This statistical release was previously published under the title Hypertension and measured high blood pressure.

Hypertension is the medical term for high blood pressure over a long period of time. It can lead to serious health problems such as heart failure, stroke, heart disease, or kidney disease[1].

Self-reported hypertension prevalence

Over one in ten (11.6% or 3.0 million) people reported having hypertension in 2022, a slight increase since 2011–12 (10.2%). Males and females had similar rates of hypertension (11.7% and 11.6%).

Hypertension prevalence increased with age, almost tripling between 35–44 years to 45–54 years (from 4.7% to 12.4%). Prevalence continued to increase with age, with nearly half (45.2%) of all people aged 75 years and over reporting hypertension.

Self-reported hypertension only, excludes high measured blood pressure results.

High measured blood pressure prevalence

In addition to asking respondents whether they had ever been told by a doctor or nurse that they had hypertension or high blood pressure, they were also invited to have their blood pressure measured.

In 2022, over one in five (23.3%) adults had high measured blood pressure. This rate has increased slightly since 2011–12 (21.5%). The proportion of adults with high measured blood pressure increased with age, from one in twenty (4.5%) people aged 18–24 years to more than four in ten (42.9%) people aged 75 years and over.

Comparison of self-reported hypertension and high measured blood pressure

For people with high blood pressure there are often no symptoms or signs, as people can have high blood pressure yet feel well[1]. The inclusion of two methods (self-reported and measured) for assessing prevalence of high blood pressure in the NHS allows an assessment of whether people with the condition are aware that they have it.

In 2022, three in four (74.5%) adults with high measured blood pressure did not report having hypertension. This suggests that many people with high measured blood pressure either have not been diagnosed with hypertension by a doctor or nurse, or have not reported it. Nine in ten (92.3%) people aged 18–44 years with high measured blood pressure did not report having hypertension, compared to over half (54.0%) of people aged 75 years and over.
