Understanding Shock: Causes, Symptoms, and Treatment
Shock is a life-threatening condition that occurs when the body does not get enough blood flow. This can be caused by many factors, including:
* A sudden drop in blood volume or pressure, such as from a severe injury or blood loss
* Heart problems, such as a heart attack or arrhythmia
* Lung problems, such as a pulmonary embolism or pneumonia
* Infections, such as sepsis
* Allergic reactions, such as anaphylaxis
* Drug overdoses
Shock can lead to organ failure and death if not treated promptly. Symptoms of shock include:
* Rapid heart rate
* Weak pulse
* Low blood pressure
* Pale, cool, and clammy skin
* Nausea and vomiting
* Confusion
* Loss of consciousness
If you think someone is in shock, call 911 immediately. While waiting for help to arrive, you can:
* Elevate the person's legs
* Keep the person warm
* Loosen tight clothing
* Give the person sips of water if they are conscious and not vomiting
