Chronic hyperglycemia causes -

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.

Many people with diabetes, particularly those who use insulin, should have a medical ID with them at all times. In the event of a severe hypoglycemic episode, a car accident, or other emergency, the medical ID can provide critical information about the person's health status, such as the fact that they have diabetes, whether or not they use insulin, whether they have any allergies, etc.

Emergency medical personnel are trained to look for a medical ID when they are caring for someone who can't speak for themselves. Medical IDs are usually worn as a bracelet or a necklace. Traditional IDs are etched with basic, key health information about the person, and some IDs now include compact USB drives that can carry a person's full medical record for use in an emergency.

Your best bet is to practice good diabetes management and learn to detect hyperglycemia so you can treat it early—before it gets worse.

Breadcrumb Home Life with Diabetes Get the Right Care for You Hyperglycemia High Blood Glucose. What causes hyperglycemia? A number of things can cause hyperglycemia: If you have type 1, you may not have given yourself enough insulin.

If you have type 2, your body may have enough insulin, but it is not as effective as it should be. In fact, that's one reason why many people have undiagnosed diabetes. One of the most important jobs your kidneys do is keeping your blood sugar levels in check. Usually, your kidneys filter extra glucose from your blood and reabsorb it, so your urine should have little to no glucose in it.

If you are hyperglycemic, this process becomes much more difficult on your kidneys. They will need to work overtime to absorb the excess glucose. To keep your blood sugar in balance, your kidneys have to pull fluids from your tissues to water down dilute the sugar and excrete more glucose into your urine.

The more fluids your tissues lose, the stronger your urge to drink will be. If you find that no matter how much you drink, you still feel very thirsty or like your mouth is severely dry, it can be a sign of hyperglycemia.

More frequent trips to the bathroom, especially at night, can be a sign of high blood sugar. This happens because your kidneys are drawing extra water out of your tissues to dilute the extra sugar in your blood and get rid of it through urine.

When there's extra sugar in your bloodstream, it means that your body cannot use it for fuel. Your cells end up starved of energy, which causes you to feel more hungry than usual.

However, what you eat matters because the more carbohydrates you consume, the higher your blood sugar will be. High sugar levels force the body to pull fluid from your tissues, including the lenses of your eyes.

This can affect your ability to focus on what you're looking at and may lead to blurry vision. Normally, your cells absorb blood sugar for energy. When sugar stays in the blood instead of being taken to your cells, your cells don't have enough.

If your immune system is not working well as a result of high blood sugar and stress on the body, you might be more likely to get infections. Since yeast feeds on sugar, having elevated blood sugar levels can lead to an overgrowth of yeast.

For people with a vagina, frequent yeast infections are common if they have high blood sugar levels. People with a penis who have diabetes are three times more likely to develop erectile dysfunction than people with a penis who do not have diabetes. One reason why this may happen is that hyperglycemia damages the blood vessels that are needed to get or maintain an erection.

High blood sugar levels can also affect fertility and can complicate pregnancy. Hyperglycemia in pregnancy can be particularly damaging to a pregnant person and fetus. According to the ADA, uncontrolled diabetes in pregnancy carries risks like:.

In addition, diabetes in pregnancy may increase the risk of obesity and type 2 diabetes in offspring later in life. ADA guidelines for people with diabetes emphasize the importance of preconception counseling. This is very important to reduce the risk of serious complications in both the pregnant person and the developing fetus.

Dry, itchy skin, and wounds or cuts that are slow to heal can be a sign of hyperglycemia. Another sign that points to insulin resistance is acanthosis nigricans, a condition in which thick, velvety patches form in the folds or creases of areas like the neck.

While more research is needed, there is some evidence that higher blood sugar levels after meals in people with type 2 diabetes might be linked to certain negative mood symptoms, like irritability. Other studies have suggested that having higher blood sugar levels might be linked to feelings of anger and sadness among people with diabetes.

There are also symptoms that tend to occur when someone has had hyperglycemia for a long time, or when their blood sugar is extremely elevated.

These symptoms are more severe and long-lasting and can be a sign that a person needs medical care right away. Chronic hyperglycemia can lead to nerve damage in the stomach gastroparesis or delayed gastric emptying. This condition can cause nausea and very slow digestion. Stomach pain can also be a sign of diabetic ketoacidosis , a medical emergency that needs to be treated right away.

Unintentional weight loss is an important sign of elevated blood sugar, particularly in kids who are drinking and urinating often. Nausea, vomiting, fruity-smelling breath , deep and rapid breathing, and loss of consciousness are indications that you need to seek emergency help.

These symptoms can be warning signs of other diabetes-related conditions that can result in death if not treated immediately. Nerve damage in the extremities peripheral neuropathy , can happen over time in people with high blood sugar.

It causes symptoms like numbness, tingling, or pain in the hands, feet, or legs. Hyperglycemic hyperosmolar nonketotic coma HHNKC is a very serious complication of high blood sugar in people with type 1 or type 2 diabetes. It most often occurs in people who are non-insulin dependent type 2 diabetes.

It is typically brought on by an infection such as pneumonia , a urinary tract infection , or uncontrolled blood sugar. If left untreated, it can result in coma and even death.

Signs and symptoms include:. Hyperglycemia can lead to another dangerous condition called diabetic ketoacidosis DKA. This condition most commonly occurs in people who have type 1 diabetes. DKA happens when the body has little or no insulin to use. As a result, blood sugars rise to dangerous levels, and the blood becomes acidic.

This leads to cell damage. If it continues to progress, DKA can cause a person to fall into a coma or die. DKA needs immediate medical attention. People with DKA need to be monitored by a medical team and given intravenous fluids, electrolytes, and insulin. Like hyperglycemia, DKA tends to develop slowly.

The first symptoms are usually intense thirst and excessive urination. If left untreated, more severe symptoms can come on quickly and may include:.

Hyperglycemia may make it hard for the body to heal itself, leading to open sores, wounds, ulcers, and skin infections. You may notice these issues particularly on the feet.

High blood sugar may also lead to diabetic neuropathy , which is a form of nerve damage. According to the CDC , damage to the nerves develops slowly and may present as tingling, numbness, weakness, or sensitivity.

You may also experience impaired function for example, bladder leakage or severe pain. Hyperglycemia can lead to issues with vision, including blindness, if not addressed promptly.

You may not notice any issues with your vision right away, but high blood sugar levels can damage the blood vessels in the eyes, leading to swelling or blurry vision. HHS is a rare condition that appears most often in older adults with type 2 diabetes.

It may be accompanied by a trigger, such as an illness. When blood glucose levels are high, the kidneys excrete sugar into the urine, taking water with it. This causes the blood to become more concentrated, resulting in high sodium and blood glucose levels.

Without treatment, HHS may lead to life threatening dehydration and even coma. Contact a doctor if your blood glucose readings are consistently high, whether in a fasting state or after meals.

As well, let your doctor know if their recommended lifestyle measures are not making a difference in your readings. Make an appointment if you notice new or worsening issues with your vision or skin, or if you suspect you have nerve damage or other health issues that relate to high blood sugar.

Over time, though, it can cause noticeable symptoms, such as thirstiness and excessive urination. Both of these conditions are considered medical emergencies. Know the symptoms of hyperglycemia and these related conditions, and make it a habit to regularly check your blood glucose levels.

Good diabetes management and careful monitoring of your blood glucose levels are both very effective means for preventing hyperglycemia or stopping it before it gets worse. Read this article in Spanish.
