Health conditions - chronic alcohol use

Potential complications of chronic alcohol use

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]
