What Is A High Blood Sugar Reading




How High Must That Number On The Glucose Meter Be In Order For It To Warrant A Trip To The Emergency Room Stat

Should you zip to the emergency room if your blood sugar is over 300 no matter how you feel?

First of all, if you’re fearing that your body is in urgent need of medical care due to a very high blood sugar, don’t drive; have someone drive you.

Blood Sugar Numbers and Emergency Room Visits


“It’s not a number; it’s how you feel,” says Susan L. Besser, MD, with Mercy Medical Center, Baltimore, and Diplomate American Board of Obesity Medicine and board certified by the American Board of Family Medicine.

“Some diabetics walk around with a sugar in the 400’s and really don’t have many symptoms, whereas others go into a coma at a sugar in the upper 200’s,” continues Dr. Besser.

“Don’t just look at the number. Look at the person. And if you aren’t sure, call your PCP first. He or she knows you best and can advise you what to do.”

Nevertheless, if you learn that your blood sugar is in the 400’s simply because it was time to take a scheduled glucose reading, but you feel perfectly fine, it’s not necessary to go to the emergency room.


How Do I Prepare For The Plasma Glucose Level Test And How Are The Results Interpreted

To get an accurate plasma glucose level, you must have fasted for at least 8 hours prior to the test. When you report to the clinic or laboratory, a small sample of blood will be taken from a vein in your arm. According to the practice recommendations of the American Diabetes Association, the results of the blood test are interpreted as follows:

Fasting blood glucose level

  • If your blood glucose level is 70 to 99* mg/dL . . .
  • What it means: Your glucose level is within the normal range
  • If your blood glucose level is 100 to 125 mg/dL . . .
  • What it means: You have an impaired fasting glucose level . . .
  • If your blood glucose level is 126 mg/dl or higher on more than one testing occasion
  • What it means: You have diabetes
  • *Values between 50 and 70 are often seen in healthy people

    **The condition of “prediabetes” puts you at risk for developing Type 2 diabetes, high blood pressure, and blood lipid disorders

    The Classic Symptoms Of High Blood Sugar Are Polyuria Polydipsia And Polyphagia

    In plain English, that means excessive urination, excessive thirst, and excessive hunger. Any doctor who hears this trio of complaints will reach for a blood glucose meter. But often, the person experiencing these symptoms doesn’t notice them right away. This is partly because they often creep up on a person in a gradual fashion, and partly because the signs and symptoms of high blood glucose aren’t well known among people who don’t have diabetes — or don’t know they have diabetes.

    What Is The Name For The Hormone That Helps The Body Use Sugar For Energy


    The hormone that helps the body use sugar for energy is called insulin. Insulin is made by the body in the pancreas and when the body cannot produce enough insulin on its own, it needs to be taken by injection or other means. Everyone who has type 1 diabetes must take some form of insulin therapy. Some people with type 2 diabetes will also need insulin supplementation. There are different types of insulin available, and they differ in chemical structure and how long they last in the body.

    What Is A Dangerous Blood Sugar Reading And What Should You Do About It

    High Blood Sugar Glucose Reading over 500

    How high is high and how low is low – find out so that next time you know how to handle an emergency.

    Your blood sugar levels don’t stay constant throughout the day. They vary, rising and falling before and after you have a meal, exercise, or take your medication. People who do not have diabetes don’t feel the difference very much, as their variations remain within a certain range. But if you have diabetes, you may unexpectedly experience blood glucose levels that are acutely higher or lower than usual, which can be dangerous.It is important for you to be able to recognise the symptoms of high blood sugar — hyperglycaemia, and low blood sugar — hypoglycaemia, and know how to treat them quickly before they can lead to disastrous complications. The best way to do this is to frequently self-monitor blood glucose levels with a glucometer.


