Symptoms of hypoglycemia are twofold: symptoms of autonomic nervous system hypoglycemia and symptoms of cerebral neuronal hypoglycemia, and there is no significant difference in symptoms between men and women. Autonomic hypoglycemic symptoms: These include tremors, palpitations, and anxiety, as well as sweating, hunger, and sensory abnormalities, which are largely caused by sympathetic activation rather than adrenal medulla activation. They disappear on their own with sugar supplementation. Symptoms of neuronal hypoglycemia in the brain: these include cognitive impairment, behavioral changes, psychomotor abnormalities, and seizures and coma at even lower blood glucose concentrations. Although severe, prolonged hypoglycemia can lead to brain death in unnoticed diabetics, the vast majority of hypoglycemic episodes can be reversed when glucose levels rise to normal. The rare fatal episodes are usually thought to be the result of hypoglycemia-induced cardiac arrhythmias. Signs of hypoglycemia: Pallor and sweating are common signs of hypoglycemia. Heart rate and systolic blood pressure rise, but not to any great extent, and autonomic hypoglycemia is often observed, with occasional transient neurologic deficits. Permanent neurologic damage is seen in patients with prolonged recurrent hypoglycemia and in patients in whom a single episode of severe hypoglycemia fails to correct in time. In female patients, long-term chronic hypoglycemia has the potential to also lead to gynecological problems such as menstrual irregularities, but it is uncommon, and hypoglycemia due to gestational diabetes may affect the fetus, but hyperglycemia is still the main hazard. Therefore, the symptoms of hypoglycemia include both symptoms of hypoglycemia in the autonomic nervous system and hypoglycemia in the neurons of the brain, and there is no significant difference between men and women.
