What Are The Symptoms Of Low And High Blood Sugar

How Can I Treat And Manage Hyperglycemia

High and Low Blood Sugar Symptoms

People with both type 1 and type 2 diabetes can manage hyperglycemia by eating healthy, being active, and managing stress. In addition, insulin is a critical part of managing hyperglycemia for people with type 1 diabetes, while people with type 2 diabetes may need oral medications and eventually insulin to help them manage hyperglycemia.

If you dont have diabetes and have any of the signs and symptoms of hyperglycemia, call your healthcare provider. Together you can work to manage your hyperglycemia.

Tingling Hands And Feet

Over the years, hyperglycemia can begin to impact nerve function and eventually cause nerve damage, called neuropathy, Dr. Hatipoglu says. The most common kind of neuropathy is peripheral, according to the NIDDK, which affects the extremities. You might start noticing feelings of tingling, numbness, or burning in your hands, feet, arms, and legs, per the Mayo Clinic.

One of the challenges of managing diabetes is maintaining consistent blood sugar levels. Even with diligence, some situations can cause high blood sugar, or hyperglycemia, while others can bring on low blood sugar, or hypoglycemia.

After all, its not just carbohydrate intake that influences the amount of glucose coursing through your bloodstream when you have type 2 diabetes. Emotional stress and certain medications can increase your blood sugar levels, and a boost in activity can cause it to drop, says Megan ONeill, CDCES, a medical science liaison for diabetes care at Abbott healthcare company in Monterey, California. Sometimes people experience a spike in their blood sugar early in the morning due to the dawn effect, a temporary surge of hormones that occurs as the body prepares to wake, according to the Cleveland Clinic.

For people with diabetes, managing blood glucose levels is especially important, ONeill says. Levels that are too low or high can result in complications that affect your kidneys, heart, and vision, reduce your quality of life, require expensive interventions, or even be fatal.

How Is Dka Treated

DKA is very serious, but it can be treated if you go to the doctor or hospital right away. To feel better, a person with DKA needs to get insulin and fluids through a tube that goes into a vein in the body .

Let your parents or someone on your diabetes health care team know if you have any of these symptoms or are sick and donât know what to do to take care of your diabetes.

Always wear a medical identification bracelet or necklace that says you have diabetes. Then, if you are not feeling well, whoeverâs helping you will know to call for medical help. Medical identification can also include your doctorâs phone number or a parentâs phone number.

Low Blood Sugar: Warning Signs Ways To Treat And When To Call The Doctor

Physicians explain how to tell when your blood sugar is dangerously low, and how to take action to prevent complications.

According to the Centers for Disease Control and Prevention’s 2020 National Diabetes Statistics Report, 34 million people living in the United States had diabetes in 2018 — and amazingly, 21% of adults with diabetes did not even know they had it. The scariest part is that, if left untreated, diabetes can be deadly. In fact, it was the seventh leading cause of death in the year 2017.

And while normally associated with high blood sugar , diabetic folks can also experience hypoglycemia, or low blood sugar, alongside its own bevy of problems — including more severe and/or long-term effects like seizures, loss of consciousness, dementia and even death. Further, according to the Mayo Clinic, hypoglycemia can also cause low blood sugar in folks without diabetes due to a variety of conditions and medications.

So, needless to say, it’s important to maintain healthy blood sugar levels. But how is this done, especially if you don’t know the first thing about blood sugar?

How Do I Treat Low Blood Glucose

If you begin to feel one or more symptoms of low blood glucose, check your blood glucose level. If your blood glucose level is below your target or less than 70 mg/dL, follow these steps

