Severe trauma refers to a significant injury or emotional shock that can have lasting effects on an individual's physical and mental health. This type of trauma can result from events such as accidents, natural disasters, or violent incidents. It often leads to symptoms like intense fear, anxiety, and difficulty functioning in daily life. In medical terms, severe trauma can also describe critical injuries that require immediate attention, such as those sustained in car crashes or falls. Treatment may involve surgery, rehabilitation, and psychological support to help individuals recover and cope with their experiences.
