Long term drinking may result in permanent brain damage, serious mental disorders and addiction to alcohol.

Steady drinking over many years leads to permanent changes in the brain. One of the permanent effects of alcohol on the brain is to reduce the amount of brain tissue and to increase the size of the ventricles instead. Another way in which alcoholic drinks affect the brain is through depriving it of food substances such as vitamins. This is because heavy drinkers often neglect their diet, which can lead to vitamin deficiencies. Thiamine, one of the 'B' vitamins is most commonly missing from the diet and can lead to serious mental disturbance.

Some of the most serious effects on the body of drinking alcoholic drinks are caused by damage done to the liver by alcohol. If alcohol is frequently in the blood in large amounts, it causes the liver cells to die and prevents the liver from working efficiently. This disease is called Cirrhosis. In the case of a generally healthy person, if alcohol is taken infrequently or only in moderate amounts, any damaged liver tissue has time to repair itself.

Chromic heavy drinking may cause alcoholic hepatitis (inflammation and destruction of the liver cells) and then cirrhosis (irreversible lesions, scarring and destruction of liver cells). Impairs the liver's ability to remove yellow pigment and skin appears yellow (Jaundice). Liver damage causes fluid to build in extremities (Edema).
