Possible triggers
Depression is a complex condition with many possible causes.
Even though a person may be more susceptible to depression than someone else, they usually only experience a depressive episode when a stressful event triggers the condition.
Possible triggers include:
changes in daily routines
inadequate eating habits
stress at work, home, or school
feeling isolated, alone, or unloved
living with abuse or mistreatment
medical issues, such as Alzheimer’s disease, stroke, or erectile dysfunction
some medications, including certain antibiotics and blood pressure drugs
a significant life event, such as a bereavement or divorce
a traumatic incident, such as a car accident or sexual assault
However, it is important to note that not every depressive episode will have an obvious or identifiable trigger.
