Hyperglycemia (High Blood Sugar) is Dangerous<\/span><\/p>\n

High blood sugar (hyperglycemia) affects people who have diabetes.<\/span><\/p>\n

Several factors can contribute to hyperglycemia in people with diabetes, including food and physical activity choices, illness, nondiabetes medications, or skipping or not taking enough glucose-lowering medication.<\/span><\/p>\n

It’s important to treat hyperglycemia, because if left untreated, hyperglycemia can become severe and lead to serious complications requiring emergency care, such as a diabetic coma.<\/span><\/p>\n

Persistent hyperglycemia, in the long term, even if not severe, can lead to serious complications affecting your eyes, kidneys, nerves, and heart.<\/span><\/p>\n

Symptoms<\/span><\/p>\n

Hyperglycemia doesn’t cause symptoms until glucose values are significantly elevated.<\/span><\/p>\n

Symptoms of hyperglycemia develop slowly over several days or weeks. The longer blood sugar levels stay high, the more serious the symptoms become.<\/span><\/p>\n

However, some people who’ve had type 2 diabetes for a long time may not show any symptoms despite elevated blood sugar levels.<\/span><\/p>\n

Early signs and symptoms<\/span><\/p>\n

Recognizing early signs and symptoms of hyperglycemia can help you treat the condition promptly. Watch for:<\/span><\/p>\n

Blurred vision, Fatigue, Frequent urination, increased thirst, and Headache<\/span><\/p>\n

Later signs and symptoms<\/span><\/p>\n

If hyperglycemia goes untreated, it can cause toxic acids (ketones) to build up in your blood and urine (ketoacidosis).<\/span><\/p>\n

Signs and symptoms include:<\/span><\/p>\n

Fruity-smelling breath<\/span>
\nNausea and vomiting<\/span>
\nShortness of breath<\/span>
\nDry mouth<\/span>
\nWeakness<\/span>
\nConfusion<\/span>
\nComa<\/span>
\nAbdominal pain<\/span><\/p>\n

When to see a doctor<\/span><\/p>\n

Call 911 or emergency medical assistance if:<\/span><\/p>\n

You are sick and can’t keep any food or fluids down<\/span>
\nYour blood glucose levels are persistently high and you have ketones in your urine<\/span><\/p>\n

Make an appointment with your doctor if:<\/span><\/p>\n

You experience ongoing diarrhea or vomiting, but you’re able to take some foods or drinks<\/span>
\nYou have a fever that lasts more than 24 hours<\/span>
\nYour blood glucose is high even though you’ve taken your diabetes medication<\/span>
\nYou have trouble keeping your blood glucose within the desired range<\/span><\/p>\n

Causes<\/span><\/p>\n

During digestion, your body breaks down carbohydrates from foods \u2014 such as bread, rice, and pasta \u2014 into various sugar molecules.<\/span><\/p>\n

One of these sugar molecules is glucose, the main energy source for your body.<\/span><\/p>\n

Glucose is absorbed directly into your bloodstream after you eat, but it can’t enter the cells of most of your tissues without the help of insulin \u2014 a hormone secreted by your pancreas.<\/span><\/p>\n

When the glucose level in your blood rises, it signals your pancreas to release insulin.<\/span><\/p>\n

The insulin unlocks your cells so that glucose can enter and provide the fuel your cells need to function properly. Any extra glucose is stored in your liver and muscles in the form of glycogen.<\/span><\/p>\n

This process lowers the amount of glucose in your bloodstream and prevents it from reaching dangerously high levels. As your blood sugar level returns to normal, so does the secretion of insulin from your pancreas.<\/span><\/p>\n

Diabetes drastically lowers how insulin affects your body.<\/span><\/p>\n

This may be because your pancreas is unable to produce insulin (type 1 diabetes), or it may be because your body is resistant to the effects of insulin or doesn’t produce enough insulin to maintain a normal glucose level (type 2 diabetes).<\/span><\/p>\n

