How Can I Check My Blood Sugar
Use a blood sugar meter or a continuous glucose monitor to check your blood sugar. A blood sugar meter measures the amount of sugar in a small sample of blood, usually from your fingertip. A CGM uses a sensor inserted under the skin to measure your blood sugar every few minutes. If you use a CGM, youll still need to test daily with a blood sugar meter to make sure your CGM readings are accurate.
Diabetes Numbers Warnings And Precautions
If your blood sugar reading is over 400 mg/dL, there is a chance that you have a false reading â particularly if you arent experiencing any symptoms. For example, if there were food particles on your fingers or you used outdated or improperly stored test strips, you might have gotten an inaccurate reading.
If you re-test your levels and your blood sugar is indeed above 400 mg/dL, follow the advice your doctor has given you â whether that includes taking extra insulin or drinking more water â and contact him or her for further treatment advice.
Heres a chart to help you determine if your blood sugar levels are cause for concern:
What Your Blood Sugar Levels Mean
Hyperosmolar Hyperglycemic Nonketotic Syndrome
This mostly affects elderly people. As glucose builds up in your blood, your body tries to get rid of it through your urine.
At first, you pee a lot. Over time, you pee less, but when you do, itâs very dark. This condition can lead to dehydration, coma, and death.
Get medical help right away if you have any of these warning signs:
- Blood sugar level over 600 mg/dL
- Extreme thirst that may later go away
- Warm, dry skin that doesnât sweat
- Fever over 101 F
- Weakness on one side of your body
You can avoid many of these problems by keeping your blood sugar under control. Follow your doctorâs advice about diet and exercise, take your medicine, keep up with your doctor visits, and check your levels often.

How Are Low Blood Sugar Levels Treated
Your diabetes health care team will give you guidelines for treating low blood sugar levels, depending on your symptoms. If you can, try to test your blood sugar levels to make sure that your symptoms are because of hypoglycemia. If you can’t test blood sugar immediately, don’t delay in treating your symptoms you can always check your blood sugar after you’ve taken steps to get your blood sugar back up into the normal range.
When blood sugar levels are low, the goal is to get them back up quickly. To do that, you should take in sugar or sugary foods, which raise the blood sugar level quickly. Your health care team might suggest that you:
- Eat, drink, or take something that contains sugar that can get into the blood quickly. Your doctor may tell you to have really sugary foods or drinks or might give you glucose tablets or gel to take all of these can help to raise your blood sugar level fast, which is what you need to do when it’s low.
- Wait about 10 minutes to let the sugar work.
- Recheck your blood sugar level with a glucose meter to see if blood sugar levels are back to normal.
- Get a glucagon shot , if your symptoms are severe or get worse after you eat, drink, or take glucose.
Sometimes, blood sugar levels can get so low that you may not be awake enough to eat or drink something to get them back up. When this happens, you may need a glucagon shot.
How To Counteract High Blood Sugar
Blood glucose numbers are measured in milligrams per deciliter .
The American Diabetes Association and the American Association of Clinical Endocrinologists have different recommendations for blood glucose targets for most people with type 2 diabetes:
| Timing | ||
| 2 hours after eating a meal | < 180 mg/dL for nonpregnant adults | < 140 mg/dL |
Talk to your doctor to learn more about your blood glucose targets. Your doctor can help you determine which guidelines to target. Or they can work with you to set your own glucose targets.

Only You Can Prevent Blood Sugar Spikes
Its annoying but true: The best way to lower your blood sugar is to avoid a spike in the first place.
Eating whole foods that are low in sugar and exercising regularly will help keep your blood sugar in check. This can be beneficial for people with type 2 diabetes, but medications may also be necessary to keep blood sugar in a healthy range.
To avoid food-based spikes, try to steer clear of added sugars in your diet. The FDA recommends consuming less than 200 calories a day from added sugars.
That sounds pretty simple, but when you realize that 16 ounces of orange juice has 240 calories , its easy to see how sugar consumption gets out of hand.
Its best to avoid all sugary drinks and check the labels. There are hidden sugars in everything from bread to turkey slices, so double-check your favorite foods to make sure you arent getting any unnecessary sweetness.

