Know Your Numbers Week: Blood Pressure is Only Half the Story

There is a lot to appreciate regarding the Know Your Numbers Week campaign. It is an extremely worthwhile endeavour. Nevertheless, it solely examines one number: blood pressure. This is the key to understanding the limitations of Know Your Numbers Week,

Know Your Numbers Week is sponsored by Blood Pressure UK, and supported by NHS England. It is a simple premise: go get your blood pressure checked because many individuals with high blood pressure do not experience symptoms until it is too late. NHS England refers to the group of individuals unaware of their elevated blood pressure levels as “the missing millions”. These individuals are undetected, because nothing hurts and nothing feels wrong.

According to NICE guidelines (NG136), a single elevated reading within a clinical setting does not conclusively diagnose hypertension. Ambulatory or home blood pressure monitoring for multiple days should be performed after obtaining a reading in excess of 140/90mmhg in order to accurately determine whether or not an individual has hypertension. In essence, a blood pressure reading obtained using a cuff is only a temporary measurement, and therefore will vary based upon stress, caffeine consumption, etc., as well as anxiety related to simply visiting a doctor’s office.

Therefore, a blood pressure reading obtained in a clinical setting provides only One piece of information regarding overall health. Elevated blood pressure readings do not provide insight regarding Cholesterol levels; nor do they reflect kidney function; nor do they indicate how an individual’s body is functioning relative to glucose. All three of these systems operate independently of blood pressure, and each contributes significantly to cardiovascular health.

Three additional pieces of information that a blood pressure cuff is unable to measure include:

1. Cholesterol: NICE guidance on cardiovascular risk uses more than a total cholesterol figure, it looks at the ratio between total cholesterol and HDL ("good") cholesterol, alongside non-HDL cholesterol, because two people with an identical total cholesterol number can carry very different actual risk depending on that split. You cannot see any of this from a blood pressure monitor.

2. Kidney function: Raised blood pressure and kidney dysfunction affect One another. Raised blood pressure may eventually cause damage to the small blood vessels within the kidneys, whereas early kidney disease may cause raised blood pressure prior to displaying other signs. According to NICE’s CKD guidance (NG203), kidney function tests should be routinely monitored when evaluating blood pressure in relation to kidney function. Prior to experiencing any symptoms, early signs of kidney dysfunction may be detected utilizing a basic kidney marker such as creatinine present within a blood sample.

3. Blood sugar levels:  Hypertension and type-2 diabetes frequently coexist. Clinicians are educated to view hypertension when diagnosing and managing type-2 diabetes. Both conditions rarely display symptoms early on. A blood pressure cuff is incapable of measuring either.

Myth vs factMyth: “since my blood pressure was normal, my cardiac risk is also normal.” fact: blood pressure is merely One component utilized in calculating an individual’s cardiovascular risk; however, it is certainly not the sole factor.

It is essential to note that Know Your Numbers Week was not intended to serve as a comprehensive health evaluation. Rather, it serves as a screening device for One particularly significant, yet silent cardiovascular-related condition. While the campaign is successful in encouraging individuals to screen themselves for elevated blood pressure readings, participants should understand that the findings from Know Your Numbers Week do not represent a definitive assessment of their cardiovascular health.

Comparison between each type of screening tool used during Know Your Numbers Week:

Check	What it tells you	What it misses
Pharmacy or home blood pressure cuff	Systolic/diastolic blood pressure on the day	Cholesterol, kidney function, blood sugar, liver health
NHS Health Check (ages 40 to 74, every 5 years)	Blood pressure, total cholesterol, a diabetes risk questionnaire, cardiovascular risk score	A full lipid breakdown (HDL/LDL/ratio), a direct kidney marker, and it isn't available at all under 40
A private blood test panel (e.g. Complete Wellness Check)	Cholesterol breakdown, kidney and liver markers, blood glucose, full blood count, often 30+ biomarkers together	Nothing in the panel itself, though it still needs a BP reading alongside it for the full cardiovascular picture

That table has one row worth sitting with. Two of the three things a blood pressure cuff can't see, kidney function and blood sugar control, are silent conditions with essentially no symptoms in their early stages. The only reliable way most people find out is a blood test.

Who Needs the Fuller Picture

Individuals who belongs to these three categories requires the fuller picture: individuals aged between 30–40 who have not undergone Cholesterol or kidney assessments due to lack of recommendation by healthcare professionals. Family members of parents/siblings who experienced heart attacks/strokes/kidney diseases, since family history alters the degree to which certain blood pressure values contribute to an individual’s risk. Patients beginning weight loss medications since baseline kidney and metabolic assessments are required before commencing therapy.

In private blood test service, none of the preceding requirements necessitate a physician referral or lengthy waits. Adults desiring access to baseline data assessing kidney/liver/glucose functions may obtain the information via private blood testing panels available throughout the uk (typically tested at-home/workplace). Private blood testing panels cover Cholesterol/kidney function/blood glucose in a single test visit; however, patients receive explanations of their results from physicians, as opposed to simply receiving printed reports containing numerous measurements devoid of interpretation.

Additionally, adults interested in creating personalized profiles surrounding their unique histories (as opposed to generic panels) may choose to opt for the Bespoke Wellness Profile, a customized set of markers selected based upon age/symptoms/family history, rather than One-size-fits-all lists.

Commonly Asked Questions :

Does Know Your Numbers Week relate solely to blood pressure?

Yes. Although Know Your Numbers Week relates exclusively to blood pressure screenings, the initiative is sponsored by Blood Pressure UK and endorsed by NHS England. Furthermore, Know Your Numbers Week does not assess Cholesterol/kidney or blood sugar levels.

Are you at risk for heart/kidney problems even with normal blood pressure readings?

Yes. In addition to various indicators associated with cardiovascular/kidney disease risk including total Cholesterol ratios, kidney markers and blood sugar levels, blood pressure represents only One of several contributing factors. Consequently, although an individual obtains normal readings for his/her blood pressure and possesses a poor Cholesterol ratio/early signs of kidney dysfunction; he/she remains at risk for future cardiovascular issues and/or kidney dysfunction, thus providing evidence that discussion with a healthcare provider is warranted if you possess any risk factors i.e. Family history.

Do I need to see my physician in order to obtain my Cholesterol/kidney function tested?

Not necessarily. The NHS Health Check provides this testing service for all adults between ages 40-74, every five years; however, a private blood test panel can be ordered at any time without seeing your physician if you prefer not to wait or do not meet the eligibility criteria established by The NHS Health Check program.

How often I should get these blood tests done?

While there exists no singular guideline applicable to all adults; frequency of assessment generally correlates with age/family history/existing risk factors. Generally speaking, adults possessing no pre-existing risk factors typically assess their levels annually, while those with family histories/previously borderline levels should discuss frequency with their respective clinicians.

What is included within a private blood test panel that covers these areas?

Typically, private blood test panels (such as the Complete Wellness Check) include complete Cholesterol breakdown; kidney/liver markers; glucose levels; and a complete blood count, dozens of markers from a single blood draw, usually conducted at-home/workplace, wherein clinicians interpret the results.