  • Eat or drink 15 to 20 grams of glucose or carbohydrates right away. Examples include
  • four glucose tablets or one tube of glucose gel.
  • 1/2 cup of fruit juicenot low-calorie or reduced-sugar juice. If you have kidney disease, dont drink orange juice because it has a lot of potassium. Apple, grape, or cranberry juice are good options.
  • 1/2 can of sodanot low-calorie or reduced-sugar soda.
  • 1 tablespoon of sugar, honey, or corn syrup.
  • Wait 15 minutes and check your blood glucose level again. If your glucose level is still low, eat or drink another 15 to 20 grams of glucose or carbohydrates.
  • Check your blood glucose level again after another 15 minutes. Repeat these steps until your glucose level is back to your target range.
  • If your next meal is more than 1 hour away, have a snack to keep your blood glucose level within a range that is healthy for you. Try crackers or a piece of fruit.
  • Risk Factors For Prediabetes And Diabetes

    You have prediabetes if your blood sugar is higher than normal but not high enough to trigger a diagnosis of diabetes. The risk factors for prediabetes and diabetes are the same.

    Risk factors include:

    Lifestyle factors. Being overweight is a major risk factor for diabetes, especially if your waist size is large. If you smoke, eat an unhealthy diet, or have an inactive lifestyle, your risk goes up.

    Demographic factors. If you are over 45, your diabetes risk goes up. Your risk is also greater if you have a close family member with diabetes. Although it’s unknown exactly why, certain people â including those who are Black, Hispanic, Asian-American, or American Indian â are also at a higher risk for developing diabetes.

    Related conditions. You have a greater chance of getting diabetes if you have sleep apnea, a condition in which you repeatedly stop breathing while sleeping. Women who had diabetes while pregnant are at an increased risk. So are women with a condition called polycystic ovary syndrome.

    What Are The Signs & Symptoms Of Low Blood Sugar

    Different people may feel low blood sugar levels differently. People with low blood sugar may:

    • feel hungry or have “hunger pains” in their stomach
    • feel shaky or like they’re trembling
    • have a rapid heart rate
    • feel sweaty or have cold, clammy skin
    • have pale, gray skin color
    • have a headache
    • have seizures or convulsions
    • lose consciousness

    If you have diabetes, try to remember how your body reacts when your blood sugar levels are low. It may help you figure out when you’re having a low blood sugar level more quickly the next time.

    What Is Low Blood Glucose

    Early signs and symptoms of low blood sugar – Dr. Ramesh Babu N

    Low blood glucose, also called low blood sugar or hypoglycemia, occurs when the level of glucose in your blood drops below what is healthy for you. For many people with diabetes, this means a blood glucose reading lower than 70 milligrams per deciliter .1 Your number might be different, so check with your doctor or health care team to find out what blood glucose level is low for you.

    Mild High Blood Sugar

    If your blood sugar levels are consistently higher than your target range to 350 mg/dL in adults and 200 mg/dL to 240 mg/dL in children), you may have mild symptoms of high blood sugar. You may urinate more than usual if you are drinking plenty of liquids. Some people who have diabetes may not notice any symptoms when their blood sugar level is in this range. The main symptoms of high blood sugar are:

    • Increased thirst.
    • Fatigue.
    • Increased appetite.

    Young children are unable to recognize symptoms of high blood sugar. Parents need to do a home blood sugar test on their child whenever they suspect high blood sugar.

    If you donât drink enough liquids to replace the fluids lost from high blood sugar levels, you can become dehydrated. Young children can become dehydrated very quickly. Symptoms of dehydration include:

    • A dry mouth and increased thirst.
    • Warm, dry skin.

    Warning Signs Of Low Blood Sugar

    Hypoglycemia can cause both short- and long-term complications. Know the signs so that you can treat the condition as soon as you’re aware of it.

    As a person living with diabetes, you know how important it is to reduce blood sugar when it is too high, a phenomenon called hyperglycemia. But blood sugar that is too low, or hypoglycemia, is equally critical to avoid.

    “Hypoglycemia happens when the amount of blood glucose drops to a level that’s too low to sustain normal functioning,” says Erin Palinski-Wade, RD, CDCES, who is based in Sparta, New Jersey. “In most people, this is defined as a blood sugar level at or below 70 milligrams per deciliter .”

