High Blood Sugar Causes

7 Alarming Signs Your Blood Sugar Is Too High

You may be thinking that hyperglycemia can happen just from eating a super-sugary food, but its not really as simple as that. Sure, eating a lot of sugar or carbs can elevate your blood sugar level, but thats typically when your pancreas kicks into gear and creates insulin to move that glucose into cells throughout the body.

But when someone has diabetes, this finely tuned system gets thrown out of whack. In type 2 diabeteswhich accounts for 90% to 95% of diabetes in adults, according to the CDCthe body either cant make enough insulin or cant utilize insulin well, according to the NIDDK. If someone has prediabetes, their blood glucose will be higher than normal but not quite in the type 2 diabetes range yet, per the NIDDK. And in type 1 diabetes, the body does not make insulin or makes very little.

In any case, the result is extra sugar hanging around the bloodstream, making you feel like total crap in the short term and putting your health at risk in the long term.

How To Prevent It

If you work to keep your blood sugar under control — follow your meal plan, exercise program, and medicine schedule — you shouldnât have to worry about hyperglycemia. You can also:

  • Know your diet — count the total amounts of carbs in each meal and snack.
  • Test your blood sugar regularly.
  • Tell your doctor if you have repeated abnormal blood sugar readings.
  • Wear medical identification to let people know you have diabetes in case of an emergency.

Being ill can upset your diabetes management, so you need to know what to do to keep your blood glucose levels as close to target as possible. Some people will know these as diabetes sick day rules.

Youll need to know how to manage insulin or other diabetes medications, blood or urine tests, and your diet, and how to manage your diabetes when youre sick. This is really important if you go into hospital or if you need to take steroids as part of your treatment. Always tell the healthcare professionals treating you that you have diabetes.

Postprandial Or Reactive Hyperglycemia

11 Symptoms Of High Blood Sugar That Is Really Worrying ~ Healthcopia

This type of hyperglycemia occurs after eating .

During this type of hyperglycemia, your liver doesn’t stop sugar production, as it normally would directly after a meal, and stores glucose as glycogen.

If your blood glucose level 1-2 hours after eating is above 180mg/dL, that signals postprandial or reactive hyperglycemia.

However, it’s not just people with diabetes who can develop hyperglycemia. Certain medications and illnesses can cause it, including beta blockers, steroids, and bulimia. This article will focus on hyperglycemia caused by diabetes.

Take Your Insulin As Prescribed

High blood sugar occurs when your body has too little insulin, or your body cant use insulin properly. Administering insulin can bring your blood sugar levels down.

Talk to your doctor about how much rapid-acting insulin you should administer when your blood sugar is high.

You may want to check your blood sugar about 1530 minutes after taking insulin to make sure your blood sugar is going down and that its not dropping too low.

What Are Normal Blood Sugar 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 thats present in the bloodstream at all times. Blood glucose levels can be measured at any time, for example, when someone fasts , before they eat, or after theyve eaten. A normal blood glucose level for adults, without diabetes, who havent 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

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.

What Are The Risks Of Hyperglycemia

Hyperglycemia can be a sign that your body isnt getting enough insulin. It is normal for patients with T1D to get hyperglycemia, and most of the time this is simply treated with insulin. If the body does not have insulin for approximately 8 hours, you could develop a condition called diabetic ketoacidosis, or DKA.

In DKA, your body breaks down fat for energy because it doesnt have enough insulin to use the sugar in your blood. This produces chemicals called ketones, which make your blood more acidic.

DKA is dangerous. Too much acid in your blood can make you pass out or even cause death.

Causes Of High Blood Sugar

What Are The Alarming High Blood Sugar Symptoms & Signs?

The leading causes of high blood sugar or hyperglycemia include:

Diet: Glucose comes from food, so what you are eating causes high blood sugar. Carbohydrates are the most common culprit as they are broken down into glucose very quickly in the body. High-sugar foods, high-fat foods, and processed foods also cause blood glucose spikes and should be replaced with healthier options.

Stress: When you are stressed, more stress hormones and chemicals are released, which drives blood sugar levels up too. If the stress is only temporary, this is not a serious issue, but if you experience chronic stress or an anxiety disorder, you may experience high blood sugar levels more often.

Metabolic Syndrome: These are a collection of conditions that occur at the same time and increase your risk for type 2 diabetes. High blood pressures, excess fat around the waist, and high cholesterol or triglycerides are examples of these conditions. When these occur in the body together, your risk for diabetes increases as does your blood sugar and the risk for potential complications.

