3. Hormonal Changes: Conditions like pregnancy, postpartum, menopause, or thyroid issues can trigger depression.

4. Chronic Illness: Diseases like diabetes, heart disease, or cancer can lead to depression.

5.     Trauma and Stress: Loss of a loved one, abuse, major life changes, or financial difficulties can be triggers.

6.     Substance Abuse: Alcohol and drug use can both cause and worsen depression.

7. Lack of Social Support: Isolation or poor social connections can increase vulnerability.

8.   Personality Factors: Low self-esteem, pessimism, or being overly self-critical can contribute.

7. Atypical Depression: Symptoms include mood improvement in response to positive events, increased appetite, and excessive sleep.

8.  Situational Depression: Triggered by specific life events, like losing a job or loved one.



Treatment of Depression

Treatment varies based on the type and severity of depression but typically includes:

1.      Therapy:

3.      Lifestyle Changes:

o    Stress management techniques

4.  Support Groups: Sharing experiences with others facing depression can offer support and reduce feelings of isolation.

5.     Alternative Therapies:

o    Yoga and meditation for relaxation.

o    Acupuncture and herbal supplements (with medical supervision).

6.  Electroconvulsive Therapy (ECT): Used in severe cases where other treatments haven’t worked.

7.Transcranial Magnetic Stimulation (TMS): A non-invasive procedure that stimulates the brain using magnetic fields.

8.  Hospitalization: Required in cases of severe depression, especially if there’s a risk of self-harm.
