What Is Considered High Blood Sugar
Blood sugar levels are considered high in people with diabetes once theyre more than the recommended 120 mg/dL, however, having a blood sugar of 145 mg/dL usually wont cause any problems .
For most people, high blood sugars become symptomatic once the blood sugar level reaches between 180-200 mg/dL.
Blood sugars above 200 mg/dL need to be treated immediately with insulin , and any blood sugar over 250 mg/dL requires that you do a urine test for ketones, to make sure youre not spiraling into diabetic ketoacidosis .
This is when the bodys blood turns acidic due to prolonged, dangerously high blood sugar levels and ketones in the blood. This can be fatal if not treated immediately.
This can occur when one is sick or battling an infection, due to a pump infusion site failure or even if you forgot to take your insulin for a few days.
Unfortunately, about 25% of newly diagnosed people with type 1 diabetes are diagnosed when they are already in DKA.
If you are experiencing a blood sugar higher than 250 mg/dL along with moderate to high ketones for several hours and cannot get your blood sugar down, contact your doctor immediately and seek emergency medical attention.
People with diabetes are at heightened risk of falling into a diabetic coma from high blood sugar once their blood sugar levels reach 600 mg/dL or higher.
This is a true medical emergency, is extremely dangerous, and can be life-threatening. If you are in this situation, you should call 911.

- An electrocardiogram to measure your hearts electrical activity. Your heartbeat is the result of an electrical impulse traveling through your heart.

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

What Causes Complications Associated With Diabetes

High sugar levels in your blood over a long period of time can seriously damage your blood vessels. If your blood vessels arent working properly, blood cant travel to the parts of your body it needs to. This means your nerves wont work properly either and means you lose feeling in parts of your body. Once youve damaged the blood vessels and nerves in one part of your body, youre more likely to develop similar problems in other parts of your body. So if your feet are damaged, serious heart problems can follow.
We know that the higher your HbA1c level, the more youre at risk of developing complications. HbA1c is is glycated haemoglobin. This is made when glucose, which we call sugar, sticks to your blood cells and builds up in your blood. It’s measured by a blood test that shows your average blood sugar levels over the last three months. A high HbA1c means you have too much sugar in your blood.
Even a slightly high HbA1c increases your risk.
But its not just about blood sugars. High blood pressure, smoking and a lot of fat in your blood can all damage your blood vessels and put you even more at risk.

Complications From Chronic High Blood Sugar
Over time, high blood sugar damages the arteries and vessels of the body. When these vessels are damaged, complications can occur.
- Heart disease: people with diabetes are two to four times more likely to die from cardiovascular disease than those without diabetes. People with diabetes are also more likely to have high blood pressure, which is another risk factor for heart disease.
- Stroke: Diabetes increases the risk of stroke, as well as increases mortality when a stroke occurs.
- Kidney disease and failure: High blood sugar damages the kidneys and can lead to kidney disease. About one in four people with diabetes have kidney disease.
- Poor wound healing leading to amputations: High blood sugar inhibits proper wound healing. Diabetes is thought to be the leading cause of leg amputations worldwide.
- Neuropathy: Damage to the nerves, which can cause painful symptoms like numb and tingling legs and feet, as well as delayed stomach emptying from damage to the stomachs nerves.
- Retinopathy and blindness: Damage to the nerves in the eyes is called retinopathy, which can lead to blindness if not treated.

Causes Of High Blood Sugar
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.
Diabetes And Healthy Eating
If you have diabetes its important to include a wide variety of nutritious and healthy foods in your diet, and to avoid snacking on sugary foods.
Enjoy a variety of foods from each food group be sure to include foods high in fibre and low in fat and reduce your salt intake. Its helpful to consult with a dietitian to review your current eating plan and provide a guide about food choices and food quantities.

Danger Zone High Blood Sugar
Ongoing high blood sugar is a warning sign that your body is in the danger zone. Just like the displays, gauges, and lights on the dashboard of a vehicle, high blood sugar is a warning indicator you need to have your body checked out now for potential life-altering and life-threatening conditions. When our blood sugar is measured we receive a measurement for that point in time. This reading gives us markers and reference points linked to how our lifestyle choices impact our blood sugar and overall health. Our blood sugar is determined by how well our body can balance many factors. We must convert the nutrition we consume to glucose in our blood and tissue. It also depends on how well the pancreas can produce and process insulin, which plays a key role in dealing with sugar uptake and utilization. When our blood sugar is too high it means the body is unable to maintain the optimal balance needed for fuel usage, health, and wellness.
How To Prevent Hyperglycaemia And Lower Your Blood Sugar Levels

Testing your blood sugar levels regularly can help you spot the signs of hyperglycaemia. But there are some steps you can take to either prevent a hyper from happening or to bring down your blood sugar levels.
You can start by making sure you are aware of your carbohydrate portions and how they may be affecting your blood sugar levels after eating. Carb countingis one of the ways you can manage this. Avoid foods that have a high glycemic index and choose low GI foods that can help manage your blood sugar levels more effectively. Increase the fibre in your diet. This can help slow down carbohydrate digestion, which can help limit the rise in your blood sugars.
Try to maintain a healthy weight as this promotes regular blood sugar levels in the body. Be as active as possible, regular exercise can help your body process more of the sugar.
Remember to take your insulin and other diabetes medication, and always take them correctly. Continue to take your diabetes medication even if you are ill and not eating.
Concentrate on your emotional wellbeing, get a quality nights sleep and find ways to manage your stress. Stress can cause hormones to be released, which keep your blood sugar levels high.
If your blood sugar levels continue to be high, or youre unsure of what to do, contact your doctor for further guidance.
