Alcohol-related health problems can be severe and long-lasting; some may even be fatal.
What happens if I drink excessively over a long period?
Excessive and prolonged alcohol consumption can lead to numerous health issues, affecting various organs and systems in the body (1). The severity and likelihood of these problems depend on the frequency, quantity, and duration of drinking.
Alcoholic liver disease: A major concern
Liver damage from excessive drinking is one of the most significant risks. Alcoholic liver disease can progress to cirrhosis, liver cancer, or liver failure (2). In the US, the Centers for Disease Control and Prevention (CDC) reported that alcohol use contributed to about 50,000 deaths from liver disease in 2019 (3).
Cardiovascular risks and heart problems
Heavy drinking can lead to high blood pressure, heart attacks, strokes, arrhythmias, and sudden cardiac death (4). Regular excessive consumption can also damage the heart muscle and lead to cardiomyopathy.
Neurological damage and mental health issues
Excessive drinking can cause brain damage, cognitive impairment, and increased risk of depression, anxiety, and mental health disorders (5). Wernicke-Korsakoff syndrome, a serious condition caused by thiamine (vitamin B1) deficiency, often associated with alcohol use, can lead to significant memory problems and difficulties with problem-solving.
Gastrointestinal issues and cancer risk
Alcohol consumption has been linked to stomach ulcers, mouth and throat cancers, esophageal cancer, and an increased risk of colorectal cancer (6). The relationship between alcohol and cancer is complex and can be influenced by individual factors, such as overall diet and lifestyle.
Immune system effects and infections
Heavy drinking can weaken the immune system, making it more challenging to fight off infections (7). This can increase the risk of pneumonia, tuberculosis, and other infections, especially in people with compromised immune systems.
Other long-term risks and health complications
Excessive alcohol consumption has also been linked to:
- Osteoporosis and increased risk of fractures
- Sleep disorders and difficulties
- Reproductive issues and infertility
- Increased risk of certain cancers, such as breast and colon cancer
- Pancreatitis, a painful and potentially life-threatening condition
