What is the likely outcome of hypoglycemia if untreated?

Hypoglycemia, which is a condition characterized by abnormally low blood sugar levels, can lead to various symptoms and outcomes if not treated promptly. One of the significant dangers of untreated hypoglycemia is the risk of loss of consciousness. This occurs because the brain relies heavily on glucose as its primary energy source; when glucose levels drop, neuronal function becomes impaired. Severe depletion of glucose can disrupt the brain's ability to function properly, leading to confusion, disorientation, seizures, and ultimately, loss of consciousness.

In contrast, hyperactivity is generally associated with higher glucose levels or excessive amounts of sugar intake, while improved metabolic function and weight gain do not align with the effects of hypoglycemia. Improved metabolic function would indicate that the body's use of glucose is enhanced, which is not a consequence of low blood sugar. Weight gain typically results from an energy surplus rather than a deficiency like hypoglycemia. Thus, loss of consciousness is a critical and dangerous outcome of untreated hypoglycemia, reinforcing the importance of recognizing and addressing low blood sugar levels promptly.
