Finally, the last symptom we will talk about is the most serious—loss of consciousness or fainting. Hypoglycaemia is when blood sugar can decline to a stage that is too low. No line comes at which you risk fainting; this is an individual apprehension. But really low sugar, like in severe hypoglycemia, can make you faint. As stated in this article, loss of consciousness is rarely the first sign of this condition.
Patients may notice altered consciousness and progression to loss of consciousness prior to this event. However, loss of consciousness is not always predictable, putting patients at risk of falls and injury.
Hypoglycemia symptoms are nothing to be snoozed on — the health repercussions are extremely severe. Loss of consciousness may not be permanent, but it may also be degenerative since hypoglycemia can lead to a coma. If blood glucose decreases too much, nerve cells become dysfunctional, which leads to impaired consciousness and a diabetic coma. So if you see someone collapse, you better ring for the ambulance too because it could be a hypoglycaemic patient.
