Effects of Alcohol On Health
See also: Alcohol and sex, Blood alcohol content, Alcohol intoxication, Long-term effects of alcohol, and Short-term effects of alcoholShort-term effects of alcohol consumption include intoxication and dehydration. Long-term effects of alcohol include changes in the metabolism of the liver and brain and alcoholism (addiction to alcohol).
Alcohol intoxication affects the brain, causing slurred speech, clumsiness, and delayed reflexes. Alcohol stimulates insulin production, which speeds up glucose metabolism and can result in low blood sugar, causing irritability and (for diabetics) possible death. Severe alcohol poisoning can be fatal.
A blood alcohol content of .45% in test animals results in a median lethal dose of LD50. This means that .45% is the concentration of blood alcohol that is fatal in 50% of the test subjects. That is about six times the level of ordinary intoxication (0.08%), but vomiting or unconsciousness may occur much sooner in people who have a low tolerance for alcohol. The high tolerance of chronic heavy drinkers may allow some of them to remain conscious at levels above .40%, although serious health dangers are incurred at this level.
Alcohol also limits the production of vasopressin (ADH) from the hypothalamus and the secretion of this hormone from the posterior pituitary gland. This is what causes severe dehydration when large amounts of alcohol are drunk. It also causes a high concentration of water in the urine and vomit and the intense thirst that goes along with a hangover.
Stress, hangovers and oral contraceptive pill may increase the desire for alcohol because these things will lower the level of testosterone and alcohol will acutely elevate it. Tobacco has the same effect of increasing the craving for alcohol.

Famous quotes containing the words effects of, effects, alcohol and/or health:
“The hippie is the scion of surplus value. The dropout can only claim sanctity in a society which offers something to be dropped out of—career, ambition, conspicuous consumption. The effects of hippie sanctimony can only be felt in the context of others who plunder his lifestyle for what they find good or profitable, a process known as rip-off by the hippie, who will not see how savagely he has pillaged intricate and demanding civilizations for his own parodic lifestyle.”
—Germaine Greer (b. 1939)
“The machines that are first invented to perform any particular movement are always the most complex, and succeeding artists generally discover that, with fewer wheels, with fewer principles of motion, than had originally been employed, the same effects may be more easily produced. The first systems, in the same manner, are always the most complex.”
—Adam Smith (1723–1790)
“The sacrifice to Legba was completed; the Master of the Crossroads had taken the loas’ mysterious routes back to his native Guinea.
Meanwhile, the feast continued. The peasants were forgetting their misery: dance and alcohol numbed them, carrying away their shipwrecked conscience in the unreal and shady regions where the savage madness of the African gods lay waiting.”
—Jacques Roumain (1907–1945)
“Even though I had let them choose their own socks since babyhood, I was only beginning to learn to trust their adult judgment.. . . I had a sensation very much like the moment in an airplane when you realize that even if you stop holding the plane up by gripping the arms of your seat until your knuckles show white, the plane will stay up by itself. . . . To detach myself from my children . . . I had to achieve a condition which might be called loving objectivity.”
—Anonymous Parent of Adult Children. Ourselves and Our Children, by Boston Women’s Health Book Collective, ch. 5 (1978)
