High blood sugar, or hyperglycemia, primarily affects people who have diabetes. It occurs when your body doesn't produce enough insulin. It can also happen when your body is unable to absorb insulin properly or develops a resistance to insulin entirely. Hyperglycemia can also affect people who don't have diabetes.

Long term, this causes damage to organs, nerves, and blood vessels. Blood sugar spikes occur in people with diabetes because they're unable to use insulin effectively. Untreated high blood sugar can be dangerous, leading to a serious condition in diabetics called ketoacidosis.

Hyperglycemia is a defining characteristic of diabetes—when the blood glucose level is too high because the body isn't properly using or doesn't make the hormone insulin. Eating too many processed foods may cause your blood sugar to rise.

Nondiabetic hyperglycemia means your blood glucose (sugar) level is high even though you do not have diabetes. Hyperglycemia may happen suddenly during a major illness or injury. Instead, hyperglycemia may happen over a longer period of time and be caused by a chronic disease.

High blood sugar can cause problems all over the body. It can damage blood vessels and nerves. It can harm the eyes, kidneys, and heart. In early pregnancy, high blood sugar can lead to birth defects in a growing baby.

High blood sugar (hyperglycemia) affects people who have diabetes. Several factors can contribute to hyperglycemia in people with diabetes, including food and physical activity choices, illness, nondiabetes medications, or skipping or not taking enough glucose-lowering medication.

Diabetes is a chronic condition associated with abnormally high levels of sugar (glucose) in the blood. Insulin produced by the pancreas lowers blood glucose. Absence or insufficient production of insulin, or an inability of the body to properly use insulin causes diabetes.

'Hyperglycemia,' or high fasting blood sugar levels of between 100-150 mg/dL, might indicate pre-diabetes and levels above this range may indicate diabetes. A number of other conditions may cause hyperglycemia too, including: Acromegaly. Pancreatitis.

Over time, high blood glucose levels can damage the body's organs. Possible complications include damage to large (macrovascular) and small (microvascular) blood vessels, which can lead to heart attack, stroke, and problems with the kidneys, eyes, gums, feet and nerves.

A common symptom of high or low blood glucose is a headache. Headaches alone aren't harmful, but they can signal that your blood sugar is out of its target range. If you have frequent headaches, diabetes may be to blame. Find out if diabetes is the cause of your headache so you can take proper action.

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.

About type 1 diabetes. Type 1 diabetes causes the level of glucose (sugar) in your blood to become too high. It happens when your body can't produce enough of a hormone called insulin, which controls blood glucose. You need daily injections of insulin to keep your blood glucose levels under control.