    According to Dr Ketan K Mehta, Consulting Physician, CardioPulmonologist & Diabetologist at Health Harmony, Mumbai, “Blood sugar levels are a marker of diabetes complications. Too high or too low levels of blood sugar values are detrimental. An important aspect of managing diabetes is self-monitoring of blood sugar levels. But do more than only monitoring blood sugar levels. Go the extra mile and use smartphone app-based programmes to keep track of your blood sugar levels and learn to get them under control by managing your diet, activity levels and weight.”

    How High Is Too High For A Blood Sugar Reading And What Are The Dangers

    A high blood sugar level is defined as a reading of greater than 130 mg/dL after 8 hours of fasting or a reading of greater than 180 mg/dLafter eating a meal, according to WebMD. Frequent high blood sugar can cause damage to the nerves, blood vessels and other organs.

    Although diabetes is the most common reason for high blood sugar, there are many other causes, such as infection, injury or even just eating more sugar than normal, notes MedicineNet. When symptoms such as increased thirst, increased urination and weight loss accompany high blood sugar, diabetes is diagnosed, states WebMD.


    High blood sugar coats blood cells, which in turn causes the cells to hinder circulation, explains the Mayo Clinic. The small blood vessels are particularly susceptible to these problems, so damage to the eyes, kidneys and feet are common in those with chronically high blood sugar. Controlling high blood sugar can prevent or lessen complications such as heart attack, stroke, eye damage that can lead to blindness, nerve damage in the hands and feet, kidney damage, gum disease and tooth loss. Damage can begin when blood sugar is higher than normal, but not high enough to be considered diabetes. Increasing physical activity and losing weight can help decrease blood sugar in people who are at risk for developing diabetes.

    What Level Of Blood Sugar Is Dangerous & How To Bring It Down Quickly

    High blood sugar is a condition which occurs if the transport of the sugar from the blood to the cells is affected. And this condition if left unchecked can lead to a dangerous rise in the sugar level, which can further invite many other problems and complications. So what level of blood sugar is dangerous and how to bring it down quickly? It is important to know about this and the ways to deal with it.


    Symptoms Signs Causes Of Levels Of High Blood Sugar In The Blood

    High blood sugar or hyperglycemia is an abnormally high blood sugar level in the blood. Hyperglycemia is a hallmark sign of diabetes and prediabetes.

    Signs and symptoms of hyperglycemia include blurred vision, headaches, hunger, and …

      The normal ranges for blood sugar levels in adults who do not have diabetes before eating or fasting the range begins at 72-99mg/dL while fasting ranges for those being treated for type 1 or type 2 diabetes range from 80 -130 mg/dL. According to the American Diabetes Association normal blood sugar levels before and after eating should be 80-130 mg/dL before eating a meal , and less than 180 mg/dL about 1-2 hours after eating a meal

      High blood sugar ranges for people who don’t have diabetes begins at 140 mg/dL or greater while for those being treated for diabetes, the high range begins at 180 mg/dL , called hypoglycemia.


        People Who Are Obese Are More Likely To Develop Type 2 Diabetes

        Those with increased body fat are at higher risk for type 2 diabetes. Risk is greatest for those with excess fat carried around the waist. These people are also at increased risk for hypertension, high cholesterol levels, and heart disease compared with those who are lean or carry fat around the hips.

        The 411 On A1c: Normal A1c Levels And 15 Ways To Lower High A1c

        SingleCare TeamLindsey Hudson, APRN, NP-C, CDCES


        The hemoglobin A1C test is the closest thing to a diabetes scorecard you can find. Whether someone has had diabetes mellitus for years or if they have just been diagnosed, they have probably heard about this test. Unlike blood sugar meters people use at home, the A1C measures an average blood sugar level over the past several months by analyzing how many of a patient’s hemoglobin cells have glucose attached to them. The test results keep track of how well a person is managing his or her diabetes. 

        How To Prevent Hyperglycaemia And Lower Your Blood Sugar Levels

        Testing your blood sugar levels regularly can help you spot the signs of hyperglycaemia. But there are some steps you can take to either prevent a hyper from happening or to bring down your blood sugar levels.

