What causes high blood pressure?
High blood pressure has two broad clinical categories. Primary (essential) hypertension, accounting for roughly 90–95% of adult cases, develops gradually from a mix of genetics, age, metabolic factors (insulin resistance, visceral fat), sleep quality, stress load, and diet — particularly sodium, refined carbohydrates, and alcohol. Secondary hypertension, accounting for the remaining 5–10%, has a specific identifiable cause such as kidney disease, adrenal hormone disorders, obstructive sleep apnoea, thyroid disease, or medication side effects. The distinction matters because treatment differs substantially.
In Indian adults, the most common drivers of primary hypertension that we see in clinical practice are:
- Metabolic syndrome — the combination of central obesity, insulin resistance, disturbed lipids, and high BP, which travel together because they share underlying biology
- Obstructive sleep apnoea — widely under-diagnosed in India; a major contributor to treatment-resistant BP in overweight patients, particularly men with thick necks and loud snoring
- High sodium intake — particularly in the form of pickles, papad, namkeen, restaurant food, and added salt at the table
- Chronic stress and poor sleep — sustained sympathetic activation raises resting BP
- Excess alcohol — a reversible BP driver that often gets missed in patient history-taking
- Medication side effects — common culprits include NSAIDs taken regularly for joint pain, decongestants, oral steroids, and some hormonal medications
What is secondary hypertension?
Secondary hypertension is high blood pressure caused by an identifiable underlying condition — rather than developing from general metabolic and lifestyle factors. Common causes include kidney disease, adrenal hormone disorders (primary aldosteronism, pheochromocytoma), obstructive sleep apnoea, thyroid disease, renal artery narrowing, and certain medications. It accounts for roughly 5–10% of adult hypertension cases but a much higher proportion of young-onset, severe, or treatment-resistant cases.
Secondary hypertension is worth identifying because many of its causes are partially or fully treatable — which means the hypertension itself may resolve or become much easier to control once the underlying condition is addressed. A patient with untreated sleep apnoea, for example, may struggle with three-drug resistant hypertension for years, when CPAP therapy alone would bring their BP to target.
We screen for secondary causes in any patient with: new-onset hypertension under age 40, sudden worsening of previously controlled BP, resistant hypertension (uncontrolled on three optimised medications), clinical features suggesting an adrenal or renal cause, or BP that does not dip at night on ambulatory monitoring.
Resistant hypertension — when three drugs still are not enough
Resistant hypertension is defined as blood pressure that remains above target despite optimal doses of three antihypertensive medications — typically including a diuretic — or requires four or more drugs to achieve control. It affects roughly 10–15% of treated hypertensive patients. In many cases, a treatable underlying cause (particularly primary aldosteronism or obstructive sleep apnoea) has been missed.
Before accepting that a patient truly has resistant hypertension, we verify: Are the medications being taken consistently and at optimal doses? Is the BP measurement accurate (white-coat effect ruled out via home/ambulatory monitoring)? Are there dietary, medication, or substance contributors (NSAIDs, excess sodium, alcohol) undermining the treatment?
For confirmed resistant hypertension, the clinical investigation expands: aldosterone-to-renin ratio, renal artery imaging, sleep study, and 24-hour ambulatory BP monitoring become standard. The answer is often found in these tests.
Can hypertension be cured?
Primary (essential) hypertension cannot typically be cured in the way an infection is cured — but it can often be controlled to normal ranges, and in some cases resolved, when underlying metabolic drivers (excess weight, insulin resistance, poor sleep, high sodium intake) are corrected. Secondary hypertension, caused by a specific identifiable condition, can sometimes be cured or substantially resolved by treating the underlying cause.
The honest framing: for most patients, hypertension management means long-term attention to metabolic health plus medication when needed. For some patients — particularly those with clear secondary causes or those who achieve significant metabolic improvement — medication reduction or discontinuation becomes possible under supervision. We assess your case individually and tell you what is realistically achievable.
High blood pressure in young adults — why this is a specific problem
Hypertension in young adults (typically defined as under 40) is increasingly common in India, and it often has a different driver profile than late-onset hypertension. Secondary causes are proportionally more common in younger patients, metabolic syndrome is frequently present even at normal weight, and the consequences of untreated BP accumulate over decades rather than years.
