It will also shed light on what food is boosting your sugar too highand thus should be avoided. “You should consult your health-care provider to develop a plan that works for you,” says Donna Rice, immediate past president of the American Association of Diabetes Educators, who notes that the frequency and time of day you test will depend on how controlled your blood glucose is.

Hyperglycemia: What Happens If Your Blood Sugar Is Too High For Too Long

Hyperglycemia means high blood sugar, and is one of the defining characteristics of diabetes, and means that the body does not make or use insulin properly. The body needs glucose to function properly, as the cells rely on it for energy. Glucose comes from the foods that are eaten. Fruit, milk, potatoes, bread, and rice are all carbohydrates and the biggest sources of glucose in a normal diet. The carbohydrates are broken down into glucose and then transported to the cells through the bloodstream.

How Do I Treat Hyperglycemia

You can often lower your;blood sugar level;by exercising. However, if your blood sugar is above 240;mg/dl, check your urine for ketones.;If you have ketones, do not exercise.

Exercising when ketones are present may make your blood sugar level go even higher. You’ll need to work with your doctor to find the safest way for you to lower your blood sugar level.


Cutting down on the amount of food you eat might also help. Work with your;dietitian;to make changes in your meal plan. If exercise and changes in your diet don’t work, your doctor may change the amount of your medication or insulin or possibly the timing of when you take it.

Blood sugar control is crucial when youre living with type 2 diabetes. Dips and spikes can not only make you feel cranky and sluggish, but they can also wreak havoc on your personal health.

The most serious effects of blood sugar swings are a higher risk for diabetes-related health complications such as stroke, heart disease, and nerve damage .

For the record, the;American Diabetes Association notes that you have diabetes if one of the following applies to you:


  • Your blood glucose after fasting is 126 milligrams per deciliter or higher.
  • Your blood glucose two hours after eating a meal is 200 mg/dl or higher.
  • Your hemoglobin A1C is 6.5 or higher.

The tricky part is that with type 2 diabetes you may not feel it when blood sugar levels are too high, according to the ADA. It feels different for everyone. Not everyone will have the same symptoms, and some individuals will have no symptoms at all, says;Lori Zanini, RD, CDE, a Los Angelesbased former spokesperson for the Academy of Nutrition and Dietetics.

Blood Sugar Spike Causes

What To Do When Blood Sugar Is High

Blood sugar levels fluctuate all day long. When you eat food, particularly those foods that are high in carbohydrates like bread, potatoes, or pasta, your blood sugar will immediately begin to rise.

If your blood sugar is consistently high, you need to talk to your doctor about improving your diabetes management. Blood sugar rises when:


  • youre not taking enough insulin
  • your insulin isnt lasting as long as you think it is
  • youre not taking your oral diabetes medication
  • your medication dosage needs adjusting
  • youre using expired insulin
  • youre not following your nutritional plan
  • you have an illness or infection
  • youre using certain medications, like steroids
  • youre under physical stress, such as an injury or surgery
  • youre under emotional stress, such as trouble at work or home or with money problems

If your blood sugar is usually well-controlled, but youre experiencing unexplained blood sugar spikes, there might be a more acute cause.

Try keeping a record of all the food and drinks you consume. Check your blood sugar levels according to your doctors recommendations.

Its common to record your blood sugar reading first thing in the morning, before youve eaten, and then again two hours after eating. Even a few days of recorded information can help you and your doctor discover whats causing your blood sugar spikes.

Common culprits include:

Normal Blood Sugar Levels In Children

Younger than 6 years old mg/dL

Bedtime;100-140

Adults who are 20 years or older will have blood sugar levels that range between less than 100-180 mg/dL over the course of a day. When you wake up in the morning, your fasting blood sugar should be at its lowest because you havent consumed food for about eight hours. If youre an adult and struggling with glucose control, your healthcare provider can help you develop a treatment plan to manage your blood sugar better.;;;

Blood glucose levels outside the ranges listed above are categorized as either high or low blood sugar. Blood sugar levels are considered high if theyre over 130 mg/dL before a meal or 180 mg/dL within one to two hours after a meal. Many people wont start to experience symptoms from high blood sugar until their levels are at 250 mg/dL or higher. The highest blood sugar level thats considered safe will depend on the person and whether they have diabetes, but will typically be between 160 to 240 mg/dL.;

What Are The Signs & Symptoms Of High Blood Sugar Levels

Signs of high blood sugar levels include:

  • Peeing a lot: The kidneys respond by flushing out the extra glucose in urine. People with high blood sugar need to pee more often and in larger amounts.
  • Drinking a lot: Someone losing so much fluid from peeing that often can get very thirsty.
  • Losing weight even though your appetite has stayed the same: If there isn’t enough insulin to help the body use glucose, the body breaks down muscle and stored fat instead in an attempt to provide fuel to hungry cells.
  • Feeling tired: Because the body can’t use glucose for energy properly, a person may feel unusually tired.

Headaches And Difficulty Concentrating

Acute hyperglycemia can cause headaches and difficulty concentrating in a fashion similar to polyphagia in which starving cells send out hunger signals because they cant access the glucose circulating in the blood.

Your brain is the biggest glucose hog around. If you dont believe it, consider that while the brain represents about 2 percent of your body weight, it devours fully 25 percent of the glucose you consume. And when brain cells have difficulty getting the fuel they need, they function poorly. This can cause problems with thinking, reasoning, and remembering, difficulty staying focused on tasks, and headaches.

Chronic high blood glucose can also lead to headaches, but by a different route. These headaches are often related to various types of nerve damage. Examples include occipital neuropathy, or damage to the optic nerve from elevated glucose levels, and a variety of diabetic mononeuropathies, which can affect specific cranial nerves, peripheral nerves, or nerve roots all of which can lead to headaches of varying intensities.

    If you have diabetes and your blood sugar is too high, your cells cant function correctly, and youll start to feel uncomfortably sick.


    The cells in your body need glucose, more commonly known as sugar, to survive and function. Our diets contain many sources of glucose, but it cant reach our bodies cells without the help of insulin, a hormone secreted by the pancreas.

    Insulin is responsible for transporting glucose to your cells. When your body doesnt have enough insulin or it is not active enough, both symptoms of diabetes, the sugar remains in the blood without reaching cells. Thats why;diabetes;and high blood sugar often go hand in hand.

    What Causes High Blood Sugar?

    Sugar accumulates in the blood either when there is not enough insulin to transport it or when the insulin that is available is not active.

    Type 1 diabetes;patients are incapable of making the insulin necessary to transport glucose to the cells.


    Type 2 diabetes;patients are insulin resistant. They often, but not always, have the insulin required by the body, but the insulin is ineffective.

    Patients with diabetes are more prone to high blood sugar levels if they:

    • Miss taking diabetes medication or insulin
