Depression is a common but serious mental health disorder that negatively affects how a person feels, thinks, and behaves. It is more than just occasional sadness—it involves persistent feelings of hopelessness, emptiness, or loss of interest in activities once enjoyed, lasting for weeks or months. Depression can interfere with daily life, work performance, relationships, and physical health.
The causes of depression are complex and often involve a combination of biological, psychological, and environmental factors. Chemical imbalances in the brain, genetic predisposition, traumatic experiences, chronic illnesses, or significant life changes can trigger the condition. Symptoms may include fatigue, difficulty concentrating, changes in appetite or sleep patterns, irritability, and in severe cases, thoughts of self-harm or suicide.
