What is a potential consequence of untreated insulin shock?

Untreated insulin shock, also known as severe hypoglycemia, can lead to significant neurological consequences due to the brain's reliance on glucose for energy. When insulin levels are excessively high relative to glucose levels, the body experiences a drastic decrease in blood sugar (hypoglycemia). If this condition is not promptly addressed, it can result in seizures and loss of consciousness.

Seizures occur because neurons, which are very sensitive to changes in glucose, start to malfunction when deprived of their primary energy source. Prolonged hypoglycemia can also lead to more severe outcomes, such as brain damage, if the brain remains starved of glucose for an extended period. Loss of consciousness occurs as the brain's function diminishes critically due to inadequate glucose supply, leading to a state where the individual cannot be aroused.

In contrast, the other options such as hyperglycemia, hyperactivity, and weight gain are not directly related to untreated insulin shock. Hyperglycemia occurs when there is an excess of glucose in the bloodstream, which is the opposite of what happens during insulin shock. Hyperactivity is typically associated with elevated blood sugar levels rather than low. Finally, weight gain is not a consequence of hypoglycemic episodes but rather a potential effect of long-term
