What Is Depression?
The cause of depression has no simple answers as genetic, biological, and environmental factors may contribute to its development. Depression can be traced to a single cause or a number of causes could be at play.
Medical conditions like heart disease, cancer, and HIV may trigger depression, which may be due to the physical weakness and stress these conditions bring on. Depression can also make medical conditions worse.
Genetics may be a cause of depression as it can run in families for generations.
People who have low self-esteem and a negative outlook are at higher risk of becoming depressed.
Anxiety disorders, eating disorders, schizophrenia, and (especially) substance abuse often appear along with depression.
