Alcohol poisoning
Alcohol poisoning is a serious condition resulting from the rapid consumption of large amounts of alcohol, often associated with binge drinking—defined as having five or more drinks in a short period. This illness is primarily caused by ethanol, the alcohol found in beverages like beer, wine, and spirits, but can also result from methanol or isopropyl alcohol ingestion. Symptoms of alcohol poisoning include confusion, respiratory depression, irregular breathing, and even unconsciousness, which can be life-threatening.
Risk factors for alcohol poisoning include the speed of consumption, gender differences in alcohol metabolism, age (particularly among teenagers and young adults), body mass, overall health, food intake, and interactions with drugs. Diagnosis is typically determined by measuring blood alcohol content (BAC), with levels above 0.30% indicating severe poisoning. Treatment focuses on supportive care to help the body metabolize alcohol and may require interventions like oxygen support and intravenous fluids.
Prevention efforts emphasize education to reduce binge drinking and promote responsible alcohol consumption, especially among high-risk groups such as young men. Increasing awareness and fostering strong parental relationships can play a vital role in mitigating the risks associated with alcohol misuse.
Alcohol poisoning
ALSO KNOWN AS: Binge drinking; ethanol poisoning; isopropyl alcohol poisoning; methanol poisoning
DEFINITION: Alcohol poisoning is an illness caused by consuming a large amount of alcohol in a short time. It usually occurs after binge drinking, in which a person rapidly ingests five or more drinks in sequence. Alcohol poisoning can also result in coma and death. The amount of alcohol in the body is usually measured as blood alcohol content (BAC) and is expressed as the percentage of alcohol per liter of blood. Alcohol consumption is also measured by the number of drinks a person consumes.
Causes
Most alcohol poisoning cases are caused by ethanol (C2H5OH), which is a component of alcoholic beverages, namely beer, wine, and hard liquor. Ethanol has been produced by the fermentation of sugar since antiquity. Other alcohol poisoning cases are caused by methanol (CH3OH) or isopropyl alcohol (C3H8O). Methanol is primarily used to produce other chemicals; it is sometimes used as an automotive fuel. Isopropyl alcohol is a component of rubbing alcohol and is widely used as a solvent and a cleaning fluid.
All forms of alcohol are flammable and colorless, and all are readily available in the marketplace. Although the purchase of alcoholic beverages in the United States (US) is restricted to adults aged twenty-one years and older, minors often obtain the product through a third party, sometimes even their parents, without difficulty.
Risk Factors
Several factors increase the risk of becoming ill through alcohol poisoning. They include the following:
• Rate of drinking. The more rapidly a person consumes a given amount of alcohol, the more likely the risk of alcohol poisoning. One to two hours are required to metabolize one drink.
• Gender. Young men aged eighteen through twenty-five years are the most likely to experience alcohol poisoning; however, women are more susceptible to alcohol poisoning than men because they produce less of an enzyme that slows the release of alcohol from the stomach.
• Age. Teenagers and college-age youth are more likely to engage in binge drinking; however, the majority of these drinking-related deaths occur in persons aged thirty-five to fifty-four years. This older age group often does not metabolize alcohol as readily as younger persons and is more likely to have an underlying health problem that increases the risk.
• Body mass. A heavier person can drink more alcohol than a lighter person and still register the same BAC. For example, a 240-pound man who drinks two cocktails will have the same BAC as a 120-pound woman who consumes one cocktail.
• Overall health. Persons with kidney disease, liver disease, heart disease, or other health problems may metabolize alcohol more slowly. A person with diabetes, for example, who binge drinks might experience a dangerous drop in blood sugar level.
• Food consumption. A full stomach slows the absorption of alcohol, so drinking on an empty stomach increases the risk.
• Drug use. Prescription and over-the-counter drugs might increase the risk of alcohol poisoning. Ingestion of illegal substances, such as cocaine, methamphetamine, heroin, and marijuana, also increases the risk.
Symptoms
Alcohol poisoning symptoms include confusion, stupor, or unconsciousness; respiratory depression (slow breathing rate); irregular breathing (a gap of more than ten seconds between breaths); slow heart rate; low blood pressure; low body temperature (hypothermia); vomiting; seizures; and pale gray or blue skin.
Screening and Diagnosis
The BAC is a definitive test for alcohol poisoning. Persons with alcohol poisoning often have a BAC of 0.30 to 0.40 percent. By way of comparison, a person is considered to be driving under the influence in all US states if their BAC is 0.08 percent or higher. Other blood tests include those that check a person’s complete blood count (CBC) and those that check levels of glucose, urea, arterial pH (acid), and electrolytes.
Treatment and Therapy
Treatment consists of supportive measures until the body metabolizes the alcohol. This includes insertion of an airway (endotracheal tube) to prevent vomiting and aspiration of stomach contents into the lungs; close monitoring of vital signs (temperature, heart rate, and blood pressure); provisions of oxygen; medication to increase blood pressure and heart rate, if necessary; respiratory support, if necessary; maintenance of body temperature (blankets or warming devices); and administration of intravenous fluids to prevent dehydration. In such cases, glucose should be added if the person is hypoglycemic, that is, if the person has low blood sugar (also, thiamine is often added to reduce the risk of a seizure). Another form of treatment is hemodialysis (blood cleansing), which might be needed for a dangerously high BAC (more than 0.4 percent). Hemodialysis also is necessary if methanol or isopropyl alcohol has been ingested.
Prevention
The best prevention against binge drinking is education, especially for persons who participate in at-risk activities. Young men make up the group with the highest risk of alcohol poisoning. Often, young men have a sense of invincibility, and they may disregard helpful advice from any source. Peer pressure is probably the best deterrent; however, it also is a factor that can encourage binge drinking. Furthermore, children with a good parental relationship are less likely to drink to excess. As the twenty-first century progressed, there were signs that education was working, and there was a general societal shift in attitudes about the acceptability of problem drinking as instances of binge drinking and alcohol poisoning among teenagers, college students, and young adults all showed signs of decreasing.
