High Blood Sugar Over Time Leads To:

  • Kidney damage and kidney failure
  • Blood vessel damage that can cause heart attacks and strokes
  • Eye disease that can cause poor vision or blindness
  • Nerve damage that can cause pain like pins and needles in the feet
  • Sores on the feet or legs that do not heal and could lead to removal of a toe, foot, or leg

How Is It Determined If The Dawn Phenomenon Or Somogyi Effect Is Causing The High Blood Sugar Levels

Your doctor will likely ask you to check your blood sugar levels between 2 a.m. and 3 a.m. for several nights in a row. If your blood sugar is consistently low during this time, the Somogyi effect is suspected. If the blood sugar is normal during this time period, the dawn phenomenon is more likely to be the cause.

Some additional clues that the Somogyi effect may be the cause include nightmares, restless sleep and overnight sweating as these are all signs of low blood sugar levels.

    What If It Goes Untreated

    Hyperglycemia can be a serious problem if you don’t treat it, so it’s important to treat as soon as you detect it. If you fail to treat hyperglycemia, a condition called;ketoacidosis; could occur. Ketoacidosis develops when your body doesn’t have enough insulin. Without insulin, your body can’t use glucose for fuel, so your body breaks down fats to use for energy.

    When your body breaks down fats, waste products called;ketones;are produced. Your body cannot tolerate large amounts of ketones and will try to get rid of them through the urine. Unfortunately, the body cannot release all the ketones and they build up in your blood, which can lead to ketoacidosis.


    Ketoacidosis is life-threatening and needs immediate treatment. Symptoms include:

    • Shortness of breath

    Talk to your doctor about how to handle this condition.

    What Are The Symptoms Of Hyperglycemia

    The signs and symptoms include the following:

    • High blood sugar
    • High levels of sugar in the;urine
    • Frequent urination
    • Increased thirst

    Part of managing your diabetes is;checking your blood sugar;often. Ask your doctor how often you should check and what your blood sugar levels should be. Checking your blood and then treating high blood sugar early will help you avoid problems associated with hyperglycemia.

    Can Hyperglycemia Be Treated

    Your doctor may recommend a low-impact exercise program as your first line of defense. If youre already following a fitness plan, they may recommend that you increase your overall level of activity.

    Your doctor may also suggest that you eliminate glucose-rich foods from your diet. Its important to maintain a balanced diet and stick to healthy food portions. If you arent sure where to begin, your doctor can refer you to a dietician or nutritionist who can help you establish a diet plan.

    If these changes dont help lower your high blood sugar, your doctor may prescribe medication. If you have diabetes, your doctor may prescribe oral medications or change the amount or type of insulin youve already been prescribed.

    Different Levels And What They Mean

    What a High Blood Sugar Feels Like

    The ranges of safe levels of blood glucose depend on factors such as what time of day it is and when you last ate. Safe levels of blood sugar are high enough to supply your organs with the sugar they need, but low enough to prevent symptoms of hyperglycemia or complications of diabetes which follow the National Institute of Diabetes and Digestive and Kidney Diseases guides. Dangerous levels of blood glucose are outside of this range.

    The target levels can also vary if you have diabetes. For example, if you are diabetic and are monitoring your blood sugar, you might get a reading of 65 mg/dl. That is considered to be mild hypoglycemia, and you would be wise to eat 15 grams of fast-acting carbohydrates and retest your blood sugar in 15 minutes.;


    If you were not diabetic, you probably would not know that your sugar was low because you would not test and because you would not symptoms, and you would not act.

    That is fine because your body is capable, under normal circumstances, of raising your blood glucose to healthy levels when needed, even if you have not eaten. It is important to keep them in control to help prevent issues like heart disease or nerve damage.

    How To Test For Ketones

    You can use a urine test strip or blood ketone meter and ketone test strip to test for ketones at home. Testing either urine or blood is important, but when possible, a blood test is preferred because it gives you and your care team more precise information about your ketone levels. Because urine may have been in the bladder for some time, the results from these tests may show levels that are either higher or lower than the ketone levels that are actually circulating in your body. It is also very important to know that urine test trips degrade over time, so if you are using this method, you need to look at expiration dates carefully.


    Your diabetes care team can give you specific directions about when you should check for ketones, but in general, you should check for them when your blood glucose is 240 mg/dL or higher. You should also check for ketones if you notice any of the DKA symptoms listed above or if you are sick ; it is possible to have ketones while your blood glucose levels are within range .