As a result, glucose tends to build up in your bloodstream (hyperglycemia) and may reach dangerously high levels if not treated properly.<\/span><\/p>\n

Insulin or other drugs are used to lower blood sugar levels.<\/span><\/p>\n

Risk factors<\/span><\/p>\n

Many factors can contribute to hyperglycemia, including:<\/span><\/p>\n

Not using enough insulin or oral diabetes medication<\/span>
\nNot injecting insulin properly or using expired insulin<\/span>
\nNot following your diabetes eating plan<\/span>
\nBeing inactive<\/span>
\nHaving an illness or infection<\/span>
\nUsing certain medications, such as steroids<\/span>
\nBeing injured or having surgery<\/span>
\nExperiencing emotional stress, such as family conflict or workplace challenges<\/span><\/p>\n

Illness or stress can trigger hyperglycemia because hormones produced to combat illness or stress can also cause your blood sugar to rise.<\/span><\/p>\n

Even people who don’t have diabetes may develop transient hyperglycemia during severe illness.<\/span><\/p>\n

Most people with diabetes need to take extra diabetes medication to keep blood glucose near normal during illness or stress.<\/span><\/p>\n

Complications<\/span><\/p>\n

Long-term complications<\/span><\/p>\n

Keeping your blood sugar in a healthy range can help prevent many diabetes-related complications. Long-term complications of untreated hyperglycemia can include:<\/span><\/p>\n

Cardiovascular disease<\/span>
\nNerve damage (neuropathy)<\/span>
\nKidney damage (diabetic nephropathy) or kidney failure<\/span>
\nDamage to the blood vessels of the retina (diabetic retinopathy), potentially leading to blindness<\/span>
\nClouding of the normally clear lens of your eye (cataract)<\/span>
\nFeet problems caused by damaged nerves or poor blood flow can lead to serious skin infections, ulcerations, and in some severe cases, amputation<\/span>
\nBone and joint problems<\/span>
\nTeeth and gum infections<\/span><\/p>\n

Emergency complications<\/span><\/p>\n

If blood sugar rises high enough or for a prolonged period of time, it can lead to two serious conditions.<\/span><\/p>\n

Diabetic ketoacidosis. Diabetic ketoacidosis develops when you don’t have enough insulin in your body.<\/span><\/p>\n

When this happens, sugar (glucose) can’t enter your cells for energy. Your blood sugar level rises, and your body begins to break down fat for energy.<\/span><\/p>\n

This process produces toxic acids known as ketones. E<\/span><\/p>\n

The excess ketones accumulate in the blood and eventually accumulate into the urine. Left untreated, diabetic ketoacidosis can lead to a diabetic coma and be life-threatening.<\/span><\/p>\n

Hyperglycemic hyperosmolar state.<\/span><\/p>\n

This condition occurs when people produce insulin, but it doesn’t work properly. Blood glucose levels may become very high. Because insulin is present but not working properly, the body can’t use either glucose or fat for energy.<\/span><\/p>\n

Glucose is then spilled into the urine, causing increased urination.<\/span><\/p>\n

Left untreated, the diabetic hyperglycemic hyperosmolar state can lead to life-threatening dehydration and coma. Emergency medical care is essential.<\/span><\/p>\n

Prevention<\/span><\/p>\n

The following suggestions can help keep your blood sugar within your target range:<\/span><\/p>\n

Follow your diabetes meal plan. If you take insulin or oral diabetes medication, it’s important that you be consistent about the amount and timing of your meals and snacks.<\/span><\/p>\n

The food you eat must be in balance with the insulin working in your body.<\/span><\/p>\n

Monitor your blood sugar. Depending on your treatment plan, you may check and record your blood sugar level several times a week or several times a day.<\/span><\/p>\n

Careful monitoring is the only way to make sure that your blood sugar level remains within your target range. Note when your glucose readings are above or below your goal range.<\/span><\/p>\n

Take your medication as prescribed by your doctor.<\/span><\/p>\n

Adjust your medication if you change your physical activity. The adjustment depends on the blood sugar test results and on the type and length of the activity.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