        You can start by making sure you are aware of your carbohydrate portions and how they may be affecting your blood sugar levels after eating. Carb countingis one of the ways you can manage this. Avoid foods that have a high glycemic index and choose low GI foods that can help manage your blood sugar levels more effectively. Increase the fibre in your diet. This can help slow down carbohydrate digestion, which can help limit the rise in your blood sugars.


        Try to maintain a healthy weight as this promotes regular blood sugar levels in the body. Be as active as possible, regular exercise can help your body process more of the sugar.

        Remember to take your insulin and other diabetes medication, and always take them correctly. Continue to take your diabetes medication even if you are ill and not eating.

        Concentrate on your emotional wellbeing, get a quality night’s sleep and find ways to manage your stress. Stress can cause hormones to be released, which keep your blood sugar levels high.

        If your blood sugar levels continue to be high, or you’re unsure of what to do, contact your doctor for further guidance.

        High Blood Sugar: 13 Reasons Your Glucose Levels Are Rising

        High Blood Sugar Glucose Reading over 500


        It’s a fact of life that blood sugar fluctuates throughout the day. These ups and downs depend on a handful of factors, like when you wake up, what you eat, the medications you take, and how you manage stress. So, some variation is normal, to the point that you might not even notice it. 

        Ignoring blood sugar level changes altogether, though, means you’re ignoring a valuable marker of your health. Especially if you start to have new or unfamiliar symptoms like fatigue, thirst, or brain fog . Learning these symptoms and their causes will give you the tools to better understand your own body, then take the right actions for better long-term metabolic health.      

        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 that’s present in the bloodstream at all times. Normal blood glucose levels can be measured when someone fasts, eats, or after they’ve eaten. A normal blood glucose level for adults, without diabetes, who haven’t 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.   

        How To Calculate Your Blood Sugar Level: The Complete Guide

        To get an accurate reading of your blood sugar level, the best and most effective method is using a glucose meter. This will involve a small prick in your finger so receive a blood sample. The strip is then inserted into the meter and tested. 

        You may be wondering what your reading should be. There is no ‘normal’ reading, an ideal reading differs from person to person. Everyone will get different readings at different times of the day. However, there is a rough range to determining a low, normal and high blood sugar level. Blood sugar level is read in mmol/L, which stands for millimoles per liter. Here is a guide as to what an ideal reading is for each diabetic type and non-diabetic patients:

        Child
        4 – 5.9 mmol/L<7.8 mmol/L4 – 5.9 mmol/L<7.8 mmol/L

        It is advised to check it regularly if you are concerned, show regular symptoms or have diabetes. You should check before meals, exercise, before bedtime and after driving. Everyone is different so it is best to ask your doctor if you are unsure how many times and when you should check your blood sugar levels.

        Research shows that over 50% who try to estimate their blood sugar level reading are incorrect. This may be due to over underlying medical conditions that did not know they had or poor lack of judgement. Therefore, this suggests it is very important to test at home to check in on your levels regularly to avoid any unnecessary future complications. 

        What Are Target Blood Sugar Levels For People With Diabetes

        A target is something that you aim for or try to reach. Your health care team may also use the term goal. People with diabetes have blood sugar targets that they try to reach at different times of the day. These targets are:

        • Right before your meal: 80 to 130
        • Two hours after the start of the meal: Below 180

        Talk with your health care team about what blood sugar numbers are right for you.

        Target Blood Sugar Ranges For Pregnant People With Diabetes

        Blood sugar targets during pregnancy are lower due to hormonal influences. The ADA, AACE, and Joslin Diabetes Center have slightly different guidelines for target blood sugar levels during pregnancy. In general, pregnant women with diabetes will want to follow individual guidelines provided by their endocrinologist.

        The ADA recommends maintaining blood sugar levels of 95-140 mg/dL for pregnant women. However, some providers recommend an even tighter goal of blood glucose levels below 89 mg/dL before a meal and below 120 mg/dL after a meal.

