Postnatal depression affects many new mothers due to hormonal changes, fatigue, and emotional stress after childbirth. Symptoms include sadness, irritability, and loss of interest in daily life. Treatment involves therapy, support groups, and, in some cases, medication under medical supervision. Emotional support from family and understanding partners plays a vital role. Early intervention helps mothers recover faster and bond with their babies. Compassionate care and awareness make healing smoother and more effective.
