The term "overdose" refers to an emergency involving __________.

The term "overdose" specifically refers to a situation where an individual consumes an excessive amount of a substance, leading to harmful or potentially fatal effects. This commonly applies to drugs or alcohol, which can depress the central nervous system or cause toxic reactions in the body when taken in amounts greater than what the body can safely metabolize.

In cases of overdose, the corresponding symptoms can range from confusion, difficulty breathing, and loss of consciousness to more severe manifestations such as seizures or even death. This medical emergency requires immediate intervention to reverse the effects, often involving the administration of specific antidotes or supportive care.

While excessive exercise, physical injuries, and severe allergic reactions can pose serious health risks, they are categorized differently and do not fit the definition of an overdose as it pertains specifically to substance consumption. This distinction helps responders effectively assess situations and apply appropriate treatment protocols in emergency scenarios.
