Hypertension drugs treat a symptom — elevated blood pressure — without addressing the underlying causes. The evidence for their benefit in mild-to-moderate hypertension is weak, and the side effects are substantial.

What Causes Hypertension?

The primary causes of essential hypertension are:

  • Fructose: Fructose metabolism produces uric acid, which inhibits nitric oxide production and causes vasoconstriction
  • Insulin resistance: High insulin levels cause sodium retention and sympathetic nervous system activation
  • Obesity: Visceral fat produces inflammatory cytokines that impair endothelial function
  • Industrial seed oils: Oxidized PUFAs impair endothelial nitric oxide production
  • Sodium: High sodium intake raises blood pressure in salt-sensitive individuals (approximately 50% of hypertensives)

Treating hypertension with drugs without addressing these causes is treating the symptom while ignoring the disease.

The Evidence for Drug Treatment

Severe hypertension (>180/110): Drug treatment clearly reduces stroke and cardiovascular events. The evidence is strong.

Moderate hypertension (160-180/100-110): Drug treatment reduces stroke risk. The evidence is reasonably strong.

Mild hypertension (140-160/90-100): The evidence for drug treatment is weak. A 2012 Cochrane review found no evidence that treating mild hypertension reduces cardiovascular mortality or all-cause mortality.

A 2012 Cochrane review found no evidence that treating mild hypertension reduces cardiovascular mortality or all-cause mortality. Yet mild hypertension is the most common indication for antihypertensive drugs.

The Side Effect Problem

Antihypertensive drugs have significant side effects:

  • ACE inhibitors: Dry cough (10-15%), angioedema (rare but serious)
  • Beta-blockers: Fatigue, sexual dysfunction, masking of hypoglycemia
  • Calcium channel blockers: Peripheral edema, constipation
  • Thiazide diuretics: Hypokalemia, hyperuricemia, glucose intolerance
  • ARBs: Generally well-tolerated, but expensive

Evidence-Based Non-Drug Interventions

Multiple interventions reduce blood pressure without drugs:

  • DASH diet: Reduces systolic BP by 8-14 mmHg
  • Weight loss: Each kg of weight loss reduces systolic BP by approximately 1 mmHg
  • Exercise: Regular aerobic exercise reduces systolic BP by 5-8 mmHg
  • Sodium restriction: Reduces systolic BP by 2-8 mmHg in salt-sensitive individuals
  • Fructose elimination: Addresses the primary cause of insulin resistance-driven hypertension

These interventions address the underlying causes of hypertension rather than merely treating the symptom.