    At-home urine test strips will change color to show the level of ketones in the urine. They typically report results as negative, trace, small, moderate or large. Blood ketone meters will provide a number that indicates the ketone levels. The following ranges are generally used:

    Why Does Blood Sugar Go Up At Night

    There are many factors that can cause your blood sugar to increase at night. For example: what food you ate during the day, how much and when you exercised, whether you ate snacks before bed, the timing of your insulin doses, and your stress level. You can experience different patterns of high blood sugar at night. You may start with high glucose when you go to bed, start the night in range but go high several hours later, or spend most of the night in range until the hours just before you wake up. By identifying your bodys patterns, you can figure out what is causing your high blood sugar and how to address it.

    Common causes of a glucose increase at night include:

    Blood Sugar Level Chart By Age

    Blood sugar levels tend to rise with age due to an increase in insulin resistance and decrease in insulin sensitivity. In one study by the National Health Institute , each extra decade of age was linked to a 2.7 mg/dl increase in fasting glucose, and a 4.5 mg/dl increase in 2-hour post-prandial glucose levels.

    Moderate To Severe High Blood Sugar

    What To Do When Blood Sugar Is High

    Moderate to severe symptoms of high blood sugar include:

    • Blurred vision.
    • Flushed, hot, dry skin.
    • Restlessness, drowsiness, or difficulty waking up.

    If your body produces little or no insulin , you also may have:

    • Rapid, deep breathing.
    • A fast heart rate and a weak pulse.
    • A strong, fruity breath odour.
    • Loss of appetite, belly pain, and/or vomiting.

    If your blood sugar levels continue to rise, you may become confused and lethargic. You also may become unconscious if your blood sugar levels are very high.

    Choose The Right Insulin

    The right insulin program can make or break your ability to control after-meal spikes. In general, insulins and other medicines that work quickly and for a short time will work better than those that work slowly over a prolonged period.

    For instance, rapid-acting insulin analogs , which start working 1015 minutes after injection and peak in about an hour, will cover the after-meal blood glucose rises much better than Regular insulin, which takes 30 minutes to begin working and 23 hours to peak.

    Newer ultra-rapid insulins, such as Fiasp , works even faster, with an onset and peak occurring 810 minutes earlier than traditional rapid-acting insulins.

    The way insulin is administered can dramatically affect its speed of action. Afrezza is an inhaled insulin formulation that can be used at mealtimes. Because the dry powder is absorbed through the lungs , its onset and peak are much earlier than injected insulin .

    Research has also shown that injected insulin can work much faster when the injection site is warmed. This can be accomplished by rubbing the site, immersing in warm water or exercising the muscle near the site. Warming the site causes the blood vessels near the skin to dilate, which allows the insulin to absorb more quickly. By the way, smoking causes the blood vessels to constrict, so quitting smoking might improve your post-meal blood sugar .

    What Causes Diabetes During Pregnancy

    Some women have diabetes before they get pregnant. This is called pregestational diabetes. Other women may get a type of diabetes that only happens in pregnancy. This is called gestational diabetes. Pregnancy can change how a woman’s body uses glucose. This can make diabetes worse, or lead to gestational diabetes.;

    During pregnancy, an organ called the placenta gives a growing baby nutrients and oxygen. The placenta also makes hormones. In late;pregnancy, the hormones estrogen, cortisol, and human placental lactogen can;block;insulin.;When insulin is blocked, its called insulin resistance. Glucose can’t go into the bodys cells. The glucose stays in the blood;and makes the blood sugar levels go up.

    Controlled Means Different Things To Different People

    Symptoms of high blood sugar | What Happens When Blood Sugar Is TOO High|

    Theres no one-size-fits-all recommendation for blood sugar control.

    The ADA says that a reasonable goal for many nonpregnant adults is to aim for an A1C level of less than 7. Yet some patients may be given a more stringent goal by their healthcare providers, such as 6.5, if thats reachable without harmful side effects, including hypoglycemia.

    On the other hand, if you are elderly, managing other health complications, or reliant on insulin, you may be given less stringent goals. It really becomes more important to just keep in the same place, says Rahil Bandukwala, DO, an endocrinologist at MemorialCare Saddleback Medical Center in Laguna Hills, California. Keeping A1C between 7.5 and 8.5 may be very reasonable for such a patient, Dr. Bandukwala adds, echoing the ADAs recommendations.

    Because elderly people are more likely to have blood sugar that swings too far downward, with fewer warning signs, managing their glucose too tightly can put them at greater risk for hypoglycemia, says Bandukwala. When you have low blood sugar, youre at a higher risk for becoming dizzy and falling or passing out, notes the ADA.
