Here are a few facts I found online:
*Why is an alcohol problem together with depression a particular worry?
Alcohol compromises judgement and makes people impulsive and likely to take risks. Alcohol also causes a loss of inhibition and increases aggressive behaviour and violent acts. Because increased alcohol consumption often occurs together with a depressed mood, this is a particular concern.
Depression can lead to thoughts of suicide.
The lack of self-control, compromised judgement and impulsivity from the alcohol can increase the chances of a person attempting suicide.
Generally, a much higher incidence of suicide, both completed and attempted, is associated with alcohol.
The common problems of depression and alcohol are frequently complicated by social problems. Alcohol can often lead to problems at work in the form of absenteeism, sickness and under performance. The loss of a job has a profound negative impact on a person’s financial status and family life.
Marital problems often arise because of an alcohol problem, although it may be difficult to say which started first.
Alcohol can also cause a large number of physical problems. Few, if any organs in the body are spared. Liver problems commonly arise from heavy alcohol intake and can take the form of jaundice (a yellow discolouration of the skin) resulting from hepatitis, cirrhosis of the liver or liver failure. Unchecked these will lead to death. Other common problems include:
stomach ulcers
anaemia
an irregular heartbeat
impotence.
Both alcohol intoxication and withdrawal have a damaging effect on the brain, and can cause:
loss of sensation in the arms or legs
loss of muscle power
profound memory disturbances
a shrunken brain.
Although alcohol can cause you to fall asleep, the quality of the sleep that follows tends to be poor. This is why people with depression should not use alcohol to try to improve their sleep, since it will actually have the opposite effect.
Excessive alcohol intake can also lead to legal problems. These may result from driving offences, drunk and disorderly behaviour, or violent crime due to the impulsivity and lack of self-control caused by alcohol. Involvement with the legal establishment does not tend to help a depressed mood.
Alcohol problems account for:
33 per cent of domestic accidents
40 per cent of fatal domestic fires
15 to 30 per cent of workplace accidents.
Depression is also associated with an increased rate of accidents and so the combination can be worrying.
Some antidepressants are sedative. If they are taken with alcohol, a person can be seriously sedated and at risk of their breathing stopping. In addition, many antidepressants are broken down in the liver. Because alcohol can damage the liver, the levels of these antidepressants in the body will be higher in people who are also drinking heavily. This can lead to an increase in side effects from the antidepressants.*
