The problem

Hypertension is treated, never investigated.

1 in 4 Indian adults has hypertension. Most are prescribed amlodipine or telmisartan and sent home. No one tests kidney function, aldosterone, cortisol, or insulin resistance — the actual drivers of elevated blood pressure. This means millions are on medication that controls a number without fixing the underlying problem. Hypertension often coexists with diabetes, thyroid dysfunction, and obesity.

The science

Markers we read for blood pressure

These biomarkers reveal the root causes — and what actually works to fix them.

Kidney Function
Creatinine, eGFR, BUN. Kidneys regulate blood pressure. Early kidney damage elevates BP silently. Testing reveals if your hypertension is kidney-driven.
Electrolytes
Sodium, potassium, magnesium. Sodium-potassium balance directly governs blood pressure. Most Indians consume 2-3x recommended sodium. Potassium and magnesium deficiency worsen it.
Aldosterone & Renin
Hormones that control salt-water balance. Primary aldosteronism causes ~10% of hypertension cases — but is rarely tested in India.
Insulin & HbA1c
Fasting insulin + HbA1c. Insulin resistance drives hypertension in 40%+ of cases. High insulin causes sodium retention and vascular stiffness.
Cortisol (AM)
Chronic stress elevates cortisol, which raises blood pressure. Cushing's-like patterns are common in high-stress professionals.
Lipid Panel
LDL particle size, triglycerides, ApoB. Dyslipidemia and hypertension together multiply cardiovascular risk.
The reality

High blood pressure is silent until it's dangerous. 1 in 3 Indian adults has hypertension, and 50% don't know it. But here's what most miss: blood pressure is a symptom, not a diagnosis.

Insulin resistance, high cortisol, kidney dysfunction, and sleep apnea all drive elevated BP. Without testing the root cause, you're treating a number, not a problem.

Evidence

Research behind the science

Study 1

Prevalence of hypertension in India is approximately 1 in 3 adults (32–33%), with nearly 50% unaware of their condition due to lack of systematic screening and detection programs across primary healthcare.

Study 2

Insulin resistance is present in 40–50% of hypertensive patients and is a key independent driver of elevated blood pressure through mechanisms including sodium retention, increased sympathetic activity, and vascular stiffness.

Study 3

Primary aldosteronism occurs in 10–12% of unselected hypertensive populations and is a significant, often undiagnosed, secondary cause of hypertension that responds to targeted mineralocorticoid antagonist therapy.

Study 4

Comprehensive screening for multiple biomarkers (kidney function, aldosterone, cortisol, insulin, lipids, electrolytes) identifies secondary and modifiable causes of hypertension in 20–30% of patients previously thought to have essential hypertension.

Study 5

Potassium and magnesium supplementation, combined with sodium reduction, can reduce systolic blood pressure by 10–15 mmHg in hypertensive patients — a magnitude comparable to many antihypertensive drugs.

Remember

Five things to know about blood pressure

High BP is a symptom, not a disease. Treating only the number while ignoring the root cause is like silencing a smoke alarm instead of extinguishing the fire.

Insulin resistance drives up to 50% of hypertension cases. If your fasting insulin is high, your BP medication won't fix the underlying problem without addressing insulin sensitivity.

Kidney function, electrolytes, and aldosterone matter as much as salt intake. Most Indians don't know their eGFR or aldosterone levels—yet these determine whether your kidneys can regulate BP.

Medication can control BP but won't reverse the underlying cause. Lifestyle optimization + targeted biomarker-driven treatment is the path to either reducing medication or eliminating it entirely.

1 in 3 Indians has hypertension, and 50% don't know it. Silent killer or not, your BP is preventable and reversible — but only if you investigate the cause, not just the number.

Why arq. for blood pressure

Most platforms
Prescribe BP medication based on a cuff reading. No bloodwork. No investigation of cause. You take a pill forever without knowing why your BP is high.
arq. approach
Test kidney function, electrolytes, aldosterone, insulin, cortisol, and lipids. Your physician identifies why your blood pressure is elevated — and treats the cause, not just the number.

Questions

Frequently asked about blood pressure

What causes high blood pressure?
Multiple factors: kidney dysfunction, insulin resistance, hormonal imbalances (aldosterone, cortisol), electrolyte imbalance, obesity, stress, and genetics. Most doctors prescribe medication without testing which factor drives YOUR hypertension.
Can bloodwork reveal why my BP is high?
Yes. Kidney markers, aldosterone, insulin, cortisol, and electrolytes identify the specific mechanism. This changes treatment from generic to targeted.
What is primary aldosteronism?
A condition where adrenal glands produce too much aldosterone, causing sodium retention and elevated BP. It affects ~10% of hypertensive patients but is rarely tested in India.
Can insulin resistance cause high blood pressure?
Yes. High insulin causes sodium retention, vascular stiffness, and sympathetic nervous system activation — all of which raise blood pressure. Treating insulin resistance can normalize BP.
Do I need to stay on BP medication forever?
Not necessarily. If the root cause is addressable (insulin resistance, electrolyte imbalance, hormonal), targeted treatment can reduce or eliminate medication need.
How often should I get bloodwork for hypertension?
Every 90 days while optimizing treatment. Annually once stable. Kidney function and electrolytes should be monitored with any medication changes.
Is salt the only dietary factor?
No. Potassium, magnesium, and fiber intake matter equally. Most Indians are deficient in potassium and magnesium while consuming excess sodium.
How does arq. monitor blood pressure differently?
We combine 100+ biomarker testing with physician analysis to identify the cause of your hypertension. Your protocol treats the root problem, not just the reading.