    Hypoglycemia is common among people with type 2 diabetes, according to a review published in June 2015 in the journal PLoS One. Individuals with the condition had an average of 19 mild or moderate episodes of hypoglycemia per year and nearly one severe episode per year on average, according to the researchers. Low blood sugar was particularly common among those taking insulin.

    This decrease in blood sugar levels can cause both short-term complications, like confusion and dizziness, as well as more serious issues, including seizures, coma, and, rarely, death, according to the American Diabetes Association .

    Hypoglycemia is usually the result of a too-high dose of insulin or a change in diet or exercise habits, according to Harvard Health Publishing.

    Do Not Drive When You Have Low Blood Sugar

    It’s very dangerous. If you’re driving and you have hypoglycemia symptoms, pull off the road, check your blood sugar, and eat a sugary food. Wait at least 15 minutes, check your blood sugar, and repeat these steps if necessary. Eat a protein and carbohydrate source before you drive on.

    Be prepared. Keep a sugar source in your car at all times for emergencies.

    Causes Of Low Blood Sugar

    There are many reasons why you may have low blood sugar, including:

    • Taking too much insulin.
    • Not eating enough carbs for how much insulin you take.
    • Timing of when you take your insulin.
    • The amount and timing of physical activity.
    • Drinking alcohol.
    • How much fat, protein, and fiber are in your meal.
    • Hot and humid weather.
    • Unexpected changes in your schedule.
    • Spending time at a high altitude.
    • Going through puberty.
    • Menstruation.

    Preventing A Low Blood Sugar Level

    If you have diabetes, you can reduce your chance of getting a low blood sugar level if you:

    • Check your blood sugar level regularly and be aware of the symptoms of a low blood sugar level so you can treat it quickly.
    • Always carry a sugary snack or drink with you, such as glucose tablets, a carton of fruit juice or some sweets. If you have a glucagon injection kit, always keep it with you.
    • Do not skip meals.
    • Be careful when drinking alcohol. Do not drink large amounts, check your blood sugar level regularly, and eat a carbohydrate snack afterwards.
    • Be careful when exercising eating a carbohydrate snack before exercise can help to reduce the risk of a hypo. If you take some types of diabetes medicine, your doctor may recommend you take a lower dose before or after doing intense exercise.
    • Have a carbohydrate snack, such as toast, if your blood sugar level drops too low while you’re asleep

    If you keep getting a low blood sugar level, talk to your diabetes care team about things you can do to help prevent it.

    Signs Of Hypoglycemic Unawareness

    Some people have no symptoms of low blood sugar. The only symptom you may have is confusion. Or you may become unconscious before anyone realizes you have low blood sugar.

    You may have hypoglycemic unawareness if you:

    • Cannot tell by your symptoms that your blood sugar is low.
    • Have low blood sugar several times a week.
    • Have type 1 diabetes, or have had type 2 diabetes for a long time.

    If you have hypoglycemic unawareness, test your blood sugar often, especially before activities like driving a car. Keep some glucose or sucrose tablets or solution or quick-sugar foods with you. If you take insulin, carry a glucagon emergency kit. You can also give friends and family instructions to treat low blood sugar.

    Medication Used To Correct A Low Blood Sugar

    This medicine is available in a kit for a low blood sugar emergency. Symptoms of a low blood sugar emergency are:

    • unconsciousness
    • patient is awake but unable to eat
    • the patient is having a seizure
    • the patients blood sugar is still less than 70 even after eating or drinking food containing sugar.

    Most often, glucagon is injected into the muscle. This type of glucagon is a powder in a bottle to which sterile water is added from a pre-filled syringe. The same syringe is then used to give the injection. Do not mix the glucagon with water unless you are going to inject the glucagon.

    Some glucagon can be given as a puff through the nose. Talk to your healthcare provider about which type may be best for you and your family. A family member or friend should know where you keep your glucagon kit and how to administer the medication. Read the directions that come with the kit with your friend or family member. That way you will be prepared if a low blood sugar emergency happens.

