High blood pressure affects almost one in three adults in the UK, new research has revealed.
Younger people were more likely to have undiagnosed high blood pressure - which is also known as hypertension - according to the Office for National Statistics (ONS).
Two-thirds of men between 16 and 24 years old with hypertension were yet to be diagnosed, it claimed, with 26 percent of women in the same age group with undiagnosed high blood pressure.
