How Do I Measure Blood Sugar

If you have diabetes, you probably already keep a watchful eye on your blood sugar through the use of a continuous glucose monitor or a blood sugar meter . Blood sugar measurement is also typically included in routine lab work for people without diabetes — your physician will usually order a glycated hemoglobin test, which measures your average blood sugar over the past two to three months.

Say your A1C test comes back with no sign of diabetes — constantly measuring your blood sugar can still be helpful. For instance, some people experiment with using a CGM to see how their body responds to different types of food. However, it’s good to note that this is a fairly cost-intensive way of figuring out your nutrition, and writing down a food diary that includes how you felt after each meal will also help you figure out what to eat.

Check out these blood sugar monitors if you’re looking for recommendations on how to keep track of your levels at home.

What Are Normal Blood Glucose Levels In Healthy Individuals

Blood sugar levels can either be normal, high, or low, depending on how much glucose someone has in their bloodstream. Glucose is a simple sugar thats present in the bloodstream at all times. Normal blood glucose levels can be measured when someone fasts, eats, or after theyve eaten. A normal blood glucose level for adults, without diabetes, who havent eaten for at least eight hours is less than 100 mg/dL. A normal blood glucose level for adults, without diabetes, two hours after eating is 90 to 110 mg/dL.

Many factors affect blood sugar levels throughout the day:

  • Type of food consumed, how much, and when
  • Physical activity
  • Menstrual periods
  • Alcohol

An ideal blood sugar level for anyone without diabetes or prediabetes, regardless of age, in the morning should be less than 100 mg/dL. Remember, blood sugar levels can fluctuate throughout the day as a result of the factors previously mentioned.

Managing Blood Sugar Levels

Many people with diabetes must check their blood sugar levels daily with a glucose meter. This device takes a drop of blood, usually from a finger, and displays the sugar level within a few seconds.

People with type 1 diabetes will need to take insulin as their doctor recommends, usually several times a day.

Those with type 2 diabetes or gestational diabetes may need to change their diet and exercise habits. They may also need to take oral medications or insulin.

A number of strategies can help prevent hyperglycemia.

People should:

  • check their blood sugar levels as their doctor advises and take the correct amount of insulin, if they have type 1 diabetes
  • speak to their healthcare provider or dietitian about which foods to eat or avoid, how much to eat, and how often
  • take precautions to avoid infections, for example, through regular hand washing, as illness, such as a cold, can trigger a rise in blood pressure
  • plan their food intake and exercise to balance blood sugar levels
  • minimize stress, as far as possible, for example, through exercise, getting enough sleep, and stress-reducing activities such as meditation or yoga

Low blood sugar, or hypoglycemia, can happen when a person:

  • has certain medical conditions
  • does a lot of exercise
  • skips meals or eats too little

It can also be a side effect of diabetes medicines. Taking too much insulin can result in low blood sugar levels.

Symptoms of low blood sugar may include:

  • visit a doctor regularly

Here is a guide as to what an ideal reading is for each diabetic type and non-diabetic patients:

4 5.9 mmol/L< 7.8 mmol/L 4 5.9 mmol/L< 7.8 mmol/L

What Does Borderline Blood Sugar Levels Mean?

While a high glucose value can indicate diabetes, nondiabetics can also have higher values than normal. When researchers studied people wearing a continuous glucose monitor who did not have a diabetes diagnosis, they found 93% of individuals reached glucose levels that are considered dangerous, with 10% spending over 2 hours per day in these dangerous levels. Traditional glucose measurements, like a single point in time blood glucose value, are unable to capture these abnormalities.

There are actually several causes of high blood sugar unrelated to diabetes that the CDC recognizes. These include certain foods, like artificial sweeteners and coffee. Other factors like stress can do it, too. If you live with an endocrine or pancreatic condition, had surgery recently, or are experiencing intense physical stress , you may also see your glucose value rise.
