Alcohol Use Disorder (AUD) is a medical condition that makes it difficult for a person to stop or control their drinking, even when it leads to problems with health, safety, relationships, or responsibilities at work, home, or school.
AUD includes a range of drinking behaviors, from excessive use to alcohol dependence, and can vary in severity. It is considered a brain disorder, and long-term alcohol misuse can cause changes in brain function that increase the likelihood of a return to use after someone has tried to cut back or quit. The good news is that treatment can help. Behavioral therapies, mutual support groups, and medications are available to support people in reducing or stopping alcohol use and maintaining long-term recovery.
Common signs that alcohol may be becoming a problem include:

It’s difficult to predict who will develop Alcohol Use Disorder (AUD). Alcohol addiction is shaped by a mix of internal and external factors, and some people may be at greater risk than others.
Mental Health (Internal) – Stress, emotions, and coping styles can influence alcohol use. Conditions such as depression, anxiety, or PTSD increase the risk of drinking as a way to cope.
Genetics (Internal) – Family traits, brain chemistry, and overall health can make some people more vulnerable. Genetics, personality, personal choices, and psychological components all play a role. Long-term heavy drinking can also rewire brain circuits tied to reward, decision-making, and impulse control.
Environmental (External) – Home life, culture, and the availability of alcohol can shape drinking habits. Trauma, abuse, or ongoing stress can raise the likelihood of misuse.
Social (External) – Relationships, peer pressure, and community expectations may encourage or discourage drinking. Media portrayals that glamorize alcohol use can also contribute. Religion and cultural influences often affect attitudes toward alcohol as well.

Physical Health: Liver disease (e.g., cirrhosis), cardiovascular problems, pancreatitis, weakened immune system, digestive issues, and increased risk of several cancers.
Mental and Cognitive Health: Depression, anxiety, memory problems, difficulty with decision-making, and a higher risk of dementia or cognitive decline. Increased risk of suicide is also associated with long-term misuse.
Social Impact: Strained relationships, job loss, financial difficulties, and legal issues. These challenges often add stress that can worsen both physical and mental health.
Long-term effects may develop slowly and can be permanent, but treatment and recovery can reduce risks and improve health over time.
