What Causes High Blood Sugar Levels
Managing diabetes is like a three-way balancing act because you have to watch:
All three need to be balanced. If any one of these is off, blood sugar levels can be too. In general, higher than normal blood glucose levels can be caused by:
- not taking your diabetes medicine when you’re supposed to or not taking the right amounts
- not following the meal plan
- not getting enough exercise
- having an illness, like the flu
- taking other kinds of medicines that affect how your diabetes medicines work
A single high blood sugar reading usually isn’t cause for alarm it happens to everyone with diabetes from time to time. But if you have high blood sugar levels a lot, let your parents and your diabetes health care team know. Insulin or meal plans may need adjusting, or you may have an equipment issue, like an insulin pump that isn’t working right. Whatever the case, make sure you get help so you can get your blood sugar levels back under control.

Irene Dunbar, 73, of Durham, N.C., woke up one morning recently to discover her blood sugar was at 119, which is high for her. “I had a cold and had had orange juice yesterday and I normally do not drink orange juice and I thought, ‘I better not do that,'” she said. When she gets a high blood sugar reading, she tries to remember if she had anything recentlylike breadthat she knows are triggers, and avoids them next time.

What Should My Blood Sugar Levels Be
Your blood sugar level changes depending on what you’ve eaten, whether you’ve exercised and other factors but we have some general guidelines to determine what levels are healthy.
For generally healthy individuals who haven’t eaten for eight hours or more, a normal blood sugar level is between 70-99 mg/dL. When you’ve eaten in the past two hours, it should be no higher than 140 mg/dL. To refresh your chemistry knowledge, that unit is milligrams per deciliter and it’s measuring the amount of glucose present in your blood.
Only a medical professional can diagnose diabetes or another issue with your blood sugar, so if you’re concerned about your blood sugar levels, check with a doctor.
High Blood Sugar Levels
Different targets have been set by various health organizations, but the American Diabetes Association has stated that fasting blood sugar should be between 80-130mg/dL, and two hours after a meal it should be less than 180mg/dL.
Some people experience high blood sugar in the mornings for several common reasons, like the Dawn Phenomenon. Fasting blood sugar is important to note, as it can give an idea of where your blood sugar naturally settles after a period without intervention.
Blood sugar rises after a meal, and then comes back down . Postprandial blood sugar is where it lands at the end of the trend line, which is generally two hours after the meal. If blood sugar is 180 mg/dL two hours after a meal, it could mean mis-calculating carb intake. Knowing the range your doctor has identified as a healthy rise is important in being aware of your bodys processes. Any number above your specific ranges is considered to be high.
Glucose is needed by your body, but when it rises too high over an extended period of time, it can have lasting detrimental effects. Its important that you regularly monitor your blood sugar levels so that youre aware of how your body is responding to your diabetes care plan.

If your blood glucose runs high for long periods of time, this can pose significant problems for your long-term increased risk of complications, such as eye disease, kidney disease, heart attacks and strokes and more. High blood glucose can pose health problems in the short-term as well. Your treatment plan may need adjustment if the blood glucose stays over 180 mg/dl for 3 days in a row. It is important to aim to keep your blood glucose under control and treat hyperglycemia when it occurs.

Hyperosmolar Hyperglycemic Nonketotic Syndrome : When Hyperglycemia Becomes Severe For People With Type 2 Diabetes
Hyperosmolar hyperglycemic nonketotic syndrome is very rare, but you should be aware of it and know how to handle it if it occurs. HHNS is when your blood glucose level goes way too highyou become extremely hyperglycemic. HHNS affects people with type 2 diabetes.
HHNS is most likely to occur when you’re sick, and elderly people are most likely to develop it. It starts when your blood glucose level starts to climb: when that happens, your body will try to get rid of all the excess glucose through frequent urination. That dehydrates your body, and you’ll become very thirsty.
Unfortunately, when you’re sick, it’s sometimes more difficult to rehydrate your body, as you know you should. For example, it might be difficult to keep fluids down. When you don’t rehydrate your body, the blood glucose level continues to climb, and it can eventually go so high that it could send you into a coma.
To avoid hyperosmolar hyperglycemic nonketotic syndrome, you should keep close watch on your blood glucose level when you’re sick .
Talk to your healthcare professional about having a sick-day plan to follow that will help you avoid HHNS.
You should also be able to quickly recognize the signs and symptoms of HHNS, which include:

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.
