Extreme stress can trigger depression. Recent research shows that some people are biologically programmed to react with depression when they are over stressed. Poor diet and nutritional deficiencies can contribute to feeling blue. Nearly all of us have felt depressed at some point in our lives and, very often, within a short time we bounce back to normal. But when the depression doesn't lift within a week or two, it may be a sign of clinical depression , a bona fide health problem that may worsen if it is not effectively treated.
Symptoms are wide-ranging and are often mistaken for other ailments.
Common signs of depression include insomnia, digestive problems, fatigue, headache, muscle pain, forgetfulness, lack of ability to concentrate, weight loss or gain, and withdrawal from social and business life. In my experience, I have also seen cases in which nutritional deficiencies have contributed to depression, and when the right combination of diet and supplements has made a real and palpable difference. Depression may be caused by a wide range of factors, including childhood traumas or current events, such as the loss of a job or a loved one. But almost all depression is characterized by feelings of helplessness and loss of control over your life. Recently, researchers have been investigating the physical causes of depression, that is, whether certain chemical changes may contribute or trigger depression.
