Low Blood Sugar (Hypoglycemic Condition)
In a healthy individual, glucose homeostasis ensures that blood sugar levels remain within a physiological range, averaging between 70 and 99 milligrams per deciliter in a fasting state and not exceeding 140 mg/dL postprandially. These parameters guarantee an adequate supply of glucose to cells—the fundamental energy substrate essential for sustaining normal metabolic functions. As per the 2018 guidelines issued by the Polish Diabetes Association, **hypoglycemia** is formally defined as a reduction in blood glucose concentration below the threshold of 70 mg/dL (equivalent to 3.9 mmol/L), irrespective of whether clinical manifestations are present. This condition serves as a critical alert, necessitating immediate corrective action, such as the ingestion of rapidly absorbable carbohydrates or adjustment of hypoglycemic medication dosages, to preclude potentially severe or life-endangering complications.