    For People With Type 2 Diabetes

    Low Blood Sugar Symptoms

    It is normal for blood glucose levels to go up and down throughout the day. An occasional high blood glucose level is not a problem. But if your blood glucose level remains high for a few days or if you are sick, contact your doctor or Credentialed Diabetes Educator.

    If not treated, high blood glucose levels can be dangerous and lead to Diabetic Ketoacidosis. Find out more here:

    How Does Hyperglycemia Occur Without Diabetes

    Similarly, hyperglycemia can occur in people with and without diabetes.

    If you dont have diabetes, various factors can cause high blood sugar, either suddenly or gradually. For example, some medical conditions increase blood sugar. These include polycystic ovary syndrome and Cushings syndrome.

    If you have an infection, your body might also release a high amount of stress hormones like adrenaline and cortisol. Too much of these hormones can interfere with your bodys ability to use insulin properly. As a result, your blood glucose level increases.

    Other factors that can lead to hyperglycemia without diabetes include obesity and a lack of physical activity. You might also have higher blood sugar if you have a family history of diabetes.

    When To Call The Doctor

    If signs of low blood sugar do not improve after you have eaten a snack that contains sugar, have someone drive you to the emergency room or call your local emergency number . DO NOT drive when your blood sugar is low.

    Get medical help right away for a person with low blood sugar if the person is not alert or cannot be woken up.

    When You Have Low Blood Sugar

    First, eat or drink 15 grams of a fast-acting carbohydrate, such as:

    • Three to four glucose tablets
    • One tube of glucose gel
    • Four to six pieces of hard candy
    • 1/2 cup fruit juice
    • 1 cup skim milk
    • 1/2 cup soft drink
    • 1 tablespoon honey

    Fifteen minutes after you’ve eaten a food with sugar in it, check your blood sugar again. If your blood sugar is still less than 70 mg/dL, eat another serving of one of the foods listed above. Repeat these steps until your sugar becomes normal.

    Does Everyone Have Symptoms From Hypoglycemia

    Some people dont have symptoms or dont notice them. Healthcare providers call that situation hypoglycemia unawareness. People with such a challenge arent aware when they need to do something about their blood sugar. Theyre then more likely to have severe episodes and need medical help. People with hypoglycemia unawareness should check their blood sugar more often.

    Signs & Symptoms Of Low Blood Sugar

    Keeping blood glucose levels in a healthy range can be challenging.

    When the amount of sugar in your blood has dropped below your target range , it is called low blood sugar .

    If your blood sugar has dropped, you may feel:

    • shaky, light-headed, nauseated
    • an increase in heart rate
    • sweaty, headachy
    • weak, drowsy
    • numbness or tingling on your tongue or lips

    Symptoms of very low blood sugar are more severe and can make you:

    • confused and disoriented
    • lose consciousness
    • have a seizure

    Make sure you always wear your MedicAlert® identification and talk to your doctor or diabetes educator about prevention and emergency treatment for severe low blood sugar.

    Why Is It Important To Treat High Blood Sugar

    Having high blood sugar for an extended period of time when you have diabetes can lead to complication affecting many different parts of the body. This can include the heart, eyes, nerves and kidneys.

    One complication of prolonged high blood sugar that is more common in type 1 than type 2 diabetes, is diabetic ketoacidosis , which can lead to coma or even death. When there is not enough insulin to move sugar into the bodys cells, fat is used to burn energy instead of sugar. Using fats instead of sugar can produce toxic chemicals called ketones.

    Some key signs and symptoms of DKA include:

    • High blood sugars
    • Thirst, dry mouth and tiredness
    • Rapid breathing or shortness of breath
    • A fruity smellto your breath
    • Nausea, vomiting and abdominal pain
    • Weakness and confusion
    • Loss of consciousness/coma

    Ketones can be detected using a blood ketone meter or urine ketone strips available for purchase at pharmacies. If DKA is recognized early, it may be treated at home, but if your blood sugar stays high, ketones are not lowering, or you are vomiting, it is important to go to the hospital immediately for treatment.

    The best way to prevent ketones is to manage your blood sugar levels and avoid hyperglycemia.
