By symptom
High blood pressure concern.
The reading came back elevated. You want the full picture before you start a prescription.
What’s actually going on
How I think about this.
Hypertension is the most common diagnosis in adult medicine and it is treated, correctly, as a condition that needs control. Alongside treatment, it is worth asking what is contributing to the number, because that can change the plan.
The drivers I see most are insulin resistance (the metabolic syndrome pattern almost always carries hypertension with it), sleep apnea (often missed, and often the largest single contributor when present), sodium-potassium imbalance (more about low potassium than high sodium for most patients), magnesium insufficiency, kidney function shifts that haven’t quite crossed the diagnostic threshold yet, hormonal patterns (aldosterone, cortisol, thyroid), chronic stress with sympathetic nervous system overdrive, and the elevated ApoB that often runs alongside.
Blood pressure also reflects vascular health, which means the read points to interventions beyond pressure itself. The same patterns drive cardiovascular event risk, cognitive decline, and erectile dysfunction. Treating the reading without treating the system is treating the symptom.
Before anything else
When high blood pressure concern needs medical evaluation.
Everything further down this page is about physiology that can contribute to this symptom. None of it replaces a conventional diagnosis, and some presentations need to be seen rather than measured. Start here.
Get emergency care now
- A reading at or above 180/120 together with chest pain, breathlessness, severe headache, vision change, weakness or difficulty speaking. This is a hypertensive emergency
- Blood pressure this high during pregnancy, or with severe headache, visual changes or upper abdominal pain in pregnancy
If any of these apply, this page is not the right next step. Call 911 or go to an emergency department.
See a physician promptly, within days
- Repeated readings at or above 180/120 without symptoms
- New high blood pressure before the age of 30, or a sudden rise in someone previously well controlled
- High blood pressure with episodes of sweating, palpitations and headache together
- High blood pressure with muscle weakness or low potassium on a blood test
Worth a routine medical evaluation
- Home readings consistently above 135/85
- Blood pressure not at target despite treatment
- A new diagnosis of high blood pressure, which warrants assessment of cardiovascular risk overall
Blood pressure is a treated condition, not an optimization target, and untreated hypertension causes harm silently over years. Where it is being managed, the metabolic and sleep contributors above are worth understanding alongside treatment.
This list covers the presentations that most often need conventional assessment. It is not exhaustive, and it does not replace clinical judgement. If something feels wrong and is not on it, that is still a reason to be seen.
Systems that can contribute
Where high blood pressure concern can come from.
Each of these can be part of the picture. None of them is the answer on its own, and finding something here does not establish that it is the reason you feel the way you do.
Insulin and metabolic regulation
Insulin resistance and blood pressure travel together frequently enough that finding one is a reason to look for the other.
Sleep and breathing
Obstructive sleep apnoea is one of the most common identifiable contributors to blood pressure that will not come down, and it is frequently missed.
Sodium, potassium and renal handling
The balance between them, rather than sodium alone, is what the evidence supports.
Autonomic tone and stress physiology
Sympathetic activity contributes, which is part of why readings taken in a clinic are often the highest ones a person ever records.
Vascular and inflammatory markers
Arterial stiffness and inflammatory activity can be part of the longer-term picture.
Medication and substance effects
NSAIDs, decongestants, some contraceptives, alcohol and stimulants can all raise blood pressure.
The physician’s lens
How I read this in practice.
I read blood pressure with proper measurement first: cuff size right, multiple readings, ideally home readings averaged across days. Then the cardiometabolic markers, including fasting insulin and HbA1c. Kidney function (eGFR, BUN, urinalysis), electrolytes with magnesium, the thyroid panel, hsCRP. For new hypertension, I screen for sleep apnea. The metabolomic panel adds the upstream context that often points to the specific lever to pull first.

Exposomics.
The cumulative environmental load a person carries can matter for physiology. Some of it can be measured, and I assess it when your history says it is relevant.

Chronobiology.
Every hormone, immune function, and metabolic process runs on a circadian schedule. The disruption is measurable, and the consequences are systemic.

What measurement settles
What testing can and cannot tell you here.
Testing can help identify
- Identify insulin resistance, kidney function, electrolyte abnormalities and lipid risk that sit alongside blood pressure
- Describe the cardiovascular risk picture the blood pressure sits within
Testing cannot by itself establish
- Replace actual blood pressure measurement, ideally at home over time
- Exclude secondary causes of hypertension without specific targeted testing
- Determine whether you need medication, which is a clinical decision
What may help clarify it
The data that explains it.
Blood pressure work needs the cardiometabolic markers, the kidney and electrolyte read, and the inflammation and insulin axis together. The metabolomic panel adds the upstream pattern most primary-care workups don’t catch.
What I would measure
Cardiometabolic markers
Reads ApoB, fasting insulin, kidney function, inflammation, and electrolytes. The full vascular and metabolic context.

Cellular and metabolic markers
Adds the magnesium status, B-vitamin story, and oxidative stress patterns that often shift pressure when corrected.

While you wait
Moves worth making before testing.
These are the levers I’d pull while we set up the workup. Most of them produce real signal inside two weeks.
- Measure properly at home. Same arm, same time of day, three readings averaged across a week. The reading in the clinic is often the worst one you will ever get.
- Lift heavy two to three times a week. Resistance training drops resting pressure as reliably as most medications.
- Cut alcohol entirely for two weeks. Even moderate intake raises pressure more than most patients realize.
- Eat more potassium. Leafy greens, beans, potatoes. The sodium-potassium ratio matters more than sodium alone.
If two weeks of the basics doesn’t move the needle, that is the kind of presentation a call with me exists for. Your biology is telling you something the lifestyle layer cannot fix on its own.
Your next step
Measure it, then decide.
There is a coherent measurement pathway here. What a panel does not include is someone reading it against your history, and that reading is where care with me begins.

A fasting insulin of 12: what it can, and cannot, tell you.
A fasting insulin of 12 may fall inside a laboratory's reference interval beside a normal glucose. It can add context that glucose and A1c do not give on their own, but it is a proxy, not a diagnosis: there is no universal cut-off, laboratories do not agree, and it is read beside standard testing and repeated before it means anything.

An Lp(a) of 150: the lab you measure once, and why it is about your family.
An Lp(a) of 150 nmol/L is elevated, it is mostly inherited, and lifestyle changes usually do not lower it meaningfully. In topline results from the first large outcomes trial of a dedicated Lp(a)-lowering drug, pelacarsen lowered Lp(a) but did not reduce major cardiovascular events. The response is not to chase the number. It is to manage the rest of cardiovascular risk more intensively, and to have your parents, siblings and adult children measured once.

What is metabolomics? A working definition for patients.
Metabolomics measures the small molecules your body produces as it runs. Some metabolite tests are already standard clinical practice; broad profiling is a newer and less settled thing. In my practice it is a core data layer, read beside your history and the ordinary labs, never a panel that explains a symptom on its own.
