What is depression?
Depression is an illness that makes you feel sad and miserable over a long period of time. People who are depressed have difficulty coping with everyday life and may even feel suicidal. Depression is associated with a wide range of symptoms and can be treated.
Who suffers from depression?
Anybody can get depressed at any time of their life. However, some people seem to be more prone to depression than others. This may be because of previous experiences or because of their body chemistry. Women are twice as likely as men to become depressed.
What causes depression?
Depression is a result of disturbances in your body chemistry. These disturbances can be triggered by traumatic or stressful events, such as bereavement, marriage or relationship problems, unemployment, redundancy, retirement, financial difficulties, an operation, childbirth or an illness. However, it is equally common for depression to have no obvious cause. Seasonal affective disorder (SAD) is a special type of depression, which occurs mainly in the winter (when there are fewer hours of sunlight during the day) and can be treated with light therapy. Postpartum depression may occur in women after giving birth. It may develop up to a year later but in most cases it occurs within the first three months after delivery.

How is depression treated?
Depression is treated with counselling and antidepressant drugs. Antidepressants can be taken over a long period of time and are not addictive. However, they need to be taken regularly for some weeks to have an effect and then continued for at least six months to avoid relapse of depressive symptoms. Some people experience side effects such as a dry mouth or feeling sick when they first take antidepressants, but these usually wear off after one to two weeks. There are several different kinds of antidepressants but they all aim to correct the chemical imbalance in the body that is thought to causes the symptoms of depression. Your doctor will prescribe an antidepressant which he or she thinks is best suited to you as an individual.
Counselling helps you talk through your feelings and any problems. If you need counselling your doctor will refer you to a counsellor.
- Learn how to relax using relaxation exercises and tapes, yoga, meditation or aromatherapy to relieve the tension, anxiety and irritability of depression.
- Exercise to stimulate your levels of brain chemicals and make you feel more alert and motivated.
- Slow down your pace of life: take a holiday, try to reduce your work stress and take short rests (even if only for a few minutes) during the day.
- Eat a well-balanced diet. Depression may tempt you to under- or overeat (especially junk food). A diet lacking the necessary vitamins and minerals can make you feel worse.
- Avoid smoking, illegal drugs and alcohol. These may give you a short-term "high", but are not helpful in the long run.
- Keep occupied, through a hobby, reading a book or even watching television. You will dwell on your depression when inactive, making you feel worse.
- Join a self-help group. Discussing your fears and symptoms with other sufferers will help you feel less isolated. Details of self-help groups are available through Depression Alliance.
