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.
Is There Anything Else I Should Know
If you are diabetic and your blood sugar is out of control, triglycerides may be very high.
Triglycerides change dramatically in response to meals, increasing as much as 5 to 10 times higher than fasting levels just a few hours after eating. Even fasting levels vary considerably day to day. Therefore, modest changes in fasting triglycerides measured on different days are not considered to be abnormal.
Certain drugs such as corticosteroids, protease inhibitors for HIV, beta blockers, and estrogens can increase blood triglyceride levels.
There is increasing interest in measuring triglycerides in people who have not fasted. The reason is that a non-fasting sample may be more representative of the âusualâ circulating level of triglyceride since most of the day blood lipid levels reflect post-meal levels rather than fasting levels. However, it is not yet certain how to interpret non-fasting levels for evaluating risk so, at present, there is no change in the current recommendations for fasting prior to tests for lipid levels.
What Are Normal Blood Sugar Levels
Normal blood sugar levels vary based on when you last ate. For example, if you just ate a meal, your blood sugar levels will be higher than if you haven’t eaten in a while.
The normal blood glucose range is 70-99 mg/dL before meals, and less than 140 mg/dL two hours after eating. If you are fasting , your blood sugar should be below 95 mg/dL.

How Do The Foods I Eat Affect My Blood Sugar Levels
The sugar in your blood comes from certain foods called carbohydrates, or “carbs.” Foods that are high in carbs include candy and sweets, sodas, breads, tortillas, and white rice. The more carbs you eat, the higher your blood sugar level will be.
Whether you have type 1 or type 2 diabetes, making the right food choices is an important way to keep your blood sugar at a healthy level. When you control your blood sugar, you lower your chance of having serious health problems from diabetes, such as vision loss and heart problems.
And if you have prediabetes or are at risk for diabetes, eating foods that keep your blood sugar levels healthy may help prevent type 2 diabetes later on.

Preventing Low Blood Sugar Levels
Here are some other tips to help you avoid low blood sugar levels:
- Eat all your meals and snacks on time and try not to skip any.
- Take the right amount of insulin.
- If you exercise longer or harder than usual, have an extra snack.
- Don’t take a hot bath or shower right after an insulin shot.
- Stick to your diabetes management plan.
- Check your blood sugar levels regularly, so you can tell if your blood sugars are running too low and your treatment plan needs adjustment.
- Carry something containing sugar with you at all times and take it right away if you have symptoms. Don’t wait to see if the symptoms will go away they may get worse!
Alcohol and drugs can cause major problems with your blood sugar levels, so avoiding them is another way to prevent diabetes problems. Drinking can be particularly dangerous even deadly for people with diabetes because it messes up the body’s ability to keep blood glucose in a normal range. This can cause a very rapid drop in blood glucose in people with diabetes. Drug or alcohol use is also dangerous because it may affect someone’s ability to sense low blood sugar levels.
Learning how to recognize the signs of low blood sugar levels and get them back to normal is an important part of caring for diabetes. Keeping track of your blood sugar levels and recording lows when they occur will help you and your diabetes health care team keep your blood sugar levels in a healthy range.
Correcting High Blood Sugar Levels With Insulin
If you take insulin, one way to reduce blood sugar is to inject insulin.
However, be careful as insulin can take 4 hours or longer to be fully absorbed, so you need to make sure you take into account how much insulin you may already have in your body that is yet to be absorbed by the blood. Insulin that is yet to be absorbed by the blood is called active insulin.
If you decide to correct with insulin, watch you dont over correct as this can lead to hypoglycemia and can be dangerous, particularly so before bed.

The Blood Sugar Level Regulation Mechanism
When you eat rice, bread, or any other typical food high in carbohydrates, it is digested by the stomach and small intestine, where it is absorbed into the blood as glucose. Figure 1 shows how it is absorbed into the body.
When glucose enters the bloodstream, insulin facilitates its uptake into the body’s cells. When an excess of glucose is ingested, insulin over secretion occurs. Insulin increases the biosynthesis of fat and suppresses its breakdown. Thus, it becomes easier for fat to accumulate in body tissues.
Blood sugar level will not drop if the sugar in the blood is not properly processed due to, for example, too little insulin being secreted, or resistance to the action of insulin. If blood sugar levels have not decreased several hours after eating on a regular basis, this indicates a susceptibility to diabetes. To avoid this and stay healthy, we should eat types of foods that will not cause a sudden, extreme rise in blood sugar levels.

