bloedsuikers

Bloedsuikers refers to the concentration of glucose in the blood, a key indicator of metabolic health. Humans acquire glucose primarily through the digestion of carbohydrates, and the hormone insulin, secreted by the pancreas, facilitates its uptake into cells. Glucose is the main energy source for organs such as the brain and heart; therefore tight regulation of blood sugar levels is essential for normal physiological function.

In a healthy individual, fasting blood glucose usually falls between 70 and 100 milligrams per deciliter (mg/dL). Postprandial, or after a meal, values may rise to 140 mg/dL or less, depending on the carbohydrate load and timing of measurement. These reference limits are determined using standardized laboratory methods and may vary slightly between countries and between laboratory equipment.

Elevated bloedsuikers over time can indicate impaired glucose tolerance and are a hallmark of type 2 diabetes mellitus. Conversely, abnormally low glucose—hypoglycemia—can arise from excessive insulin therapy, a slow adrenal response, or other endocrine disorders. Both conditions can lead to acute symptoms such as sweating, shakiness, and confusion, and if left untreated may progress to severe neurological or cardiovascular complications.

Screening tools include fasting plasma glucose tests, oral glucose tolerance tests, and glycated hemoglobin (HbA1c) measurements, which reflect average blood glucose over the previous three months. Management of abnormal bloedsuikers typically involves dietary modifications, regular physical activity, pharmacotherapy with agents such as metformin or insulin, and periodic monitoring of glucose excursions.

Early detection and consistent management of blood sugar levels can reduce the risk of long-term complications such as retinopathy, nephropathy, and cardiovascular disease. Health professionals encourage individuals with risk factors—overweight, sedentary lifestyle, or family history of diabetes—to undergo routine testing and adopt lifestyle changes to maintain euglycemia.
