Hyperglycaemia (high blood sugar) (2024)

FAQs

Hyperglycaemia (high blood sugar)? ›

Hyperglycemia occurs when the level of blood glucose gets too high. Hyperglycemia can affect people of any age and can cause a range of symptoms, including excessive thirst, hunger, fatigue, and/or an urge to urinate larger amounts than usual.

Hyperglycemia is blood glucose greater than 125 mg/dL while fasting and greater than 180 mg/dL 2 hours postprandial. A patient has impaired glucose tolerance, or pre-diabetes, with a fasting plasma glucose of 100 mg/dL to 125 mg/dL.

High blood sugar (hyperglycaemia) is where the level of sugar in your blood is too high. It mainly affects people with diabetes and can be serious if not treated. People with diabetes can also have blood sugar that's too low. This is called low blood sugar (hypoglycaemia).

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.

The quickest way to lower your blood sugar is to take fast-acting insulin. Exercising is another fast, effective way. However, in severe cases, you should go to the hospital. High blood sugar levels are known as hyperglycemia or high blood glucose.

A high blood sugar level of more than 240 with or without symptoms requires calling the doctor immediately. Healthcare providers will administer ER treatment to reduce the level and symptoms.

You can experience classic high blood sugar symptoms such as increased urination or increased thirst or hunger, while weight loss and blurry vision may seem less obvious. A treatment plan change may be necessary to get your blood sugars back in a healthy range if you have diabetes and experience high blood sugar signs.

What is dangerously high blood sugar for type 2 diabetes? ›

If your blood sugar level goes above 600 milligrams per deciliter (mg/dL), or 33.3 millimoles per liter (mmol/L), the condition is called diabetic hyperosmolar syndrome. When blood sugar is very high, the extra sugar passes from the blood into the urine.

You have non-diabetic hyperglycaemia (sometimes also called pre-diabetes, impaired glucose tolerance or impaired fasting glycaemia) which means your blood glucose is raised beyond the normal range but it is not so high that you have diabetes. However, you are at risk of developing type 2 diabetes.

If you have diabetes, you'll need to check your blood sugar, also called glucose, to know if it's too high, too low, or meets your goal. 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.

Drinking water is an excellent way to stay hydrated without consuming sugar. Green tea, cow's milk, and fermented milk (kefir) could also help you manage your blood sugar responses. Coffee also contains compounds that may help regulate blood sugar, but confirming this requires more research.

Water is the best all-round drink. If your family likes flavoured waters, make your own by adding a squeeze of lemon or lime, or strawberries.

A fasting blood sugar level less than 100 mg/dL (5.6 mmol/L) is normal. A fasting blood sugar level from 100 to 125 mg/dL (5.6 to 6.9 mmol/L) is considered prediabetes. If it's 126 mg/dL (7 mmol/L) or higher on two separate tests, you have diabetes. Glucose tolerance test.

“Millimoles per liter” (mmol/l) is the unit that blood sugar is measured in. It describes the amount of sugar molecules per liter. If someone has readings over 7.8 mmol/l (140 mg/dl), they are considered to have high blood sugar (hyperglycemia).

High blood sugar—or hyperglycemia—occurs when an individual's glucose levels rise to 240 mg/dL or higher. If untreated, hyperglycemia may lead to ketoacidosis, a condition commonly known as diabetic coma. Ketones are waste products made when the body breaks down fats due to insufficient insulin.
