Insights
This study found no difference in the prevalence of common symptoms like headache or dizziness between individuals with high blood pressure (hypertension) and those with normal blood pressure. Popular beliefs about hypertension symptoms are not supported by this research.
Area of Science:
- Cardiology
- Public Health
Context:
- High blood pressure (hypertension) is often asymptomatic.
- Commonly attributed symptoms like headache, epistaxis, and dizziness lack scientific validation.
- Understanding symptom prevalence is crucial for public awareness and early detection.
Purpose:
- To compare the prevalence of specific symptoms in individuals with and without high blood pressure.
- To investigate the association between hypertension and commonly perceived symptoms.
- To challenge popular misconceptions regarding hypertension symptomatology.
Summary:
- A study in Chile compared symptom prevalence in 1048 individuals with hypertension and 1052 with normal blood pressure.
- No statistically significant differences were found in the prevalence of headache, epistaxis, dizziness, tinnitus, or subconjunctival hemorrhage.
- Results indicate that these symptoms are not reliable indicators of high blood pressure.
Impact:
- Challenges the popular belief that certain symptoms indicate high blood pressure.
- Provides evidence-based information for healthcare professionals and the public.
- Highlights the importance of regular blood pressure monitoring over symptom-based self-diagnosis.
Background:
High blood pressure should be symptomless. However, popular knowledge attributes some symptoms such as headache, epistaxis or dizziness to high blood pressure.
Aim:
To compare the prevalence of headache, epistaxis, subconjunctival hemorrhages and dizziness in people with normal or high blood pressure.
Subjects And Methods:
A representative sample of an urban population in Chile was studied. Each subject with high blood pressure was paired with a non-related individual of the same sex and age. These subjects were interrogated about the presence of symptoms.
Results:
One thousand forty eight subjects with high blood pressure (481 male) and 1052 individuals with normal pressure (483 male), were studied. In subjects with high or normal blood pressure, the prevalence of headache was 22 and 21.8% respectively, epistaxis was 11.6 and 11% respectively, dizziness was 7.4 and 7.6% respectively, tinnitus was 9.1 and 9.4% respectively and subconjunctival hemorrhage was 2.9 and 3.1% respectively (p = NS).
Conclusions:
No differences in the prevalence of symptoms, popularly attributed to hypertension, were observed between subjects with normal or high blood pressure.

Alterations in Blood Pressure
Hypertension (High blood pressure)
Hypertension occurs when blood pressure readings consistently exceed the normal range. It is diagnosed when systolic blood pressure (the top number, indicating pressure while the heart beats)...
Hypertension I: Introduction
Special considerations while measuring blood pressure
Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
