What If Your Glucose Levels Are Abnormal

When to Check Your Blood Sugar

Health conditions such as diabetes and hypoglycemia will obviously have a big impact on your blood sugar levels. Pregnancy can also affect your blood sugar, which sometimes results in gestational diabetes for the duration of the pregnancy.

The American Diabetes Association points out that every persons recommended blood sugar level is different and is based on several health factors. But, in general, the target range for glucose levels in diabetes is 80 to 130 milligrams/deciliter before eating and less than 180 mg/dl after a meal.

If your glucose levels dont fall within the normal range, you and your doctor will need to make a plan to determine the reason why. Additional testing for diabetes, hypoglycemia, certain medical conditions, and other endocrine issues may be necessary to identify why your blood sugar is too high or too low.

Continue to monitor your blood glucose levels while you wait on test appointments or test results. If you experience any of the following symptoms, let your doctor know right away:

If Your Diabetes Medication Changes

When your medication for diabetes changes or is adjusted, its important to know how that change is working. The best way is to check your blood sugar levels more often, according to FamilyDoctor.org. Check your blood sugar levels before and after taking medication and keep track of the results to show your doctor.

/8the Right Time To Check Your Blood Sugar Levels

The perfect time to check the fasting glucose levels is right after your wakeup. And the right time to check postprandial glucose levels is two hours after you have your meals.

A gap of two hours after a meal must be maintained to get the correct reading.

This helps you choose the right foods and medication. When you test before your meal, it tells you how much medication you need and when you test two hours after eating, you know if your medicines are working fine for you.

Blood Sugar And Heart Disease

7 Blood Sugar Testing Mistakes to Avoid

As was just briefly mentioned, poor blood sugar regulation ultimately contributes to heart disease. This is because chronically elevated insulin drives up inflammation and contributes to the oxidation of cholesterol within the arteries. Chronic elevation in insulin also increases blood pressure and LDL cholesterol, creating the perfect storm for heart disease development.

This is likely the reason why it is so common for those who have heart issues to also have diabetes and general metabolic disorders. Whenever I am working with someone who is concerned about heart disease, the first thing I recommend is to test blood sugar on a regular basis and use strategies to ensure it remains stable.

What To Expect From Your Blood Sugar In The Morning

After an overnight fast, a normal blood sugar level is less than 100 milligrams per deciliter , according to the American Diabetes Association . But, according to Susan Spratt, MD, an endocrinologist and associate professor of medicine at Duke University School of Medicine, not everyone with type 1 or type 2 diabetes has to shoot for “normal” levels.

“If you’re young, the goal may be to get your fasting blood sugar levels to less than 120 mg/dL,” Dr. Spratt says. But if you’re older and have other health conditions, that number may be higher, she says.


The ADA points out that not everyone will have the same blood sugar level goals. Instead, your endocrinologist or doctor will calculate your target number based on your age, how long you’ve had diabetes, whether you have health conditions like heart disease and other factors.

Keep in mind, too, that your fasting blood sugar levels can be too low. For example, a morning blood sugar reading below 70 mg/dL can indicate a hypoglycemia, or low blood sugar.

Blood glucose goals should be higher than those listed in the table for children who have frequent cases of hypoglycemia and don’t experience the associated signs and symptoms.


Your child’s diabetes health care team will recommend an individualized target range for blood sugar levels. The general goal is to maintain as normal as possible blood sugar levels without causing frequent low blood sugar. Research has shown that in children under the age of 6, frequent, severe low blood sugar levels may result in neuro-cognitive deficits problems related to intellectual ability so target ranges are higher in this age group.

Adolescents should strive to achieve similar target ranges as adults. However, this may be difficult because of higher hormone levels, such as growth hormones, which counteract the effects of insulin. If your child’s sugar levels are in the ranges listed below at least 50 percent of the time, then blood sugar control is considered reasonable. If sugars levels exceed the range more than 50 percent of the time, then sugar control is not optimal and the diabetes plan should be changed.
