoms related to hypoglycemia for several months. It was 69mg/dL, is this low? What should I do now?

Not low blood sugar: Nope. That's stone-cold normal. Are you diabetic or obese? Unless you're on Insulin (or a few other drugs) for diabetes, hypoglycemia is very, very rare, and usually due to an insulin-producing tumor in the pancreas. "Hypoglycemia" used to be a common fad diagnosis, but it isn't a real diagnosis in those cases, and those people's symptoms have nothing to do with blood sugar levels. Look elsewhere! ...Read more

Do abnormally low blood sugar levels mean I have hypoglycemia?

Do abnormally low blood sugar levels mean I have hypoglycemia?

Yes.: Hypoglycemia is abnormally low blood sugar levels. Though laboratories have different cut-offs, usually a blood sugar less than 70 mg/dl is considered low. Normally, the body regulates blood sugar to prevent extremely high or low blood sugar. There are some serious and some not so serious causes for hypoglycemia, and a thorough evaluation with appropriate testing is in order. ...Read more

Is the "phenomenon of craving" that alcoholics describe be simply hypoglycemia (low blood sugar)?

Appetite: Alcohol affects the liver and is a toxin to the liver. The liver regulates blood sugar through the products it makes. Also low blood sugar or blood sugars that are dropping rapidly drive appetite. So it is possible the alcohol is contributing to metabolic stresses. Best to get help with any addiction. ...Read more

I have hypoglycemia and I can be 55-65 with no symptoms and sometimes feel better with low blood sugar. What can cause this?

At risk for diabetes: Whenever hypoglycemia occurs, it implies that there's a problem w/ how much insulin ur body makes (in this case too much @ the wrong time). Oddly enough, this means in the future your pancreas may "run out" of insulin when it needs it: diabetes. Consider this "pre-diabetes" or a diabetes risk factor.

I have been diagnosed with reactive hypoglycemia, but often feel symptoms of low blood sugar even though glucose tests show my sugar to be just right.?

4 reactive hypoglyce: Eat only meat or fish or cheese or eggs or poultry and low starch veggies, drink only water. In other words avoid all carbs, carbs will only briefly raise your sugar levels and then your Insulin levels. The fats in the meat or fish or cheese or eggs or poultry will act like a "log on your metabolic fire" to keep your blood sugar stable for hours without raising insulin. ...Read more

Non Diabetic: "Reactive" hypoglycemia is REAL (Some feel it may be a form of PRE-DIABETES but is seen in OBESITY and in some very unusual cases due to a tumor of the pancreas (called an insulinoma) IN SHORT, this needs interpretation by a Board Certified ENDOCRINOLOGIST or DIABETOLOGIST!

Can blood sugar drop way down into 40s and still be just reactive hypoglycemia or hypoglycemia. Or being that low, more likely insulinoma?

Can blood sugar drop way down into 40s and still be just reactive hypoglycemia or hypoglycemia. Or being that low, more likely insulinoma?

It will require comp: Complete testing by an endocrinologist is essential in order to sort this out. Yes I do think that reactive hypoglycemia can cause sugars to go down near 50-60mg. Most insulinomas produce more severe lowering of blood sugar, generally in 30-40 mg range. Yet we can not be certain wiuthout checking your pancreas with ct scans. ...Read more

Why do diabetics have problems with low blood glucose or hypoglycemia?

Over treatment: The most common cause of low blood sugar in a diabetic is overtreatment with diabetes medications (either you give Insulin and didn't eat or eat enough, or you started doing more activity beyond what you usually do). If this is a consistent problem, make sure you talk to your doctor to get your treatment regimen reevaluated. ...Read more

Can antihistamines make my hypoglycemia worse? Seems like i'm having more low blood sugar occurrences while on Claritin (loratadine) or allegra.

Allegra (fexofenadine): I don't think so. If you really observe hypoglycemia when taking antihistamine then make you sure you eat 3 times a day, eat fruits between meal and just before your meal. Symptomatic hypoglycemia usually occur when blood sugar <80. We like to keep it above than 100. Symptom could include irritability, dizziness, sweating, weakness, confusion, passing out or death. ...Read more

How to keep a normal blood sugar during the day and night for hypoglycemia?

Frequent small meals: Usually suffice for maintaining bs during the day. At night, it's good to have a starchy or complex 20-25 gram carb before bedtime. I do suggest that you or your friend seek a medical evaluation to see if there is an endocrine case such as adrenal insufficiency or insulinoma (rare). If family history is positive for hypoglycemia then it's poosible that it may be due to a potassium channel defect. ...Read more

Healthy food, less r: Eat healthy food. If you're on diabetes medication, then you need less. Talk with your doctor. If you don't have diabetes and aren't taking medication to lower your glucose, then you don't have hypoglycemia. You just have a natural lowering of high glucose to normal, which causes your symptoms. Weight loss and a better diet will stop the symptoms. Don't worry, symptoms won't hurt you. ...Read more

What does it mean if you have the symptoms of hypoglycemia, yet your blood sugar is within normal limits?

It means you don't: Have hypoglycemia. The symptoms of "hypoglycemia" are not due to low sugar, but a drop in sugar from a higher level back to normal. This is what the body is supposed to do. This occurs in people who are overweight and Insulin resistant. Start eating less, and exercising more to lose weight and lower your chances of developing diabetes in the near future. ...Read more

Yes, there's a test: Hi. But it's very, VERY unlikely you're hypoglycemic. Like next to zero, unless you take insulin, or rarely, have it as a side effect of bariatric surgery. "Hypoglycemia" is a very popular self-diagnosis with no validity. Hunger does not equal hypoglycemia. The test for hypoglycemia is a hospital admission for a 72 hour fast (ad lib water). ...Read more

Why would i get hypoglycemia symptoms when my blood sugar is 5.4? I eat a balanced diet too this is ruining my life

No: In my 35 years of practice, I have never seen a case of reactive hypoglycemia in the absence of diabetes or GI surgery. The disorder doesn't exist, if you're overweight the symptoms are a natural response to your glucose level returning to normal. If you have diabetes, you need to reduce your medication, particularly Insulin if you're having true hypoglycemia. ...Read more

I have diagnosed hypoglycemia.  My blood sugar drops when I take allegra (fexofenadine). Why would this be?

Cause Hypoglycemia?: How low does your blood sugar get after taking this med? Some people with hypoglycemia may actually be Insulin resistant or frankly have type 2 diabetes. The stimulant part of this drug can further exacerbate pre-existing Insulin resistance and therefore also higher Insulin levels which could lead to more hypoglycemia. Please discuss with your doctor. ...Read more
