Alcohol-related health conditions

The relationship between alcohol use and some health conditions is complex.

For example, drinking a small amount of alcohol may be beneficial in preventing heart disease in older adults but drinking a lot of alcohol can also damage the heart. For other health conditions, alcohol is the single cause of the condition, such as alcoholic cirrhosis of the liver, FASD and alcohol-induced pancreatitis. For many other health conditions, alcohol is one cause, amongst others, of the condition eg, cancers and pneumonia.9 Overall, alcohol is a cause of more 60 different health conditions and, for almost all conditions, heavier alcohol use means higher risk of disease or injury.9,27

Chronic alcohol use - Potential complications

For some people, alcohol is a regular or occasional drink enjoyed at social occasions that causes no apparent harm. However, even moderate alcohol use carries some risks, as alcohol causes breast cancer even at low doses, can damage the developing fetus before a woman even knows she is pregnant and can lead to addiction and dependence in any individual.

When drunk regularly over time and/or drunk in a pattern of heavy single drinking sessions, alcohol can cause a variety of health conditions. These include cancers and other conditions such as alcoholic liver disease, which can range from reversible to permanent liver damage due to alcohol. The risks of alcohol-related cancers and other health conditions caused by alcohol are greatest in those who are dependent on alcohol or drink heavily, and the risks increase with the average amount of alcohol drunk. The table below lists some of the conditions and complications of chronic and/or heavy episodic alcohol use.9
