This symptom is often associated with headaches, but sometimes patients report nausea as their primary symptom to come to the emergency room. In some cases, nausea is severe and causes vomiting, but it is not always the case. In hypertension, it is essential to look at the relationship between the signs and symptoms because each one of them would not have a clinical meaning by itself.
For example, nausea is often caused by gastrointestinal problems such as food poisoning. But having nausea, a headache and blurred vision should lead us to think there’s something more significant than a digestive problem going on.
