Signs, Symptoms & Clinical Features
Vomiting
Vomiting, especially when persistent or associated with other signs, can be a symptom of raised intracranial pressure in hydrocephalus.
In short: Vomiting
- It can be a symptom of raised intracranial pressure.
- It is more concerning when persistent or with other signs.
- In children, morning vomiting with headache can be a warning sign.
- It is a common but nonspecific symptom.
What it is
Vomiting is the forceful emptying of stomach contents. While it has many common causes, persistent vomiting — especially with headache or other signs — can be a symptom of raised intracranial pressure in hydrocephalus.
Understanding Vomiting
Raised intracranial pressure can cause vomiting, sometimes without much nausea beforehand. In children, a pattern of headache and vomiting, particularly in the morning, can be a warning sign of raised pressure and warrants evaluation. In babies, vomiting can accompany other signs such as a bulging fontanelle, irritability, and rapid head growth. Because vomiting is so common and usually due to benign causes (like a stomach virus), it is most concerning for hydrocephalus when it is persistent, unexplained, or accompanied by other signs of raised pressure. The pattern and associated findings guide evaluation.
Why it matters
Understanding vomiting as a possible symptom helps families recognize that persistent or unexplained vomiting, especially with headache or other signs, can indicate raised pressure and should be evaluated.
Common questions
Can vomiting signal hydrocephalus?

What pattern is concerning in children?
Morning headache with vomiting.
Is vomiting usually due to hydrocephalus?
No — it is common and usually benign, but the pattern matters.
Bottom line
