Know your risks
Brain
Alcohol is known to kill brain cells and thereby hinders the chemical messengers that control your mood, perception, and behaviour. It also impairs your balance, thinking, memory, and ability to learn.
Liver
When alcohol reaches your liver, it produces a toxic enzyme (acetaldehyde) that can damage liver cells and cause permanent scarring. Alcohol is also a diuretic, and since your liver needs water to function properly, excessive drinking can lead to severe dehydration.
Heart
Stomach
Immune System
Getting sick all of the time? Drinking too much weakens your immune system, slowing down your body’s ability to fight off infections and leaving you more vulnerable to serious illnesses such as pneumonia. It can also increase your risk of developing certain cancers, including mouth, throat, liver, and breast cancer.
