When a person drinks alcohol, the alcohol is absorbed by the stomach, enters the bloodstream, and goes to all the tissues. The effects of alcohol are dependent on a variety of factors, including a person’s size, weight, age and sex, as well as the amount of food and alcohol consumed. The disinhibiting effect of alcohol is one of the main reasons it is used in so many social situations. Other effects of moderate alcohol intake include dizziness and increased socialbility; the immediate effects of a larger amount of alcohol include slurred speech, disturbed sleep, nausea and vomiting. Alcohol, even at low doses, significantly impairs the judgment and coordination required to drive a car safely. Low to moderate doses of alcohol can also increase the incidence of a variety of aggressive acts, including domestic violence and child abuse. Hangovers are another effect after large amounts of alcohol are consumed; a hangover consists of headaches, nausea, thirst, dizziness and fatigue.
