Acute Alcohol Intoxication Hangover

Overview, Causes, & Risk Factors

A hangover is the set of symptoms caused by excessive alcohol intake.

What is going on in the body?

Someone who has a hangover has usually consumed a large amount of alcohol in the previous 24 hours. Most times, the alcohol also dehydrates the person. Some sleep deprivation is common. Alcohol intoxication can cause a simple lack of sleep or a disturbance in proper sleep patterns. Hangovers can cause a wide range of symptoms.

What are the causes and risks of the disease?

Drinking alcohol is nearly always the cause of a hangover. Some alcoholic drinks are more likely to lead to hangovers. These include cognac, wine, champagne, brandy, and some whiskeys. Drinking on an empty stomach, having a low percentage of body fat, or being small in size, can also make a hangover more likely. There is a significant risk of death from alcohol poisoning if individuals drink too much too fast or ignore the symptoms of a hangover and continue drinking.
