Hypertension

High blood pressure is a signal from vessels, kidneys, and the nervous system. We look at insulin, minerals, sleep apnea, nitric oxide, autonomic tone, and the environment, alongside your physician.

What you may be noticing

Often nothing at all, which is why high blood pressure is called silent. You may discover it at a routine visit or on a home monitor. Some people notice morning headaches, a pounding pulse, poor sleep, or a sense of pressure in the head. You may already take medication and wonder why the numbers still climb.

A blood pressure reading of 180 over 120 or higher, or high blood pressure with chest pain, shortness of breath, weakness, vision changes, or confusion, needs emergency care immediately. Supplements and breath practices are never the first step in a crisis. I never ask anyone to stop or reduce blood pressure medication; any change belongs with your prescriber.

Why it is rarely one thing

Blood pressure is not one number controlled by one organ. It reflects how relaxed your vessels are, how much sodium and fluid your kidneys hold, and how strongly your sympathetic nervous system is pushing. Family history matters, yet genes describe susceptibility in areas such as sodium handling, the renin and angiotensin system, and nitric oxide production. Environment, food, and nervous system state shape how those genes express.

Insulin resistance is a frequent upstream driver, because high insulin signals the kidneys to retain sodium and stimulates sympathetic output. The inner lining of your vessels, the endothelium and its protective gel layer, releases nitric oxide to relax arteries, and inflammation, high blood sugar, smoking, and toxic exposures reduce it. Sleep apnea raises pressure through repeated nighttime adrenaline surges. Low potassium and magnesium intake, alcohol, poor sleep, and chronic stress add more.

The brainstem continuously reads pressure sensors in the neck and chest and adjusts heart rate and vessel tone. When the nervous system stays in a state of threat, this control system holds pressure higher. That is why I treat the nervous system as a primary lever, not an afterthought.

Patterns we look for

• Insulin resistance: fasting insulin, HbA1c, and waist circumference.
• Sodium, potassium, and magnesium balance and dietary pattern.
• Endothelial health, nitric oxide, and inflammation.
• Sleep apnea and sleep quality.
• Sympathetic drive, vagal tone, heart rate variability, and breathing pattern.
• Kidney function, thyroid function, and aldosterone excess when suspected.
• Lipids, ApoB, and homocysteine as part of vascular risk.
• Genetic susceptibility in sodium handling and nitric oxide pathways, when tested.
• Alcohol, nicotine, caffeine, decongestants, and anti-inflammatory pain medication.

How I evaluate it

I use home readings taken correctly: a validated cuff, seated and rested, no caffeine, nicotine, or exercise beforehand, morning and evening for a week, logged with sleep, stress, and medication timing. These patterns are far more informative than a single office value. The comprehensive functional neurological exam includes autonomic testing, with blood pressure and heart rate lying, sitting, and standing.

Functional labs may include fasting insulin, HbA1c, a comprehensive metabolic panel with kidney function, an advanced lipid panel with ApoB, hs-CRP, homocysteine, magnesium, vitamin D, a thyroid panel, and, where your physician agrees, renin and aldosterone. Screening for sleep apnea is part of the plan.

How we address it

• Coordinate with your physician or cardiologist on medication and monitoring.
• Restore insulin sensitivity with whole-food, phytonutrient-rich nutrition and daily movement.
• Rebalance minerals: potassium-rich vegetables and fruit, adequate magnesium, and sensible sodium.
• Support nitric oxide and the endothelium with nitrate-rich vegetables, polyphenols, and nasal breathing.
• Calm sympathetic drive with functional neurology: slow breathing with a long exhale, humming and gargling for vagal tone, brain and heart coherence practice, and baroreceptor training.
• Screen for and treat sleep apnea, and reduce toxic exposures that strain the vessel wall.
• Build aerobic and strength fitness, which has strong evidence for lowering blood pressure.

Many people hope to need less medication over time. As your physiology changes, your home readings become the evidence your prescriber uses to make that decision with you.

Your blood pressure is information. When the upstream drivers shift, the number often follows.
