High Blood Pressure

High Blood Pressure Has Causes — Most of Them Are Addressable

If you've been told your blood pressure is high and put on medication, you've probably also been told the cause is "essential hypertension" — a clinical-sounding term that essentially means "we don't know exactly why." The standard recommendation is to take the medication and reduce salt and stress.

That's incomplete. While some hypertension is genetic and irreducible, most of what we see clinically has identifiable contributors that are at least partially modifiable: insulin resistance and metabolic syndrome, sleep apnea, chronic inflammation, autonomic dysregulation, magnesium and potassium status, kidney function, hormonal patterns, and chronic stress. Addressing these doesn't always replace medication — sometimes it does, sometimes it allows lower doses, sometimes it adds the protective effects medication alone doesn't provide.

The risks of leaving hypertension untreated are real (stroke, heart disease, kidney damage, vascular dementia), so we don't recommend stopping medication without coordination with the prescribing physician. The opportunity is in addressing root causes alongside conventional management to improve the overall picture.

What's Actually Happening in Hypertension

Blood pressure is the force blood exerts against artery walls. It depends on cardiac output (how much blood the heart pumps) and peripheral resistance (how constricted the arteries are). Either elevated cardiac output, increased peripheral resistance, or both produce elevated blood pressure.

The body has multiple regulatory systems for blood pressure:

The renin-angiotensin-aldosterone system (RAAS). Kidneys release renin in response to low pressure or volume; renin activates angiotensin II (a potent vasoconstrictor); angiotensin II stimulates aldosterone, which retains sodium and water. RAAS overactivity is a common contributor to hypertension and the target of ACE inhibitors and ARBs.

The autonomic nervous system. Sympathetic activity raises pressure (vasoconstriction, increased heart rate); parasympathetic lowers it. Chronic sympathetic dominance — from stress, sleep apnea, inflammation — sustains elevated pressure.

Vascular tone and endothelial function. The endothelium (single-cell lining of arteries) produces nitric oxide, which signals vessels to relax. Endothelial dysfunction — driven by inflammation, oxidative stress, insulin resistance, smoking, and metabolic disease — reduces nitric oxide availability and increases pressure.

Volume regulation. Salt intake, kidney function, hormonal regulation of fluid handling, and venous return all affect circulating volume.

Arterial stiffness. Aging arteries become less elastic. The systolic peak rises (because rigid pipes don't absorb the pulse wave) and pulse pressure (systolic minus diastolic) widens. Calcification, accumulated glycation, and chronic inflammation all drive arterial stiffening.

What Drives High Blood Pressure

Insulin resistance and metabolic syndrome. Insulin resistance directly drives hypertension through multiple mechanisms: sodium retention, sympathetic activation, endothelial dysfunction, and increased vascular smooth muscle proliferation. Many people with hypertension have undiagnosed insulin resistance even with normal fasting glucose. Fasting insulin is the more sensitive test.

Sleep apnea. One of the most underrecognized hypertension drivers. The repeated oxygen drops and sympathetic surges of apneic events drive sustained hypertension that doesn't fully respond to medication until the apnea is treated. Worth screening when symptoms suggest — daytime fatigue, snoring, witnessed apneas, neck circumference.

Chronic stress and HPA dysregulation. Sustained sympathetic activation, cortisol patterns affecting vascular tone and salt retention. Real, measurable, and often the missing piece in young patients with otherwise unexplained hypertension.

Magnesium and potassium status. Both are important for vascular tone and electrical stability. Subclinical magnesium deficiency is widespread and consistently associated with hypertension. Potassium-rich diets reduce blood pressure, particularly in salt-sensitive patients.

Inflammation. Elevated hs-CRP correlates with hypertension and cardiovascular risk. Chronic inflammation drives endothelial dysfunction and arterial stiffening.

Heavy metal burden. Lead and cadmium specifically have well-documented associations with hypertension. Worth considering in patients with significant exposure history.

Hormonal contributors. Hyperaldosteronism (often missed), Cushing's, hyperthyroidism, pheochromocytoma, and obstructive sleep apnea-related hormonal patterns can all drive secondary hypertension.

Kidney dysfunction. Even modest reductions in kidney function affect blood pressure regulation and respond to addressing.

