How Alcohol Abuse Affects You

FASD can cause a range of neurodevelopmental and physical effects in the child after birth. Drinking alcohol is so common that people may not question how even one beer, cocktail, or glass of wine could impact their health. Alcohol is a part of cultural traditions all around the world…and it’s also a drug that chemically alters the body.

Alcohol addiction, or alcohol use disorder, is a complex and chronic brain disorder characterized by compulsive alcohol use, loss of control over drinking, and an intense craving for alcohol despite negative consequences. The National Institute on Alcohol Abuse and Alcoholism defines moderate drinking as two or fewer drinks in a day for men and one or less in a day for women. Excessive (binge) drinking is defined as four or more drinks on a single occasion for women and five or more drinks on a single occasion for men. According to the Centers for Disease Control and Prevention (CDC), 12 ounces of beer, 5 ounces of wine, and 1.5 ounces of 80-proof alcohol constitute one drink. In people assigned female at birth, consuming more than four drinks in one sitting is considered binge drinking. However, there may be legal, financial, or relational consequences for drinking heavily.

Finding treatment for alcohol use disorder

People with alcohol problems often drink alone and say they use alcohol to help them sleep or deal with stress. People who drink excessively may also engage in risky sexual behavior or drive when they should not. To avoid driving after consuming alcohol, it’s helpful to designate a nondrinking driver, or to use public transportation.

In the United States, over 84% of adults report drinking alcohol at least once in their lifetime. Every person has their own reasons for drinking or wanting to reduce their alcohol consumption. Depending on how much you have been drinking, your body may experience physical and psychological changes as you reduce your intake, known as withdrawal.

Neuropsychiatric Disorders

Health professionals counsel the person and family about the nature of addiction and help the person find positive alternatives to using alcohol. Health professionals also help the individual cope with any related problems, such as depression, job stress, legal consequences of drinking, or troubled personal relationships. Someone suffering from alcohol abuse can become more aggressive and his or her ability to function (hold a job or maintain relationships with friends and family) can seriously deteriorate. Heavy drinkers may experience tremors, panic attacks, confusion, hallucinations, and seizures.

The size of your body, whether or not you have eaten recently, and the rate at which you drink all affect how your body processes alcohol. A large person has more blood circulating in his or her body than a smaller person, so alcohol concentration in larger people rises more slowly than in a smaller person, even if they drink identical amounts of alcohol. Depending on the country, current guidelines (including those in the US) could allow levels of drinking high enough to shorten life expectancy.

Alcohol’s health effects: What you need to know

Treating alcohol abuse begins by helping the drinker understand that he or she has a problem and needs help. Once a drinker wants to stop, treatment can take place in an outpatient setting (such as regular appointments with a counselor) or in a hospital inpatient program (where the treatment is much more intensive). A person who needs help for alcohol addiction may be the last to realize he or she has a problem.

(A drink is defined as 5 ounces of how much did steve harwell drink wine, 12 ounces of beer, or 1½ ounces of 80-proof distilled spirits.) Moderate drinking appears to lower the risk of heart disease, stroke, and other circulatory diseases. There is evidence that a small amount of alcohol can boost levels of high-density lipoprotein (HDL), the beneficial cholesterol in your blood, as well as reduce the formation of plaque in blood vessels. Alcohol consumption is linked not only to unintentional but also to intentional injury. Both average volume of alcohol consumption and the level of drinking before the event have been shown to affect suicide risk (Borges and Loera 2010). There also is a clear link between alcohol consumption and aggression, including, but not limited to, homicides (Rehm et al. 2003b). The acute effects of alcohol consumption on injury risk are mediated by how regularly the individual drinks.

Irregular heavy drinking occasions, however, can nullify any protective effect. The authors concluded that the cardio-protective effect of moderate alcohol consumption disappears when light to moderate drinking is mixed with irregular heavy-drinking occasions. Alcohol use, especially excessive alcohol consumption, can harm your physical and mental health. From damaging vital organs to impairing brain function and jeopardizing relationships, the negative consequences of excessive alcohol use are far-reaching. Chronic alcohol use raises your risk for health problems, including heart disease, liver disease, cancer, and mental health disorders.
