Short-term outcomes most likely experienced by underage drinkers do not include severe chronic diseases like kidney failure, cirrhosis of the liver, or heart disease, which typically develop over time due to chronic alcohol abuse. Instead, the most common short-term outcome underage drinkers experience is headaches, along with symptoms like vomiting and fatigue due to alcohol's immediate effects such as stomach irritation and central nervous system depression. Underage drinking more commonly leads to impaired judgment, risky behaviors, injury, and acute effects like headaches rather than the chronic diseases listed, which are long-term outcomes. Headaches are symptomatic of the body's immediate response to alcohol consumption in youth, whereas conditions like cirrhosis and heart disease develop with prolonged and heavy drinking over years or decades.