How Can I Treat Low Blood Sugar
If youve had low blood sugar without feeling or noticing symptoms , you may need to check your blood sugar more often to see if its low and treat it. Driving with low blood sugar can be dangerous, so be sure to check your blood sugar before you get behind the wheel.
Carry supplies for treating low blood sugar with you. If you feel shaky, sweaty, or very hungry or have other symptoms, check your blood sugar. Even if you dont have symptoms but think you may have low blood sugar, check it. If your blood sugar is lower than 70 mg/dL, do one of the following immediately:
- Take four glucose tablets.
- Drink four ounces of fruit juice.
- Drink four ounces of regular soda, not diet soda.
- Eat four pieces of hard candy.
Wait for 15 minutes and then check your blood sugar again. Do one of the above treatments again until your blood sugar is 70 mg/dL or above and eat a snack if your next meal is an hour or more away. If you have problems with low blood sugar, ask your doctor if your treatment plan needs to be changed.

High Blood Sugar Levels
Different targets have been set by various health organizations, but the American Diabetes Association has stated that fasting blood sugar should be between 80-130mg/dL, and two hours after a meal it should be less than 180mg/dL.
Some people experience high blood sugar in the mornings for several common reasons, like the Dawn Phenomenon. Fasting blood sugar is important to note, as it can give an idea of where your blood sugar naturally settles after a period without intervention.
Blood sugar rises after a meal, and then comes back down . Postprandial blood sugar is where it lands at the end of the trend line, which is generally two hours after the meal. If blood sugar is 180 mg/dL two hours after a meal, it could mean mis-calculating carb intake. Knowing the range your doctor has identified as a healthy rise is important in being aware of your bodys processes. Any number above your specific ranges is considered to be high.
Glucose is needed by your body, but when it rises too high over an extended period of time, it can have lasting detrimental effects. Its important that you regularly monitor your blood sugar levels so that youre aware of how your body is responding to your diabetes care plan.
High Blood Sugar: Causes Complications And How To Lower Blood Sugar
Your body breaks down glucose for energy using the insulin produced by the pancreas. This is required for our bodies to function. Illness can have an impact on the way our pancreas functions. Read this to learn how high blood sugar can affect your health.
7 minute read
Your body requires energy to function, and this energy comes from food. Specifically, your body breaks down glucose for energy using the insulin produced by the pancreas.
Type 1 and type 2 diabetes cause impairment to this breakdown of sugar in the body, causing blood glucose levels to become irregular. When glucose is not broken down into energy, it can build up in the bloodstream and then becomes a health problem.
Your pancreas produces insulin, which breaks down glucose. With type 1 diabetes, the cells that produce insulin are mistakenly attacked by your immune system. As a result of this autoimmune condition, blood sugar levels can become dangerously high without intervention.
Type 2 diabetes occurs when your body no longer responds to insulin as well as it should and then also causes glucose to accumulate in the blood.

How Does Hyperglycemia Happen
Insulin is a hormone that lets your body use the sugar in your blood, which comes primarily from carbohydrates in the food that you eat. Hyperglycemia happens when your body has too little insulin to use the sugar in your blood.
People with type 1 diabetes can have episodes of hyperglycemia every day. Although this can be frustrating, it rarely creates a medical emergency. Not taking enough insulin can lead to hyperglycemia .
Other things that can cause hyperglycemia include:
- Having trouble seeing or concentrating
- Experiencing stomach pain, nausea, or vomiting
- Having sweet-smelling or fruity breath
- Cuts or sores that do not heal, infections, and unexplained weight loss may also be signs of long-term hyperglycemia.
If you notice any of these symptoms, you should check your blood sugar. If your blood sugar is very high, you should also test for ketones in either your blood or urine.

What Foods Can Assist Raise Blood Sugar Quickly
Because your blood sugar level comes from the foods and beverages you consume, one of the most convenient methods to raise your blood sugar quick is to grab a quick treat. The American Diabetes Association advises the 15-15 rule if your blood sugar level dips below 70 mg/dL: Eat at most limited 15 grams of carbs, then wait 15 minutes to recheck your blood glucose. If youre still listed below 70 mg/dL, have another 15 grams of carbs, wait 15 minutes, and inspect your levels again.
Amongst the foods you can pursue a fast blood sugar boost are:. a piece of fruit, like a banana, apple, or orange. 2 tablespoons of raisins. 1/2 cup apple, orange, pineapple, or grapefruit juice. 1/2 cup regular soda . 1 cup fat-free milk. 1 tablespoon honey or jelly. 15 Skittles. 4 Starbursts. 1 tablespoon of sugar in water.
Foods that include protein or fat, such as peanut butterand ice cream, and chocolate, may be valuable if your blood sugar level has actually dropped but isnt listed below 70 mg/dL. These higher-fat foods, in addition to whole-grain bread and other high-fiber foods, take longer to take in into your bloodstream. Because of this, these foods will not raise your blood sugar as quickly as foods that have more basic carbohydrates.

