If you find that youre eating less due to an illness or other factors, your medications may need adjusting, so its important to talk to your doctor. Meanwhile, here are some general guidelines:

  • Mealtime insulin: For mealtime insulin, if you skip the meal, you should also forego the mealtime insulin.
  • Long-acting insulin: The dosage for long-acting insulin is not usually based on food intake, so your doctor will not likely recommend a dose reduction.
  • Other medications: There are some diabetes medications that will lower your blood sugar when high, but wont normally cause hypoglycemia. They may or may not need adjustment, depending on how much youre eating. These medications include metformin, SGLT-2 inhibitors and DPP4 inhibitors.

Why Do I Need To Know My Blood Sugar Numbers

Your blood sugar numbers show how well your diabetes is managed. And managing your diabetes means that you have less chance of having serious health problems, such as kidney disease and vision loss.

As you check your blood sugar, you can see what makes your numbers go up and down. For example, you may see that when you are stressed or eat certain foods, your numbers go up. And, you may see that when you take your medicine and are active, your numbers go down. This information lets you know what is working for you and what needs to change.

High Blood Sugar Level Causes

Several types of diabetes and medical conditions are the primary cause of high blood sugar levels. Most of which are unpreventable issues but are the reason for a spike in high blood sugar. The causes for high blood sugar levels are as follows:

Causes of low blood sugar levels are very different and are as important to be aware of, as they are in fact easier to control.

Total Daily Insulin Requirement:

= 500 ÷ TDI = 1unit insulin/ 12 g CHO

This example above assumes that you have a constant response to insulin throughout the day. In reality, individual insulin sensitivity varies. Someone who is resistant in the morning, but sensitive at mid-day, will need to adjust the insulin-to-carbohydrate ratio at different meal times. In such a case, the background insulin dose would still be approximately 20 units however, the breakfast insulin-to-carbohydrate ratio might be breakfast 1:8 grams, lunch 1:15 grams and dinner 1:12 grams.

The insulin to carbohydrate ratio may vary during the day.

Why Are Blood Sugar Levels Important

One Drop

Measuring blood sugar levels and understanding what your glucose levels should be is an essential part of diabetes treatment for many people with diabetes.

Blood sugar level refers to the total amount of glucose circulating in the blood. In different parts of the world, different units for measuring blood glucose are standard.

What Should I Do If My Blood Sugar Gets Too High

High blood sugar is also called hyperglycemia . It means that your blood sugar level is higher than your target level or over 180. Having high blood sugar levels over time can lead to long-term, serious health problems.

If you feel very tired, thirsty, have blurry vision, or need to pee more often, your blood sugar may be high.

Check your blood sugar and see if it is above your target level or over 180. If it is too high, one way to lower it is to drink a large glass of water and exercise by taking a brisk walk. Call your health care team if your blood sugar is high more than 3 times in 2 weeks and you dont know why.

Ways To Test Your Blood Sugar

Traditional home glucose monitoring

You prick your finger with a small, sharp needle called a lancet, put a drop of blood on a test strip, and then place the strip into a meter that displays your blood sugar levels. Record the test results so you can share them with your doctor. Based on your results, the two of you may adjust your diet, exercise, or medication.

Meters vary in features, portability, speed, size, cost, and readability . Devices deliver results in less than 15 seconds and store this information for future use.

Some meters also calculate an average blood sugar level over a span of time. Some also feature software kits that take information from the meter and display graphs and charts of your past test results. Blood sugar meters and strips are available at your local pharmacy.

Meters that test other parts of your body

Some devices let you test your upper arm, forearm, base of the thumb, and thigh.

These results may differ from the blood sugar levels gotten from a fingertip stick. Levels in the fingertips show changes more quickly. This is especially true when your sugar is changing fast, like after a meal or after exercise.

If you have symptoms of low blood sugar, donât rely on test results from other parts of your body.

Continuous glucose monitoring system

You’ll still need to check your levels throughout the day continuous glucose monitoring doesn’t replace that. It gives your doctor more information about trends that self-checking might not show.

For those with high blood sugar levels, it is vital to keep track of your blood sugars at home on a daily basis. This can be done with a glucose meter. These test monitors are often provided to diabetic patients so that they can manage their blood sugar levels at home everyday. They are available to purchase online if you are non-diabetic but wish to check on your levels regularly for safety.

Diabetic patients can be prescribed medications to help with insulin levels when their blood sugar is high. Those with type 1 diabetes will be prescribed medication which needs to be taken several times daily. This type of diabetes has no cure but can be managed with the right medication.

Those with type 2 diabetes or gestational diabetes can treat their high blood sugar with a change in diet or exercise. A healthier balanced diet is usually advised and sometimes, insulin medication is also prescribed if the blood sugar level becomes abnormally higher than the high reading for diabetic patients.

