If you or a loved one struggles with an alcohol problem, you might be curious about the causes of alcohol addiction.
Alcohol use disorder (AUD), or alcohol addiction, occurs when a person cannot control his or her drinking. Someone with alcoholism is preoccupied with alcohol and continues to use it despite the problems that occur after drinking. Alcohol withdrawal symptoms usually occur when not drinking. Over time, someone with alcohol use disorder must drink alcohol more to achieve the same effects.
Binge drinking is considered an alcohol use disorder. Many young adults especially may experience peer pressure to binge drink.
However, most people who binge drink are not alcohol dependent. People who binge drink are more likely to develop a dependency on alcohol.
A person’s addiction to alcohol can range from mild to severe, but mild disorders can escalate and cause long-term problems too.
Everyone is different, and many believe that certain people tend to have a stronger reaction to drinking alcohol than others. As a result, this makes them more susceptible to developing an addiction. Specific causes of alcohol addiction and substance use disorders include genetic, psychological, social, and environmental factors in a person’s life.
It’s also important to note that drinking changes a person’s brain function. Excessive alcohol consumption and substance abuse can have long-lasting effects on neurotransmitters in the brain, decreasing their effectiveness or even mimicking them.
Alcohol also destroys brain cells and contracts brain tissue. Even if someone was not likely to develop an alcohol use disorder initially, heavy drinking could change the brain to make addiction more likely.
Several risk factors are potential causes of alcohol addiction, including:
A person’s social life or environment alone is unlikely to cause an alcohol abuse disorder, but it can increase a person’s odds of developing a problem if he or she is already at risk.
People already at risk for alcohol use disorder are more likely to become alcoholics if they have a partner or close friends who drink regularly. Receiving the message, especially at a young age, that it is acceptable to drink too much also plays a role in a person’s likelihood to develop a problem.
Rehab facilities are open and accepting new patients
The symptoms of alcohol abuse are based on the behaviors and physical outcomes that develop as a result of alcohol addiction. People with alcoholism may engage in the following behaviors:
People with alcoholism may also experience the following physical symptoms and side effects:
Sometimes it can be challenging to draw the line between safe alcohol consumption and the misuse of alcohol. If you answer yes to some of the following questions, you may misuse alcohol:
Your doctor or healthcare provider can diagnose alcoholism. They will perform a physical exam and ask questions about your problem drinking habits.
Your doctor may ask if you:
Your doctor may also use a questionnaire that evaluates alcohol use disorder to help diagnose your condition. Usually, a diagnosis of alcohol use disorder does not involve any other type of diagnostic test.
There is a chance your doctor may order blood work to check your liver function if you display signs or symptoms of liver disease. Alcohol use disorder can lead to severe and lasting damage to your liver.
Your liver removes toxins from your blood. When you consume too much alcohol, your liver has a tougher time filtering the alcohol and other toxins from your bloodstream. This can result in liver disease and other complications.
Parents, peers, and role models influence young people and these peoples’ attitudes toward alcohol will increase or decrease someone’s risk of having an alcohol problem later in life.
Experiencing trauma increases a person’s risk of developing alcohol use disorder. This is especially true when the trauma involves violence or assault, including childhood physical and sexual abuse or rape. Those who experienced other types of traumatic events such as floods, fires, natural disasters, accidents, or witnessing harm to someone else also have a higher risk of developing a problem with alcohol.
According to a study conducted by researchers at Washington University School of Medicine in St. Louis and the Midwest Alcoholism Research Center (MARC), women with post-traumatic stress disorder (PTSD) have an elevated rate of alcohol dependence.
Women who have experienced traumatic events are far more likely to develop an alcohol addiction. Some estimates show double the risk for these women.
A different study led by the same research team found genetic factors likely play a role, and women with a family history of either PTSD or alcohol use disorder have a higher risk for developing both disorders.
You can prevent alcohol use disorder by limiting or reducing your alcohol intake. Women should not consume more than one drink per drink. Men should not drink more than two drinks per day.
If you are concerned, see your doctor to discuss addiction treatment options to stop drinking and to receive medical advice. Inpatient or outpatient treatment programs can help immensely. It would help if you also considered participating in support groups such as local AA meetings or attending self-help programs.
The National Institute on Alcohol Abuse and Alcoholism (NIAA) also has an online tool called NIAAA Alcohol Treatment Navigator, which allows you to find the right treatment.
There is evidence that undergoing bariatric surgery could lead to an increased risk of developing alcohol use disorder or relapsing if you’ve previously dealt with AUD.
According to a study published in the Journal of the American Medical Association, the risk is highest about two years after surgery. There was speculation based on anecdotal evidence of a connection between alcohol abuse and weight loss surgery.
Researchers found those undergoing Roux-en-Y procedures more than doubled their risk for alcohol problems. The Roux-en-Y procedure involves creating a small pouch from the stomach and connecting the pouch directly to the small intestine. After the procedure, food goes into the pouch and then directly into the small intestine, bypassing most of the stomach and part of the small intestine.
This study looked at 2000 obese people in the immediate, one- and two-year period after undergoing surgery. The percentage of people with alcohol abuse disorder before surgery remained the same immediately and one year after undergoing bariatric surgery.
Although, in the second year, the percentage of people abusing alcohol increased. The study revealed that 20.8 percent of RYGB patients went on to develop alcohol use disorder symptoms within 5 years of having the procedure. By contrast, only 11.3 percent of the laparoscopic gastric banding patients developed similar problems.
Researchers point out this does not prove the procedure is one of the causes of alcohol addiction. Still, because of how this specific procedure affects how the body metabolizes alcohol and allows it to reach the small intestine faster, there is likely a link. Another possibility is that RYGB increases tolerance by altering the genetic expression of the hormones that deal with reward circuits in the brain.
Researchers also found that instances of alcohol abuse disorder were higher among younger male study participants who were:
Researchers point out this information makes it easier to recommend the best possible weight -loss procedure for a specific patient. It also provides directives for after-care following a procedure.
