Certain medications or substance use: Alcohol and drug misuse can contribute.
Personality factors: Low self-esteem, pessimism, or difficulty coping with stress.

A healthcare professional diagnoses depression by:
Taking a detailed medical and psychiatric history.
Asking about symptoms, their severity, and duration.
Performing a physical examination to rule out medical causes.
Using screening questionnaires such as the PHQ-9.
Ordering blood tests if needed (e.g., thyroid function, vitamin B12, or other tests) to exclude other conditions.
Common Symptoms
Persistent sadness or low mood.
Loss of interest or pleasure in usual activities.
Fatigue or low energy.

Poor concentration or difficulty making decisions.
Feelings of worthlessness or excessive guilt.

Regular physical exercise.
Healthy, balanced diet.
Good sleep habits.
