Does Depression always need to be Treated?

If someone has mild depression, or it has only just started, one option is to wait and see whether the symptoms go away again without treatment. This “Watchful Waiting” approach doesn’t mean that the symptoms are ignored and nothing is done, though. It is important to stay in touch with the doctor and have regular appointments to discuss how you’re feeling and how you can cope with the situation. If the symptoms get worse or last several weeks, further treatment may be needed.

There are various treatment options for depression. They include psychological treatments, medication and general measures such as relaxation techniques. Different treatment options are often combined.
