What makes a person go into a coma?

A person can enter a coma due to various factors that disrupt normal brain function. Common causes include traumatic brain injuries, strokes, seizures, drug overdoses, infections affecting the brain (like encephalitis or meningitis), and metabolic imbalances (such as severe hypoglycemia or liver failure). These conditions can impair consciousness by affecting the brain's ability to maintain awareness and response to stimuli. The severity and duration of the coma depend on the underlying cause and the extent of brain damage.
