Dizziness and fainting followed by a head injury?


Hello Dr.
Hong, my girlfriend is in Spain.
A couple of days ago, she suddenly fainted in the kitchen and hit her head.
When she went to see a doctor, the doctor requested some physiological response tests, such as whether her eyes could focus and if she could stand still with her eyes closed without swaying.
The doctor diagnosed her with no major issues but mentioned a mild head injury and advised her to observe for 48 hours.
She is currently taking pain relievers and antipyretics, and she will stop the medication the day after tomorrow.
The fever she had on the night of the fainting has subsided.
However, due to language barriers, there wasn't much inquiry about the cause of her fainting.
My girlfriend speculates that the fainting might have been due to a fever the night before, and when she got out of bed the next morning, she stood up and walked without any buffer, which might have caused some anemia and physical weakness, leading to her fainting.
Currently, she does not experience dizziness or vomiting.
I would like to consult about the possibility of a brain hemorrhage and what dietary considerations she should have, including what to increase and what to avoid.

Dr. Hong Yuanbin reply Internal Medicine


Hello, it is recommended to monitor for severe headaches or vomiting within the next 48 hours.
If either occurs, you should promptly return to the emergency department for evaluation of potential intracranial hemorrhage.
If no significant symptoms develop afterward, the likelihood of a brain bleed is lower, and you can simply observe.
As for dietary adjustments, there are no specific changes needed.
Thank you for your inquiry.

When it comes to understanding dizziness and head injuries, especially in the context of your girlfriend's recent incident, there are several important factors to consider for recovery and ongoing health.
Firstly, it’s reassuring that the initial medical evaluation indicated only a mild head injury. However, it’s crucial to remain vigilant for any potential complications, such as intracranial bleeding. Although the doctor did not find any immediate issues, symptoms such as persistent headache, confusion, difficulty speaking, or changes in vision should prompt a return to medical care. The risk of brain bleeding, particularly after a fall or impact, can sometimes manifest hours or even days later, so monitoring her condition closely is essential.

In terms of recovery, the 48-hour observation period is standard practice following a mild head injury. During this time, it's important for her to rest and avoid any strenuous activities. If she experiences any worsening symptoms, she should seek medical attention immediately.
Regarding her dizziness, it’s possible that the fainting episode was related to a combination of factors, including dehydration, low blood pressure, or even a sudden change in posture, as you mentioned she stood up quickly. This can lead to orthostatic hypotension, where blood pressure drops upon standing, causing dizziness or fainting. Encouraging her to rise slowly from sitting or lying positions can help mitigate this risk.

Diet plays a significant role in recovery from any injury. A balanced diet rich in nutrients can support brain health and overall recovery. Here are some dietary recommendations:
1. Hydration: Ensure she stays well-hydrated, as dehydration can exacerbate dizziness and fatigue. Encourage her to drink plenty of fluids, particularly water.

2. Nutrient-Rich Foods: Incorporate foods high in antioxidants, such as fruits and vegetables, which can help reduce inflammation. Foods rich in omega-3 fatty acids (like fish, walnuts, and flaxseeds) are also beneficial for brain health.

3. Protein: Adequate protein intake is essential for tissue repair. Lean meats, legumes, and dairy products can provide the necessary protein.

4. Avoid Excessive Sugar and Caffeine: These can lead to energy spikes and crashes, potentially worsening feelings of dizziness or fatigue.

5. Iron-Rich Foods: If her fainting was related to low iron levels, incorporating iron-rich foods (like spinach, red meat, and lentils) can be beneficial.

6. Limit Alcohol: Alcohol can dehydrate the body and may interfere with recovery, so it’s best to avoid it during this period.

In summary, while the initial assessment suggests a mild injury, it’s essential to monitor for any changes in her condition. Encourage her to maintain a balanced diet, stay hydrated, and rest adequately. If any concerning symptoms arise, she should not hesitate to seek further medical evaluation. Recovery from head injuries can vary significantly from person to person, so patience and careful attention to her body’s signals will be key in her healing process.