Young-onset hypertension deserves a more thorough investigation than it usually receives. A 32-year-old with a BP of 150/95 is not the same clinical scenario as a 65-year-old with the same reading — the cause profile, treatment approach, and urgency of investigation all differ. We take young-onset hypertension seriously as an investigation priority, not a “monitor and medicate” afterthought.
What we actually assess — and why it differs from routine BP management
Routine hypertension management in India typically involves a blood pressure reading, a basic lipid panel, a kidney function test, and a prescription. We additionally investigate the underlying driver — metabolic, renal, hormonal, sleep-related, or pharmacological — because knowing the cause changes the treatment plan.
The full assessment covers:
How the hypertension treatment program works
Our hypertension program works on three parallel tracks: first, thorough diagnostic workup to identify underlying and secondary causes that routine care misses; second, structured lifestyle correction built around Indian food, sleep, stress, and movement; third, medication optimisation — adjusting the regimen based on what the workup reveals, not just adding another drug.
Diagnostic workup
The first phase of care establishes what is actually driving your BP. This often reveals an under-appreciated metabolic contribution, an undiagnosed sleep issue, or a medication interaction that standard care missed. Some patients walk away with a fundamentally different treatment plan after this phase alone.
Lifestyle correction structured for Indian patients
Sodium reduction specific to how Indian households actually eat — pickles, papad, packaged namkeen, and restaurant food, not the salt used while cooking. Cooking oil switched from seed oils to ghee. Structured meals to reduce the insulin-driven contribution to BP. Potassium-rich Indian vegetables — palak, methi, lauki — built into the plan. Body weight treated as a measurable clinical lever: meaningful reduction produces reliable, measurable BP reduction.
Medication optimisation — not just reduction
The goal is the right medication regimen for your case, not necessarily fewer drugs. For some patients, the answer is medication reduction as metabolic drivers improve. For others, it is medication adjustment — different class combinations, different dosing times, elimination of interactions — that achieves better control than adding a fourth drug would.
Why home blood pressure monitoring matters more than clinic readings
Clinic BP readings are a single snapshot under conditions that often don’t reflect real life. Home BP monitoring over 7 days, with standardised technique, gives a far more accurate picture — identifying white-coat hypertension (elevated only in the clinic), masked hypertension (normal in the clinic but high at home), and nocturnal dipping patterns that single readings cannot capture.
We teach standardised home monitoring technique (correct cuff size, arm position, timing, and recording) and use the data to make clinical decisions. This is evidence-based care — the 2017 ACC/AHA guidelines and the India Hypertension Control Initiative both emphasise out-of-office BP measurement as more predictive of cardiovascular outcomes than isolated clinic readings.
Hypertension in the Indian patient — why local context matters
An estimated 220 million Indian adults have hypertension, according to the India Hypertension Control Initiative and ICMR-INDIAB data. Indian patients develop metabolic hypertension at lower BMI thresholds, consume dietary sodium patterns that are culturally specific (pickles, papad, masala), and have high prevalence of insulin resistance and visceral adiposity — all of which affect optimal treatment strategy.
Generic international guidelines often don’t account for the Indian phenotype — higher visceral fat at lower BMI, earlier insulin resistance, different dietary sources of sodium, and limited access to ambulatory BP monitoring outside major cities. Our program is built for this reality, not adapted from Western templates as an afterthought.
Who this program is for — and who it is not for
This program is designed for
- Adults with hypertension who want their BP properly investigated, not just medicated
- Patients whose BP is not well-controlled despite one or more medications
- Patients with resistant or suspected secondary hypertension
- Young adults with new-onset hypertension who deserve a thorough diagnostic workup
- Patients with hypertension plus metabolic syndrome, diabetes, prediabetes, or high visceral fat — where the conditions travel together
- Patients who want a realistic conversation about medication reduction based on cause-correction
This program is not designed for
- Acute hypertensive emergencies requiring immediate hospital-level care
- Pregnancy-related hypertension, which requires obstetric-led care
- Patients unwilling to engage with lifestyle factors — medication-only management is available through any GP
- Patients seeking an instant "cure" — hypertension management is typically long-term, even when causes are identified and corrected
Why patients choose Redial over routine hypertension care
Routine hypertension care in India prioritises control of the BP number. That’s necessary but often insufficient. Redial Clinic prioritises identifying and treating the underlying driver — which often achieves better BP control and reduces medication burden simultaneously.