        To keep close tabs on levels, most diabetes specialists recommend that women with diabetes during pregnancy check their blood sugar:

        • First thing in the morning
        • Before all meals

        High Blood Sugar Symptoms: Causes Signs And Taking Control

        If you’ve had diabetes for any length of time at all, you’ve probably seen lists of the signs and symptoms of high blood sugar dozens of times. Doctors and diabetes educators hand them out. Hundreds of websites reprint them. Most diabetes books list them. You likely know some of the items on the list by heart: thirst, frequent urination, blurry vision, slow healing of cuts, and more.

        But have you ever stopped to wonder why these symptoms occur? How does high blood sugar cause frequent urination, make your vision go blurry, or cause all of those other things to happen? Here are some answers to explain what’s going on in your body when you have high blood sugar.

        Target Blood Sugar Levels For Pregnant Women With Diabetes

        It’s possible for diabetes to cause problems during pregnancy. For example, according to the Centers for Disease Control and Prevention, women with type 1 and type 2 diabetes who have uncontrolled blood sugar levels could experience an increased risk of having a premature baby, needing a C-section and more.

        Gestational diabetes — a type of diabetes that occurs in a pregnant woman who has never been diagnosed with diabetes before — can also cause complications. These include giving birth to a baby who is larger than average and an increased risk of needing a C-section. The ADA suggests that pregnant women shoot for a target fasting blood sugar level of 95 mg/dL or less before a meal.

        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 .

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

        High Blood Sugar Over 300mg Test Readings Glucose Level, 1 ...

        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 body’s 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.

        Can Drinking A Lot Of Water Lower Your Blood Sugar Levels

        Although feeling very thirsty is a symptom of a hyper, drinking a lot of water will not bring your blood sugar levels down. It will only help to reduce your risk of dehydration.

        It’s important that you take your diabetes medication to bring your blood sugar levels down. If you have consistently high blood sugar levels, you will need to follow the advice below and speak to your diabetes healthcare team.

        What Are The Symptoms Of Dangerous Levels Of Blood Sugar

        A patient with high blood sugar presents the symptoms such as a dry mouth, fatigue, dry, and itchy skin and an increased appetite. Some people also experience being more thirsty and increased frequency of urination, especially at night.

        If not corrected early it can lead to symptoms of dangerous levels of blood sugar like difficulty in breathing, dizziness, rapid weight loss and confusion of mind. Blood sugar level of 300 or above is dangerous and if not treated a condition known as diabetic ketoacidosis or diabetic coma can occur.

        What Are The Signs & Symptoms Of High Blood Sugar Levels

        Signs of high blood sugar levels include:

        • Peeing a lot: The kidneys respond by flushing out the extra glucose in urine. People with high blood sugar need to pee more often and in larger amounts.
        • Drinking a lot: Someone losing so much fluid from peeing that often can get very thirsty.
        • Losing weight even though your appetite has stayed the same: If there isn’t enough insulin to help the body use glucose, the body breaks down muscle and stored fat instead in an attempt to provide fuel to hungry cells.
        • Feeling tired: Because the body can’t use glucose for energy properly, a person may feel unusually tired.

        What Else Can I Do To Help Manage My Blood Sugar Levels

        Eating a healthy diet with plenty of fruit and vegetables, maintaining a healthy weight, and getting regular physical activity can all help. Other tips include:

        • Keep track of your blood sugar levels to see what makes them go up or down.
        • Eat at regular times, and don’t skip meals.
        • Choose foods lower in calories, saturated fat, trans fat, sugar, and salt.
        • Track your food, drink, and physical activity.
        • Drink water instead of juice or soda.
        • Limit alcoholic drinks.
        • For a sweet treat, choose fruit.
        • Control your food portions .

        What If I Have Trouble Getting To My Blood Sugar Goals

        There may be times when you have trouble reaching your blood sugar goals. This does not mean that you have failed. It means that you and your health care team should see if changes are needed. Call your health care team if your blood sugar is often too high or too low. Taking action will help you be healthy today and in the future.
