Medical depression is not a disease but a mental illness. It may be caused by a combination of factors such as psychological, genetic, environmental and biological factors. Depression is said to run in families even though there are people who suffer from depression with no known genetic predisposition. It is claimed that depression is also caused by a chemical imbalance in the brain. Depression may be caused by trauma, stress, loss of a loved one and other environmental factors.
The symptoms of medical depression are many and varied. Diagnosis of depression is based on whether or not you have been suffering from any number of the common symptoms for 2 weeks or more. The most common symptoms of medical depression include headaches, change in appetite (lack of appetite or over-eating), fatigue and lack of energy, unexplained physical symptoms with no known cause. These are some of the physical symptoms.