Symptoms Of Blood Blood Sugar Levels

Symptoms of blood sugar levels differ depending on if it is high or low. To determine which way the blood sugar have moved, the symptoms for each are typically:

If symptoms are left untreated, more extreme circumstances can happen such as fainting, weakness, disorientation, vomiting and dehydration. When you notice symptoms, usually more than one at one time, it is advised to see a doctor right away.

It is important to get the right treatment so that you can return to a healthy normal blood sugar level and inhibit it from occurring again.

Treatment methods vary from the severity of the blood sugar level, whether it is high or low and if the patient has existing medical conditions, such as diabetes. Here are ways in which blood sugar levels can be treated:

Average From A Glucose Meter

Although an A1C level gives you a sense of average glucose levels over the past few months, a person with type 1 or type 2 diabetes needs a blood glucose meter to check blood sugar and make treatment decisions on a day-to-day basis.

If you test often during the day like before and after meals and other times that your blood sugar can vary and use an accurate glucose meter, this can give you valuable information on daily variations in blood sugar levels. Many blood glucose meters are also equipped to provide 7, 14, 30, or 90-day averages. A 90-day average on your meter can be used in the calculator above to estimate how it may correlate to an A1C.

Glucose meter averages are based on the frequency that you have tested per day, so if you do not have many data points or are unable to test at certain times , it probably wont give you a full picture of your blood sugar levels and may skew lower than an A1C test result.

How To Check Blood Sugar Without A Meter

Diabetes is a chronic condition where the body either doesnt make enough insulin or doesnt use insulin properly or both. This can lead to a higher than normal blood sugar level.

Uncontrolled blood sugar levels can lead to complications, such as:

  • heart disease
  • nerve damage

For these reasons, its important to monitor your blood sugar if you have diabetes.

Prior to using meters, people with diabetes would monitor their blood sugar by testing their urine. This method, however, wasnt as accurate, nor did it provide real-time results.

If you self-test your blood sugar several times a day using a glucometer, or meter, it requires that you prick your finger to draw blood to test. Due to the discomfort of this method, you might look for a way to monitor your level without this tool.

If finger pricks are very bothersome for you, dont worry theres hope. Advances in blood sugar monitoring technology could mean no more finger pricks in the future.

If you have diabetes, there are several portable devices you can use to check your blood sugar level and not all of them require a finger prick.

Blood glucose is the amount of sugar in your blood. The normal range for blood glucose on a fast is 80 to 110 milligrams per deciliter. As a diabetic, I fudge a little on that range…I might fall below 80 or run up a little higher. But the goal is to keep the blood glucose in a fairly tight range. One important lesson for the diabetic is how to calculate an insulin correction factor. The insulin correction factor is a bolus of insulin to bring down a higher than range blood sugar level. In order to know this factor, you need to know how much one unit of rapid-acting insulin will drop the blood sugar! Time to play with math!

How To Stabilize Your Blood Sugar Overnight

The most important thing you can do to stabilize your blood sugar is monitor your glucose levels at bedtime, during the night, and when you wake up to look for patterns. This will help you determine whats going on in your body and how you can fix it. While there are many strategies people use to stabilize blood sugar at night, every person is different youll have to look for trends in your body, experiment with ways to lower glucose levels over a period of time, and learn what works best for your body.

  • Check your blood sugar before bed. If its already high, your blood sugar levels may remain high throughout the night. To address this, youll want to start by adjusting when you eat your evening meal and what it consists of, and how much mealtime insulin you take to cover it.

  • Avoid eating lots of food close to bedtime. For diaTribe writer Adam Brown, the key to staying in range overnight is low-carb, early dinners, with no snacking after dinner.

  • Consider eating less food at night and taking more basal insulin to cover your evening meal.

  • Check your blood sugar during the night, between midnight and 3am. If you were in range before bed but have high glucose levels between midnight and 3am, you may need to adjust your basal insulin dosage and timing. If you are low during that time, you may experience a rebound high blood sugar later on this is usually associated with overcorrecting the low.

    What Are Blood Sugar Levels

    Blood sugar levels, also known as blood glucose level, is the level of sugar/glucose present in the blood. Glucose is a simple version of sugar which comes from the food we eat. Therefore, the more food you consume with high sugar levels over a period of time, will typically increase your blood sugar level.

    Glucose comes from the foods we eat and its sugar content. When a person consumes a food with high sugar content, that is turned into glucose. The glucose is then absorbed into the bloodstream with the support of insulin. This is then distributed between the bodys cells and used as energy.

    Foods high in glucose include most carbohydrates and a handful of proteins and fats. Most foods contain glucose as it is simply a natural sugar that occurs in most dietary forms. However, it is carbohydrates that contain the most sugar and 100% of it turns into glucose, through the process mentioned above, once consumed. The concentration of glucose present in the blood will determine your blood sugar level.