Early Symptoms Of Hyperglycemia
Early signs of high blood sugar, or hyperglycemia, may serve as a warning even before you test your blood glucose level. Typical high sugar symptoms may include:
- Increased thirst and/or hunger
- Sugar in your urine
It is important to recognize and treat hyperglycemia because if left untreated, it can lead to additional symptoms and complications, some of which are different for people with type 1 diabetes compared to type 2 diabetes. For example, people with type 1 diabetes are more likely to develop a severe condition resulting from high blood sugar called diabetic ketoacidosis. In addition to the common hyperglycemia symptoms listed above, symptoms of diabetic ketoacidosis include:
- Heavy breathing
Check Your Blood Sugar
If you take medication that may cause low blood sugar , its highly advisable to check your blood sugar levels before you try to bring your sugar levels down.
This is just in case your blood sugar is normal or low, which can be the case in some situations.
Testing of blood sugar before bringing your levels down is particularly important if you take insulin.

Why Do These Symptoms Matter For Diabetics
These symptoms are essential for diabetics to understand, because they may encounter high or low blood sugar levels from time to time.
A cold or virus can cause sudden high blood sugar levels, and understand the symptoms means knowing how to deal with hyperglycemia or hypoglycemia.
People with diabetes who can recognise the symptoms can avoid levels that lead to medical emergencies such as diabetic ketoacidosis
Reflect On The Amount Of Sugar In Your Diet
Hyperglycemia occurs when there is too much glucose in the blood.
Therefore, one way of reducing your blood glucose levels is reflecting on where sugar may be consumed in the diet. Think about any refined and processed foods that may be in your diet as these are often high in sugar. This can be achieved through a low carbohydrate diet.

What Happens To My Blood Sugar Levels When Im Stressed
During stressful situations, epinephrine , glucagon, growth hormone and cortisol play a role in blood sugar levels. Stressful situations include infections, serious illness or significant emotion stress.
When stressed, the body prepares itself by ensuring that enough sugar or energy is readily available. Insulin levels fall, glucagon and epinephrine levels rise and more glucose is released from the liver. At the same time, growth hormone and cortisol levels rise, which causes body tissues to be less sensitive to insulin. As a result, more glucose is available in the blood stream.
When you have type 2 diabetes, low blood sugars from too much medication or insulin are a common cause of stress. The hormonal response to a low blood sugar includes a rapid release of epinephrine and glucagon, followed by a slower release of cortisol and growth hormone. These hormonal responses to the low blood sugar may last for 6-8 hours during that time the blood sugar may be difficult to control. The phenomena of a low blood sugar followed by a high blood sugar is called a rebound or Somogyi reaction.
When you have type 2 diabetes, stress may make your blood sugar go up and become more difficult to control and you may need to take higher doses of your diabetes medications or insulin.
During times of stress, individuals with diabetes, may have more difficulty controlling their blood sugars.
How Do Carbs Affect Blood Sugar
Carbs in food make your blood sugar levels go higher after you eat them than when you eat proteins or fats. You can still eat carbs if you have diabetes. The amount you can have and stay in your target blood sugar range depends on your age, weight, activity level, and other factors. Counting carbs in foods and drinks is an important tool for managing blood sugar levels. Make sure to talk to your health care team about the best carb goals for you.

Easy Ways To Lower Blood Sugar Levels Naturally
High blood sugar, also known as hyperglycemia, is associated with diabetes and prediabetes. Prediabetes is when your blood sugar is high, but not high enough to be classified as diabetes.
Your body usually manages your blood sugar levels by producing insulin, a hormone that allows your cells to use the circulating sugar in your blood. As such, insulin is the most important regulator of blood sugar levels .
However, multiple factors can impair blood sugar management and lead to hyperglycemia.
Internal causes for high blood sugar include when your liver produces too much glucose, your body makes too little insulin, or your body cant effectively use insulin. The latter is known as insulin resistance (
2 ).
The Centers for Disease Control and Prevention reports that 13% of U.S. adults live with diabetes and that another 34.5% have prediabetes. This means that close to 50% of all U.S. adults have diabetes or prediabetes .
Blood sugar management is especially important for people with diabetes, as chronically high blood sugar levels can lead to limb and life threatening complications (
Increased insulin sensitivity means your cells can more effectively use the available sugar in your bloodstream.
Exercise also helps your muscles use blood sugar for energy and muscle contraction .
Whats more, researchers recommend doing so-called exercise snacks to lower blood sugar and prevent the damage that sitting all day can do .
