Alcohol’s Effects on Health National Institute on Alcohol Abuse and Alcoholism NIAAA

The long-term effects of alcohol on the body and brain explain the condition’s accepted medical standing as a chronic brain disease. Alcohol can impact various parts of the body, including the brain, heart, liver, and pancreas, as well as essential body systems like the immune and digestive systems. Alcohol use can increase the risk of cardiovascular problems, cognitive decline, liver disease, mental health conditions, and more. Research has demonstrated that long-term heavy drinking weakens the heart muscle, causing cardiomyopathy. Alcohol misuse can also lead to high blood pressure, an irregular heartbeat (arrhythmia), or increased heart rate. Chronic, heavy drinking raises the risk for ischemic heart disease (heart problems caused by narrowed arteries) and myocardial infarction (heart attack).

The brain is highly vulnerable to the damaging effects of alcohol, which disrupts communication between brain cells. Excessive or chronic alcohol use can lead to a steady decline in cognitive function, causing memory problems, difficulty learning new information, mood changes, and behavior changes. Continuous, heavy, habitual drinking takes a toll on the human body. As a result of their self-destructive behavior, alcoholics may suffer dire long-term alcohol effects that produce irreversible consequences. As the body adapts to the presence of the drug, dependency and addiction can result.

This leads to a chronic inflammation of the liver and eventually alcoholic liver disease. The short-term effects of alcohol consumption range from a decrease in anxiety and motor skills at lower doses to unconsciousness, anterograde amnesia, and central nervous system depression at higher doses. Cell membranes are highly permeable to alcohol, so once alcohol is in the bloodstream it can diffuse into nearly every cell in the body. Alcohol addiction is a disease characterized by a strong craving for alcohol, and continued use despite a negative impact on health, interpersonal relationships, and ability to work. If the person stops drinking, they will experience withdrawal symptoms. Alcohol’s impact on the functioning of the brain ranges from mild and anxiolytic disinhibitory effects, motor incoordination, sedation, emesis, amnesia, hypnosis and ultimately unconsciousness 4.
