When Is Blood Sugar Too High


It Is Dangerous To Walk Around With High Blood Sugar For Too Long

10 Alarming Signs Your Blood Sugar Is Too High

Your blood sugar level starts to rise when your body produces less or no insuline. Normally, your body produces insuline automatically, for example, when youve had a meal with a lot of carbs. The amount of carbs makes your blood sugar levels go up, but insuline makes those levels go down again. You can imagine that this process does not work the way it should when your body does not produce enough insuline. Blood sugar levels that are too high are dangerous, which is why we present you with ten signs to help your recognise it.

Do you often have complaints like these?

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.

Make Some Small Changes

You might try to get more exercise, or limit carbs at your next meal, but don’t go crazy. “One blood sugar that’s high doesn’t indicate a need for major changesthat should only be done on a pattern,” says Rice, such as “continuing highs despite following a doctor’s instructions.” If a pattern continues for two to three days or more, then you might want to let your health-care provider know.

You Feel Tiredness And Fatigue Constantly

Fatigue and extreme tiredness are symptoms of uncontrolled blood sugar, the ADA says. Simply put, when your body is not processing insulin properly or it doesnt have sufficient amounts of insulin, the sugar is staying in our blood rather than getting into our cells to be used for energy, Zanini says. Also, frequent urination can lead to dehydration, which Bandukwala identifies as another contributing factor to fatigue.

9 SIGNS YOUR BLOOD SUGAR IS TOO HIGH

Your body releases stress hormones when you are sick, which can cause hyperglycemia. Keep taking your insulin and other diabetes medications, even if you are throwing up. If you have ketones and your blood sugar is above 240 mg/dL, call your doctor. They might also want you to call if:

  • You have diarrhea that lasts more than 6 hours
  • You are throwing up
  • You have a high fever or trouble breathing
  • You feel very sleepy or confused

Continue checking your blood sugar levels and keep track of the results.

Excessive Urination Or Polyuria

When the blood glucose levels are too high in your body, the body tries to get rid of the same through urine. This results in the increasing need of using the washroom more frequently to urinate. When you have a urine output which is more than around 2.5 liters per day, you are said to have the problem of excessive urination. When you have extremely high levels of blood glucose, you can even urinate as much as 15 liters of urine in one day. This problem of polyuria, in turn, gives rise to a host of other complications in the human body.

What Is Considered A High Blood Sugar Level

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.

How Can You Tell If Your Blood Sugar Is High

How to bring down high blood sugar levels (hyperglycemia)

If you dont have a glucometer , there are some physical symptoms that indicate high blood glucose. Usually if blood sugar is very high, the kidney is trying to eliminate all that sugar and in order to eliminate all that sugar, we need water to get rid of things, says Dr. Wright. That causes increased urination. You might also experience thirst as your body gets more dehydrated from the loss of fluid. Other patients, they describe that they might feel dizzy or sometimes they feel like their hands are tingly and that’s when they know that the blood sugars are high, adds Dr. Wright. Unfortunately, diabetes affects nearly every body part so symptoms can vary greatly. Other signs could be fatigue, just really not having the energy that you would expect you should have at that time, says Dr. Hong. And then more severely, things like nausea and vomiting or even abdominal pain can be signs of hyperglycemia.

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 .

You Develop Sores That Tend To Heal More Slowly Than Usual

Cuts, scrapes, bruises, and other wounds heal more slowly in the presence of uncontrolled blood sugar, according to the National Institute of Diabetes and Digestive and Kidney Diseases. Diabetes causes nerve damage and affects circulation, especially in the lower legs and feet, which can delay healing because there isnt enough blood flow to the area. Even minor wounds are more prone to infections, which can become very serious and even result in amputations of the foot. You may notice drainage seeping onto your socks or an unpleasant smell if you develop a foot ulcer, notes the American Podiatric Medical Association.

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.

When To Contact Your Healthcare Provider

9 Signs Your Blood Sugar Is Too High

Hyperglycemia can turn into a medical emergency like DKA and HHS that requires immediate intervention by your practitioner or a local emergency department. If you have two blood sugar readings of 300 mg/dL or more, or have blood sugar above your target range for more than a week, seek immediate medical help.

Signs of hyperglycemia include:

  • Ketones in your urine
  • Stomach pain, nausea, or vomiting
  • Shortness of breath

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.

High Blood Glucose: Diabetic Ketoacidosis

If your insulin level is too low, your blood glucose could become so high that it is unsafe. You might develop a serious problem called diabetic ketoacidosis . This usually happens in people with Type 1 diabetes and those with glucose levels over 500.

If you have DKA, chemicals called ketones start to make a lot of acid in your body. The acid and high blood glucose can make you very sick. You might also become dehydrated . You can prevent DKA by carefully giving yourself the correct insulin dose every day.


If you have any of the following symptoms of DKA, get to your local emergency department right away. You need to be treated with insulin and fluids that are given to you through an IV :

  • Blurry vision
  • Dry mouth, eyes or skin
  • Fast breathing
  • Feeling very weak or tired
  • Fruity-smelling breath
  • Stomach pain, nausea or vomiting

What Is High Blood Sugar

Elevated blood sugar levels are known as hyperglycemia. Blood sugar levels are measured using a small sample of blood that is tested in a lab. Blood sugar can also be tested using at home devices such as a handheld glucometer. Levels that indicate hyperglycemia are indicative of prediabetes and both type 1 and type 2 diabetes.

Normal ranges of blood sugar will vary depending on the test being done. In general, a normal fasting glucose level will be between 70-100 mg/dL. After a meal, these levels are expected to rise slightly around 1 to 2 hours after the beginning of a meal, but should be less than 180 ml/dL.

Maintaining healthy blood sugar levels is important not only for metabolic health, but heart health too. Over time, high blood sugar can damage blood vessels and the nerves that control your heart. People with diabetes are also more likely to have other conditions that raise the risk for heart disease:


  • High blood pressure increases the force of blood through your arteries and can damage artery walls. Having both high blood pressure and diabetes can greatly increase your risk for heart disease.
  • Too much LDL cholesterol in your bloodstream can form plaque on damaged artery walls.

Hyperosmolar Hyperglycemic Nonketotic Syndrome

Symptoms of When Your Blood Sugar is Too High

This mostly affects elderly people. As glucose builds up in your blood, your body tries to get rid of it through your urine.

At first, you pee a lot. Over time, you pee less, but when you do, itâs very dark. This condition can lead to dehydration, coma, and death.

Get medical help right away if you have any of these warning signs:

  • Blood sugar level over 600 mg/dL
  • Extreme thirst that may later go away
  • Warm, dry skin that doesnât sweat
  • Fever over 101 F
  • Weakness on one side of your body
  • Vision loss
  • Hallucinations

You can avoid many of these problems by keeping your blood sugar under control. Follow your doctorâs advice about diet and exercise, take your medicine, keep up with your doctor visits, and check your levels often.
