2 min read

A significant number of people experience nausea following physical trauma, often triggered by the body’s complex stress response or an underlying injury. The question, Can you get nauseous from an injury?, is not only yes, but a crucial symptom to understand for your health and recovery.

Quick Summary

Feeling sick after an injury is a common reaction, as physical trauma and emotional stress can disrupt the body’s nervous system, inner ear, or even signal more serious internal damage like a concussion or bleeding. This response can be immediate or delayed, making it essential to monitor any new symptoms and seek medical evaluation.

Key Points

Nausea is a Common Symptom: Feeling nauseous after an injury is not unusual and can stem from both physical and psychological factors.
Delayed Symptoms are Possible: Symptoms like nausea from concussions or internal bleeding can appear hours or days after the initial injury.
Concussions and Internal Bleeding are Serious Causes: Head injuries and abdominal trauma are two serious causes of post-injury nausea that require prompt medical attention.
Stress and Adrenaline Play a Role: The body's stress response and the subsequent adrenaline crash can trigger feelings of sickness even without a major physical injury.
Accompanying Symptoms Demand Action: Nausea paired with persistent headaches, confusion, or severe pain warrants immediate medical evaluation.
Seeking Medical Care is Key: Always consult a healthcare professional to diagnose the root cause of post-injury nausea and ensure proper treatment.

The Physical and Psychological Reasons You Feel Sick

Nausea after an injury can stem from various sources, both physical and psychological. Paying attention to these signals is important for identifying potential underlying conditions.

Concussions and Traumatic Brain Injury (TBI)

A concussion, caused by a sudden impact, can disrupt brain function and lead to nausea, dizziness, confusion, headaches, and sensitivity to light or sound. Symptoms may be delayed.

Whiplash and Neck Injuries

Whiplash, often from rapid back-and-forth head movement, can affect the vestibular system in the inner ear, which controls balance. This disruption can cause vertigo and dizziness, frequently resulting in nausea.

Internal Injuries and Bleeding

Nausea can be a critical sign of internal injuries, particularly after abdominal trauma. This may occur from high-impact events and could indicate damage to organs or internal bleeding, which can be life-threatening.

Pain, Shock, and Adrenaline Crash

The body's initial response to trauma includes a surge of adrenaline and endorphins. As this subsides, an 'adrenaline crash' can cause sickness and fatigue. Intense pain can also trigger nausea.

Emotional Stress and Anxiety

The psychological impact of an injury, including stress, shock, and anxiety, can lead to physical symptoms like nausea by affecting the digestive system.

When Nausea Signals a Serious Problem

While post-injury nausea can be a normal response, some accompanying symptoms require immediate medical attention:

Persistent or severe headaches
Dizziness, confusion, or memory issues
Vision changes or slurred speech
Numbness or tingling in limbs
Severe abdominal pain or extensive bruising
Changes in consciousness or loss of consciousness

How to Respond to Post-Injury Nausea

If you experience nausea after an injury, take these steps:

Seek immediate medical attention for severe or persistent symptoms, especially with other serious signs.
Stay hydrated by taking small sips of water or electrolyte drinks.
Rest and avoid activities that worsen nausea or dizziness.
Monitor for symptom changes, noting the onset and severity.
Document your experience for medical and potential legal purposes.

Comparing Causes of Post-Injury Nausea

Understanding potential causes can help identify the source of symptoms:


Feature	Concussion (TBI)	Internal Injury	Emotional Stress/Shock
Cause	Impact to the head causing brain jostling	Trauma to abdominal or chest area	Psychological response to fear and trauma
Onset	Can be delayed for hours or days	Often delayed or gradual	Immediate or delayed
Accompanying Symptoms	Headache, confusion, vision problems, memory loss	Severe abdominal pain, bruising, dizziness	Anxiety, rapid heart rate, fatigue, loss of appetite
Severity	Can be very serious; requires medical evaluation	Life-threatening; requires immediate medical care	Can be temporary, but still important to monitor

Conclusion: Never Ignore the Warning Signs

Feeling nauseous after an injury should be taken seriously. It can be a sign of anything from a stress response to a concussion or internal bleeding. Due to the possibility of delayed symptoms, continuous monitoring and seeking professional medical help are crucial. Always consult a healthcare provider to determine the cause of your nausea and ensure proper care. For more information on head injuries, visit the CDC.

Frequently Asked Questions

An injury can cause nausea by disrupting the body's internal systems in several ways. This includes jolting the brain (concussion), affecting the balance center in the inner ear (whiplash), causing internal bleeding or organ damage (abdominal trauma), or as a side effect of emotional shock, pain, and the ensuing adrenaline crash.

Nausea from an injury can manifest either immediately or be delayed for hours or even days. A delayed onset is particularly common with concussions and internal injuries, as the body's initial adrenaline response can mask early symptoms.

Yes, it is relatively common to feel sick after a car accident due to the intense stress, potential whiplash, or hidden head and internal injuries sustained during the collision. Never dismiss nausea after an accident, as it could be a warning sign of a serious medical issue.

You should see a doctor immediately if the nausea is severe, persists for more than a couple of hours, or is accompanied by other concerning symptoms like a persistent headache, confusion, dizziness, or vision changes. These can indicate a serious injury, such as a concussion or internal bleeding.

Yes, the psychological and emotional shock of a traumatic event can absolutely cause physical symptoms like nausea. The body's intense stress response triggers hormonal and digestive changes that can result in feeling sick to your stomach.

Yes, even seemingly minor injuries can cause nausea. The body's response to pain, mild trauma, or the stress of the event can all lead to a feeling of sickness. However, it is always wise to get checked out, as a seemingly minor symptom could mask a more serious issue.

The duration of nausea from an injury varies greatly depending on its cause. Stress-related nausea might subside quickly, but if it's from a concussion or internal injury, it could last much longer and potentially worsen. Any persistent nausea beyond 24-48 hours should be evaluated by a medical professional.
