Although depression can be a standalone mental health condition, it is often caused by or the cause of other illnesses or conditions. A swift and accurate diagnosis of these illnesses, along with treatment, can make the conditions and symptoms much more manageable.
Medical illnesses that can cause depression include cancer, cardiovascular conditions, immune system disorders and diabetes. However, depression can accompany any debilitating disease that affects a patient’s lifestyle habits, self-sufficiency, self-esteem, life expectancy, or finances. Furthermore, the use of drugs or excessive alcohol consumption is known to cause and worsen depression symptoms.
