Insulin hypoglycemia is a disorder of carbohydrate metabolism in which blood glucose levels drop to below normal levels without damaging blood cells or other tissues. Typically, blood sugar levels do not fall below 3.3-5.5 mmol/l. This depends on many factors, including weight, age, gender and physical activity. When a patient's sugar level is below normal, hypoglycemia develops. This condition causes symptoms of varying intensity - weakness, sweating, palpitations, hunger, loss of consciousness. When the first symptoms occur, you should consult a doctor who will select the appropriate treatment.
