What Should Your Fasting Blood Sugar Levels Be?

It is not uncommon for your glucose levels to increase after a meal: you just ate food that may contain glucose, and now your body is working on getting it out of the bloodstream and into the cells. We know that we want to prevent excessive spiking of glucose levels because studies show that high post-meal glucose spikes over 160 mg/dl are associated with higher cancer rates. Spikes are also associated with heart disease. Repeated high glucose spikes after meals contribute to inflammation, blood vessel damage, increased risk of diabetes, and weight gain. Additionally, the data shows that the big spikes and dips in glucose are more damaging to tissues than elevated but stable glucose levels. Therefore, you should strive to keep your glucose levels as steady as possible, at a low and healthy baseline level, with minimal variability after meals.

Keeping your glucose levels constant is more complicated than just following a list of eat this, avoid that foods. Each person has an individual response to food when it comes to their glucose levels; studies have shown that two people can have different changes in their glucose levels after eating identical foods. The difference can be quite dramatic. One study found that some people had equal and opposite post-meal glucose spikes in response to the same food.

High Blood Sugar In The Morning: Is It The Dawn Phenomenon

If you have high blood sugar levels in the morning, you may be experiencing the dawn phenomenon, the name given to an increase in blood sugar that usually occurs between 2 a.m. and 8 a.m., according to the Mayo Clinic. One reason this occurs: During the early hours of the morning, our bodies secrete higher levels of a hormone called cortisol, says Dr. Spratt. When cortisol levels are high, it can make you more resistant to insulin, a hormone that helps regulate your blood sugar levels.

“Some people have a striking dawn phenomenon,” says Dr. Spratt. “You can look at their continuous glucose tracing and see that their blood sugar level suddenly goes up at 3 a.m.” If this is the case for you, your doctor may adjust your insulin medication or suggest you use an insulin pump .

Eat Less Sugar/refined Carbohydrates

The best way to keep blood sugar levels down without medication is to eat less sugar. The less sugar you consume, the smaller the metabolic response will bekeeping your pancreas and insulin levels healthy. You can cut back on sugars by limiting your intake of processed foods, sauces, fruit juices, candy, and soda, and paying attention to nutrition labels.

In turn, boosting your intake of fruits and veggies can have major benefits. Instead of sauces, opt for sugar-free seasonings and rubs, and try to drink water in place of other beverages. All of this can have immediate benefits for lower blood sugar.

Theres a ton of incredibly promising intermittent fasting research done on fat rats. They lose weight, their blood pressure, cholesterol, and blood sugars improve but theyre rats. Studies in humans, almost across the board, have shown that IF is safe and incredibly effective, but really no more effective than any other diet. In addition, many people find it difficult to fast.

But a growing body of research suggests that the timing of the fast is key, and can make IF a more realistic, sustainable, and effective approach for weight loss, as well as for diabetes prevention.

Factors That Can Affect Blood Sugar Levels

There are many factors that can affect your blood glucose levels. Since a fasting blood glucose test provides a baseline, its important to understand how certain factors can raise or lower your levels throughout the day.

The National Center for Biotechnology Information notes that the following factors can raise blood sugar levels:

  • Dehydration
  • Not taking enough insulin or oral diabetes medications
  • Side effects from other medications, such as steroids or antipsychotics
  • Consuming too much food that contains more carbohydrate than usual
  • Being sick, which causes your body to release hormones to fight illness
  • Stress, which can produce hormones that raise blood glucose levels
  • Short- or long-term pain that causes your body to release hormones that raise blood glucose levels
  • Menstrual periods, which cause changes in hormone levels

Alternatively, NCBI lists the following as factors that can cause low blood sugar levels:

  • Not eating enough food, such as a meal or snack with fewer carbohydrate than usual or missing a meal or snack
  • Consuming alcohol, especially on an empty stomach
  • Taking too much insulin or oral diabetes medications
  • Side effects from other medications
  • More physical activity or exercise than usual, which makes your body more sensitive to insulin and can lower blood glucose levels

Low Blood Sugar Levels

Blood sugar that is too low can cause symptoms such as:

  • shaking and sweating
  • headache
  • tiredness

As with low blood sugar, high blood sugar may cause loss of consciousness or seizures if people leave them untreated. Persistent high levels can increase the risk of serious complications that doctors relate to diabetes, such as cardiovascular disease.

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.

How Can One Tell If I Have Diabetes By Examining My Blood

Your body converts sugar, also called glucose, into energy so your body can function. The sugar comes from the foods you eat and is released from storage from your bodys own tissues.

Insulin is a hormone made by the pancreas. Its job is to move glucose from the bloodstream into the cells of tissues. After you eat, the level of glucose in the blood rises sharply. The pancreas responds by releasing enough insulin to handle the increased level of glucose moving the glucose out of the blood and into cells. This helps return the blood glucose level to its former, lower level.

If a person has diabetes, two situations may cause the blood sugar to increase:

  • The pancreas does not make enough insulin
  • The insulin does not work properly

As a result of either of these situations, the blood sugar level remains high, a condition called hyperglycemia or diabetes mellitus. If left undiagnosed and untreated, the eyes, kidneys, nerves, heart, blood vessels and other organs can be damaged. Measuring your blood glucose levels allows you and your doctor to know if you have, or are at risk for, developing diabetes.

Much less commonly, the opposite can happen too. Too low a level of blood sugar, a condition called hypoglycemia, can be caused by the presence of too much insulin or by other hormone disorders or liver disease.

