The most common short-term effect of alcohol abuse is a hangover. This term describes a group of symptoms experienced by a person after heavy consumption of alcohol. These symptoms often include nausea, fatigue, thirst, headache, diarrhea, and sensitivity to light and noise. The severity of the hangover depends on several factors, including the amount of alcohol consumed, the level of hydration in the body at the time of alcohol consumption, and disease.
However, a hangover is only one of the many short-term effects of alcohol abuse. Other problems that can develop include:

Different effects of alcohol contribute to increased likelihood of aggressive behaviour. Effects of alcohol on the brain can reduce the anxiety about the consequences of one’s actions. They also impair thinking and problem solving ability in situations of conflict and result in overly emotional responses. Other effects of alcohol on behaviour include a resolute focus on the present ( alcohol myopia ) and a need to affirm personal power, at least for men.
So if alcohol is a natural product, why do we need to be concerned about drinking it? When people drink, alcohol is absorbed into their bloodstream. From there, it affects the central nervous system (the brain and spinal cord), which controls virtually all body functions. Alcohol is a depressant, which means it slows the function of the central nervous system. That's why drinking small amounts of alcohol reduces anxiety. Alcohol actually blocks some of the messages trying to get to the brain. This alters your perceptions, your emotions, and even your movements, vision, and hearing. More alcohol causes greater changes in the brain, resulting in intoxication. People who have overused alcohol may stagger, lose their coordination, and slur their speech. They will probably be confused and disoriented. Intoxication can make people very friendly and talkative or very aggressive and angry. Reaction times are slowed dramatically. People who are intoxicated may think they're moving properly, when they're not. They may act totally out of character. The following is a summary of the effects that alcohol has on your body.
