Alcoholism and Fetal Alcohol Syndrome
Alcoholism and Fetal Alcohol Syndrome
Alcoholism is a serious, chronic and potentially fatal condition in which a person has an uncontrollable urge to drink alcoholic beverages. Alcoholism can be seen in all the rich and the poor, the young and the old, and males and females. It has been estimated that 75 percent of alcoholics are male and 25 percent are female. Biological, psychological, social, and cultural factors all seem to play a role in the development of alcoholism. Children with a biological parent who is an alcoholic are more likely to become alcoholics than are children who do not have an alcoholic parent. Peer pressure, the social acceptability of drinking, and a desire to escape from emotional stress and anxiety can all set the stage for a person’s descent into alcohol addiction.
Alcohol is a depressant that acts as a numbing agent on the central nervous system. Some adults can drink alcohol-containing beverages in moderate amounts without experiencing significant side effects. The ability to tolerate alcohol differs from person to person. Alcohol affects women more easily because women lack a stomach enzyme present in men that breaks down some of the alcohol before it reaches the intestines. Thus, if a man and a woman both drink a glass of wine, more alcohol will enter the woman’s bloodstream than the man’s. Alcohol affects every cell in the body, especially those of the liver, heart, and brain. Excessive use can lead to permanent brain damage, heart disease, and cirrhosis of the liver. Alcohol provides calories but no nourishment to the body. It also robs the body of vitamins and minerals necessary to maintain proper cell function.
When alcohol is ingested, it is absorbed from the intestines directly into the bloodstream, where it is carried to all organs of the body. Most of the alcohol consumed is passed to the liver, which detoxifies the alcohol by first converting it to a chemical called acetaldehyde. Acetaldehyde is then changed to acetic acid, which in turn is converted to carbon dioxide and water or to fat, according to the body’s energy needs. If alcohol is consumed faster than the liver can process it, a sufficient amount is carried by the blood to the brain, affecting mental functioning. In alcoholics, the conversion of acetaldehyde to acetic acid is slow to occur because of impaired liver function from previous alcohol abuse. Acetaldehyde thus accumulates in other organs of the body, causing symptoms such as staggering gait, shaking hands, blinding headaches, and hallucinations. High levels of acetaldehyde can result in pain, which can be eased temporarily by further drinking.
In the first stage of alcoholism, a person may drink heavily and remain functional. Withdrawal symptoms (The set of physical and psychological symptoms that occur when alcohol intake is stopped suddenly) following excessive use are absent other than the standard hangover that follows excessive drinking. The body’s cells adapt to large quantities of alcohol and use the energy it provides to continue functioning. However, alcohol eventually begins to attack cell structures, erode cell membranes, and alter cellular chemical balances. Fatty deposits accumulate in the liver cells, causing the “fatty liver” common in heavy drinkers.
No definite signpost marks the border between the early and middle stages of alcoholism, and the change may take years. Eventually, however, the alcoholic drinks to counteract the symptoms of alcoholism, not to get high or to be able to function better. Deterioration of cells in all parts of the body produces symptoms such as severe headaches, trembling, chills, and nausea when the level of alcohol in the blood falls. As cellular metabolism becomes more and more dependent upon alcohol, an alcohol-dependent person shows signs of alcohol withdrawal delirium when intake is stopped abruptly. He may experience loss of appetite and uncontrollable bodily shaking, become frightened and shrink into a corner, or become dangerous as he lashes out to protect himself from an imaginary attack. The person may also manipulate his hands as if playing a game of cards, throwing dice, or whittling. These symptoms require immediate medical attention as they can be precursors to a heart attack, stroke, or respiratory failure.
Fetal alcohol syndrome (FAS) is a group of birth defects found in some children whose mothers drank alcohol during pregnancy. Since a fetus or unborn baby receives its nourishment directly from the blood stream of its mother, alcohol easily enters the fetus’s body. The level of alcohol in a fetus’s blood is the same as that of its mother’s within just a few short minutes after the mother has begun drinking. The effects of FAS range from mild to severe, depending on the amount and frequency of alcohol consumed by a mother during her pregnancy. The weight and height of newborns suffering from FAS is lower than average. They also have
