If you lot've got diabetes, keeping blood glucose levels steady is the proper name of the game. Normally, your body regulates blood sugar well, thanks to a series of feedback mechanisms that involve the secretion of the hormone insulin. But in people with type one diabetes, your body doesn't make enough insulin; in type two diabetes, an inability to effectively use insulin causes glucose levels to swing around. "The circuitous regulation of glucose is i reason that managing diabetes can be challenging for patients," says Jacob Kohlenberg, M.D., assistant professor in the division of diabetes, endocrinology, and metabolism at the Academy of Minnesota Medical School in Minneapolis, MN. Here, tips for tracking your blood sugar levels.

Why Checking Your Blood Sugar Is Crucial
Monitoring your blood carbohydrate helps your doctor determine if your treatment plan is working and if your medication needs adjusting. Blood carbohydrate that's also high, referred to as hyperglycemia, or too low, known as hypoglycemia can cause wellness problems such as dizziness, confusion, blurred vision and even blackout. The expert news: "A patient with well-controlled blazon 2 diabetes who's treated with metformin (an oral medication) may only check their glucose a few times a week or month," says Dr. Kohlenberg. (If you have type 1 diabetes and administer multiple insulin injections each day, yous'll need more frequent monitoring.)

How to Rail Blood Sugar Levels
"Blood sugar vacillates throughout the day due to many factors," says Megan Wolf, a registered dietitian and diabetes care and education specialist at Cleveland Clinic in Ohio. The preferred way to keep track of it? Whatever works best for you. "This may include journaling numbers into a logbook or typing claret sugar readings into an app," says Wolf. "A lot of my patients find continuous glucose monitors helpful." Glucometers and continuous glucose monitoring systems store glucose data that can exist uploaded to a computer. Then the patient tin can review their blood carbohydrate data on their device or keep a detailed written log.

How Food Affects Claret Sugar Testing
Testing your blood carbohydrate both right before and afterward meals will give you an idea of how food affects your sugar levels. Ideally, you're looking for numbers of eighty-130mg/dL earlier and less than 180 mg/dL i to two hours after eating. According to Wolf, "Someone should check claret sugar earlier meals when they are on a medication, such as insulin, that requires them to adjust their dose based on their blood carbohydrate reading." This so-chosen correction dose is given if your blood sugar is above your target. It is helpful to check blood sugar one to two hours after eating as well because it tells you how your trunk responded to your repast.

How Meds Touch on Claret Sugar Testing
It'southward important to check blood carbohydrate more than frequently if your doc changes your diabetes medications or if you're prescribed other medications, including steroids and certain antibiotics, which tin can affect blood sugar, notes Wolf. Depending on the drug, it can do wonky things to your blood sugar soon afterward taking information technology, sometimes within a few hours. "For example, glucocorticoids [steroids] such as prednisone can cause hyperglycemia (elevated glucose) via multiple mechanisms," adds Dr. Kohlenberg. His advice: Anytime you start a new medication, review it with your physician to run into if this will impact your glucose and diabetes treatment plan.

Sleep and Blood Saccharide Testing
Testing your blood sugar earlier you go to slumber and afterward you awaken will reveal if information technology is loftier or depression—and what might be causing that. Normally, the torso releases insulin in the early on morning time to go along glucose levels, which naturally ascension in the a.yard., in cheque. If you accept diabetes and your blood sugar is high when you awaken, you may need medication adjustments, says Wolf. On the other hand, if you lot bank check your claret sugar before y'all go to sleep and it's on the lower end, you may desire to eat a snack, adds Wolf. This applies for anyone taking insulin to control their blood saccharide. Your doc volition probable adjust your medication if your blood saccharide is consistently low before bedtime.

Exercise and Claret Sugar Testing
"When we practice, our muscles employ glucose as a source of energy and this increased energy utilisation persists after do," says Celeste Thomas, M.D., assistant professor of medicine in the section of endocrinology, diabetes, and metabolism at the University of Chicago. "This puts some people with diabetes at run a risk for low claret saccharide [hypoglycemia] during and after exercise." For anyone taking insulin, checking your claret sugar both before and after exercising can help yous keep tabs on any sudden driblet. Adjusting your blood saccharide-lowering medication prior to do and eating carbohydrates prior to or during a workout tin can help stabilize those readings, says Wolf.

How a Wintertime Cold Affects Blood Sugar Testing
When you're sick, your body produces actress stress hormones (including cortisol), which can enhance your blood sugar levels, says Betul Hatipoglu, M.D., professor of medicine at Example Western Reserve University School of Medicine in Cleveland, OH. As a effect, "illness, specially infection, can put those with type 1 diabetes at take a chance for a diabetes emergency called diabetic ketoacidosis," adds Dr. Thomas. This is a complication resulting from non enough insulin and needs to be treated immediately with fluids and additional insulin medication. Testing your claret glucose levels regularly tin assist you spot a spike like this and take activity quickly.

Stress and Blood Saccharide Testing
Whether physical or psychological, whatsoever stress has the same upshot. "Stress hormones such as cortisol push the liver to produce more sugars and brand the trunk more than resistant to insulin," says Dr. Hatipoglu. The event: higher blood carbohydrate levels. Of course, everyone gets stressed at times. But it's chronic stress and its issue among people with diabetes—who are non able to process the boosted sugar—that'southward especially problematic. Your all-time strategy: "Monitor blood sugar levels ofttimes and, if needed, adapt the treatment to prevent any complications," he says.

What to Know Well-nigh Blood Sugar Levels and Driving
If yous have type 1 diabetes or have type 2 diabetes and take insulin, information technology'due south possible to develop depression claret saccharide while driving, causing difficulty concentrating, making decisions, and operating the vehicle. You may even pass out. Earlier you lot head out on the road, check your claret sugar levels, especially if you're taking insulin or insulin-releasing med, such as Glucotrol (glipizide), says Dr. Thomas. Depending on the length of your journey, y'all should also pull over during your trip to cheque your levels again. The bottom line: Swings in glucose levels with diabetes can be controlled if you monitor them carefully.