Physical Inactivity: A lack of physical activity contributes to elevated blood sugar. When you are physically active each day, insulin works more efficiently, and your blood sugar can be maintained.

Managing Your Diabetes Devices

If you are using an insulin pump, talk to your diabetes team about how to best manage hyperglycemia. In general, be sure to check your pump first. Make sure all parts are connected and working correctly. Check your bolus history and temporary basal rate. Also check your insulin to make sure it has not expired or gotten too warm.

If you use a CGM, try not to react to it too often. You might be tempted to give another dose of insulin too soon, before the first one finishes working, which is known as stacking insulin this can cause low blood sugar .

How Do I Prevent Hyperglycemia

  • Exercise to help lower blood sugar. Work with your healthcare provider to make a daily activity plan.
  • Follow your meal plan if you have one. Learn how carbohydrates impact your blood sugar, and work with your diabetes care team to find the best meal plan for you.
  • Maintain a healthy weight.
  • Limit drinking alcohol. Alcohol can raise blood sugar levels, but can also cause dangerously low blood sugar levels. Work with your provider to determine how much is safe to drink.

Diabetic Hyperglycemic Hyperosmolar Syndrome

Diabetic hyperglycemic hyperosmolar syndrome, or HHS, is a complication from very high blood sugars in people with type 2 diabetes.

It doesnt occur in people with type 1 diabetes, who experience a different complication called diabetic ketoacidosis when blood sugar levels are dangerously high.

HHS is a condition of:

  • Extremely high blood sugar level
  • Extreme lack of water
  • In many cases, decreased alertness or consciousness

Normally, the kidneys help to filter out extra blood glucose by increasing the amount of urine removed from the body. This is why one of the symptoms of diabetes is increased urination.

When excess urine is removed from the body, it can lead to dehydration. When the body is dehydrated, it cant make enough urine to flush out the extra sugar.

This leads to hyperosmolality, where the blood has higher concentrations of glucose , salt, and other substances. This can cause water to be drawn away from other sources of fluid, such as the brain, which is why it can cause an altered level of consciousness.

Microvascular Damage Of Eyes Kidneys Toes Etc

How To Recognize High Blood Sugar

Microvascular damage is defined as damage to small blood vessels, and its a common consequence of high blood sugar. Evidence confirms that acute hyperglycemia causes microvascular damage and leads to poor functional recovery, especially in patients who have sustained myocardial infarction.

For example, numbers show that more than 661,000 Americans have kidney failure, but high blood pressure and diabetes are the most common risk factors for this serious health problem. Almost half of the patients with chronic kidney disease have diabetes. This isnt such a surprise if we bear in mind that poor glycemic control is associated with microvascular disease development.

High blood sugar damages nerves and interferes with their ability to send signals, which causes diabetic neuropathy. Damage of this kind usually affects eyes, kidneys, toes, and other parts of a patients body.

What Is Diabetic Ketoacidosis

If you think you may have low blood sugar, check it even if you dont have symptoms.

When too many ketones are produced too fast, they can build up in your body and cause diabetic ketoacidosis, or DKA. DKA is very serious and can cause a coma or even death. Common symptoms of DKA include:

  • Fast, deep breathing.
  • Nausea and vomiting.

If you think you may have DKA, test your urine for ketones. Follow the test kit directions, checking the color of the test strip against the color chart in the kit to see your ketone level. If your ketones are high, . DKA requires treatment in a hospital.

DKA happens most in people with type 1 diabetes and is sometimes the first sign of type 1 in people who havent yet been diagnosed. People with type 2 diabetes can also develop DKA, but its less common.

Moderate To Severe High Blood Sugar

You may have moderate to severe symptoms if your blood sugar levels are consistently high. These symptoms include:

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

People with type 1 diabetes and some people with type 2 diabetes produce little or no insulin. These people may also have:

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

If your blood sugar levels continue to rise, you may:

  • Become confused and sluggish.
  • Pass out if your blood sugar levels are very high.

High Blood Glucose: Hyperglycemia

Hyperglycemia means that you have too much blood glucose. It happens when your blood glucose level is around 200 mg/dL or higher. Hyperglycemia can happen if you miss taking your diabetes medications, eat too much or do not get enough exercise. Sometimes, the medications you take for other problems cause high blood glucose.

