Depression & Fatigue
January 30, 2009
Depression is affecting more and more Americans by the day. It is one of the most serious diseases, which can be debilitating. Fatigue has now been recognised as being caused due to depression.
The reason behind depression
As is the general belief, a negative or traumatic life is not the only cause of this condition. It is quite normal if you feel sad when you suffer loss of a loved one or a loving relationship. However, it does not remain normal anymore if it continues even after weeks or months.
The main reason behind depression is a chemical imbalance in the brain. This imbalance causes the feelings of sadness, hopelessness and emptiness.
Depression can also be caused by seasons. Northern countries like Sweden, where you do not get a lot of sunlight everyday, can induce a condition called seasonal affective disorder (SAD). This causes depression among a large number of people there.
Even some medications have known to cause depression. Non-steroidal anti-inflammatory drugs (NSAIDs) like Aleve or Advil (ibuprofen) can aggravate depression in people who already are victims.
Some medications, including tranquilizers, sedative, anti-histamines, high blood pressure medications and antipsychotic drugs, also contribute to depression.
Symptoms
If you have noticed fatigue, diminished interest or pleasure, anxiety, sleep disturbances, significant change in appetite and/or weight gain, sluggishness, restlessness, lack of energy and suicidal thoughts, then you might be suffering from major depression.
A Canadian study showed that 96% of depressed patients showed fatigue or a lack of energy as specific symptoms, while 72% of these were unable to get on with their lives because of these symptoms.
Treatment
Depression can be treated by exercise and medication.
Mild exercises like regular jogs or walks have shown to reduce depression. This can be pretty effective in cases of mild depression.
Several medications are available to treat depression. However, most often they do not address the most incapacitating symptoms of fatigue and lethargy. Some anti-depressants that act upon the norepinephrine and dopamine in the brain are more energising than others are.
While mild depression can be treated effectively with either medication or psychotherapy, severe cases require both.