Never Skip Eating Breakfast
Cameron Whitman/Stocksy
Weve all heard that breakfast is the days most important meal. This is especially true for those who have diabetes. I think eating breakfast is important, especially with potential risk for hypoglycemia and avoiding potential highs related to fasting for too long a period of time, Crandall Snyder says.
A high-protein breakfast has an edge over breakfasts that are high in carbohydrates, according to research from The University of Missouri-Columbia. In the research, women ages 18 to 55 consumed meals with similar calories, fat, and fiber contents but differing amounts of protein. Researchers monitored the amount of glucose and insulin in the participants blood for four hours after they ate breakfast. The best breakfasts contained 39 g of protein and led to lower post-meal glucose spikes than the meals with less protein, the researchers found.
Besides, eating breakfast may help overweight people with type 2 diabetes shed extra pounds. Of the participants in the National Weight Control Registry who maintained at least a 30-pound weight loss for at least one year, 78 percent said they eat breakfast daily.
What Causes Blood Sugar To Be High
Many things can cause high blood sugar , including being sick, being stressed, eating more than planned, and not giving yourself enough insulin. Over time, high blood sugar can lead to long-term, serious health problems. Symptoms of high blood sugar include:
- Feeling very tired.
- Having blurry vision.
- Needing to urinate more often.
If you get sick, your blood sugar can be hard to manage. You may not be able to eat or drink as much as usual, which can affect blood sugar levels. If youre ill and your blood sugar is 240 mg/dL or above, use an over-the-counter ketone test kit to check your urine for ketones and call your doctor if your ketones are high. High ketones can be an early sign of diabetic ketoacidosis, which is a medical emergency and needs to be treated immediately.

Easy Ways To Lower Blood Sugar Levels Naturally
High blood sugar, also known as hyperglycemia, is associated with diabetes and prediabetes. Prediabetes is when your blood sugar is high, but not high enough to be classified as diabetes.
Your body usually manages your blood sugar levels by producing insulin, a hormone that allows your cells to use the circulating sugar in your blood. As such, insulin is the most important regulator of blood sugar levels .
However, multiple factors can impair blood sugar management and lead to hyperglycemia.
Internal causes for high blood sugar include when your liver produces too much glucose, your body makes too little insulin, or your body cant effectively use insulin. The latter is known as insulin resistance (
2 ).
The Centers for Disease Control and Prevention reports that 13% of U.S. adults live with diabetes and that another 34.5% have prediabetes. This means that close to 50% of all U.S. adults have diabetes or prediabetes .
Blood sugar management is especially important for people with diabetes, as chronically high blood sugar levels can lead to limb and life threatening complications (
Increased insulin sensitivity means your cells can more effectively use the available sugar in your bloodstream.
Exercise also helps your muscles use blood sugar for energy and muscle contraction .
Whats more, researchers recommend doing so-called exercise snacks to lower blood sugar and prevent the damage that sitting all day can do .
What Is A High Blood Sugar Level Range
According to the American Diabetes Association , there are nearly 18 million diabetics in the United States, with nearly 25 percent of them unaware that they have the disease 1. Diabetes is a serious metabolic disorder that is caused by the pancreas not making enough insulin, or the body’s resistance to it. Insulin is a hormone that helps the body assimilate blood glucose to produce energy. When there is a problem metabolizing blood glucose, its concentrations rise in the blooda condition called hyperglycemia or high blood sugar.

The 10 Best Foods To Control Diabetes And Lower Blood Sugar
If you have diabetes, you know how difficult it can be to manage your diet and control your blood sugar levels. Certain foods cause massive spikes while others actually lower blood sugar, but many people go through years of trial and error before they find out what works for them. Luckily, thanks to years of scientific findings, weve been able to determine what foods are better than others. In this article, well discuss the 10 best foods to control diabetes and lower blood sugar.
To get the most out of your food, consider diabetic meal planning. Planning and preparing meals ahead of time will reduce the likelihood of snacking or unhealthy eating and will help you save time and energy throughout the week.
How Does Blood Sugar Level Work
With a lack of nutrients and food that contain glucose, the blood sugar level will begin to decline. This is known as hypoglycemia.
After blood sugar becomes low, the pancreas releases a peptide hormone called glucagon. When this happens, the glucose that is stored in the body for energy is instructed to release due to the liver. This causes the glucose to turn into glycogen, known as the glycogenesis process. This is what can help a body to regain energy as the readily stored glycogen, in the liver and muscles, will release into the body.
On the other hand, the blood sugar can also rise and become too high which is known as hyperglycemia.
When the body does not produce enough of the insulin hormone, blood sugar levels begin to increase. This is because glucose relies on the insulin hormone to help it absorb into the bloodstream. Usually, this occurs when the body cannot produce enough insulin, known as type 1 diabetes, or does not respond to insulin correctly, known as type 2 diabetes.
Eating too many processed foods can also cause your blood sugar level to rise. If there is not enough insulin present in the body, too much bad food can cause your blood sugar level to build up.
For those with a normal blood sugar level, this will be due to eating the right foods and your body being able to produce and respond to insulin.
