If it's not treated, hyperglycemia can become severe and cause serious health problems that require emergency care, including a diabetic coma. Hyperglycemia that lasts, even if it's not severe, can lead to health problems that affect the eyes, kidneys, nerves and heart.
Regularly having high blood sugar levels for long periods of time (over months or years) can result in permanent damage to parts of the body such as the eyes, nerves, kidneys and blood vessels. If you experience hyperglycaemia regularly, speak to your doctor or diabetes care team.
People With Diabetes Can Live Longer by Meeting Their Treatment Goals. Life expectancy can be increased by 3 years or in some cases as much as 10 years. At age 50, life expectancy- the number of years a person is expected to live- is 6 years shorter for people with type 2 diabetes than for people without it.
This can lead to blurred vision, difficulty concentrating, confused thinking, slurred speech, numbness, and drowsiness. If blood glucose stays low for too long, starving the brain of glucose, it may lead to seizures, coma, and very rarely death.
Symptoms of high blood sugar
feeling very thirsty. peeing a lot. feeling weak or tired. blurred vision.
Less than 140 mg/dL (7.8 mmol/L ) is normal. 140 to 199 mg/dL (7.8 mmol/L and 11.0 mmol/L ) is diagnosed as prediabetes. 200 mg/dL (11.1 mmol/L ) or higher after two hours suggests diabetes.
If your blood sugar level is slightly high for a short time, emergency treatment won't be necessary. But if it continues to rise you may need to act fast to avoid developing diabetic ketoacidosis (DKA). If your blood sugar level is 15 mmol/l or more, you should check your blood or urine for ketones.
If your blood sugar levels are consistently high (usually above 20 mmol/L in adults and above 14 mmol/L in children), you may have moderate to severe symptoms of high blood sugar.
A diabetic coma could happen when your blood sugar gets too high -- 600 milligrams per deciliter (mg/dL) or more -- causing you to become very dehydrated. It usually affects people with type 2 diabetes that isn't well-controlled. It's common among those who are elderly, chronically ill, and disabled.
First, the numbers. “Post-meal blood sugars of 140 mg/dl [milligrams per deciliter] and higher, and fasting blood sugars over 100 mg/dl [can] cause permanent organ damage and cause diabetes to progress,” Ruhl writes.
Impairment of glucose utilization subjected patients to be at higher risk for sudden cardiac death. Diabetes increases the risk of arterial disease and the likelihood of immediate cardiac arrest.
Indeed, myocardial infarction is the leading cause of death among individuals with diabetes mellitus.
If your blood sugar is higher than your goals over 3 days and you don't know why, check your urine for ketones. Then call your health care provider.
Emergency treatment for severe hyperglycemia
If you have signs and symptoms of diabetic ketoacidosis or hyperosmolar hyperglycemic state, you may be treated in the emergency room or admitted to the hospital.
Go to the ER or call 911 right away if you have symptoms of ketoacidosis like: nausea and vomiting. abdominal pain. deep, rapid breathing.
Hyperglycemia, the term for expressing high blood sugar, has been defined by the World Health Organisation as: Blood glucose levels greater than 7.0 mmol/L (126 mg/dl) when fasting. Blood glucose levels greater than 11.0 mmol/L (200 mg/dl) 2 hours after meals.
Recommended Blood Sugar Targets
Before meals, your blood sugar should be: From 90 to 130 mg/dL (5.0 to 7.2 mmol/L) for adults. From 90 to 130 mg/dL (5.0 to 7.2 mmol/L) for children, 13 to 19 years old.
If HbA1c is more than 48 mmol/mol or fasting blood glucose is more than 11 mmol/L, your blood sugar is high. For most people without diabetes, normal blood sugar levels are: between 4 and to 6 mmol/L before meals. less than 8 mmol/L two hours after eating.
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.
The AHA suggests a stricter added-sugar limit of no more than 100 calories per day (about 6 teaspoons or 24 grams) for most adult women and no more than 150 calories per day (about 9 teaspoons or 36 grams of sugar) for most men.
So people reduce their carb intake, go on a low carbohydrate diet, and focus on eating healthy fats and (in many cases) too much protein. But what this solution crucially fails to address is insulin resistance, which is the true cause of those high blood glucose numbers.
If your fasting blood glucose level is 7mmol/l or higher, this is likely to mean that you have diabetes. Diabetes is a long-term condition where the body is not able to control the amount of glucose in the blood. If your fasting blood glucose level is between 6.1mmol/l and 6.9mmols/l, you may have IFG.
Insulin therapy will often need to be started if the initial fasting plasma glucose is greater than 250 or the HbA1c is greater than 10%.