How Do Doctors Diagnose Prediabetes

How to Measure Your Blood Sugar When You Are Fasting? And What It Tells You

Diabetes is a measure of levels of sugar in your bloodstream. Physicians check this in;two different ways:;

1. A standard blood glucose test

This requires you to fast before a blood test, so your PCP or endocrinologist can check the level of glucose in your bloodstream at any given time. Ideally, fasting glucose levels should be 99 mg/dL or lower. If your fasting blood glucose levels are between 100 and 125mg/dL, it could be considered prediabetes, says Martha McKittrick RD. I like to have people get a second test done, to make sure its accurate, she says. A reading higher than 126 mg/dL indicates diabetes.

2. An A1C blood test;

The test for A1C, or hbA1c, is a non-fasting blood test that measures the average amount of glucose in your blood stream over a period of three months and is measured in percentages. A healthy percentage is under 5.7%. A result between 5.7 and 6.4% suggests prediabetes. Anything higher than 6.5% indicates diabetes.

A person who is prediabetic may not always show symptoms. In fact, the majority dont. Oftentimes, an asymptomatic person will only get a prediabetes diagnosis if their general physician gives them a blood glucose test or checks their hbA1C readings and finds an atypical result.;

Although most people dont show noticeable symptoms of prediabetes, if you are experiencing fatigue, excessive hunger, excessive thirst, and frequent urination, its better to be safe than sorry. Make an appointment to get your glucose levels checked ASAP.

When To See A Healthcare Provider

Getting professional medical advice from a healthcare provider like an endocrinologist is the best way to learn more about whether your blood sugar levels are where they should be. Not getting proper treatment for low or high blood sugar levels can be serious and lead to health complications, especially for those with diabetes. Diabetes complications include nerve damage, kidney disease, heart disease, or heart attacks.;;

If you see a healthcare provider about your blood sugar levels, be prepared to answer questions about risk factors like what you eat, how much you exercise, and about your family history. Some healthcare providers may want to take a blood sample to test your blood sugar levels. They may also order an A1C test, which is a blood test that measures blood sugar levels over several months. You may have to fast eight hours beforehand to get accurate test results, so its always a good idea to check before your appointment.;;;;;;;;

If your blood sugar level goes above 250 mg/dL, you should go to the ER for immediate medical attention, says Dr. Tarugu. Emergency rooms are equipped to handle high blood sugar levels and can administer treatments like insulin therapy and fluid or electrolyte replacement.;;;;;;;;;

Diagnosing Prediabetes Type 2 And Type 1 Diabetes

Depending on which country or medical organization you ask, the qualifying numbers for normal versus prediabetes versus diagnosed type 1 or type 2 diabetes can vary slightly. The following blood sugar and A1c the general results are used to diagnosed prediabetes and diabetes according to sources including the American Diabetes Association and Diabetes UK:;;

Prediabetes

  • HbA1c: 5.7 to 6.4 percent
  • Fasting: 100 to 125 mg/dL
  • 2 hours after a meal: 140 mg/dL to 199 mg/dL

Type 1 or 2 diabetes

  • HbA1c: 6.5 percent or higher
  • Fasting: 126 mg/dL or higher
  • 2 hours after a meal: 200 mg/dL or higher

Please note: Type 1 diabetes tends to develop very quickly which means that by the time symptoms are felt, blood sugar levels are generally well above 200 mg/dL all the time. For many, symptoms come on so quickly they are dismissed as the lingering flu or another seemingly ordinary virus.

By the time blood sugar levels are tested, many newly diagnosed type 1 patients will see levels above 400 mg/dL or higher. If you do suspect that you or a loved-one has type 1 diabetes, visit your primary care or urgent care immediately and ask for a urine test to measure ketones in addition to testing blood sugar levels and A1c.

What Is The Fasting Blood Sugar Test Used For

Overview on Fasting blood glucose level

The fasting blood sugar test is also used to test the effectiveness of different medication or dietary changes on people already diagnosed as diabetic

Fasting blood sugar levels are measured by taking a blood test after a period of fasting, usually of 8 hours without food. Typically, fasting blood glucose levels are taken in the morning before any breakfast is eaten. When having your fasting blood glucose levels take, you should not have any drinks apart from water during the period of fasting.

A fasting blood glucose test can be useful to see how well the body is able to manage blood sugar levels in the absence of food. When we do not eat for several hours, the body will release glucose into the blood via the liver and, following this, the bodys insulin should help to stabilise blood glucose levels.

A fasting blood glucose test therefore shows:

  • Whether the body is able to bring down the raise in blood glucose levels from the previous meal
  • How effectively the body copes with its own release of glucose

The target for fasting blood glucose levels are the same as the targets for before meal readings.

  • For adults with diabetes, the target level is between 4 and 7 mmol/l
  • For children with diabetes, the target level is between 4 and 8 mmol/l

However, ;some people may be set individual targets, by their doctor, that differ to the above levels.

Official Fasting Blood Sugar Ada Recommendation For Someone With Diabetes

The American Diabetes Association recommends a fasting blood sugar target of 80 to 130 mg/dl for most nonpregnant adults with diabetes. However, the fasting blood sugar target may need to be individualized for certain people based on such factors as duration of diabetes, age and life expectancy, cognitive status, other health conditions, cardiovascular complications, and hypoglycemia unawareness. Its important that people with diabetes discuss their target blood sugar goals with their healthcare provider.
