Answer:
Blood pressure that is unusually high after an accident can have a range of causes and does not necessarily point to one specific injury or condition.
If you seek care immediately after an accident or are seen by first responders at the scene, it is not unusual to see a temporary spike in blood pressure. In response to stress or trauma, your body will release stress hormones into the bloodstream, including adrenaline. This can initiate a “fight or flight” response in us. Adrenaline also causes a temporary spike in blood pressure as your heart beats faster and blood vessels begin to narrow. This spike can go away after a short period of time, or may last for a few days, but will likely not create a chronic issue.
Injuries to the organs, particularly the kidney, can also be indicated by high blood pressure. Traumatic brain injuries and chest injuries may have similar symptoms.
If high blood pressure persists after some time without any injuries found, it is also possible that it is being brought on by stress or mental health issues like PTSD and anxiety. These can lead to hypertension and anxiety. Any lifestyle changes brought on by injury can also lead to high blood pressure as a result of depression or a sedentary lifestyle.