Sodium-potassium balance. Salt sensitivity varies; for some people sodium reduction matters substantially, for others it doesn't. Potassium adequacy from food (vegetables, fruits) often matters more than absolute sodium reduction.

Alcohol. One of the most consistent dietary contributors to elevated blood pressure. Even modest reduction often produces measurable improvement.

Where TCM Comes In

Chinese medicine has been working with what it sees as patterns of upward-rising imbalance for centuries.

Liver Yang Rising. The classical pattern. Headaches (often at the temples or top of head), tinnitus, irritability, red face, sometimes dizziness. Often associated with elevated blood pressure especially in stress-driven presentations. Treatment subdues yang and clears heat.

Liver Fire. More acute and inflammatory — severe headaches, anger, red eyes, bitter mouth, insomnia. Treatment clears fire.

Phlegm-Damp obstruction. Heaviness, brain fog, chest oppression, common in patients with metabolic syndrome and obesity. Treatment transforms phlegm and clears damp.

Kidney Yin Deficiency with Liver Yang Rising. The depleted-but-revved pattern — hot flashes, dry mouth, anxiety, hypertension that's worse at night. Common in perimenopausal hypertension. Treatment nourishes yin and subdues yang.

Kidney Yang Deficiency. Less common in hypertension but present in patients with elevated pressure alongside cold extremities, exhaustion, and edema. Often kidney-disease-related hypertension.

Blood Stasis. Persistent, treatment-resistant hypertension with vascular changes, often after long-standing disease. Treatment moves blood.

How We Approach Hypertension

Hypertension care is collaborative with primary care or cardiology. We don't replace appropriate medical management; we add the upstream and adjunctive work.

Acupuncture has documented effects on blood pressure regulation. Multiple meta-analyses have shown modest but real reductions in blood pressure with regular acupuncture, with effects on autonomic balance, vascular tone, and stress response. The effect is greater with consistent treatment and lifestyle intervention than acupuncture alone.

Chinese herbal medicine for the specific TCM pattern. Several formulas have direct research evidence for blood pressure reduction. Selection requires expertise, especially with patients on antihypertensives — some herbs additively lower pressure, which can be useful but requires careful coordination.

Functional medicine workup. Fasting insulin, HbA1c, complete metabolic panel, lipid profile (advanced), inflammatory markers (hs-CRP), red blood cell magnesium, full thyroid panel, aldosterone-to-renin ratio when hyperaldosteronism is suspected, sleep apnea evaluation when symptoms suggest, kidney function, and heavy metal panels when exposure history warrants.

Targeted nutritional support. Magnesium glycinate or taurate at therapeutic doses, potassium adequacy from food, omega-3 fatty acids, CoQ10 (especially if on statins, which deplete it; CoQ10 has direct evidence for blood pressure reduction), L-arginine or L-citrulline for nitric oxide support, beet juice or beet powder for nitric oxide. Hawthorn for vascular and cardiac support. Garlic at therapeutic doses has modest evidence.

Address sleep apnea. When present, formal evaluation and treatment. Hypertension that's resistant to medication often resolves when apnea is addressed.

Stress and nervous system regulation. Slow paced breathing has direct, measurable blood pressure effects. Meditation, vagal tone training, and addressing chronic stress patterns are part of the foundation.

Lifestyle integration. DASH or Mediterranean dietary patterns, alcohol reduction (often dramatic), regular aerobic exercise (proven blood pressure effect), strength training, weight management when relevant, sleep optimization.

Medication coordination. When the underlying picture improves, blood pressure often follows — sometimes meaningfully. We coordinate with prescribers when medication adjustments become appropriate. We don't recommend stopping antihypertensives without that physician's involvement.

When to Consider Us

• You've been newly diagnosed with hypertension and want to address upstream drivers
• You're on antihypertensive medication and your numbers still aren't optimal
• You have hypertension alongside metabolic syndrome, diabetes, or insulin resistance
• You suspect sleep apnea is contributing to your blood pressure
• You have stress-driven blood pressure patterns
• You're experiencing significant medication side effects and want to explore options
• You have hypertension in pregnancy or postpartum (we coordinate carefully with OB)
• You want comprehensive cardiovascular prevention beyond just blood pressure numbers
• You have a strong family history and want proactive integrative care
