[h=2]Post-traumatic Stress Disorder(PTSD).[/h] When in danger, its natural to feel afraid. This fear triggers many split-second changes in the body to prepare to defend against the danger or to avoid it. This fight-or-flight response is a healthy reaction meant to protect a person from harm. But in post-traumatic stress disorder (PTSD), this reaction is changed or damaged. People who have PTSD may feel stressed or frightened even when theyre no longer in danger.
PTSD develops after a terrifying ordeal that involved physical harm or the threat of physical harm or threats of imminent
death that result in feelings of intense fear, horror, and powerlessness. The person who develops PTSD may have been the one who was harmed, the harm may have happened to a loved one, or the person may have witnessed a harmful event that happened to loved ones or strangers.
PTSD was first brought to public attention in relation to war veterans, but it can result from a variety of traumatic incidents, such as mugging, rape, torture, being kidnapped or held captive, child abuse, car accidents, train wrecks, plane crashes, bombings, or natural disasters such as floods or earthquakes.
Many people who go through traumatic events have difficulty adjusting and coping for a while, but they don't have PTSD with time and good self-care, they usually get better. But if the symptoms get worse or last for months or even years and interfere with your functioning, you may have PTSD.