Symptoms of hyperglycemia include:

  • Having blurry vision
  • Having to urinate often

If you have these symptoms, check your blood glucose right away. If its too high, follow these steps:

  • Check your blood glucose every four hours. If your level does not go down after two checks or your symptoms get worse, call a member of your diabetes team.
  • Drink water or other sugar-free liquids, such as diet soda or Crystal Light.
  • You may need to take an extra dose of insulin. Your diabetes educator talks with you more about this.

What Is Considered A High Blood Sugar Level

How to bring down high blood sugar levels (hyperglycemia)

If you just received a diabetes diagnosis, you may be wondering what blood sugar levels mean and how you should be creating goals based off of your blood glucose tracking. One of the most important things for you to know is what blood sugar levels are and when theyre considered to be high. Learning what steps to take if you find your levels are too high will help you stay safe.

Because diabetes is such an individual condition, the best first step is to consult your doctor about what is a healthy range for your blood sugar. Once youve gotten advice from your medical expert, you can begin to modify your lifestyle and continue to do additional research to improve your health and benefit your diabetes management journey. Before researching online, its important to remember that blood sugar levels are an individual, personal reaction to many factors, and can vary while still being within an acceptable range. Generalized numbers are often not a 100% accurate measure of personal health and there may be other factors that are affecting your blood sugar, resulting in confusing numbers when you check.

Make sure that you carefully follow the instructions your doctor has created for you. Diabetes can have negative effects if not managed properly. By understanding healthy blood sugar ranges, you can take steps to reduce or avoid added diabetes complications, and better understand what changes in blood sugar may be reflecting about your bodys health.

What Causes Low Blood Sugar

Low blood sugar has many causes, including missing a meal, taking too much insulin, taking other diabetes medicines, exercising more than normal, and drinking alcohol. Blood sugar below 70 mg/dL is considered low.

Signs of low blood sugar are different for everyone. Common symptoms include:

Know what your individual symptoms are so you can catch low blood sugar early and treat it. If you think you may have low blood sugar, check it even if you dont have symptoms. Low blood sugar can be dangerous and should be treated as soon as possible.

Problems Caused By High Blood Sugar

It’s not usually a serious problem if your blood sugar is sometimes slightly high for a short time.

But high blood sugar can cause serious problems if it stays high for a long time or gets to a very high level.

It can lead to:

If you have high blood sugar, your doctor or care team may ask you to test your blood or pee to check for ketones. A high level of ketones is a sign of diabetic ketoacidosis.

Treatment For High Blood Sugar Levels

For those with high blood sugar levels, it is vital to keep track of your blood sugars at home on a daily basis. This can be done with a glucose meter. These test monitors are often provided to diabetic patients so that they can manage their blood sugar levels at home everyday. They are available to purchase online if you are non-diabetic but wish to check on your levels regularly for safety.

Diabetic patients can be prescribed medications to help with insulin levels when their blood sugar is high. Those with type 1 diabetes will be prescribed medication which needs to be taken several times daily. This type of diabetes has no cure but can be managed with the right medication.

Those with type 2 diabetes or gestational diabetes can treat their high blood sugar with a change in diet or exercise. A healthier balanced diet is usually advised and sometimes, insulin medication is also prescribed if the blood sugar level becomes abnormally higher than the high reading for diabetic patients.

Postoperative And Rehabilitation Care

14 Signs Showing That Your Blood Sugar Is Very High â Info You Should Know

Hyperglycemia is common postoperatively. High blood sugars postoperatively are associated with higher perioperative complications so the target blood sugars should be kept around 140-180 mg/dL. Multiple teams take care of postoperative patients during their hospital stay, thereby needing a multidisciplinary team to create and follow protocols to treat hyperglycemia and decrease perioperative and postoperative complications.

What Is Hyperglycemia

Hyperglycemia, or high blood glucose, occurs when there is too much sugar in the blood. This happens when your body has too little insulin , or if your body can’t use insulin properly. The condition is most often linked with diabetes.

Hyperglycemia is blood glucose greater than 125 mg/dL while fasting .

  • A person has impaired glucose tolerance, or pre-diabetes, with a fasting blood glucose of 100 mg/dL to 125 mg/dL.
  • A person has hyperglycemia if their blood glucose is greater than 180 mg/dL one to two hours after eating.

If you have hyperglycemia and its untreated for long periods of time, you can damage your nerves, blood vessels, tissues and organs. Damage to blood vessels can increase your risk of heart attack and stroke, and nerve damage may also lead to eye damage, kidney damage and non-healing wounds.
