About the topic
A head injury may need urgent assessment even when it looks minor. Vomiting, dizziness or taking blood-thinning medicines are reasons to seek urgent medical advice.
Practical care & comfort
- If a clinician says home observation is appropriate, have an adult stay for the first 24 hours.
- Rest and follow discharge advice.
- Avoid alcohol, sleeping tablets unless advised, and driving until recovered.
Symptoms & signs
- Headache or swelling after a blow to the head.
- Dizziness or vomiting, which needs urgent advice.
- Unusual drowsiness, weakness or speech changes are emergency warning signs.
When to speak with a clinician: Seek review if symptoms persist or you are unsure about returning to work or sport.
Food & nutrition
Food cannot treat a brain injury. Emergency symptoms take priority; the treating team decides whether swallowing or feeding support is needed.
Foods & nutrition to follow
- After assessment, follow discharge instructions about meals and fluids.
- When fully alert and swallowing safely, use ordinary balanced meals.
Foods to limit or avoid
- Give nothing by mouth if drowsy, confused or unable to swallow safely.
- Avoid alcohol while recovering.
